Broaching is used for precision machining to produce products with unique shapes. Commonly broached surfaces include circular and non-circular holes, keyways, straight sided, involute and external splines. At HM Manufacturing, vertical broaching, shaper cutting and keyseating are the services used to cut straight-sided and involute internal shapes, keyways and forms.
Internal involute splines

Stroke Range 50 - 1300 SPM
Max Diameter (External) 508 mm
Max Diameter (Internal) 508 mm
Max Helix Angle 45 Degrees
Keyseating is a machining process in which internal shapes and forms are cut using a single-point cutting tool. Similar to keyseating, shaper cutting also uses a single-point cutting tool. The difference between keyseating and shaper cutting would be that a keyseater enters through the bottom of the work piece and cuts by using the down stroke, pulling material away from it, only to produce a keyway. A vertical shaper cutter enters through the top of the part and cuts using the down stroke, by pushing material away from the piece to produce a desired internal or external straight sided design. HM offers a variety of broaching services in many different sizes and styles that are sure to suit any broaching need. Our CNC shaper cutters and CNC vertical broaching machines are typically used for larger production cycles, offering versatility in size and irregular shapes, while maintaining accuracy, repetitive size control and quick production rates. For shorter runs, HM provides high quality keyseating services that are primarily used to cut internal keyways and straight edged shapes.
