Slug Retention Machine
Product Summary
Tired of errant scrap leaving marks and costing you time and money? A slug retention machine prevents slugs/scrap from pulling out of the die cavity onto the die surface during the stamping process. The machine is a pneumatically-powered grinder. It precisely machines a small angled groove into the sidewall of the die cavity in a stamping die. A micrometer, coupled to the drive of the machine’s slide, enables precise movement of the machine’s carriage to enable the depth of the slug retention groove to be precisely controlled.
The Problem
The slug retention groove is machined in at a precise depth and calculated angle to the die surface, which creates a precise amount of interference. During the stamping operation, slugs (scrap) expand into these precision grooves. The expanded slug size prevents them from pulling back up to the top of the die block. This causes it to land onto the die surface where it can cause damage to the strip, final part, or even to the die.
The Solution
A slug retention machine reduces downtime by eliminating the need to stop the press and remove slugs (scrap) off the die and stripper surface. It also eliminates significant quality control costs looking for slug marks, or costly damage to your die. The retention grooves can be machined into the die openings while the die is still in the press, eliminating labor costs for die removal, disassembly and re-assembly. Less labor results in more savings and up time for you,
Features
The machine is less than 8 inches high and features a magnetic base. The base allows it to be mounted temporarily but firmly in place on the die surface during the grooving operation. The machine can also be used to put grooves into die bushings and die inserts, as well as to vent guided stripper openings. At less than 15 pounds, this lightweight unit is easily transportable within a sturdy carrying case. You can use this on dies in the tool room as well as on a die while it’s in the press. It requires only a compressed air connection to operate, and comes with multiple bits and accompanying tools. Best of all, it can easily be set up and operated by a single person.
