MINI LINEAR SCALE

TYPICAL L.ATHE ,RE'TRO-FIT

SMALLEST IN SIZE,

BUT BIGGER IN PERFORMANCE.

The Series XT-200 Linear Scale is the smallest

DRO scale on the market today. Being only

06" deep and OQr high. the XT Series is approximately25% smaller than other similar glass scales For the tirst time ever. it is not necessary to pay thousands of dollars for a

DRO system that will fit in those minute areas.

Space-age technology and micro-electro­ nics have shrunk

the

scale. reader head. and increased accuracy. reliability. per­ formance and cost effectiveness. Metrilon wear pads are permanently masked on the optical encoders to automatically set an accurate 1 mil air gap between the moving and stationary components of the encoder.

Metrilon is a new technology which has proven to be

cost

effective. improve perf­ ormance. and reduce size of optical encoders.

RELIABILITY WITH PERFORMANCE

New technology not only allowed the XT

Series to be the smallest glass scale on the market. but it also promoted improvements in reliability. performance and reduced cost.

These improvements were realized by unit­ inQ miniaturized ball-bearing rollers. metrilon reticle pads. new solid state electronics and inovative packaging

Incorporating metrilon encoder reticle pads nos significantly reduced the air gap degradation that has plagued other similar type scoles. Conclusion of extensive tests have depicted little or no pad wear after a million inches of travel.

Using ball-bearing gUides has notedly reduced wear as the encoder slides up and down the glass scale. improved repeat­ ability. and accuracy. and also reduced hysteresis error.

Using the latest solid state electronics, including long-life infrared ligilt sources, has allowed only the optics to be incorporated in the encoder Sub-miniature signal con­ ditioning, analog to digital conversion and amplification electronics have been combined into the external interfacing cable connector This feature hos reduced encoder weight by more than 5()%, therefore further reducing encoder wear and hysteresis error.

Additional features of these exclusive engineering achievements are: rninio tu rized plug- in bipolar integrated elec­ tronics packaged externally from the scale/ encoder makes repairs simple. reduces packaging and environmental cost. and furthermore increases slew rates up to 45 inches per second.

ACCURACY

The XT-200 Series accuracies are assured by using vacuum deposited chrome on soda lime glass scoles. Each chrome line Width is held at on incredible tolerance of better than 45-55'Yo of a cycle Accuracies of better than 50 micro inches have been assured by generating replication masters with ad­ vanced numerically controlled laser inter­ ferometer techniques that are traceable to

National Bureau of Standards. Environ­ mental conditions have been stringently controlled With seismic isolation facilities, temperature uniformity of better thon 0.01'

100 SERIES SCALE ASSEMBLY

6NSTAlLATION PROCEDURES

A.

INn~ODUCTION:

The following instructions are guidelines for in­ stallation of SARGON'S 100 Series spar, glass scale and encoder assembly.

NOTE

This manual describes installation procedures for Bridgeport type knee mills. All part numbers are located on individual hardware kit drawings lo­ cated in each hardware kit. To order replacement or additional parts, use the kit part number and machine manufacturer reference, as some di­ mensions and parts may vary bet­ ween manufacturers.

NOTE

Other machine types may require spe­ cial hardware fabrication. The actual scale installation in all cases, follows the same concepts, custom installa­ tions may be completed without assistance; however, factory assis­ tance is available if necessary.

The spar, glass scale, and encoder assembly have been factory aligned and shipped as a complete unit. Twotemporary#4-40screwsand metal stand­ offs, Fig. 1 B Index 1 & 2, hold the encoder "fin" in its proper aligned position to the spar.

NOTE

Do not remove the temporary/align­ ment screws until the assembly is bolted in place and the installation is completed.

B. IPFUE·H\iSTAlltllTION:

1.

Installation of spar, glass scale and en­ coder assembly on most vertical milling machines is relatively easy and straight forward. STAI\J DARD MACH

C. SPAR AUGNMENT TOlIERAi\'lCIES:

1. Using a depth micrometerordial indicator. indicate the glass scale face surface to parallel the table travel within ±:O.005 inch. Deviations can be corrected by inserting shim stock between the spar and table surface. See Figure 2.

