Gear-headed with high spindle speed for precision turning;
Wide very rigid machine bed is of double-wall ribbed structure and features superb rigidity;
Bed ways ultrasonic frequency quenched to hardness HRC 52 and precision ground to ensure a long accurate service life;
Removable gap section is provided for swing of workpieces with large diameters;
Gears in headstock and feed gearbox hardened and precision ground for low noise in running;
Three-point-mounting spindle mounted on high-precision tapered roller bearings and high-precision angular contact ball bearings for high-speed accurate revolutions;
Automatic feeds and threading operations are fully interlocked;
Maximum accuracy and quiet operation even at high speed;
High machining capacity with high power main motor;
Large spindle bore diameter for machining of long bars;
Feed gearbox well sealed to eliminate leakage;
The machine can turn enough kinds of metric threads, inch threads, whitworth threads, diametral pitch threads and module threads;
Tailstock locked by thread and cam lock;
Tailstock is adjustable in the cross direction for turning tapers on workpieces;
Electric system is reliable and safe. The main power supply is shut off automatically when the electricity cabinet is opened or the change gearbox's hood is opened;
Longitudinal mechanical stop provides quick and effective start or stop during the operation of the machine, thus decreases the standby time and improves the productivity;
Digital readout (2-Axis) is mounted on this machine;
Taper turning attachment is supplied with this machine;
One-piece casting base provides enhanced rigidity for the whole machine;
Machine color is coated at buyer option.
