To make the best use of servo technology, you must have the best practices, best people in place with ongoing training and support. The first step in getting more out of the servo press is understanding your current processes and their pain points; know your press's capabilities; and understand the critical tolerances for the part--and how servo presses can help overcome limitations.

Q: We recently received an order for domed spring washers stamped from 0.0010-inch-thick 301 1/2 hard stainless steel. The parts are about 0.250 in. OD and have two 0.006-in.-diameter pierced holes on a 0.150-in.-dia. circle centered on the part. We usually do not stamp anything less than 0.010 in....

Lubrication plays an important role in stamping, as it reduces friction at the tool-workpiece interface. Reducing that friction also reduces die and tool wear in large-volume production, which in turn increases tool life. It also allows smoother flow of the sheet material into the die cavity and...
