Hi-TECH 750 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, and smooth cutting even at the maximum machining diameter.
High precision is ensured 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.
