Custom Broach Tooling for Gear Manufacturing

Custom Broach Tooling – S. Carolina

For over half a century at Toolcraft, LLC the expert craftsmanship of our toolmakers has been elevating the industry standard for precision broach tooling. We fabricated the tool set highlighted here for a customer in the gear manufacturing industry who knew they could rely on us for a superior product and great service.

Used to manufacture large gears, this set of tooling included a broach horn with dimensions of 6.0″ in diameter x 16.0″ in length, which we fabricated from 8620 steel to provide high surface wear resistance. We fabricated the two 1.5″ wide x 18.0″ long shims, one measuring 0.250″ in thickness, the other 0.187″ from tough A2 steel for maximum dimensional stability during heat treatment.

Capabilities Applied/Processes

Primary operations consisted of CNC turning and milling to create the part features and geometries. The parts were then case hardened to RC 58-60. The talents of our journeymen grinders were required to hold these components to within tight +/-.0002″ dimensional tolerances. 

Delivery/Turnaround Time

We delivered the tooling to the customer within a 4 week timeframe, where it is now helping them yield high production rates and  manufacture the best possible product. Our commitment to excellence is why we achieved a long standing relationship with this client and continue to do many projects for them.
