Hard Broaching

Accu-Cut’s diamond precision hard broaching process is one-of-a-kind.

Accu-Cut pre-assembles, qualifies, and can demonstrate proof-of-principle for all tooling at no cost to you.

Hard broaching is most widely used to correct internal spline distortion after heat treat. Our precision broaching process corrects the involute form as well as major and minor diameters, all with a single tool. Manufacturers rely on this technology to eliminate interference caused by heat treat distortion. In addition, our process can handle irregular bores such as D-shaped, double D-shaped, lobed shaped, and other non-circular bores.

Our finish broaching requalifies internal splines to a 5H classification or better.

Accu-Cut’s diamond precision hard broaching process can be used as a stand-alone/external process to requalify and salvage fallout parts; or can be used in-line with your everyday process to ensure geometry to prevent fallout.

Accu-Cut’s precision hard broach turnkey systems feature an intelligent feedback system that automatically optimizes the cycle time by minimizing the time needed to process each individual part, even if part-to-part distortion varies.

Unlike conventional broaching processes, Accu-Cut’s precision broaching process is more affordable, takes up considerably less space, and can handle some of the toughest materials.

Improvements in green-state parts produce greater levels of consistency when heat treated. Accu-Cut’s precision hard broaching process improves green-state consistency and reduces heat treat distortion.
