Ohio Broach produced this wrench jaw using a 15-ton broaching machine.

The Ohio Broach & Machine Company offers expert production broaching services. The company is known as the total broaching source, with more than 55 years of experience performing machine and tool design, manufacturing, repairs, rebuilds and more. This experience enables the company to provide ideal solutions to its customers’ production broaching challenges. One example is a customer that required a better way to manufacture ready-to-assemble wrench jaws.  

The challenge

A customer came to The Ohio Broach & Machine Company because its existing tooling process was under-performing. The customer had been using a small broaching machine with approximately 24 inches of stroke. The deep slot in the wrench jaw was broached in multiple passes, which resulted in problems with tooling breakage and difficulty keeping up with demand. 

To solve this problem, design engineers at Ohio Broach created tools that could broach the slot in a single pass. 

Wrench jaw broaching process 

The process was performed on a 15-ton, 90-inch stroke broaching machine. The wrench jaw’s deep slot, rounded slot and serrated tooth form were all broached on the same machine in progressive operations. The machine fixture was configured as three stations, and an operator transferred parts between them. This process is highly efficient, as a completely broached part is removed from the fixture at every stroke of the machine. Then the part is loaded into an automated drilling station. Lastly, the wrench jaw is deburred, heat treated, black oxidized and shipped to the customer.
