Applications

Grinding of Pin Journals

 

´╗┐

WINTER: Innovation - Precision - Performance - Quality

When operating crankshafts, they have to resist high specific demands with regard to the fatigue strength with more than 109 alternations of load.

Grinding is the only economical way to achieve the compliance of requested parameters like surface quality, cylindricity, straightness, conicity etc.

Objective To improve the dressing cycle
 
Machine

Landis Twin-Pin Orbital 

Coolant

Emulsion

Component
