What is the difference between CNC lathe and common lathe
The difference between CNC lathe and common lathe is as follows:
1. Different meanings
The spindle of common machine tools needs to be in the spindle box. The motor transmits torque through the belt and gears with different transmission ratios to realize the processing of the workpiece.
CNC machine tool is a digital control machine tool, an automatic machine tool equipped with a program control system. The control system can logically process a program with a control code or other symbolic instructions, decode it, express it with coded numbers, and input it into the numerical control device through an information carrier. After arithmetic processing, the numerical control device sends out various control signals to control the action of the machine tool, and automatically process the parts according to the shape and size required by the drawing.
2, the structure is different
Common lathes use gear to change speed, which requires turning the shift handle to change speed. CNC lathes generally use numerical control programs to change speed. common lathes use trapezoidal threaded screws to process threads and polished rods for cutting. CNC lathes all use ball screws. The tool post of common lathes is generally on the operator's side, the tool post of CNC lathes is mostly on the opposite side of the operator, and the tool post of economical CNC lathes is on the operator's side.
The guide rails of common lathes are hard rails, and the guide rails of CNC lathes have hard rails and linear rails. common lathes have large carriage handles, middle carriage handles, and small carriage handles. CNC lathes do not have these handles and do not have small carriages.
3, the operating efficiency is different
Common lathes are driven by gears and common lead screws and nuts. Due to the gap between the motion pairs and the inaccurate manual operation, the repeat accuracy is low. common lathes need to be manually measured after the machine is stopped during measurement. The measurement error is large and the efficiency is low. It is suitable for small batches, low precision requirements, and zero-working parts. It has lower investment than CNC, but requires higher operating skills for workers, so the wage level is higher. The scrap rate and productivity of low-level workers will give you a headache.
CNC lathe adopts a fully enclosed or semi-enclosed protective device. Use automatic chip removal device. The spindle speed is high, and the workpiece clamping is safe and reliable. The hydraulic chuck is adopted, the clamping force adjustment is convenient and reliable, and the labor intensity of the operator is also reduced. The tool can be changed automatically.
CNC lathes all adopt automatic rotary tool post, which can automatically change the tool during the processing, and continuously complete the processing of multiple processes. The main drive and feed drive of the CNC lathe adopt independent servo motors to make the transmission chain simple and reliable. At the same time, each motor can move independently or realize multi-axis linkage.
Taiye CNC lathe, use taiye fool-like operation system, Higher efficiency, better price, Taiwan industry machinery, extrusion die equipment production experts.
