SUCCESS STORY
Client with a tool wear problem and excessive machining time. We managed to reduced tool wear, advised the customer to use specific tools for aluminum (he was using them for steel in general), significantly reduced machining time from 360 minutes to 183 minutes with a much better finish using the GJET Jet Spindle. GJET was chosen over the HPC due to the limitation on space, otherwise HPC would have been the preferred Jet Spindle for this happy customer.