2. Align the glass scale top surface to paral­ lel the table travel within ±O.005 inch.

This alignment can be accurately accom­ plished by using a depth micrometer or dial indicator. See Figu re 2.

NOTE

After installation is completed, it is recommended to recheck ali align­ ment tolerances prior to removing the

"fin" screws and stand-offs, inspect for any movement in the encoder assembly. Any encoder movement will require re-alignment.

A. iJiSPlAV INSTALLATION:

1. Figure 20 depicts a typical Sargon display installation. The first step is to remove the large eye bolt located on top of the milling machine column, Fig. 20 Index 1, and mount the arm (Index 2), as per Fig. 20. The next step is to bolt the display to the display mounting arm with a5/16-18 boltfound in the Hardware Kit. See Figure 20 Index

4.

2. The display can be mounted to the bottom of the mounting arm by removing the screws from the top sides of the display case ex­ trusion and then removing the top and bottom half of the case extrusion. Mount the bottom case half on the top side of dis­ play. Mount the top half of the case extru­ sion tothe bottom half of the display After completion, the top half should now have a mounting hole in its center which you use to bolt to the arm.

NOTE

Cable can be fixed to exit either right or left of the encoder box. Ensure sufficient cable loops to allow the table to move to both left and right extremes without exerting tension on the cable, The cable slack should not lie on the floor, or in a situation where it could get pinched, cut or con­ taminated by toxic chemicals. All damaged cables MUST be replaced.

2. Each cable connector is terminated into its appropriate mating connector located on the back of the display. Example: X axis scale cable assembly connector will mate with the connector called "X-I N" located on back of the display, c'"

2. ZERO the display by pushing the ZERO button. The display should now read

"ZERO".

3. Adjust the machine tool lead screw dial clockwise to read "ZERO".

4. With both machines and display on a

ZERO reference, crank the table and note if the display is counting. If not consult

Section XI (Trouble Shooting Chart Sec­ tion) for guidance.

5. Measure a given travel and compare the lead screw dial to the display. They should be relatively close. If not consult the trou­ ble shooting Section.

6. Tighten the knee and table lock so the table and knee cannot move.

7. Turn the machine tool power on and off several times. The display should NOT add any new numbers to its count. If it does, check the machine and display grounding system.

8. Check and/or adjust the mac hine tools ways, gibs, and lead screw for good con­ dition.

9. Ensure that a #20 ground wire is connec­ ted from the "GND" terminal located on the Display back panel to the "MAINS" earth, ground, such as the conduit for

"AS." buildinq power.

1 O. Proceed to the REPEATABILITY and AC­

CURACY Test below:

REPEATABILITY:

1. Repeatability is verified by this test; Machine tool and Digital Readout performance should be periodically checked by this procedure:

2. Mount a dial indicator on the machine tool table in such a manner that the indicator probe tip touches the scale assembly's black end plate when the table is at one of its positions limits.

3. Set dial indicator and the Digital Readout display to zero.

4. Move the machine tool table to its other

5. extreme then bring the table back just past the indicator zero position. Forward the table to read zero on the Dial Indicator.

Both the Dial Indicator and ORO display should now read zero plus or minus one count.

'E .

Perform step 4 at least three (3) times to ensure good repeatability.

6. If repeatability is not realized as per above, consult the trouble shooting Section on repeatability for guidance.

C. ACCURACY:

1. Accuracy test procedures will only verify the machine tool, and ORO installation accu racy. The Sargon glass scale accura­ cies are at least one thousand times more accurate than most machine tools. Sar­ gon glass scales are traceable to the

National Bureau of Standards (N.B.S.).

2. To check accuracy, place reference stan­ dard such as certified gage block and/or indicator on the working surface of the table. SimUltaneously compare the ORO and reference standard accuracies to each other. Repeat the measurements at least three times. If there is a major discrepancy between the two measurements, recheck the scale installation. Generally speak­ ing, accuracy deviation is contributed to the following: a. Machine tool working area distance from scale. (Abby error) b. Adjustment of machine tool "ways" and "gibs." c. Machine tool basic accuracy. d. Scale encoder installation. e. Scale assembly mechanical align­ ment.

