FAQ

Frequently Asked Questions

What is a surface broach?

A surface broach is a cutting tool used to machine external (outside) surfaces of a workpiece in a single linear stroke. Unlike internal broaches that cut bores, surface broaches machine flat, stepped, or complex formed profiles on the outside of a component. They are used for high-volume production where consistent surface finish and profile accuracy are critical.

What profiles can SK Broach manufacture for surface broaches?

We manufacture flat, stepped, dovetail, fir-tree, T-slot, and custom formed profile surface broaches. Complex profiles (such as turbine blade root fir-tree profiles) are manufactured to customer drawings in DXF, PDF, or STEP format.

What industries use surface broaches?

Surface broaches are used in turbine and power generation (blade root slots), automotive (engine block faces, transmission housings), aerospace (structural component profiles), railway (bogie frame and coupling faces), defence and ordnance, and heavy engineering.

What is the maximum length of surface broach you can manufacture?

SK Broach manufactures surface broaches up to 1500mm in length and 200mm in width. Longer broaches are available on request — contact us with your requirement.

What surface finish can surface broaches achieve?

SK Broach surface broaches can achieve Ra 0.4 μm in optimal conditions. Typical production values are Ra 0.4–0.8 μm. The exact finish depends on workpiece material, cutting speed, and lubrication.
