Machine Features

Figures 1 and 2 depict the main features of the

Model J-7015 Horizontal Cut-Off Bandsaw. The machine consists of a machine base onto which is installed a saw head.

Figure 1

Machine Base

The machine base consists of a coolant collection pan mounted on two panels that form the legs of the machine. A shelf is provided under the collection pan that supports a coolant tank.

The machine bed mounts on the top of the collection pan. The bed supports the vise and the vise-tightening lead screw.

The coolant tank is equipped with a pump/motor assembly. The pump/motor circulates coolant through tubing to cool and lubricate the saw blade, the blade guides, and the workpiece.

A drainpipe is provided to connect the collection pan to the coolant tank. A screen is provided in the collection pan to screen-out cutting debris as the coolant drains into the coolant tank. Coolant is added to the tank by pouring coolant into the collection pan. The tank is easily removed from its shelf for cleaning and maintenance.

7

Saw Head

The saw head (Figure 2) consists of a drive motor, drive pulleys, gearbox, blade wheels, blade guides and supports, control panel, blade tension/blade tracking mechanism, wire brush, and the saw blade.

The drive motor is mounted on a pivoting plate that swings outward to provide V-belt tension.

The motor is fitted with a step pulley; the V-belt connects to a second step pulley that is mounted on the input shaft of the gearbox.

A speed-reducing gearbox is mounted on the back side of the blade wheel box on the right side of the machine. The blade wheel (drive wheel) is installed on the output shaft of the gearbox.

A second blade wheel is located in a blade wheel box on the left of the machine. The blade wheel (driven wheel) is mounted on a shaft that is part of the blade tension/tracking mechanism.

The blade tension mechanism is used to tighten the saw blade on the blade wheels.

Figure 2

The mechanism also has adjustment screws that enable the saw blade to “track” evenly on the blade wheels. The adjustment screws change the angle of the driven blade wheel shaft so the wheels are aligned. Tracking adjustments are generally made after the saw blade is changed but may be required periodically due to wear over time.

An electrical enclosure is attached to the leg panel on the right side of the machine. The enclosure contains the switches and fuses required for operation and protection of the drive motor (Figure 3).

Remove the saw from the shipping skid; discard any hold-down devices. Place the saw on the shop floor; secure the saw to the floor using mounting anchors secured through four holes in the machine base. If the saw will be used to cut long pieces of stock, allow plenty of room for the length of the stock.

Minimal assembly is required (see to Fig. 4), consisting of mounting the control box, motor,

pulley guard/cover assembly and motor drive

belt. The mounting hardware is already in place on the saw head. Loosen or remove the hardware, placing the components (listed above) in place and secure. For the drive belt, refer to the Drive Belt section on page 19.

Figure 3

Work Stop

A work stop is provided with the machine to allow cutting multiple pieces of identical length

(refer to Figure 12). The stop consists of a rod onto which is installed a stop bracket, a tapered stop, a clamping knob and a locking handle. The rod is installed in a bore in the front of the saw bed. The stop bracket is positioned on the rod with the tapered stop toward the end of the workpiece. The bracket is moved in or out on the rod to establish the length of the workpiece.

Control Panel

The control panel is mounted on the top of the saw head. Refer to the Controls and Indicators section (page 9) for a description of the controls.

Unpacking and Assembly

Machine Setup

The cut-off saw has been pre-adjusted at the factory and several test pieces have been cut to verify cutting accuracy.

Figure 4

Electrical Connection

Electrical connection must be made by a licensed electrician. The wiring methods and practices must comply with local electrical codes.

The machine uses high voltage electrical power that poses a significant risk of serious injury or death if proper precautions are not observed

Connect the machine to the electrical power branch circuit (refer to the Wiring section on page 31). Observe the following guidelines when connecting the saw to the power source.

1. Make sure the saw is disconnected from the electrical power branch circuit (trip the required circuit breakers or remove the required fuses).

