VT-550 provides a rigid and stable heavy duty cutting based on a highly rigid box-way feed structure designed with an air-floating system and bed structure while maintains high precision even during long-term processing by minimizing thermal displacement
Hwacheon software installed on the machine improves productivity and precision, provides better machining quality compared to existing machines
The spindle position can be selected in two types, left and right, and with a wide range of machine types and compact design, such as using two machines with one control panel, it is particularly capable of processing and automation of brake discs, drums, hubs and valves.
