Broaching is the machining process of cutting a shape by moving a broach cutting tool, usually just called a broach, over material such as metals or plastics. The broach's rows of teeth, or chisels, progresively increase in size. Each tooth removes the excess material gradually and the desired shape is complete only after the final broach tooth has passed through the material. The shape found in an internal keyway in a pulley or gear is the most common shape produced by broaching since broaching is the simplest method of cutting internal forms known as splines in gears, sprockets, and hubs. Polygons such as squares are also commonly and easily produced by a broach, especially when a round hole needs to be enlarged into a square or other non-circular shape. Sometimes, broaches are also used to cut external shapes such as slots.

Vertical Dual Ram Broaching
Using a dual ram-broaching machine in which both rams share the same hydraulic, electrical and a lubrication system can increase production. This decreases the cost substantially lower than two machines. Typically one person will operate both rams at the same time. The same heavy-duty designs
that are used on the single ram machine are all applied to the dual ram equipment.

Horizontal Broaching
Horizontal broaching machines offer an advantage for large parts where their size would cause a major cantilever problem for vertical machines. These machines typically do not require a pit or platform. They can be used for both internal and surface application. We offer a full range of tonnage and strokes.
