The Cincinnati Centerless Grinder 340-20 is a versatile and efficient machine known for its precision in the manufacturing of cylindrical parts. When properly maintained, it can deliver exceptional performance and longevity. This article provides a comprehensive service guide to ensure your grinder operates smoothly and meets your production needs.
Understanding the Machine
The Cincinnati 340-20 centerless grinder is renowned for its advanced technology and robust design. It operates on a straightforward principle a workpiece is held in place between a grinding wheel and a regulating wheel, allowing for high-speed and high-precision grinding. This configuration is particularly advantageous for producing tight tolerances and superior surface finishes.
Regular Maintenance
1. Daily Checks Before operating the grinder, it’s crucial to perform daily inspections. Check for any signs of wear or damage to the grinding wheels, bearings, and belts. Ensure that all lubrication points are filled with the appropriate oil to guarantee smooth operation.
2. Coolant System The coolant system plays a vital role in both the grinding process and the overall health of the machine. Regularly inspect and clean the coolant tank to prevent contamination. Additionally, check the coolant pumps and hoses for leaks and ensure they are functioning efficiently.
3. Grinding Wheel Dressing The grinding wheel should be dressed regularly to maintain its cutting efficiency and prevent loading. Depending on usage, dressing could be required daily or weekly. Use the appropriate diamond dressers to achieve the desired profile and sharpness of the wheel.

4. Alignment and Adjustment Over time, components may shift, affecting alignment. Regularly check the alignment of the grinding wheels and workpiece support. Adjust the regulating wheel’s position to ensure consistent dressing and avoid defects in the ground components.
Troubleshooting Common Issues
Even with regular maintenance, issues may arise. Here are some common problems and their potential solutions
- Poor Finish Quality If the surface finish is not smooth, first check the dressing condition of the grinding wheel. If it’s dull, dress it. Also, ensure the coolant flow is adequate and the wheel speed is correctly set.
- Vibration Excess vibration can lead to inaccuracies in grinding. Check for unbalanced wheels or worn bearings. Balancing the grinding wheel or replacing the bearings can mitigate this issue.
- Workpiece Slippage If the workpiece is slipping during operation, inspect the regulating wheel’s adjustment. Adjust the angle and pressure as needed to prevent movement.
