Set-up Information

Punch and Die Alignment

Alignment of the punch to the die is extremely important to the life of the tooling and quality of the hole being punched. Improperly aligned tools will cause premature wear.

Stripping Forces

Punch ends are usually broken off as a result of improper stripping. For good results the stripper must contact the material in at least two points, 180° apart simultaneously. Stripper should also be adjusted as close to material as possible.

Lubrication

Lubricating the material and the punch with a good grade of cutting fluid will prolong the life of the tooling and reduce stripping forces. (Do not use penetrating oil)

Inspection

*Check that punches mate with dies of proper clearance.
*Clean all surfaces and holders.
*Check for proper fit and tightness of coupling nut to punch stem.

Determining Die Clearance

In order to receive optimum performance it is necessary that proper clearance be used. Without proper clearance, material will not fracture cleanly and excess punching pressures will result.

Punch Alignment Features

Keyways allow for the easy alignment of shaped punches. Please refer to the page of this website for your machine or contact a Piranha Service Representative to help select the appropriate keyways for your machine's punches.

Die Alignment Features

Drill spots, whistle notches and "V" Grooves allow for the easy alignment of shaped dies. Please refer to the page of this website for your machine or contact a Piranha Service Representative to help select the appropriate alignment feature for your machine's die.

Warning: It is the users responsibility to set up and use the machinery and tooling in accordance with local and national OSHA laws and ANSI B11.5 safety standards. Only qualified personnel should be allowed to set up and operate the machine. Use extreme caution at all times.

Caution: Extreme pressures can be generated in metal punching. Use approved guards and safety glasses.
