Super Turning Center Tackles Big Parts, Heavy Duty Turning Perfect for the Oil and Gas Industry


· Big lathe tackles large parts and heavy duty cutting

· Great workhorse for oil-field, energy, and construction equipment industries

· 35 HP spindle and 4-speed gearbox deliver high torque at low RPM

· One-piece, 45° slant bed design provides the rigidity for heavy turning and unparalleled ergonomics

· Torque tube design delivers high rigidity and heat dissipation

Lorain, Ohio - The Johnford SL-800B is a heavy duty, high precision CNC turning center built for industries such as oil-field, energy, and construction equipment - industries that need large lathes for big parts. Absolute Machine Tools, Inc. offers this massive (33,000 lb) 45 degree slant bed machine.

The Johnford SL-800B is a heavy duty, high precision CNC turning center cast from Meehanite iron. The rigid 45° slant bed can easily sustain the standard 35HP spindle motor and 4 speed gear box because the bed is made with a torque tube, or hole, cast through the center of the slant bed providing an extremely rigid bed and excellent heat dissipation. Heavy square box ways provide the necessary rigidity for turning large diameter parts. 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 45° 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 35HP 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 12 station bi-directional hydraulic 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.
