HOW TO CHOOSE A HYDRAULIC PUNCH

A portable hydraulic punch is a machine designed to make holes quickly and easily through steel,aluminum, and other metals. They are designed for applications typically done with hand heldtwist drills or mag drills. Not only are they portable but they provide extra versatility with aunique throat design and the ability to adapt to several punch and die styles. Punching holesinstead of hand drilling saves time, faster cycle times, ease of handling and accuracy, less cleanup (gives you a clean slug that is easy to handle) and the punches last longer.

HERE ARE SOME BASIC QUESTIONS THAT WILL ASSIST YOU IN SELECTING THE PROPERPORTABLE HYDRAULIC PUNCH FOR YOUR APPLICATION:

What is the Size & shape of the hole?round, oblong, square, or other

What is the material thickness?

What is the type of material & profile?steel, aluminum, stainless, etcflat bar, channel, I-beam, angle, etc

What is the distance from the edge tothe hole?

Flat Bar Channel

I-Beam Angle

ANSWERING THE FIRST THREE QUESTIONS WILL DETERMINE THE MINIMUM TONNAGEREQUIRED BY USING THE FOLLOWING FORMULA:

HOW TO CALCULATE THE CIRCUMFERENCE

Round holes multiply the diameter by 3.1416

Square holes measure the length of all four sides

Oblong holes multiply the largest measure of the oblong by 3.1416

Once you have determinedthe minimum tonnage, youwill need to identify thethroat depth in order toselect the best punch foryour production.

Depth of throat ismeasured from the edge ofthe material to the centerof the hole needing to bepunched.

TYPES OF PORTABLE PUNCHES

Single acting hydraulic punches: generally, these punches operate with a self-containedor separate power unit that generates the punch cycle only with a spring return. They are
