The difference between servo systems for CNC lathe processing

CNC lathe machining is a high-precision and high-efficiency automated machine tool machining method that uses digital information to control the displacement of parts and tools. It provides an effective way to solve the problems of variable varieties, small batches, complex shapes and high accuracy such as aerospace product parts, and other problems, and achieve high efficiency automated processing. Moreover, CNC lathe processing is divided into three servo systems: open loop, closed loop and semi-closed loop. Let’s take a look.

1. Open loop: The machine tool has no feedback information from the position sensor. After the CNC lathe machining completes the part program, digital instructions are transmitted to the servo system, so that the dynamic structure of the driving head bed is simple, economical and convenient, but the speed and accuracy are low, suitable for small and medium-sized machine tools with low accuracy requirements, and are mostly used for CNC transformation of old machine tools.

2. Closed loop: The machine tool is equipped with a position detection device, which can directly measure the workpiece with high precision displacement, but the system design and adjustment are relatively cumbersome, the structure is complex, and the cost is high. It is mainly used for high-precision drilling, super-competent machines, and super- Weekly milling machine, machining center, etc.

3. Semi-closed servo system: This CNC machine tool can measure the rotation angle of the screw by the angle set on the feed screw or electronic head end to obtain accurate and rapid feedback information on the position information, thereby realizing Accurate positioning, such as CNC lathes, CNC milling machines, machining centers, etc.

That’s all for today’s explanation. The above is all about today. I believe everyone has a certain understanding of the differences between open-loop, closed-loop and semi-closed-loop servo systems Thank you for your patience to read.