2. Place a warning placard or tag on the service panel to prevent accidental electrical shock.

3. When installing the motor power cord into a receptacle, make sure the plug is compatible with the receptacle. connect the wires as shown in the Wiring

Data section.

5. Install the fuses or reset the breakers.

Check operation of the saw.

Controls and Indicators

Control Panel

The operating controls for the cut-off saw are located on the control panel (Figure 5) and consist of the following controls and indicators:

Coolant Pump Switch – turns the coolant pump on and off.

Emergency Stop Switch – press to stop the drive motor. Note: A micro switch also stops the motor when the workpiece is cut and the saw head is completely down.

Start Switch – press to start the drive motor. The saw head must be in the raised position.

Power Light – indicates that machine is plugged in and the outlet circuit breaker is turned on. The machine does not need to be running for the power light to be on.

Feed Rate Control – this knob is used to set the amount of downward force that is applied to the saw blade. The feed rate is proportional to the opening of the valve. When set to zero, the saw head is locked in the raised position. Increasing the valve opening (counterclockwise adjustment) increases the feed rate; decreasing the valve opening (clockwise adjustment) reduces the feed rate.

Blade Speeds

The Model J-7015 horizontal cut-off bandsaw has four blade speeds. The different speeds are obtained by changing the position of the motor drive V-belt on step pulleys. Change blade speeds as follows:

1. Disconnect the electrical power from the cutoff saw branch circuit to prevent accidental motor start-up

2. Set the saw head at the fully down position.

3. Remove the knob from the drive belt cover.

Swing cover out and downward to expose the V-belt and pulleys.

4. Loosen the drive motor locking handle. Pivot the motor inward to slacken the belt.

5. Select the speed using the placard on the cover. Put the V-belt in the pulley grooves of the pulley for the desired speed. Refer to

Figure 6 for belt locations and the speeds available.

7. Check V-belt tension by pushing the V-belt firmly downward; press down about midway between the pulleys. When properly tightened, the V-belt should depress no more than the width of the belt.

Blade Selection

The cut-off saw is delivered with a saw blade that is adequate for a variety of cut-off jobs on a variety of common materials. A 10-tooth, general-purpose blade is provided as standard equipment with the machine.

Refer to Figure 6 for the speeds recommended for various materials. These speeds, while appropriate for many common shop cutting needs, do not encompass the wide variety of special blade configurations (tooth pitch and set) and special alloys for cutting unusual or exotic materials.

A coarse blade could be used for a solid steel bar, but a finer tooth blade would be used on a thin-wall steel tube. In general, the blade choice is determined by the thickness of the material; the thinner the materials; the finer the tooth pitch.

A minimum of three teeth should be on the workpiece at all times for proper cutting. The blade and workpiece can be damaged if the teeth are so far apart that they straddle the workpiece.

For very high production on cutting of special materials, or to cut hard-to-cut materials such as stainless steel, tool steel, or titanium, you can ask your industrial distributor for more specific blade recommendations. The supplier that provides the workpiece material should be able to provide you with very specific instructions regarding the best blade (and coolant or cutting fluid, if needed) for the material or shape supplied.

Blade Break-in Procedures

New blades are very sharp and, therefore, have a tooth geometry that is easily damaged if a careful break-in procedure is not followed.

Consult the blade manufacturer’s literature for break-in of specific blades on specific materials.

However, the following procedure will be adequate for break-in of JET-supplied blades on lower alloy ferrous materials.

1. Clamp a section of round stock in the vise.

The stock should be 2 inches or larger in diameter.

2. Operate the saw at low speed. Start the cut with a very light feed rate.

3. When the saw has completed 1/3 of the cut, increase the feed rate slightly and allow the saw to complete the cut.

4. Keep the hydraulic cylinder needle valve in the same position and begin a second cut on the same or similar workpiece.

