45"X80" ACRA MODEL CL-68A HOLLOW SPINDLE CNC FLAT BED LATHE WITH FANUC OITD CONTROLLER

45"X80" ACRA MODEL CL-68A HOLLOW SPINDLE CNC FLAT BED LATHE WITH FANUC OITD CONTROLLER

PENDANT TYPE OPERATION BOX:
• The Pendant type operation box can be moved to an appropriate operation position and can be swiveled for increasing convenience in operation.
• The Flat Bed machine structure presents perfect rigidity and without structural deformation.
• The Cross-Slide moves on the dovetailed slide ways for high straightness accuracy.
• The Tailstock can be mounted with a chuck to achieve a sub-spindle function.

HYDRAULIC SYSTEM:
• The Hydraulic System consists of high-quality components with outstanding features for stable performance, low thermal growth, low noise and suitable for long time continuous operation.
• Powerful Spindle motor drive makes the machine ideal for heavy cutting.
• V8 Hydraulic turret is standard.
• Equipped with Double door.

V8 HYDRAULIC TURRET:
• V8 Hydraulic Turret is a standard accessory.
• Tool selection method is bi-directional, random tool selection.

HEADSTOCK:
• The Headstock is a highly rig id structure, which offers superb stability in heavy cutting.
• All gears in the Headstock employ high precision Japan JIS class 1 gears, assuring smooth with low noise.
• Headstock lubrication is a forced lubrication system operated by a pump.

SPINDLE:
• Spindle Bore: 7.1”.
• The Spindle associate with P-Class Taper roller bearing that presents outstanding stability in heavy cutting.

CARRIAGE AND CROSS SLIDE:
• X, Z- Axis are driven by individual servo motor and transmitted through high precision ball screws, that provide extremely smooth feed and high positioning accuracy.
• The Cross-Slide moves on dovetail slide ways. Sliding surfaces are hardened and precision ground as well as providing outstanding wear-resistance.

TAILSTOCK WITH SUB-SPINDLE FUNCTION:
• The Tailstock quill movement is driven by hydraulic power or manual for fast and convenient working loading and unloading.
• The Tailstock Quill can be mounted with a chuck with sub-spindle function.
• The Quill is a MT#5 dead center.
• 5.9” Quill Diameter makes it suitable to hold a large workpiece.
