Crankshafts | CrankStar

Microfinish / Superfinish of crankshafts with the Thielenhaus CrankStar

The CrankStar surface precision machining unit is the solution to fulfilling the requirements set today by engine manufacturers: reduced friction coefficients, the greatest level of durability and the lowest possible unit costs.

MICROFINISH / SUPERFINISH OF CRANKSHAFTS WITH THE THIELENHAUS CRANKSTAR

The average vehicle uses up to 340 litres of fuel per year simply in order to overcome the internal friction in a combustion engine. The requirements placed on the installation of crankshafts are increasing in line with demands for lower consumption, higher performance and sustainability. 

Compact dimensions as well as precision bearings and sealing seats are, in this regard, important contributors to environmental balance, performance and longevity. The Thielenhaus CrankStar precision crankshaft machining unit is the perfect solution for the challenges experienced by today’s engine manufacturers.

Microfinish / Superfinish machining improves the surface, contact ratio and dimensional tolerance of components. Optionally, the front pin can be machined and the flange bores deburred.