3. For a better understanding of accuracy review Section X (Machine Tool Error) of this manual.

VU. PiRlEVENTA"nVIE MAINTENANCE

A. ClEANBMG:

1. DISPLAY:

Dirt on components acts as an insulating blanket and prevents efficient heat dis­ sipation. It also provides an electrical con­ duction path that can result in instrument failure. The recommended way to clean the interior is to blow off the accumulated dust with dry, low pressure air (approx­ imately nine pounds per square inch). Re­ move any dirt that remains with a soft brush or acloth dampened with a mild detergent and water solution. A cotton-tipped appli­ cator is usefu I for cleani ng narrow spaces, or for cleaning circuit boards. Then blow­ dry the dampened area. a. Exterior areas may be cleaned with a soft cotton cloth, small paint brush, or soft tissue paper. The paint brush is particularly useful for dislodging dirt on, and around, the front-panel controls. Dirt that remains can be removed with a soft cloth or brush dampened in a mild detergent and water solution or isopropyl alcohol.

NEVER USE ABRASIVE OR SOL­

VENTS. b. c.

CAUTION:

The counter display LED filter may easily be scratched when using the above cleaning procedures with dry lense tissue.

Recommended method is:

Gently wash the filter with a soft clean damp cotton cloth and clean water, blow dry with low-pressure dry air.

Greasy residues or dirt may be re­ moved with a solution of warm water and a neutral pH liquid detergent, rub gently with a soft cotton cloth.

After cleaning, a visual inspection should be performed to find such de­ fects as broken connectors, heat damaged and/or loose electronic parts, and loose/broken wires. Overheat­ ing parts usually indicates other pro­ blems or potential trouble in the electronics; therefore, it is recom­ mended to contact the local service center, or the factory.

2 SCALE:

a.

There is no preventive maintenance required for the electronic and opti­ cal circuits within the scale encoder

In everyone to three years, dust, dirt, cutting fluid,

;:>.:lC loose chipping could present a problem. Cleaning pro­ cedures are the same as section 1

a.

above. b. 100 Series glass scales and reticle should be cleaned with isopropyl al­ cohol and dried with a clean cloth or paper towel. Special care should be taken to follow the disassembly and assembly procedures as depicted in the scale installation section. Make sure the scale assembly is secured tightly and aligned properly. c. Cleaning procedure for the XT200

Series miniscale is as follows:

1. Position table so encoder is at one extreme location on the scale housing.

2. Using

no more

than 20 PSI of air, gently insert the air nozzle through the rubber flaps entrance of the scale housi ng and blow air away from the encoder towards other end of the scale.

3. Apply the air pressure in such a manner that dirt and particles will migrate to the other end of the glass scale and fallout

4. Move the encoder to the oppo­ site end of the scale and apply air pressure as per above instruc­ tions.

5. Using a spray dispenser spray and saturate the glass scale with alcohol.

NOTE

Never blow air or alcohol toward the encoder.

6. Using a

"0"

tip or equivalent, gently rub and clean the glass scale.

VUe TROUBLE

SHOOTH\~G

AND

~ER\fICING

A, GENERAL:

1. The following information is provided to facilitate system trouble shooting pro­ cedures and aid the user in communicating problems to the local service center or fac­ tory. It is not necessary to understand the circuit operation to find the sub-assembly that is at fault The factory has individually set up and tested the overall performance before each system is packaged and shipped. In general the system will serve the user without any operating difficulty, and operate to full satisfaction when the system is properly installed and cared for.

2. In the event of an operating difficulty or problem refer to the below appropriate trouble-shooting information guide and see if t he problem can be corrected; if not, contact the local Dealer/Service Center, or factory for advice. Depending on the nature of the problem, it may be necessary to ship one of the sub-assemblies or units back to the Dealer orfactory. The Cou nter mother board or power su pply replace­ ment is easy when instructions are fol­ lowed.

NOTE

Do not ship any package to the dealer or factory without prior notification and approval. In such a case, pac­ kage the components and furnish information as follows: a. If shipping scales, make sure to lock the encoder assembly to the spar as per instructions. b. Install the component in a sturdy box that is well packaged. If possible use the original box received from fac­ tory c. Prepare and enclose in the box a detailed report describing the pro­ blem in full. Address the report to your contact who authorized the ship­ ment d. H ave the freig ht prepaid, and the shipment insured

B. SYSTEM TROUBLE SHOOTI NG

PROCEDURE:

1. FAULT: One axis is malfunctioning or seems erratic:

Procedure: Note the malfunctioning read­ ing and switch the "X" and "Y" encoder cables on the back panel of the display.

