[Examples of Productivity Improvement] Quality Control of Honing Machines

Building a monitoring and control system based on data validation! A case study on preventing product defects in grinding machines.

This is an example of a control system built by introducing the "VD-unit" to a honing machine (grinding machine) and utilizing the differences in processing vibrations caused by play in the equipment. Defects (poor formation of grinding marks) occurred in the products at a frequency of once every few months, leading to increased costs. The cause was due to play in the equipment, and the timing of maintenance relied on the operator's intuition. As a result of verification using the "VD-unit," it was confirmed that there was approximately a 50% difference in vibration values during specific processing before and after maintenance. Based on data verification, a monitoring and control system has been established. [Case Overview] ■ Request: To prevent the occurrence of defective products using the honing machine (grinding machine) ■ Measurement Point: Near the spindle of the grinding blade ■ Solution: - Confirmed approximately a 50% change in vibration values before and after maintenance, and maintenance is performed when changes in vibration values are detected by the VD-unit. *For more details, please download the PDF or feel free to contact us.
