Angle Settings: Shaped tools are positioned standard at 0 & 90
degrees. Other angular settings are available upon request.

Blanking: The punched slug is the finished product. The Punch is supplied without shear and the die size determines the actual blank size.

Burr: The rough edge that protrudes on the bottom side of the hole after punching.

Chisel Shear: Angle grind on Punch face for the purpose of
reducing tonnage.

Cluster: Grouping of round or shaped holes to produce multiple holes in one press stroke.

Countersink: A tool to form a taper in sheet metal to accept a flathead screw or fastener.

Die: A hardened tool that supports the sheet metal as the Punch
penetrates through it. The Die size is determined by the type and
thickness of material being punched.

Die Block: The device that clamps the Die into the C-Frame Holder.

Die Clearance: This is the actual dimension added to the Punch dimension based upon the type and thickness of material being punched.

Die Height: The actual dimension measured from the holder base to the top Die surface.

Emboss: A sunken form in sheet metal without cutting the top material.

Extrusion: A forming operation forcing the material into a larger Die hole. Usually designed for tapping sheet metal or to accept self tapping screws.

Feed Clearance: The opening above the die surface available for
feeding the work piece when the press stroke is in the up position.

Gage: A work stop or pin locating device that positions the material
within a UniPunch system.

Galling: Metal deposits that build up on Punch tips or in Guide
inner diameters.

Gauge: A system of measurement that defines the thickness of
sheet metal.

Guide: The sleeve that supports the punch or its components within the holder.

Guide Assembly: The complete sleeve and stripping mechanism to support the Punch within the Holder.

Heeled Punch: A Punch with a Heel that penetrates the die before
the cutting edges contact the workpiece. Primarily used for edge
notching operations.

Holder: A device that houses Punches, Dies and related
components to form a complete Unit.

Inside Diameter (ID): The internal perimeter of the inside of an object.

Key: The device used to locate and position tooling within the Holder. An example would be the external pin found on most Shaped Punches.

Keyhole: A common special shape found in common part assembly methods. Refer to Technical Information Section.

Knockout: The process of cutting and forming material where the slug is held into the material by tabs. Commonly used in the production of electrical panels and boxes.

Lance and Form: A tool that slits and forms a pocket opening in the part in one hit. Refer to Technical Information Section.

Louver: A special tool designed to cut and form material for air
vent openings.

Lubricant: Used for reducing wear and friction of punching components.

Mounting Systems: Bases for holding UniPunch Tooling and Gages within a Punch Press or Press Brake.

Notching: The process of cutting two or more sides from the edge
of sheet metal or angle.

Outside Diameter (OD): The external perimeter of the outer part
of an object.

Pilot Pin: Locating device found at the base of UniPunch Tooling for positioning Holder to Template.

Punch: The tool used to pierce through sheet metal.

Radius Corner: The corner(s) on the Punch or Die that has
been rounded.

Retainer: A device used to hold a Punch or Guide within the unit.

Shim: A thin metal spacer used to extend the Punch or Die length
after sharpening.

Shut Height: The total height from the base of the Holder to the top of the Punch with the unit in the normal closed position. See Unit pages for individual operating specifications.

Slug: The end result of hole punching or notching. (Usually scrap)

Special Shape: Any shape other than standard. Refer to Technical Information Section.

Standard Shape: A shaped Punch or Die such as obround, square, rectangle, etc. as shown in Technical Information Section.

Stripper Plate: A metal plate designed to surround the Punch to assist in stripping the material from the Punch surface.

Stripping: The process of removing the Punch from the material.

Template: A locating plate for positioning Units in correlation to part being punched.

Tonnage: The measurable force required for punching and
notching material.

Unit: The term used to identify the complete self-contained
punching device.
