JUCAM

Grinding camshafts with JUCAM

With its JUCAM CBN non-circular grinding machines, JUNKER offers a multi-purpose solution for the complete machining of camshafts. And the JUCAM is also able to grind single cams. The type range covers all cam profiles:

Cylindrical
Concave/convex
With/without chamfers
With/without radius
With tangent
Polygon/elliptical

Depending on the machining method and the required yield, platforms and grinding spindle head versions are individually configured and installed for the various JUCAM types.

Pre- and finish grinding in one clamping

JUCAM non-cylindrical grinding machines mean: grinding cams, bearings, ends, thrust bearing shoulders and camshaft adjustment elements in one clamping. The use of CBN grinding wheels permits both pre-grinding and precise finish grinding. Besides the automotive industry, these machines are also used in the textile and pump sector and for making cutting tools for deep-hole drills
