multidec^®-BROACH

Polygonal punching is a chip-removing procedure for manufacturing of inside profiles in holes which are usually not continuous. During this procedure, the tool is pushed into a hole in several so-called strokes, and the outline of the broaching tool is introduced into the workpiece. We can supply square, hexagonal and TORX broaching tools made from carbide from our standard product range. We can also manufacture customised shapes and intermediate sizes on request. Advantages: • Short machining times • Complex geometries with sharp edges are possible • Full profile tools reduce the number of strokes • Reliable process with long tool life