5. When the blade has completed about 1/3 of the cut, increase the feed rate.

Watch the chip formation until cutting is at its most efficient rate and allow the saw to complete the cut (refer to Evaluating Blade

Efficiency on page 10). The blade is now considered ready for use.

Operations

Hydraulic Feed Control

The weight of the saw head provides the force needed to cut through the workpiece. The cut-off saw has a hydraulic cylinder that controls the feed rate of the saw.

The hydraulic feed control circuit consists of a single acting hydraulic cylinder (Figure 7) and a

feed rate control (Figure 5). The feed control cylinder resists motion in the downward direction to control the feed rate. The control cylinder offers no resistance when raised upward.

The feed rate control knob (Figure 5) controls the rate at which the saw head is lowered. The control knob (needle valve) controls the rate at which the hydraulic fluid is released from the hydraulic cylinder. When the needle valve is closed, the cylinder is locked. With the needle valve slightly open, the cylinder permits slow, or light, downward force. Opening the needle valve further increases the feed rate and applies more weight to the saw blade and workpiece.

The needle valve is adjusted until the saw is operating efficiently. The efficiency of operation is usually evaluated by observing chip formation.

Blade efficiency is further described below.

Figure 7

10

Evaluating Cutting Efficiency

Is the blade cutting efficiently? The best way to determine this is to observe the chips formed by the cutting blade.

If the chip formation is powdery, then the feed is much too light, or the blade is dull.

If the chips formed are curled, but colored – blue or straw colored from heat generated during the cut – then the feed rate is too high.

If the chips are slightly curled and are not colored by heat – the blade is sufficiently sharp and is cutting at its most efficient rate.

Work Setup

Referring to Figure 8:

2. With the lifting handle (A) raise the saw head (B). wise enough to free the moveable vise

jaw (E). Then pull the moveable vise jaw away from the fixed vise jaw (H).

4. Place the workpiece (F) on the work table (G).

For long workpieces, provide support at the other end. If necessary, provide additional downward clamping to hold the workpiece securely on the worktable. pushing the moveable vise jaw (E) against the workpiece. Then rotate the vise hand-

wheel (D) clockwise to secure the workpiece.

Setting The Vise For Angle Cuts

Referring to Figure 9, the vise can be adjusted through a 45-degree arc as follows:

fixed vise jaw (D). angle, setting it to the scale on the back edge of the table.

For accurate cuts, use a variable protractor to set the position of the jaw, aligning one side of the protractor with the blade.

4. Loosen the hex head bolt (A) on the

moveable vise jaw (C).

5. Place the workpiece (B) between the vise

jaws (C, D). against the side of the workpiece (B) and

fixed vise jaw (D).

7. Tighten the hex head bolt (A) on the moveable vise jaw to secure the jaw.

Figure 9

Setting the Vise for Square Cuts

The procedure for setting the vise for square cuts is identical to setting for angle cuts (above) except that a machinist’s square is used to set the angle of the fixed vise jaw (J, Fig. 10). Align one side of the square with the side of the slot

(G, Fig. 10) in the table.

Figure 8

Figure 10

Starting the Saw

Important: The efficient operation of the cut-off saw is dependent upon the condition of the saw blade. If the performance of the saw begins to deteriorate, the first item that you should check is the blade.

If a new blade does not restore the machine’s cutting accuracy and quality, refer to the troubleshooting guide (or the blade manufacturer’s guide) for conditions to consider and adjustments that can be made to increase the life of the blade.

To change the blade, refer to the Changing

Blades section on page 18.

Never operate the saw without blade covers in place.

Make sure the blade is not in contact with the workpiece when the motor is started. Do not drop the saw head on the workpiece or force the saw through the workpiece.

To start the saw:

1. Clamp the workpiece in the vise. Refer to

Figure 11 for examples of workpieces in the vise.

Be sure the blade is not in contact with the workpiece when the motor is started.

2. Start the motor and allow the saw to come up to speed.

3. Slowly set the saw down onto the workpiece and adjust cutting speed with the feed control knob (described on page 9).

4. Do not drop the saw head or force the

cut. Let the weight of the saw head provide the cutting force.

