operation guide

Step 1: Machine Setup
Ensure the machine is placed on a stable, vibration-free surface. Power on the machine and check the lubrication and coolant systems. Install the appropriate grinding wheel based on the material and internal geometry requirements.
Step 2: Workpiece Preparation
Secure the workpiece firmly in the chuck or fixture. Align it precisely to avoid imbalances during grinding. Use a dial indicator to verify concentricity and positioning.
Step 3: Grinding Parameters Setting
Set the grinding wheel speed, feed rate, and depth of cut according to the material and desired finish. For example, hardened steel may require a slower feed rate and finer grit wheel.
Step 4: roughing and Finishing

Start with roughing passes to remove excess material, then switch to fine finishing passes for high accuracy. Monitor the process to ensure consistency.

Step 5: Quality Check
After grinding, measure the internal dimensions using precision instruments like bore gauges or CMMs. Adjust parameters if deviations are detected.
Step 6: Clean and Maintain
Clean the machine and workpiece after use. Regularly inspect the grinding wheel, coolant, and lubrication systems to ensure optimal performance.
