Serious personal injury may occur. The Models G1004/08 feature an R-8 spindle which accepts many industrial collets and arbors. To install a collet or an arbor: 1. Release the latches on the head lid and open it. 2. Determine the location of the pin inside the spindle. 3. Align the keyway of the collet to the side where you found the pin and insert the col- let or cutting tool’s arbor up into the spindle housing. Rotate the collet slightly to line up the keyway with the pin in the spindle bore. -11- G1004/1008 Vertical Milling Machine 4. Turn the hex head at the top of the drawbar (located on the top, front of the head) clockwise until the threads at the bottom of the drawbar mesh with the female threads in the top of the collet or arbor. 5. When using a collet: Insert the cutter in the hole at the bottom of the collet and continue to tighten the drawbar until both the col- let and cutter are tightly in place. Do not over-tighten the collet. Grasp the rim of the front pulley. Hold it tight while tightening the draw bar. To remove a collet or an arbor: 1. Loosen the hex head at the top of the draw- bar (2 or 3 turns). 2. Tap on the top of the drawbar with a soft faced mallet to loosen the collet from the spindle. Hold the collet/cutter with a shop towel from the bottom to prevent it from dropping completely out of the machine. 3. Continue to turn the drawbar counterclockwise until it is free from the collet. Once loose, remove and replace with your desired collet. Remove cutting tools from spindle when not in use. Fly Cutter Your mill comes equipped with a fly cutter that fits on the 1" stub end of the R-8 arbor (this comes installed in the spindle). To install the fly cutter: 1. Clean any accumulated grease, oil, or debris off of the R-8 arbor. 2. Fit the fly cutter onto the stub end of the arbor so the keys on the arbor and the keyways on the fly cutter come together. 3. Secure the fly cutter to the arbor with the cap screw and washer provided. Tighten with an 8mm Allen® wrench. 4. Install the arbor with fly cutter into the mill as described under the heading “Collet or Arbor Installation.” Knee Crank Handle The Knee hand crank is located to the left of the Y-axis. It is shipped from the factory with the handle installed on the knee gear shaft backwards. To install properly begin by removing the external retaining ring on the end of the shaft. Slide the handle off of the shaft and re-install so that the handle faces outward. G1004/1008 Vertical Milling Machine -12 SECTION 5: OPERATIONS Test Run DO NOT attempt to investigate or adjust the machine while it is running. Wait until the machine is turned off, unplugged and all working parts have come to a rest before you do anything! Serious personal injury could occur. Turn on the power supply at the main panel. Press the START button. Make sure that your finger is poised on the STOP button, just in case thereOs a problem. The mill should run smoothly, with little or no vibration or rubbing noises. Strange or unnatural noises should be Speed Changes investigated and corrected before operating the machine further. If noises occur that can not be found by visual The motor is mounted on a plate hinged to the inspection, feel free to contact our service depart- column. The motor assembly can be released by ment for help. turning the handle at the side of the motor. Once the motor tension is released, the belts can be easily re-positioned to change speeds. See the speed chart below for belt settings. A speed chart is also located inside the pulley cover. BELT POSITIONING CHART This diagram shows belts positioned at A and II. As the chart shows, these positions will yield 1720 RPM. -13-G1004/1008 Vertical Milling Machine SECTION 6: ADJUSTMENTS Graduated Dials The graduated dials on the handwheels for the table and fine feed can be indexed or “zeroed” to help make accurate and convenient movements. Each dial can be reset or locked with the setscrew or thumb screw provided. Example: Suppose you want to drill a series of holes in a workpiece at 0.625" centers. After locating the first hole’s placement and drilling, you can set the dial of the appropriate axis to zero and move the table 0.625". Drill the next hole and proceed as above. Spindle Height You have two options for spindle height adjustment: a drill press style, levered downfeed and a micro adjustment handwheel. The lever is located on the right, forward portion of the head. The micro adjustment handwheel is to the left. To operate the feed lever: Pull the lever toward you. The spindle will go down until you stop pulling or until it hits the depth stop. To operate the micro-adjustment handwheel: 1. Tighten the knurled locking knob located on the left side of the headstock and just behind the fine downfeed handwheel. 2. Locking out the levered downfeed will transfer control to the handwheel. The handwheel will not function if the knurled locking knob is loose. 3. Loosen the setscrew on the knurled surface of the...
