NC Punching Services
(click on thumbnail to enlarge)
G & M Metal Fabricators offers precision CNC metal forming utilizing cutting edge numerical control systems with press ratings of 20.5 to 33 tons at 20 to 40 stations. We can punch, stamp, blank, pierce and form stainless steel, cold-rolled steel, copper and aluminum and provide secondary, stage, progressive and temporary tooling.
We work with a maximum stock thickness of .125" on stainless steel, .187" on cold-rolled steel and .250" on aluminum. On light gauge, we can handle a minimum hole size of .050" and a maximum of 3.75" without nibbling. We offer +/-.004" repeatability between feature centers and punched hole sizes of +/-.0005" not including the blowout.
In addition to the CNC metal forming services, we offer assembly, hardware and finishing as well as in-house quality inspection and compliance with EIA, NEMA and UL standards. We typically require lead times of six weeks, and can produce volumes from prototype to production volumes.
You can find more detailed CNC metal forming specifications in the chart below and can contact us if you require additional information.
