Can you use a vertical cnc mill to punch holes in 3/16" thick silicone rubber by mounting a hammer driven hole punch (1/4" hole) in the spindle? Use the machine to accurately locate a pattern of holes, move to position, travel -z thru the rubber to a delrin backing plate, and repeat to the next location. Spindle is not turning, rubber is clamped to table to prevent movement. Shearing force about 130 pounds.
Machine is a Mazak VC-EZ-20. Thanks
