Custom Hob Arbor – S. Carolina

At Toolcraft, LLC, our highly experienced machinists use the latest manufacturing and inspection technology to ensure our customers receive precision quality tools that add measurable value to processes that require high accuracy.

We manufactured the custom hob arbor shown here from 8620 steel for use as a toolholder on a gear hobbing machine. Primary operations consisted of CNC turning the tapered diameters and milling the complex features of this 4.0″ in diameter x 18.0″ in length workpiece. After case hardening to RC 58-60, we executed a straightening process to correct any heat-induced warpage or deformation. Our machinists have the discipline and experience to manage the rigors of close tolerance work and ground the arbor to tolerances of +/-.0002″.
