Precision processing
The right process for every challenge.
Contour grinding
KERN-LIEBERS specializes in the precision grinding of pump, injector and other precision parts – typical tolerances for thickness and flatness are less than one micron at an average surface roughness of less than ra < 0,1.
The ground parts can be biconcave (concave on both sides), with a flatness tolerance of 1.5 to 2.5 microns, for example to ensure tightness in injectors, allowing reliable sealing against high pressure with a sealing length of less than 1 mm.
