1 Usage of the machine tool

This machine is mainly used to handle some medium-sized and miniative metal components with the features of high stiffness, precision and complexity such as sintered-carbide and chilled steel. It can be widely used in the tools of industries like instrument and automotive, laboratory shops as well as manufacturing all varieties of hard-metal components of former blocks, explorator, module boards sintered-carbide.
