Horizontal lathes
HL2660/800 engine lathes

1. Gear-headed with high spindle speed for precision turning; 

2. Very rigid machine bed is of double-wall ribbed structure and features superb rigidity; 

3. Bed ways ultrasonic frequency quenched and precision ground to ensure a long accurate service life;

4. Removable gap section is provided for swing of workpieces with large diameters;

5. Gears in headstock and feed gearbox hardened and precision ground for low noise in running;

6. Spindle mounted on high-precision tapered roller bearings and high-precision angular contact ball bearings for high-speed accurate revolutions;

7. Automatic feeds and threading operations are fully interlocked;

8. Maximum accuracy and quiet operation even at high speed; 

9. High machining capacity with 7.5 KW or 11 KW main motor; 

10. Large spindle bore diameter as 105mm for machining of long bars; 

11. Feed gearbox well sealed to eliminate leakage;

12. The machine can turn about 200 kinds of metric threads, inch threads, whitworth threads, diametral pitch threads and module threads;

13. Tailstock locked by thread and cam lock;

14. Tailstock is adjustable in the cross direction for turning tapers on workpieces;

15. Electric system is reliable and safe. The main power supply is shut off automatically when the electricity cabinet is opened or the change gearboxs hood is opened;
