You Ji AH Series Horizontal Slant Bed Lathes for Oil & Gas Industries

The You Ji AH Series horizontal slant bed lathes are engineered for heavy-duty turning applications, particularly in the oil and gas sector. These machines feature a robust 45° slant bed and a 55° inclined cross slide, enhancing structural rigidity and improving operator accessibility. Built for strength and long-term reliability, the AH Series draws design inspiration from the iconic Mori Seiki lathes of the 1980s.

Each of the two AH models is equipped with a powerful 60 HP spindle supported by dual double-row roller bearings for superior radial load handling and angular contact bearings for axial stability. This configuration delivers impressive torque — up to 3,154 lbs./ft. at just 100 RPM. A 3-speed geared head, paired with an oil chiller unit, ensures consistent thermal stability during prolonged operation. Additionally, the coolant tank is isolated from the machine base, preventing heat transfer to the casting and simplifying cleaning and maintenance.

The 55° inclined cross slides not only enhance operator access but also increase the mass and rigidity of the saddle assembly. Both X and Z axes use widely spaced box ways with hand-scraped mating surfaces coated with Turcite-B for low-friction, long-life performance. Large 2.5″ (63.5 mm) diameter precision ballscrews in the Z-axis, driven by high-torque Fanuc servo motors, provide exceptional thrust for demanding turning, boring, and drilling tasks.

A heavy-duty 12-station turret, hydraulically actuated and clamped, includes a 6.5″ (165 mm) thick tool disk capable of holding 1.25″ (31.75 mm) square-shank turning tools and boring bars up to 3″ (76.2 mm) in diameter.
