Getting creative with punch tooling

April 15, 2008 | By Andy Spence-Parsons

Keeping a lean program running takes time, effort, and teamwork. To make the most of lean—that is, to understand all of their options in eliminating waste—companies that do extensive work in punching should keep up with innovation in punching tooling. Two such innovations are tools that tap holes and tools that make tabs for sturdy locking joints.

Advances in automation broaden punching capabilities

July 10, 2007 | By Anthony Marzullo

Increasingly metal fabricators are turning to automated equipment to reduce production downtime and costs, streamline manufacturing, minimize material handling, and address a shortage of skilled labor. Automating punch press operations can range from adding a simple load/unload device to implementing a midlevel material handling system or lights-out production cell to robotics and full tower and storage capabilities. Deciding whether to add automation depends largely on the application.

Punching through complacency to win a bid

January 9, 2007

Anderson Metals, a sheet metal fabricator with clients such as Volvo, Deere, and Cat, needed some specialized tooling in a hurry to win over a new client, Eaton Electrical. Its main punch provider didn't have the tooling in its inventory, so Anderson had to shake off the complacency that had set in and find another supplier. Happily, it found one that had the tooling in stock.

The formula for successful punching

August 8, 2006 | By Andy Spence-Parsons

While the first step in successful punching is to pay close attention to the quality and features of punching tooling, other factors come into play. Punched slugs are clues, and examining them can reveal whether the punch and die clearance is too loose or too tight and whether the machine is properly aligned.

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.

Solving pierce punch breaking and chipping problems

February 8, 2005 | By Art Hedrick

Figure 1Having a pierce or perforating punch chip, or worse yet break, can cause severe die damage. It also can result in nonconforming parts because of burrs or undersize holes. Broken punch pieces can fall into the die and crush pads, as well as forming and cutting sections. This article...
