The difference between ordinary lathes, CNC lathes and vertical lathes:
The ordinary lathe is driven by gears and ordinary screw nut. Due to the gap between the motion pairs and the inaccurate manual operation, the repeatability is low. When the ordinary lathe is measured, it needs to be manually measured after stopping, and the measurement error is large, and the efficiency is low. Suitable for small batch sizes, low precision requirements, and zero-active parts. Its investment is lower than that of CNC, but it requires higher operational skills for workers, so the salary level is high. The scrap rate and productivity of low-level workers can cause headaches.
The CNC lathe drives the ball screw drive by the stepping motor. Since the ball screw can have the interference, the transmission has no gap, and the accuracy is mainly guaranteed by the machine itself and the program. It can be automatically measured during machining and automatically compensates for tool wear and other causes. Therefore, the processing quality is good and the precision is stable. It is also possible to use a programmed method to drive out parts that are complex in shape and difficult to machine on a conventional lathe. Suitable for parts with high precision, large batch size and complex shape. But small batch production is also very easy to use. Its maintenance costs are higher than ordinary lathes.
The vertical car is mainly used for large parts, and its main axis is vertical. The vertical car also has numerical control. Due to the shortage of high-tech talents, new companies use CNC to increase productivity and product quality, and reduce scrap rates and costs.
