The Johnford ST-40HB is a heavy-duty, high-precision CNC turning center built for industries that need large lathes for big parts. This slant-bed machine is available in bed lengths of as much as 240" and with spindle holes up to 21".

Built with the classic style, the 60-degree slant bed is a torque-tube design. The torque tube or hole cast through the center of the slant bed, provides an rigid bed and excellent heat dissipation, the company says.

The turning center has a 35-hp high-torque spindle motor and standard four-speed gearbox, which delivers high torque at low rpm. An optional 50-hp spindle motor is available for heavy-duty machining on large diameters. The precision spindle structure is mounted using precision double row roller bearings in conjunction with angular contact ball bearings for high rigidity and accuracy. The spindle quill inner and outer linings are precision ground for fit with the spindle.
