At Illinois Broaching Co., Inc. we specialize in high speed broaching, our advanced capabilities allow us to produce extremely tight tolerance broached products. The project highlighted here exemplifies this capability. A customer in the medical industry contracted us to fabricate two sets of custom broach tooling for use in the manufacture of hydraulic systems for hospital beds. This project required tolerances of +/- 0.0003". Working with high speed steel, which would enable the customer to achieve fast cutting rates, our technicians rough milled the pieces, surface ground them to the exact dimensional requirements, then sharpened the teeth with exacting skill and precision. All work pieces were heat treated, and a TiN (titanium nitride) coating applied to promote edge retention and corrosion resistance. The insert broaches, which measured 13-29" x 0.3750" x 1.40", and the 2.5" x 0.750" slab broaches were dimensionally inspected and functionally tested to ensure the customer specifications were met.

Our many years of experience and the superior skills of our craftsmen brought this project to a perfect conclusion. To learn more about this project, our custom broach manufacturing process, contact us today.
