The HN80E-5X 5-axis horizontal machining center (HMC) uses the solid cast-iron X and Z base of a larger, heavy-duty HMC, providing rigidity, stability, and accuracy. Simultaneous 5-axis machining improves cycle times and machines surfaces of complicated and 3D curved components. A 5-axis compensation function ensures high accuracy throughout extended periods. Using 5-face machining decreases the number of setups and simplifies fixtures for reduced changeover times. A servo motor drives the tool magazine for fast, reliable indexing.

Guideways combine hardened and ground hand-scraped turcite for stability and vibration-damping characteristics and long life. The rectangular guideways’ cross section is thick and wide for maximum machine rigidity. A bifurcated bell-shaped column further contributes to rigidity and metal-cutting efficiency.

Both ends of the HMC support heavy-duty 5-axis trunnion tables, using high-load-type rollers and a double-lead worm gear system for low frequency machining. An optical scale feedback system (X-, Y-, Z-axes) and an inductive scale feedback system (A-, B- axes) improve accuracy.

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 spindle heads.
