Ordinary lathes are driven by gears and ordinary screw nuts. Because there are gaps between each kinematic pair and incorrect manual operation, the repeatability is low. Ordinary lathe measurements require manual measurement after parking, which results in large measurement errors and low efficiency. Suitable for small batches, low precision requirements, and odd-job parts. Its investment is lower than CNC, but it requires higher operating skills of workers, so the wage level is high.
The scrap rate and productivity of low-level workers will give you a headache. Vertical lathes are mainly used for large parts, and their spindles are vertical. Vertical lathes are also CNC-controlled. Due to the increasing shortage of high-tech talents, new companies now mostly use CNC to improve productivity and product quality, and reduce scrap rates and costs. Its main axis is vertical to the ground. The difference between it and ordinary lathes is that the diameter they process is large. At this time, the diameter of the workpieces processed by the smallest vertical ordinary lathes in our country is one meter.
