Niigata Machine Techno USA has released the HN80E-5X 5-axis horizontal machining centre, the largest of its heavy-duty HN-5X series.
The machine has 49.2 in. of travel in the X axis, 48.4 in. in Y, and 47.2 in. in Z. It allows a maximum workpiece diameter of 49.2 in., height of 39.4 in., and weight of 3,300 lbs.
A 5-axis compensation function helps ensure high accuracy over extended periods. Five-face machining means a reduced number of setups and simplified fixtures for reduced changeover time. For additional efficiency, the tool magazine is driven by a servomotor for fast and reliable indexing, the manufacturer says.
Both ends of the 5-axis trunnion table are supported by the high-load-type roller BRG and a double-lead worm gear system for low-frequency machining. The HMC is equipped with an optical scale feedback system (on X, Y, Z axes) and an inductive scale feedback system (on A and B axes) as standard.
A high-torque, heavy-duty spindle complements the rigid machine frame. The spindle head stock consists of mono-cast castings for more powerful milling and greater accuracy than bolt-together-type spindle heads.
