Kesel Rack milling machine RM

The Kesel RM machine takes rack milling to a new dimension.

Based on the design of the very successful Kesel RMS and RMX rack milling machines, the RM sets new standards in its class. The cutting area for straight tooth profiles as well as helical tooth profiles has been increased for more productivity. Its FEA analysed structure is engineered and built for much higher rigidity values compared to any other machine of its size. The RM scores remarkably higher performance results and can be used for rack production of up to module 20 or 32 depending on the milling head. Higher milling capacity and extensive optional features in combination with superior quality are the main benefits. The RM is equipped with a Siemens SINUMERIK 840D sl control.
Extensive optional features make this machine a complete milling centre meeting all customer requirements.
