  • the amount of processing time which can be saved in the practice of the instant invention will depend upon certain variable such ⁇ as the size and type of the parts and the type of media. Where light media are employed, the cutting speed may be increased by as much as l0 to l while in other cases an increase in the order of 2 to 1 'has been realized. Although wear of the media will also increase in proportion to the pressure, it has been found that this rate of increase in not detrimental when the increase in processing speed is considered.
