Five advantages and disadvantages of CNC lathe machining
by：QY Precision 2020-03-27
CNC lathe machining can now be said to be a very popular machining process. Compared with ordinary lathes, CNC lathes are more likely to highlight its advantages. Let's analyze the advantages and disadvantages of comparison. 1. The procurement cost is high. Of course, the CNC lathe processing manufacturer said that it has certain disadvantages in terms of procurement cost and single-piece production cost. The price of CNC lathe machining of the same specification is 1. More than 5 times. 2. The cost of single-piece processing is currently high. It is an indisputable fact that the current CNC lathe processing is higher than the production cost of ordinary lathe single-piece processing. However, if improved, the cost and efficiency of CNC lathe processing in single-piece production will also be better than that of ordinary lathes. 3. Precision advantage ordinary lathe machining is driven by gears and ordinary screw nuts. Due to the gap between the sports pairs and the inaccurate manual operation, the repetition accuracy is low. When measuring ordinary lathes, manual measurement is required after parking, and the measurement error is large. 4. The qualification rate advantage ordinary lathe processing is manual operation, and the human influence is very large. Once the operator's physical condition is not good or the mind is not concentrated, the product rejection rate will rise sharply. CNC lathe machining basically relies on equipment to ensure machining accuracy. Operators basically only play the role of loading and unloading parts and switches, and there is little human influence, so the product qualification rate is relatively high. 5. Advantages of mass production efficiency a common lathe processing requires a skilled operator. Due to the use of manual three-jaw chuck and the manual measurement after stopping during measurement, the processing efficiency is low. On the premise of mass production and clamping workpieces with hydraulic chucks or spring chucks, a worker who does not understand any technology can operate at least two CNC lathes at the same time. The production efficiency is more than 4 times that of ordinary lathes. CNC lathe machining drives the ball screw drive by driving the motor. The ball screw has a surplus after pre-stretching installation, and there is no gap in the transmission. The accuracy is mainly guaranteed by the machine itself and the program. Position measurement can be performed by Encoder during machining, which can compensate for tool wear and errors caused by other reasons. Therefore, the processing quality is good and the precision is stable. Did you learn?
