6 spindle turning machines with a bar capacity from 6 – 35 mm
Centerless grinding machines. The last machine in the grinding line has a 100 % measurement.
Testing equipment for roughness, roundness, cylindricity and profile
Automatic gas carburizing heat treatment or themper hardening with additional gas analyzer and automatic testing of the effective hardening depth.
During the heat treatment the parts can - materialrealted - grow or shrink to a minor extent. Parts with very small tolerances - mostly the length - will not meet high demaned cpk values. Therefor after hardening and tempering they are 100% fully automatic tested on diameter and lenght.
Since august 2013, we have a new 6-spindle lathe GMC-20 made by Gildemeister in use. On this machine piston pins an crank pins with large production lots are produced. The maschine is equipped with bar loading magazine and inner cooling and we also use it to manufacture piston pins with an conical bore.
