Setup
Follow these steps for the initial setup of your GD-313 grinding machine:
- Unpacking: Carefully remove the machine and all included accessories from the packaging. Inspect all components for any signs of shipping damage. Retain the packaging for future storage or transport.
- Placement: Position the grinder on a stable, flat, and clean workbench. Ensure there is adequate space around the machine for safe operation and ventilation.
- Power Connection: Connect the power cord securely to the machine's power inlet, then plug it into a grounded 220V power outlet. Ensure the machine's power switch is in the "OFF" position before connecting to power.
- Grinding Wheel Installation: The machine typically comes with an SDC grinding wheel pre-installed, which is suitable for carbide milling cutters. If you intend to grind HSS (High-Speed Steel) milling cutters, you will need to replace it with a CBN grinding wheel (sold separately). Refer to the maintenance section for instructions on changing grinding wheels.

Operating Instructions
This section details the steps for sharpening milling cutters using the GD-313 machine. Always follow safety precautions.
- Select Collet: Choose the appropriate collet that matches the diameter of your milling cutter. The machine supports a grinding range of Ø3mm to Ø13mm.
- Insert Milling Cutter: Securely insert the milling cutter into the selected collet. Ensure it is seated correctly and tightened firmly to prevent slippage during grinding.
- Adjust End Angle: Set the desired end angle for grinding, typically between 0° and 5°, using the adjustment mechanism on the machine. Consult your milling cutter's specifications for the recommended angle.
- Power On: Turn on the machine using the main power switch. The grinding wheel will begin to rotate at 4500 RPM. Allow it to reach full speed before beginning the grinding process.
- Grinding Process: Carefully bring the milling cutter, held in its collet, into contact with the rotating grinding wheel. Apply gentle, consistent pressure. Follow the specific grinding procedure for 2, 3, 4, or 6-edge cutters as indicated on the machine's guide or quick reference chart. Ensure even material removal across all flutes.
- Inspect and Repeat: After grinding, carefully remove the cutter and inspect its edge for sharpness and consistency. Repeat the process if further sharpening is required, making small adjustments as needed.
- Power Off: Once grinding is complete, turn off the machine and allow the grinding wheel to stop completely before removing the cutter or performing any further adjustments.

Maintenance
Regular maintenance is crucial for ensuring the longevity, optimal performance, and safety of your GD-313 grinder.
- Cleaning: After each use, clean the machine thoroughly to remove grinding dust, metal shavings, and debris. Use a soft brush or compressed air. Do not use water directly on electrical components.
- Grinding Wheel Inspection: Periodically inspect the grinding wheel for wear, cracks, or damage. A worn or damaged wheel can lead to poor grinding quality and potential safety hazards. Replace worn wheels promptly.
- Grinding Wheel Replacement: To replace the grinding wheel, first disconnect the machine from power. Carefully remove the retaining mechanism holding the wheel in place. Install the new wheel, ensuring it is correctly seated and secured. Reconnect power and test the machine before full operation.
- Lubrication: Refer to the machine's specific lubrication points (if any) in the included quick guide for periodic lubrication. Use only recommended lubricants.
- Storage: When not in use, store the machine in a dry, clean, and dust-free environment. Protect it from extreme temperatures and humidity.