5. The saw will automatically shut off at the end of the cut.

Coolant Flow and Nozzle Position

The coolant pump must be submerged before operating to prevent damage to the pump.

Adjust the coolant flow shut-off valve at the top of the saw head weldment. The flow should be no more than the saw blade can draw into the workpiece by the movement of the blade.

The coolant flow can be stopped in two ways:

‰ by the coolant selector switch (A, Fig. 4) on the control box (the preferred method)

‰ by closing the shut-off valve

Note: The coolant pump is self-circulating when the shut-off valve is closed.

Setting the Work Stop

Referring to Figure 12:

The work stop is an accessory that is included with the JET J-7015 Bandsaw. It is used to set up the saw for making multiple cuts of the same length.

Do not allow the blade to rest on the workpiece when the saw is not

cutting.

Thread the stop rod (A) into the threaded opening the on the front of the saw bed (B) as shown.

Set the work stop as follows: to obtain the desired length of cut on the

workpiece (D). end of the workpiece (D).

Figure 12

Adjustments

Blade Tracking Adjustment

Refer to Figures 13 and 14.

Blade tracking has been set and tested at the factory. Adjustment is rarely required when the blade is used properly or if the blade is correctly welded.

If adjustment is needed:

1. Using the blade tension handwheel (D), make sure the blade is properly tensioned.

Note: Blade tensioning is described in the

Changing Blades section on page 18).

Keep proper tension at all times.

4. Remove both of the blade-guide bearing bracket

assemblies (C).

weldment (G).

While performing the following, keep the blade from rubbing excessively on the shoulder of the wheel. Excessive rubbing will damage the wheel and/or the blade.

6. Start the saw. Turn the adjustment screws (F) to tilt the idler wheel (Figure 14) until the blade is touching the shoulder of the idler wheel.

Note: As a general rule, make the same adjustment to the two adjustment screws on the right (F). The single adjustment on the left is independent.

7. Next, turn the adjustment screws (F) so the blade starts to move away from the shoulder of the wheel – then immediately turn the adjustment screws in the other direction so the blade stops – then moves slowly toward the shoulder.

Keep fingers clear of the blade and wheel to avoid injury.

8. Turn the adjustment screws (F) to stop the motion of the blade on the wheel as it gets closer to the wheel shoulder.

Put a 6-inch length of paper (J, Fig. 14) between the blade and the wheel as shown (the saw is still turned on). The paper should not be cut as it passes between the wheel shoulder and the blade.

Figure 13

Figure 14

Repeat the insertion of the paper between the wheel shoulder and the blade until the paper is cut in two pieces.

Note: You may have to repeat the check with the paper several times before the blade and the shoulder cut the paper into two pieces. Do not hurry the adjustment. Patience and accuracy here will pay off with better, more accurate, quieter cutting and much longer machine and blade life.

When the paper is cut:

10. Turn the adjustment screws (F) slightly in the counter-clockwise direction. This assures that the blade is not touching the shoulder of the wheel.

11. Shut off the saw.

12. Tighten the hex locking screws (E).

13. Install the

blade-guide bearing bracket

assemblies (C, Fig. 13).

14. Position the guides so the top bearing just touches the blade (see Blade Guide Bearing

Adjustment on page 16).

15. Close the wheel covers (K, Fig. 14).

Blade Guide Adjustment

Referring to Figure 15:

The J-7015 Bandsaw has two adjustable blade guide assemblies, each consisting of the blade guide

support or bracket (B, H)) and blade guide (A).

The position of the blade guides is important in order to make accurate cuts and prolong blade life and is determined by the size of the workpiece. Adjustment is made as follows:

Left Blade Guide

1. Place the workpiece (G) in the vise (F) and clamp tightly (refer to Work Setup on page 8).

2. Loosen the left lock knob (C) only. just clears the piece to be cut (G).

Right Blade Guide

The right blade guide assembly is set at the factory and rests against the stop (E). It normally does not require adjustment, except to provide clearance for workpieces to be cut at a great angle. If adjustment is required, the procedure is the same as for the left blade guide adjustment.

