Custom Keyways / Broaching Services
As a provider of keyway and broaching services, Precision Gears, Inc. offers an efficient way to machine keyways & internal splines. Precision is of the utmost importance in shaping and broaching operations, and our facility is well-equipped to handle these requirements. We offer two related services: shaping and broaching, each with similar properties but slightly different capacities. For shaping, we can cut a width from 1/16" to 3/8", with a depth of 0.032" to 0.5" and a length up to 6". If the customer chooses our broaching service, we offer a width capacity from 0.063" up to 1", with a depth from 0.031" to 0.5" and a maximum length of 5". Precision Gears, Inc. also stocks a large variety of broach bars for your internal spline needs.
We can work with a wide variety of materials: metals including alloy steel, aluminum, carbon steel and ductile iron, as well as plastics, phenolics, and Delrin. Our customers come from all industries: machinery, medical, optical, packaging, construction, and many more, and we can produce in short or long runs. Contact Precision Gears for more information on our broaching and shaping services.
