Kopp spindle and motor spindle repair
Brochexpress is an independent workshop specialising in the repair, maintenance and diagnostics of Kopp spindles and motor spindles — the German specialist in non-cylindrical grinding of cams and camshafts, part of the grinding division of the EMAG group.
Kopp, German specialist in non-cylindrical grinding of cams and camshafts
TLDR: Kopp is the technology specialist for non-cylindrical camshaft grinding within the grinding division of the EMAG group, alongside Reinecker (internal/external grinding of chucked parts) and Karstens (external grinding of shaft parts), with the SN range intended for the production of camshafts for heavy truck engines, motorcycles, injection pumps and many other applications.
Within the grinding division of the EMAG group, Kopp is the technology specialist for non-cylindrical camshaft grinding, know-how brought together under one roof with that of Reinecker and Karstens since the merger of these three historic manufacturers. Manufacturers in the camshaft market segment rely essentially on the group's complete process chain solutions, with the Kopp SN range offered as a highly flexible optimal solution, whether for camshafts for motorcycles, light vehicles, heavy trucks or even very large diesel engines. Typical application examples include the production of camshafts for heavy truck and motorcycle engines, injection pumps, eccentric shafts, external polygons, and external contours for textile and packaging machinery.
A range of modular wheel spindles for cams with cylindrical or tapered tracks
TLDR: Kopp camshaft grinding machines use different sizes of wheel spindle within a modular system, with an X axis fitted with a hydrostatic leadscrew and guideway delivering exemplary grinding accuracy, able to grind cams with cylindrical or tapered tracks, with concave radii or chamfers.
The modular system dedicated to equipping Kopp camshaft grinding machines comprises different sizes of wheel spindle, combined with in-process and post-process measuring systems, dressing devices for CBN and corundum wheels, cut detection during grinding and dressing, drive dogs and clamping chucks in several sizes. The X axis, fitted with a hydrostatic leadscrew and guideway, delivers exemplary grinding accuracy, while the cross-table concept minimises the overall footprint of the machine. This architecture makes it possible to grind cams with cylindrical or tapered tracks, cams with concave radii or cams with chamfers, flexibility sought after to cover the diversity of camshaft geometries encountered in automotive production.
