Triumph uses lean selection cam high-speed grinding machines developed by JUNKER for grinding its camshafts for superior performance
Camshafts play a key role for the engine and their high quality can make a significant difference in a vehicle performance. Triumph uses four Lean Selection cam machines from JUNKER to grind its camshafts that offer flexibility among cylindrical and non-cylindrical grinding. Cylindrical, convex, concave, polygonal or elliptical workpiece geometries can be ground – with chamfers or radii if needed, claims the company.
It is particularly important for the motorcycle manufacturer that cams and bearings can be ground on the same machine in a single clamping set-up. Technical improvements to components mean that the grinding process needs to be constantly re-adjusted. The Lean Selection cam makes it quick and easy to produce this wide range of high-quality parts. Small series require rapid machine changeover, which is where the machine’s easy operation proves itself. Due to a flange positioned in the centre of the workpiece, the company came up with the solution with JUNKER to ensure that the spindle housing did not collide with the workpiece.
In addition to its headquarters in England, Triumph also has production sites in Chonburi, Thailand. The motorcycle manufacturer produces around 56,000 bikes each year at both locations.
