The workpieces processed by a knee type mill are restricted due to the stud frame's restricted dimensions and carrying capacity; it is only suitable for small and medium-sized workpieces. Knee type milling machines mainly only work with one milling tool. In order to undertake a further processing step, the work tool needs to be manually switched after every cycle. These factors restrict the efficiency of a knee type milling machine. However, they are still commonly used as a component for CNC machines. One big advantage is that they are very stable.
KLOPP Knee Type Milling Machine in use
Contrary to the complex 5-axis mechanics of a modern CNC-machine, the milling head only moves in one direction meaning that they are not prone to accidents. The knee type milling machine can be used for preparatory clearing tasks. The less restrictive pieces of the workpiece can then be processed using CNC-machines. Therefore, there are still manufacturers of knee type milling machines, like UNITECH.