Operate the machine as before, and ob­ serve the axis suspected of malfu nction. If the fault still appears on the same axis of the display as before the display is at fault.

If the malfunction has moved to the other axis, the fault is in the scale assembly. To verify the find in g, retu rn the ca b Ies to

t

hei r original connection and repeat the above steps carefully, noting all display readings.

2. FAULT: System does not work and the display LED's do not light up:

Procedure: Check the display power cable to make su re that it is pi ugged into" Mains

Outlet". Ensure power is at the "Mains" outlet socket by plugging in another elec­ trical device, and observe operation. Check display's power fuse located in the back panel of the display. If the fuse has

If the display LED's light up, con nect one scale cable at a ti me u nti I the display LED's light goes out. When an individual scale has been identified to be the fault proceed to Para C. If t he display continues to blow fuses when the scale cable is disconnected, the fault is the dis­ play. c. LINEAR SCALE <rROUBlE SHOOTING:

Ensure the four (4) jack screws in the encoder box are properly adjusted.

5. Ensu re connector that mates with the display connector is secure.

6. If the above possible remedies do not resolve your problem con­ tact your local service center or the factory for guidance. b. FAULT: Scale does not operate.

Possible remedies:

1. Check para C 1 a, 2, 3, 4 and 5 above.

2. Replace encoder I.e. chips

3. Replace encoder reader head.

NOTE

Reader head replacement is simple, see section IX for guidance. Most

Sargon dealers and sales represen­ tatives have spare encoder reader heads. Approximate time required to change a reader head is five (5) minutes. No special tools or elec­ tronic equipment is required.

of

Instruction Manual.

2. Disconnect the red, black, blue and green wires connected to the encoder by gold

"quick" disconnect pins.

3. Gently lift the spring that connects the encoder to the encoder box with needle nose pliers and slide the encoder off the left end of the glass scale.

CAUTION

Place a piece of paper between the glass and spring, so as not to sqr atch the glass.

NOTE

In some cases, the spar mounting bolt may be in the way of the encoder. If so, remove bolt and realign the spar as per Section 1 C of this manual after encoder replacement has been com­ pleted.

4. Slide the new encoder on to the scale and reconnect spring and wires as per below

Fig 25. eescsesssssssas

CAUTION

Do not allow the glass scale to rub, or touch the four (4) each encoder infrared LEO's located on the bottom printed circuit board that sandwiches the glass scale.

NOTE

Prior to installing the new encoder, inspect the encoder spring to ensure it is "loaded" properly. The spring tension should be loaded in such a manner that the eye is firmly resting on the glass scale center open line.

The spring eye should not be 'cocked."

SPRING LOADING !"DJUSTMENT IS

cemented in the spar. Repeat the above step until the spring memory positions the spring eye as per above.

A, For obvious reasons, scales cannot be moun­ ted right where machine work is going to take place. A standard vertical milling machine using linear scales would not have any error if it's table movement followed a perfect straight line. Since this is not always the case, and often tabl e movement deviates somewhat, there will be transfer error. Transfer error refers to the difference between the displacement of the scales reader head and the machine tool cutter.

Some sources of error include the following:

1. Crooked ways.

2. Worn out and loose ways and gibs.

3. Bending and deflection of tables caused by gravity, etc.

4. Deflection and distortion caused by cut­ ting and driving forces.

5. Geometric distortion of machine due to temperature.

An example of non-linear movement is over, hang in knee-type mills. This is shown in Fig.

26. Because of the pull of gravity on the table as it moves to the sides, its movement is likely to conform to a circular arc around a center far below the machine.

To illustrate this concept further, the error is given by the following equation:

E= 8h where E

= error,

= distance between working plane and the measuring plane.

Machine tool errors are not limited to old machines. Large table errors can exist in new machines as well. Askilled machinist can iden­ tify errors of his machine and can compensate for them by either leading or lagging the table and meet required tolerances.

Table movement will deviate somewhat and there will be some transfererror. Transfererror refers to the difference between the displace­ ment of work place and the displacement of the scale's reader head.
