Powering up with a punch

July 11, 2006

When Generac Power Systems, a generator manufacturer, went looking for ways to increase the useful life of its punching tooling, it tried several strategies before it settled on the Optima® coating provided by Wilson Tool International® Inc. When Wilson later introduced UltimaT, a tool steel, Generac tried it also. Generac eventually converted all of its punch tooling to the new tool steel and coating.

Organizing your chaos

January 10, 2006 | By Joel Pierson

Many fabricators use fairly rudimentary methods to keep turret press punch tooling stored, but often tooling isn't really organized. A common method is to store tooling horizontally and group tooling by station (A-station tools a grouped together, B-station tools together, etc.). Storing them vertically and grouping them by size (all rounds go together, regardless of station) leads to an elegant and simple organization.

Punch Tooling, aka ...

August 9, 2005 | By Andy Spence-Parsons

New types of punch press tooling make it possible to perform many secondary fabricating operations on the turret press as well as standard punching—in some cases eliminating additional equipment and part handling, and reducing machine downtime. Not only are new part features possible on the turret press using these new tools, the reduced costs fabricators may achieve by using these tools to may make the tools a variable in DFM.
