About Hokus Profilschleifen
Hokus Profilschleifen is a specialized contract manufacturer for high-precision CNC profile grinding based in Massenbachhausen, Baden-Württemberg. The focus is on machining demanding tool components for injection mold making, such as slides, inserts and cores, with manufacturing accuracies in the micrometer range down to ±0.001 mm. Complex profile geometries are machined in hardened tool steels (including 1.2343), high-alloy steels and special alloys. In addition to new production of prototypes and small series, the range of services includes correction and rescue of high-value components by regrinding, project-based production of complete tool sets, special clamping jaws, roller jaws, machine knives up to 550 mm, as well as grinding of straight gear teeth and flat surfaces. Customers come from injection mold making, medical technology, the defense industry, automotive and precision machine building. Via the express service GrindXpress, short-notice repairs are offered including laser welding and hard chrome plating with regrinding, measurement reports and express shipping.
