Improve Efficiency, Gain Savings By Reviewing Punching Practices
In our latest case study, we take a look at nibbling, one of the easiest ways to increase efficiency and gain savings by eliminating this inefficient fabrication technique. While nibbling works, the process causes problems that affect both the machine and the workpiece. Damaged turret bores, increased product time, and secondary operations to remove rough edges are just some of the problems.
Post-nibbling rework is a common practice in sheet metal fabrication shops that consume valuable resources. Yet a simple change in the punching process and a small investment in tooling can eliminate this practice altogether. In our case study, a manufacturer in central Mexico was punching large circles with three different diameters using a nibbling process, which left very rough edges. The company dedicated two workers entire work shifts to rework the punched holes.
David Inzunza, Mate Sales Engineer for central Mexico, recommended the use of Mate’s tri-radius tool, which is a punch with three different radii in the machine’s auto-index station. Using the tri-radius tool produced blemish-free circles and eliminated the secondary grinding operations. The company gained the equivalent of two operators’ labor reused for other profitable work and reduced annual usage of grinding supplies
