Milling technology
Milling is the term used for machining metals with the help of a milling tool. The work piece is given its desired form by cutting off surplus material in the form of chips. The process is also known as “chipping” or “machining”, which is synonymous with “forming”.
Milling is carried out on our own central machining installations where CNC milling is done in three-axis-technology. The process is monitored via the machine control systems either individually or simultaneously with feed mechanisms.
CNC technology makes it possible to form even the most complex 3D contours.
Our machining centres produce high-precision parts with an accuracy of 1/100 millimetres; this process also allows us to incorporate internal threading into parts.
