Among the broaching services we perform are continuous chain broaching; horizontal and vertical broaching; surface broaching; internal and external broaching; specialty broaching—blind-hole, pot, spiral and straddle broaching. To cut a form or create an internal shape, we are the company to rely on.
Superior production keyway broaching services. Virtually any bore and keyway combination is possible with our keyseater. Shallow keyways, slightly deeper keyways, special widths and keyways with a radius on the corners to prevent stress cracks. Broaching thousands of internal keyways each week!
Our company was founded in 1919 by the father of modern broaching. Using his broaching techniques today, our development of broaching applications equals a modern facility with expert craftsmen at our broaching job shop. We offer keyway broaching, production broaching, rifling, spline cutting & more.
Broach cutting tools, broaching machines and production broaching services are our business. Our capacities for our broaching services include 180” to 15” stroke. The services we perform include blind-hole broaching, internal broaching, pot broaching, surface broaching and turbine disk broaching.
Since our start in 1962, we have grown in our capabilities. One of the many services we are known for is our broaching—large or small production runs. Our services in broaching include keyways, involute splines, serration broaching, blind spline broaching, flats, forms, hex and rectangle.
Spline shafts contain a series of ridges on a driveshaft that even out the rotation speed of the companion piece. The spline shaft’s number of teeth and preferred pitch diameter determine the pitch of a spline gear.
Spline shafts can be made from a variety of materials, including aluminum, cast iron, steel, stainless steel, and brass. Some spline shafts now incorporate plastic along with the traditional metal composition of the gear.
The grooves in spline shafts are created by broaching machines. Broaches, or metal tools with a row of successively larger teeth, are used to cut various materials like wood, metal, and plastic. They can be used to cut holes or to alter the surface of a product.
In the manufacture of spline shafts, broaches are used on the material’s surface to cut the furrows along the length of the shaft. As the spline rotates, these grooves interlock with the matching grooves in the mating piece; this connection enables a spline gear to transfer torque.
