*Can handle prototypes to larger production runs
*Minimize costs in small to medium production as compared to laser
cutting, water jet, and hard tooled stamping
*Easily implement Engineering Changes without large tooling modification
costs
*Faster than laser cutting
*Suitable for a wide variety of materials

Which one do you guys prefer to work? What about the running costof
both methods?

Punch presses are dirt cheap to run. CNC punch presses are nearly as
dirt cheap to run.

Punch presses require punches. Those can get spendy to make and
replace. The time needed to make one needs to be added to any
"production time" when costing out a project.


Has anyone on the group ever made a bolt driven chassis punch? I
want one for the common as dirt IEC 'C7' connector used for computer
power cords. They sell for around $600, which is out of the question.
