Lathe processing is a high-precision, high-efficiency automatic machine tool, which uses digital information to control the displacement of parts and tools. This is an effective method to solve a variety of aviation products, small batches, complex shapes, high precision, high efficiency and automatic processing. The article will introduce in detail what are the processing characteristics of CNC lathes.
The lathe is a truly time-honored tool with a history of hundreds of years and can be used to produce parts for machines and many complex objects. Different turning tools or other cutting tools can be used in the lathe to process various rotating surfaces, such as inner and outer cylindrical surfaces, threads, turning grooves and end faces.
CNC Turning has been widely used in the machining industry of mechanical parts. It also improves product quality and increases the value of machinery parts manufacturers. Knowing the processing characteristics of CNC Turning helps us understand the production equipment of CNC lathes more quickly.
More CNC Turning has been more and more used in modern manufacturing, and it has played an incomparable advantage over ordinary lathes. Compared with ordinary lathes, CNC lathe processing has the following characteristics:
1.The transmission chain of CNC Turning is short, and the belt is no longer the transmission gear pair mechanism of the motor compared with the ordinary lathe spindle drive. Instead, the horizontal and vertical feeds are driven by two electric servo motors respectively, instead of using traditional parts. For example, wheels, clutches, and transmission chains have been greatly reduced.
2. High rigidity, in order to match the high-precision CNC system, the high-rigidity machining of the CNC lathe is suitable for high-precision machining.
3. Turning adopts ball screw pair, which has little friction during movement and is easy to move. At the end of the screw bearing type bearing, the pressure angle is greater than that of the ordinary bearing selected at the factory. The lubrication part of CNC Turning adopts automatic oil mist lubrication. These measures make it possible for mobile portable CNC Turning.
4. CNC lathes with cams and stoppers as control elements are stable and reliable, and still account for the majority of CNC lathes. However, when replacing the workpiece, the cam needs to be redesigned and manufactured, and it takes more time to adjust the lathe, so it is only suitable for mass production.
Rotating parts with complex contours or difficult to control size: Because CNC turning centers have linear and circular interpolation functions, some CNC turning centers have some non-circular interpolation functions. With curve interpolation function, it can rotate rotating parts composed of arbitrary plane curve contours, including parts obtained by fitting calculation.
The accuracy requirements of high-precision parts mainly refer to the accuracy requirements of the size, shape and surface of the workpiece, and the surface accuracy refers to the surface roughness. For example, cylindrical parts with high dimensional accuracy and high cylindricity requirements. Conical parts with higher requirements for straightness, roundnessf and inclination. Parts with higher requirements for line contours (fine contour shapes) can also be processed with very high geometric contours on special precision CNC lathes.
Processing of hardened workpieces In the processing of large molds, many parts are large in size and complex in shape. The deformation of these parts after heat treatment is very small. Due to the large size, it is difficult to grind hardened parts. Use turning processing instead of grinding processing to improve processing efficiency.
Machining complex workpieces needs to rotate the outer circle, end face, side milling groove, and drilling. This kind of workpiece generally needs three lathes for processing. Lathes, milling machines, drilling machines, loading and unloading materials are very troublesome, and can be processed with a turning center.
The article mainly introduces the processing characteristics of CNC lathes. By browsing the article, you can understand that using CNC Turnings to process complex-shaped parts can not only improve labor productivity and processing quality, but also shorten the production preparation cycle and reduce the requirements for the technical proficiency of workers.
