| The structure characteristics of CNC lathe | Compared with the traditional lathe, numerical control lathe structure has the following features:
(1) because of the CNC lathe knife two direction respectively by two servo motor drive, so it transmission chain of short. Don't use wheels, light transmission parts, use as its servo motor driven directly with the ball screw connection frame movement. Servo motor ball screw can also use synchronized belt between vice or gear pair coupling.
(2) multi-function CNC lathe spindle is used dc or ac drive control unit and press control instructions for spindle speed stepless, don't use between spindle speed to multistage gear pair. For now, general speed range expanded through level, in order to realize the gear pair section stepless speed, even so, the structure has been much simpler than traditional lathe. CNC lathe is another structure stiffness big, it is in order to control system with high, in order to adapt to match the control precision machining.
(3) nc lathe third structure characteristics is light drag. Turret mobile generally USES ball screw assembly. The ball screw pair of CNC lathe is one of the key mechanical components, ball screw rolling bearings of installation ends, it is the special uranium pile the pressure Angle than the commonly used to thrust ball bearing much bigger cars. This special bearings, is optional matched installation, the best in bearing factory is in pairs.
(4) to drag deft, CNC lathes are full of lubrication oil mist, most adopts the automatic lubrication.
(5) because of the high price of CNC, the control system of life is long, so the sliding guide CNC lathe also require good abrasion resistance. With commonly used CNC lathe, this machine precision steel rail time is long, can prolong its service life.
(6) nc lathe machining cooling fully, also has the characteristics such as a strict protection and automatic operation are generally in the closed or semi-closed state.
(7) nc lathe are equipped with automatic scraps discharge device.