Figure 15

Blade Guide Bearing Adjustment

Referring to Figure 16:

Guide bearings and guide inserts are located on either side of the saw blade and provide stability for the blade when the saw is in operation. These bearings rotate on an eccentric shaft so the distance from the blade can be adjusted for optimal performance.

Blade guides provide blade support.

Guide bearings and blade guides are initially adjusted at the factory and should rarely require adjustment

It is always better to try a new blade when cutting performance is poor. If performance remains poor after changing the blade, check the blade guides for proper spacing. For most efficient operation and maximum accuracy, clearance between the blade and the guide bearings should be 0.001-inch. The bearings will still turn freely with this clearance. If the clearance is incorrect, the blade may track off the drive wheel.

Disconnect the cut-off saw from

its electrical power source.

Check the blade to make sure the welded section is the same thickness as the rest of the blade. If the blade is thicker at the weld, the guide bearings may be damaged.

If required, adjust first one guide bearing and blade

guide assembly then the other as follows:

1. Using a 3mm hex wrench, loosen two set screws

(A) securing the eccentric bushings.

2. Using a 5mm hex wrench, loosen two socket

head cap screws (D) securing the carbide blade

guides (E).

6. When the adjustment is correct, the guide bearings should rotate freely with slight pressure of the finger (blade stopped).

The V-belt will stretch with use and may occasionally require tension adjustment. To adjust see the Changing Drive Belt section (page 19) steps 1, 2, 6, and 7.

1. Clamp vise and mart top of bar stock here

Verifying Adjustment Accuracy

Refer also to Figure 18.

Rod

Test cuts can be used to determine whether or not you have adjusted the blade accurately. Use 2 inch round bar stock to perform these test cuts, as follows:

1. With the bar stock securely clamped in the vise, make a cut through the bar stock.

2. Mark the top of the bar stock.

3. Move the bar stock about 1/4 inch past the blade so you can begin a second cut.

5. Measure here ...

4. Rotate the bar stock 180 degrees so the mark you made is now at the bottom of the cut.

5. Make a cut through the bar stock.

6. Use a micrometer to measure the thickness variation between the top and bottom of the disk you have cut from the bar stock.

The saw blade can be considered correctly adjusted when the variation measured is no more than 0.012 inch across the face of the disk. If you do not have a piece of 2-inch bar stock available for a test cut, use a larger diameter test workpiece rather than a smaller one. The maximum thickness variation on any test piece should be no more than 0.003 inch, per side, per inch of stock diameter.

6. ... and measure here

2. Cut of a slice of the bar stock

3. Rotate stock in vise so mark is at bottom

7. Difference between measurements at edges of disc should be less than

0.003 inches per inch per side of stock diameter

Figure 18

4. Cut off a new slice from the stock

Switch Adjustment

Disconnect the cut-off saw from its electrical power source.

Referring to Figure 19:

Loosen the jam nut and set the adjustment screw so that the limit switch will actuate to the off position when the saw has cut through the workpiece.

Counterbalance Spring Tension

Disconnect the cut-off saw from its electrical power source.

The counterbalance spring is located on the rear of the saw table (refer to Figure 20). The counterbalance spring is used to adjust the amount of down force the saw arm puts on the workpiece when the hydraulic control cylinder is fully open.

If adjustment is needed:

1. Raise the saw arm to its full upright position and lock it in position.

2. Set the spring tension by adjusting the nut until

1-1/4 to 1-1/2 inches of are exposed on the right side of the eyebolt mount.

The saw can now be returned to service.

