Site Considerations Site Considerations Floor Load Refer to the Machine Data Sheet on Page 3 for the weight and footprint specifications of your machine. Some residential floors may require additional reinforcement to support both the machine and operator. Placement Location Consider existing and anticipated needs, size of material to be processed through each machine, and space for auxiliary stands, work tables, other machinery, and the operator when establishing a location for your new machine.
Mounting to Shop Floor Mounting to Shop Floor We recommend that you mount your new machine to the floor. Because floor materials may vary, floor mounting hardware is not included. Assembly To assemble your mill/drill: 1. Lag shield anchors with lag bolts and anchor studs (Figure 7) are two popular methods for anchoring an object to a concrete floor. Place the handwheels on the longitudinal and cross lead screws, and tighten the set screw (see Figure 8).
Test Run 5. Once the assembly is complete, test run your machine to make sure it runs properly and is ready for regular operation. The test run consists of verifying the following: 1) The main motor powers up and runs correctly and 2) the stop button safety feature works correctly. ����� �������� ��������� If, during the test run, you cannot easily locate the source of an unusual noise or vibration, stop using the machine immediately, then review Troubleshooting on Page 26.
Break-In After successfully completing the Test Run, it is necessary run the mill/drill in each speed and direction without a load to seat the bearings. NOTICE Only change spindle speed when the spindle is stopped. Attempting to change spindle speeds when the spindle is in motion will damage the drive gears and bearings. 3. Twist the emergency stop button clockwise so that it pops out. 4. Switch the spindle rotation dial to "F" (forward) and let the spindle run for 10 minutes. 5.
SECTION 4: OPERATIONS Control Panel Operation Safety A. Power Lamp: Glows when the master power switch is ON. Damage to your eyes and lungs could result from using this machine without proper protective gear. Always wear safety glasses and a respirator when operating this machine. B. Headstock Up Button: Controls the headstock motor so the headstock is powerfed upwards. C. Headstock Down Button: Controls the headstock motor so the headstock is powerfed downwards. D.
Spindle Height Control Table Travel (X-Axis and Y-Axis) Spindle height is changed by unlocking the quill lock lever and the fine feed knob, and using the quill feed handles or the fine feed knob (Figure 12). The spindle scale indicates the spindle height in inches and millimeters. Longitudinal Feed The longitudinal feed, or X-axis, is moved by the handwheel at the right end of the table. The handwheel will move the table in both directions side-to-side.
Tooling Changes Drawbar Nut Your mill/drill has an R-8 spindle taper. Follow these general procedures to install and remove R-8 tooling like drill chuck arbors, face cutters, or collets of your choice. LACERATION HAZARD! Leading edges of end mills and other cutting tools can be very sharp. Protect your hands with gloves or a shop towel when handling. Figure 14. Unseating the arbor/cutter. 6. Clear away all items from the cutter before turning the mill/drill ON.
Choosing Spindle RPM 2. Measure the diameter of your cutting tool in inches. 3. Use the following formula to determine the needed RPM for your operation: NOTICE Never shift gears while mill/drill or mill is running; otherwise, the gear teeth will be chipped or broken. To determine and set the mill to the needed cutting RPM: 1. Select the cutting speed required for the material of your workpiece using the table in Figure 15.
Milling/Drilling To mill a workpiece: 1. 2. Learn about the control panel shown on Page 16 and the controls shown in Figure 16. Failure to follow RPM and Feed Rate Guidelines may threaten operator safety from ejected parts or broken tools. Spindle Scale Quill Feed Lever Clamp the workpiece to the milling table, and adjust the headstock to the needed height, depth of cut, and milling path.

SECTION 6: MAINTENANCE Always disconnect power to the machine before performing maintenance. Failure to do this may result in serious personal injury. Schedule Cleaning and Protecting Metal chips left on the machine that have been soaked with water-based coolant will invite oxidation and a gummy residue build-up around the moving parts. Use a brush and shop vacuum to remove chips and debris from the working surfaces of the mill.
Lubrication Ball Oilers Lubricate both ball oilers every 8 hours (see Figures 28–29). Use a manual oiler (oil can) filled with ISO 68 or SAE 20W non-detergent oil. To lubricate ball oilers, depress the ball with the tip of the oil can nozzle and squirt a little oil inside the fitting. Make sure to clean the outside of the ball oiler before and after each use to keep out contaminants. Figure 29. Cross slide ball oiler. Ways Clean the longitudinal, cross, and headstock ways of all debris.
Headstock Lead Screw Headstock Gearbox Oil On an annual basis, or every six months under heavy use, we recommend that you clean and lubricate the headstock lead screw with white lithium grease. On an annual basis, or every six months under heavy use, we recommend that you drain and refill the headstock oil with a 10-30W non-detergent oil. To clean and lubricate the lead screw: To change the headstock oil: 1. DISCONNECT MACHINE FROM POWER! 1. DISCONNECT MACHINE FROM POWER! 2.
Troubleshooting SECTION 7: SERVICE Review the troubleshooting and procedures in this section to fix or adjust your machine if a problem develops. If you need replacement parts or you are unsure of your repair skills, then feel free to call our Technical Support at (570) 546-9663. Troubleshooting Motor & Electrical Symptom Possible Cause Possible Solution Motor will not start. 1. 2. 3. 4. 1. 2. 3. 4. 5. 6. 7. 8. 9. Incorrect mill/drill operation. Main power panel switch is OFF.
Adjusting Gibs Longitudinal Gib Adjusting Screw The gibs control the accuracy of the table and headstock movement. During the life of your mill/ drill, you may have to adjust the gibs to remove looseness that is a result of normal wear. The goal of gib adjustment is to remove unnecessary looseness without causing the dovetail slides to bind. Loose gibs may cause poor finishes on the workpiece and may cause undue wear on the slides; over-tightening may cause pre-mature wear.
