Hi all,

Just looking for some advice on milling a Macor part on a Hurco VM1. Following the recommended feeds and speeds from the manufacturer guidelines my machining time according to RhinoCam is 110 hours, completely unacceptable for my production schedule. The part is quite intricate and I have to use 2mm diameter endmills and ballnose mills, unfortunately the recommended feed for these tools is around 15mm/min with max spindle speed at 2000rpm. Does anyone have experience of machining Macor with tools of this diameter, and if so have you tried faster feeds/speeds with any degree of success? Any help would be greatly appreciated!
