OKUMA LH55-N CNC LATHE

Technical Description

This heavy-duty Okuma turning center features a 24-inch maximum swing over saddle with 120 inches of available machining length, making it suitable for large-diameter, long-length workpiece production. The machine is equipped with a dual 2-axis configuration controlled by the proven Okuma OSP-700 CNC control system. The dual V8 block-style turret provides 16 tool positions total, enabling efficient multi-operation processing with minimal setup changes. The X-axis offers 26.57 inches of travel with a rapid feedrate of 197 ipm, while the Z-axis provides 119.29 inches of longitudinal travel with a rapid feedrate of 394 ipm, facilitating quick approach and retraction cycles. The cutting feedrate capability ranges from 0.0001 to 39.37 inches per minute, allowing precision finishing operations and aggressive roughing passes. Powered by a 50-horsepower spindle motor with an A2-15 nose configuration and 6.89-inch bore diameter, the spindle operates within a 10 to 1,000 rpm range, accommodating diverse material and tool requirements. The hydraulic tailstock accepts MT #6 taper tooling for steady rest and center applications. This substantial machine weighs 28,600 pounds and occupies 127.56 x 204.72 inches of floor space, requiring either 220 or 440-volt electrical service. The combination of rigid construction, extended Z-axis travel, ample tool capacity, and flexible spindle speeds makes this machine ideal for heavy-duty production turning operations involving large components.
