CNC 5 Bed Way Heavy Duty Extra Long Turning Centers
Product Highlights
The Kent CNC LL Series Extra Long 5 Bed Way Heavy Duty Turning Centers allow for seamless turning from tip to tip with its 5 individual bed way structure. The 5 bed way design keeps the carriage, tailstock and steady rest on their own ways. This special high-low bed ways design retains the rigidity of a flat bed lathe while also having the advantages of slant bed lathes. The LL Series Extra Long 5 Bed Way Heavy Duty Turning Center Series features up to 53 feet (16,000 mm) of distance between centers, 16 inches in spindle bore diameter, and over 22,000 lbs of turning capacity.
Turret, Steady Rest, and Carriage
The high concentricity hydraulic steady rest allows automatic adjustments for clamping different diameter work pieces. All clamping/unclamping can be controlled by M code. On the other hand, the manual steady rest is equipped with a 3-point heavy duty needle roller bearing. The tool can also pass the steady rest without interference. Lastly,Our box type carriage and cross slide do not interfere with the steady rest. In addition, Turcite B lining is applied on cross slide and carriage to reduce friction.
Tailstock
The tailstock is equipped with high-precision rotary mandrel which provides maximum rigidity and high load capacity. In addition, the electric and manual quill movement allows for easy quill positioning.