Maintenance

Changing Blades

Use leather gloves when changing the saw blade to protect your hands from cuts and scratches. Use protective eye wear that meets ANSI

Specification Z87.1

Disconnect the cut-off saw from its electrical power source.

Referring to Figure 21:

Figure 21

Store the removed blade carefully before proceeding.

6. Slide the new blade into the blade guides

(J), then loop the blade (G) around the drive

wheels (H) such that the teeth face towards the back and the smooth side faces towards the front.

This will permit the vertical side of the teeth to contact the workpiece first.

control knob (B) to zero to lock the hydraulic cylinder, which will hold the saw head in place.

2. Open two hinged blade wheel covers (C).

3. Remove the blade guard (D) and column

blade cover (E). clockwise until the blade (G) hangs loose.

5. Using leather gloves to prevent cuts and scratches, pull the blade (G) off the drive

wheels (H) and out of the blade guides (J). the shoulders of the wheels (H).

When it is seated against the shoulder, turn the blade tension handle (F) clockwise to increase the tension. Do not over-tension the blade; tighten it just enough so it does not slip while cutting.

8. When the blade is properly tensioned, reconnect the saw to the electrical power source.

9. Check and adjust the tracking of the blade.

Refer to Blade Tracking Adjustment (on page 14) if necessary.

10. Close the wheel covers (C).

11. Put 2 to 3 drops of oil on the blade.

18

Changing the Drive Belt

Referring to Figures 22 and 23:

Disconnect the cut-off saw from its electrical power source.

1. Set the arm at the full horizontal position.

2. Open the drive belt cover to expose the V-belt and pulleys. the rear under the motor (see Figure 23 for knob direction). Lift the motor upward to loosen the belt.

5. Put the replacement V-belt in the pulley position for the speed you require (refer to the Blade

Speeds section on page 9).

6. Tighten the V-belt by turning the belt tension

adjust knob (see Figure 23). The belt must be secure enough so it does not slip when the machine is running. Do not over tighten. This will cause premature wear on belt and pulley bearings.

Replacing the Drive Motor

Disconnect the cut-off saw from its electrical power source.

Referring to Figure 24:

1. Remove the drive V-belt (see Changing the

Drive Motor Belt above).

2. Open the motor junction box and disconnect the power cord wires from their terminals.

3. Remove four screws and washers (A) that secure the motor (B) to the mounting plate (C).

4. Installation of a new motor is a reversal of the above steps. Also, complete steps 6 through 8 in

Changing Blade Speed (page 9) to complete tensioning of the V-belt to the correct tension — use a straight edge to be certain the motor pulley is correctly aligned with the speed reducer pulley.

Cleaning

1. Clean off any preservative on machine surfaces.

After cleaning:

2. Coat machined surfaces of the cutoff saw with a medium consistency machine oil.

Reapply the oil coating at least every six months.

3. Clean up accumulated saw cuttings after use. Make sure the lead screw and rapid nut are kept free from saw cuttings and other material that would cause damage.

4. Clean the chip sludge from the coolant tank.

The frequency should be determined by how often the saw is used.

Lubrication

Lubricate the following components at the specified frequencies and using the lubricants defined as follows:

Ball Bearings – the bearings are lubricated and sealed – periodic lubrication is not required.

Blade Guide Bearing – the bearings are lubricated and sealed – periodic lubrication is not required.

Upper Wheel Bushing – six to eight drops of oil each week.

Pivot Points, Shafts, and Bearing areas – six to eight drops of oil each week.

Coolant

Change coolant on a frequency appropriate to the type of coolant being used. Oil based coolants can sour. Refer to the coolant supplier’s instructions for change frequency.

The general-purpose coolant is a mixture of water-soluble oil and water. Mix one part of soluble oil to ten parts of water (one quart of oil to ten quarts water). The eleven quarts of coolant is the amount required for the coolant pump to operate properly.

There are numerous coolants on the market that are formulated for special applications. Consult your local distributor for details in the event you have a long range production task, or are required to cut some of the more exotic materials.
