- Electrical Connection: Connect the machine to a grounded 110V AC power outlet. Ensure the circuit can handle the 1100W (10 Amps) power requirement.
- Initial Checks: Before powering on, manually check all moving parts for free movement. Ensure all fasteners are tight.
5. Operating Instructions
Follow these steps for general operation of the milling drilling machine.
- Power On: Turn on the main power switch. The digital display should illuminate.
- Tool Installation:
- Select the appropriate R8-ER32 collet or drill chuck for your tooling.
- Insert the tool into the collet/chuck and tighten securely.
- Install the collet/chuck assembly into the R8 spindle taper.
- Workpiece Clamping: Securely clamp your workpiece to the cross worktable using the parallel-jaw vice or T-slot clamps. Ensure it cannot move during operation.
- Spindle Speed Adjustment: Use the variable speed control to set the desired spindle RPM (50-2250rpm) based on the material and tooling. Refer to material cutting data for optimal speeds.
- Head Tilt Adjustment (if needed): Loosen the head fixing screws to tilt the machine head to the desired angle (up to ±45° from vertical), then re-tighten securely.
- Positioning: Use the X, Y, and Z axis handwheels to position the workpiece relative to the cutting tool. The precision positioning adjustment scale aids in accurate placement.
- Operation:
- Start the spindle motor.
- Slowly feed the cutting tool into the workpiece using the appropriate handwheel (Z-axis for drilling, X/Y for milling).
- Maintain a consistent feed rate to prevent tool breakage or poor surface finish.
- Monitor the cutting process for chip formation and sound. Adjust speed or feed as necessary.
- Completion: Once the operation is complete, retract the tool, turn off the spindle motor, and then turn off the main power switch. Remove the workpiece.
6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your machine.
- Daily Cleaning: After each use, clean chips and debris from the worktable, spindle, and other surfaces. Use a brush or shop vacuum. Never use compressed air directly on bearings.
