Jerpbak-Bayless’ unique capabilities allow us to cut involute and straight-sided splines for any high torque application. We produce both industry standard DIN, SAE, ISO-14 and ANSI B92.1 as well as custom spline profiles. Additionally, we can provide Internal spline shaping and cutting, blind and through. Jerpbak-Bayless can cut the spline profile you require on big or small parts.

Deep Hole Machining

Many of the parts we supply to our heavy industry customers require highly accurate deep hole features. With our CNC gun drilling capabilities, we machine nearly any size or shape deep hole part configuration. From simple rough-drilled to drilled and finish-honed, we hold the tight finishes and tolerances as needed. Machining straight, tapered, stepped, threaded or grooved deep holes in shafts of all sizes is one of our specialties.

The OD grinding machines at Jerpbak-Bayless hold the tightest tolerances on a variety of parts. Any of the parts we machine can be ground in-house to improve tolerances and finishes, reducing the reliance on outside vendor operations. Our OD grinding centers can fit parts of a variety of sizes up to 233” in length.
