Niigata Machine Techno USA has introduced the HN800-V horizontal machining center.

The HN800-V is built with rigidity and accuracy for precise contour machining and boring of components with critical tolerances. Niigata says the HN800-V is the world’s first machining center to feature hardened and ground inverted V-shaped slideways. The machining center achieves volumetric accuracy of .00005” per foot.

The V-shaped slideway system converts the weight of the column unit into restraining force on the sliding unit. This restraining force enhances stability, with long-term axis straightness of motion that eliminates pitch and yaw motion. The combination of hand-scraped slideways and hardening-processed slide guides maximize the machine’s durability.

The V-shaped slideways, consisting of anti-abrasion material, also contribute to the high-speed performance of the machine, reaching rapid traverse of 50m/min (1968 ipm).

The HN800-V’s pallet clamping system utilizes a stable clamper plate to ensure optimum down force and increased clamping forces of the pallet during extreme cutting conditions. Jets of air discharge from the tapered cones when the pallet is changed to ensure proper clamping and to cleanse seating surfaces.

The HN800-V offers 1530mm (60.2") X-axis travels, 1230mm (48.4") Y-axis travels, 1020mm (40.2") Z-axis travels, and a B-axis rotary angle of 360,000 positions. Maximum workpiece swing diameter is 1750mm (68.9"). Maximum workpiece height is 1400mm (55.1”).
