Goal

This hardware manufacturer wanted to improve cycle times, extend tool life, improve their part quality/finish and lower tool costs. To achieve this goal, KYOCERA SGS application engineers looked for a way to improve cutting parameters using a less expensive tool while maintaining excellent quality.

Strategy

By adding a Cool Speed Spindle Speeder to reach 28,000 RPM, and implementing a SGS 3-flute micro end mill, cycle time was decreased roughly 40% and a smoother, burr-free finish was achieved compared to the competitor tool at lower RPMs.

Result

The implementation of the Series M3S resulted in a 37% reduction in machining cycle time. Total machining costs decreased by 37%, and the cost per part was reduced by 36%. Overall, the customer achieved a total cost reduction of 36%, generating annual savings of more than $39,000.
