[Case Study] Cost Reduction through Centerless Continuous Grinding Processing

As the production quantity increases, it becomes possible to reduce the total cost.

We would like to introduce a case where cost reduction was achieved through centerless continuous grinding of workpieces with step shapes that cannot stand on their own. There are workpieces with step shapes and thin shapes, but in this case, both were unbalanced and could not stand on their own. Unless specified in the drawings, end face grinding is usually not performed, which leads to variations in end face turning accuracy and poor contact between workpieces, making it easier for the workpieces to fall over during centerless grinding. Therefore, weights are placed on both sides of the workpieces, and grinding is performed by clamping them a little at a time. As a result, the time required for setting the workpieces became longer than the processing time for centerless grinding. [Before Improvement] ■ Workpieces with step shapes and thin shapes are both unbalanced and cannot stand on their own. ■ The time required for setting the workpieces increases due to the risk of them falling over. *For more details, please refer to the PDF document or feel free to contact us.
