Specifications

The main transmission of the lathe is driven by vector frequency system and a continuously variable speed range could be obtaine

1. This series of machines have the Conventional type and CNC type. The conventional type is represented as "C51_" the NC-type represented as "CK51_".It is suitable for finely and roughly machining of the internal and external cylindrical surface, inside and outside taper, surfacing, grooving of the ferrous metals, nonferrous metals and some non-metallic materials with high-speed steel ,carbide cutting tools.
2. The main transmission of the vertical lathe is performed by vector inverter system; a continuously variable speed range can be obtained by 2 speed-shifting mechanisms.
3.The worktable spindle is centered by high-precision double-row short cylindrical roller bearings of vvhich the radial clearance is adjustable, the worktable is equipped with constant current hydrostatic guideway, It is thereby able to achieve a high rotary accuracy, Iarge loading and small heat deforrnation.
4.There are two types of rail heads: ln the first type the rail head equipped with pentagonal turret, while the side head With tetragonal turret; in the second type the rail head is equipped tetragonal turret, no side head. All head balancing with hydrostatic tank, horizontal and vertical rapid feed could be a continuously variable speeds though AC servo driving
5.The basic pads of the machine tools are all casted, processed and assembled in house The casting material is high quality cast iron HT250  Which has Clear removed the casting stress thoroughIy by annealing process and vibratory process. All the guideways Of the bed and column and beam have been supersonic frequency quenched.
6.Digital control and digital display cold be equipped according to the request of customers.
