The difference between CNC lathe and ordinary lathe

Due to the advantages of CNC lathe in the production of hardware standard parts, it takes up more and more proportion in the production process of practice, and the economic benefits of enterprises and manufacturers are much higher than ordinary lathes. Numerical control lathe has obvious advantages compared with ordinary lathes. The specific differences are as follows:

First, numerical control lathe has a great advantage in accuracy compared with ordinary lathe

Ordinary lathes generally rely on gears and screw nuts for transmission, because there is a gap between each movement, and then coupled with the operator's manual operation is not accurate, so its repetition accuracy is relatively low. In measurement, ordinary lathes need to be manually measured after parking, so the measurement error is large. For CNC lathes, CNC lathes mainly rely on driving motor to drive ball screw transmission, ball screw through pre-stretching equipment after interference, its transmission without clearance, its accuracy mainly depends on the machine itself and program setting to ensure. And CNC lathe in the process of processing can be carried out through the encoder azimuth measurement, can compensate tool wear, and other reasons caused by the error problem, so the workpiece quality is better processed, the accuracy is more stable.

Two, CNC lathe processing parts of the qualified rate is higher than ordinary lathe

Because ordinary lathes need manual operation, the requirements for operators are higher, the human impact is also greater, if the operator's body is not good, or the mind is not focused, the processing of parts reject rate will be relatively high. And CNC lathes rely on equipment to ensure processing accuracy, operators will only play the role of loading and unloading work and switch, that is to say, the influence of small, so the workpiece pass rate is higher.

Three, numerical control lathe in the mass production processing parts than ordinary lathe efficiency is higher

Ordinary lathe although only need a skilled staff to operate equipment operation, however, due to the use manual three jaw chuck, and the need to manually after parking measurement during measurement, so will delay the processing efficiency, and numerical control lathe in batch production, using the hydraulic chuck or under the premise of spring collet clamping workpiece, A person without any operating skills can operate at least two CNC lathes at the same time, producing about four times the power of ordinary lathes.

Four, CNC lathe single processing cost is slightly higher than ordinary lathe

Numerical control lathe in processing production cost is higher than ordinary lathe, if through improvement, numerical control lathe in a single production cost and power will be better than ordinary lathe.

Fifth, CNC lathes are more expensive than ordinary lathes

Although machine tool factory CNC lathes have greater advantages than ordinary lathes in single production rate, processing parts speed, accuracy, the price of the equipment itself is more expensive than ordinary lathes, about 1.5 times more than ordinary lathes.
