Johnford ST-80CX + Index Chuck Slant Bed Lathe

The Johnford ST-80CX is a heavy duty, high precision CNC lathe. Capacities include 47.2" swing over the bed, 39.4" turning diameter, 39.4" swing over carriage, 20.47" X axis travel, 78.7" Z axis travel, and 88.5" centers. Cast from Meehanite iron. Full advantage of the 50HP (60HP optional) spindle motor and 4 speed gear box is taken by the massive one piece, 60 degree slant bed design. Built in 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 extremely rigid bed and excellent heat dissipation. The square box ways provide the rigidity for heavy duty turning. Hand scraped Turcite - B applied to all mating sliding surfaces ensures high rapid traverse rates and accurate positioning. To ensure precision and thermal stability the headstock, tailstock, and saddle are all mounted on the same plane at a 60 degree angle. The coolant tank is separate from the machine base to prevent heat transfer from the coolant to the machine casting which ensures precision and promotes easy clean out and maintenance. To further ensure accuracy and precision, the ballscrews are double nut type and pretensioned to eliminate thermal growth.

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, thus ensuring extreme concentricity and accuracy. The spindle is driven by a 50HP high torque motor which provides plenty of power. For applications requiring high torque at low RPM’s, a four speed gear box is standard. A 60HP Spindle Motor is available for high power cutting.

A 12 station bi-directional turret or optional BMT servo live turret provides .5 second indexing as well as coolant through the tool holders. A full C axis with live tools is available for applications requiring milling operations. Fanuc controls are standard for performance and reliability.
