Nc machine tools and the comparison of ordinary machine tools
1. Precision of the upper hand
Ordinary lathe by gear quiet every screw and nut. As the gap between vice, plus manual manipulation is not correct, so the repeat precision is low. Ordinary lathe measurement should stop back working when the work measurement, the measurement deviation is larger.
Numerical control lathe on drive motor mobilize the ball screw transmission. Ball screw course pre-stretching placed after the amount of interference, the transmission zero clearance, important on machine own pace and guaranteeing precision. During the course of processing can be held by the encoder position measurement, can compensate for tool wear and other reasons because of the deviation. With processing is good quality, stable precision.
2. Mass production to obey the upper hand
A ordinary lathe need a skillful manipulation of workers. Because of using manual three jaw chuck and the measurement must stop back when workers work measurement, processing and obedience is low.
In batch production, the use of hydraulic chuck or collet chuck clamping workpiece, a don't understand any skill workers can operate at least two CNC lathes. In the production of obedience is the use of ordinary lathe more than four times. Once the figure environment Clinton about mind manipulation workers did not meet, the product rejection rate will rise sharply. CNC lathe is guaranteeing the machining accuracy by setting equipment deployment, manipulation of workers was only have the effect of unloading workpieces and switch, very little man-made influence, to product pass rate is higher than force.
3. Procurement capital high
The price of the same specifications of the nc lathe is 1 of ordinary lathe. More than 5 times. But taking human as the numerical control system of the cost of land, capital on nc lathe disadvantages will be more and more small. Single processing capital now higher than ordinary lathe of numerical control lathe, piece now processing the production of capital is higher when the indisputable. But if the course innovation, numerical control lathe on single production capital and obey will also better than ordinary lathe.
