HPC Jet Case Studies
| SUCCESS STORY | |
|---|---|
| Client with a tool wear problem and excessive machining time. We managed to reduced tool wear, significantly reduced machining time from 30 minutes to 2 minutes with a much excellent surface finish using the HPC/POWER Jet Spindle. The customer could improve the parts per cutting edge by 25 and had productivity savings of 85%. | |
