Hi-TECH 550BB

Big Bore Heavy Duty Horizontal Turning Center

Hi-TECH 550BB is a heavy-duty horizontal turning center optimized for large long shafts and pipe machining by applying a big bore.

Hi-TECH 550BB 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.
