Make sure that the spindle has come to a complete stop before changing the spindle speeds, turn off the power and turn the speed change handle to the required position. There are two forms of spindle feed available on this machine, one is the direct feed form: the spindle feed is performed by the drilling handle on the gear shaft directly. Under this condition, the spindle feeds 88mm as the gear shaft turns once. The other form is the micro feed, when the hand feed wheel drives the worm gear through the cone clutch to drive the gear shaft to feed the spindle. The spindle will feed 2.5mm when the micro feed handwheel is turned once. 5 Cleaning 1. This machine has been coated with a heavy grease to protect it when it is delivered, this coating should be completely removed before operating the machine. Commercial degreaser, kerosene or similar solvent may be used to remove the grease from the machine but avoid getting solvent on belts or other rubber parts. 2. After cleaning, coat all bright work with a light lubrication, lubricate all points with a medium consistency machine oil. Lubrication All ball bearings in your mill/drill are sealed for life, requiring no lubrication. Points requiring lubrication are: 1. Internal spline drives assembly. Keep this area well lubricated with good grade non-hardening grease. Insert grease in the hole at the top of spindle pulley spline driver. Lube twice yearly. 2. A light film of oil applied to the quill and column will reduce wear, prevent rust, and assure ease of operation. 3. Quill return spring should receive oil (SAE 20) once yearly. Remove cover plate and apply oil with squirt can or small brush. 4. IMPORTANT: The gear box should be oiled with a lubricant such as SAE 68 oil in level. CHANGE OIL EVERY ONE YEAR. Change the gear oil: Tilt the head stock over as shown in Fig 2. Open the oil drain plug to allow the oil to drain from the opening completely. Then lock the oil drain plug and turn the head to be upright position. Remove the oil filler plug fill the oil to the gear box until the oil lever reach the middle of oil fluid lever indicator. Then lock the plug. 5. Apply Lubricant to quill pinion every 90 days. 6. Note: use extreme care when performing this operation and keep hands clear of pinch points. When using paraffin bar, do this only by turning the sheaves by hand. Do not apply with motor running. 6 Precaution for operation Check all parts for proper condition before operation; if normal safety precautions are noticed carefully, this machine can provide you with standing of accurate service. 1. Before operation a) Fill the lubricant. b) In order to keep the accurate precision, the table must be free from dust and oil deposits. c) Check to see that the tools are correctly set and the work-piece is set firmly. d) Be sure the speed is not set too fast. e) Be sure everything is ready before use. 2. After operation a) Turn off the electric switch. b) Turn down the tools. c) Clean the machine and coat it with lubricant. d) Cover the machine with cloth to keep out the dust. 3. Adjustment of head a) Head may be rotated 360°by loosening the two heavy duty head lock nuts. Adjust the head to the desired angle, and then fix the heavy duty head lock nuts. It is tighten the same time to fix the head if drilling too much. b) Unscrew nuts while the work-piece needs to be bevel drilling turn to the degrees you wish on the scale, and then screw the nuts. Fig.2 4. Preparing for drilling (see Fig.3). Turn off the knob make loose the taper body of worm gear and spring base. Then we decide spindle stroke setting the positive depth stop gauge for drilling blind hole or Free State for pass hole. 5. Preparing for milling (see FIG.3) a) Adjust the positive depth stop gauge to highest point position. B) Turn tight of the knob is use to taper friction force coupling the worm gear and spring base. Then turning the handle wheel by micro set the spindle of work piece machining height. 7 C) Lock the rack sleeve at the desired height with fixed bolt. Fig.3 Quill returns spring adjustment Spring tension for return of spindle, after hole drilling, has been pre-set at the factory. No further adjustment should be attempted unless absolutely necessary. Adjustment will probably be required if a multiple spindle drilling or tapping head is used. If adjustment is necessary, loosen lock screw while holding quill spring housing. Do not allow the housing to turn in your hand, or spring will unwind. Turn entire housing assembly clockwise the number of turns necessary to cause the quill to return to its up position. (Note: The flat of the spring housing pilot is lined up with the spring loading hole on the body of the spring housing.) Reset lock screw make sure point of screw mates to flat on the housing journal. Adjusting table slack and compensate for wear (see fig.4) 1. Your machine is equipped with jib strip adjustment to compensate for wear and excess slack on cross and longitudinal travel. 2. Clockwise rotation the job strip bolt with a big screw for excess slack otherwise a little counter clockwise if too tight. 3. Adjust the jib strip bolt until feel a slight drag when shifting the table. Clamping, table base, and machine base (see fig.4) 1. When milling longitudinal feed, it is advisable to lock the cross feed table travel to insure the accuracy of your work. To do this, tighten the small leaf screw on the right side of the table base. 2. To tighten the longitudinal feed travel of the table for cross feed milling, tighten the two small leaf screw on the front of the table base. 3. Adjustable travel stops are provided on the front of the table for control of cross travel and the desired milling length. 8 Fig.4 To change tool 1. Removing face mill or drill chuck arbor. Loosen the arbor bolt at the top of the spindle shaft approximately 2 turns with a wrench. Rap the top of the arbor bolt with a mallet. After taper has been broken loose, holding chuck arbor on hand and turn detach the arbor bolt with the other hand. 2. To install face mill or cutter arbor. Insert cutter and cutter arbor into the taper of spindle. Tighten arbor bolt detach securely, but do not over-tighten. 3. Removing taper drills. a) Turn down the arbor bolt insert the taper drill into the spindle shaft. b) Turn the rapid down handle rod down until the oblong hole in the rack sleeve appears. Line up this hole with the hole in the spindle. Insert key punch key through holes and strike lightly with a mallet. This will force the taper drill out. 9 Electric system 10 Trouble Shooting Problem Cause Solution • Motor out-of-balance • Balance or replace problem motor • Bad Motor • Replace motor • Over feeding • Reduce feed rate • Dull drill • Sharpen drill • Motor not building up or • Replace or repair motor.
