Is the 50 inches per minute axis travel speed available while the machine is cutting, otherwise, what is the maximum cutting speed?
Yes, the Jr. and the Supra can cut up to this speed. However, it is best to use the industry standards for proper machining speeds. With regard to machining, working at a high feed speed will break your end mills unless you are cutting through foam, wax, wood, or plastic. Machining a part out of metal at at a low feed rate will best ensure your endmill from snapping.
