CNC lathe technology is currently the most widely used. We have talked about that some products which are difficult to be processed by general machine tools need to adopt CNC lathe technology. So what are the main processing objects and contents of this technology? Although CNC lathes are similar in structure and processing technology to ordinary lathes,  CNC turning parts  in  China  are controlled by electronic computer digital signals through pre-programmed machining programs, so there are many differences. It has many requirements, high machining precision, automatic shifting, and linear and arc interpolation. The ordinary lathe cannot meet these conditions, and the processing range is not wide. Therefore, compared with the ordinary lathe, the main processing contents of  CNC turning parts  are turning outer circle, turning inner hole, turning end face and turning thread. The main processing objects are also the following. 1. Parts with high pre...

Surface roughness is a very important index in the field of machining parts. So you know how to choose the surface roughness when  machining parts ? Next, we will share it with you.  Surface roughness is an important technical index to reflect the micro-geometric error of the surface of the parts. It is the main basis for the inspection of the surface quality of the parts, and the selection of the product is directly related to the quality, service life and production cost. There are three ways to select the surface roughness of machine parts, they are the algorithm, test method, and the analogy method. In the design of mechanical parts, the most common method is the analogy method. This method is simple, rapid and effective. The application of analogy requires to need sufficient reference materials. All the existing mechanical design manuals have provided comprehensive information. And the most commonly used surface roughness is the tolerance grade. In general, the smaller th...

The burr is found in the process of metal casting, milling or electroplating. It is a metal particle on the surface of  metal parts . Artificial Removal of the Burrs The operator uses tools such as files, sandpaper, grinding head and so on to polish the workpiece and remove the burrs. This method need not have technical requirements for workers. It is suitable for products with small burrs and simple product structure, so it is also widly used in general enterprises to remove burrs. The file is divided into two kinds: artificial file and pneumatic file. The cost of artificial file is expensive, and the burr efficiency is not very high, and it is difficult to remove complex cross holes.  Die deburring The burrs are removed by making punch. It is necessary to make rough die and fine blanking for stamping burrs, and it may be necessary to make the sizing die. This method is suitable for products with simple joint face, and the efficiency and effectiveness of removing burrs ...

The screw thread is often shortened to the thread, is a helical structure used to convert between rotational and linear movement or force. A screw thread is a ridge wrapped around a cylinder or cone in the form of a helix, with the former being called a straight thread and the latter called a tapered thread. A screw thread is the essential feature of the screw as a simple machine and also as a fastener. According to its position in the body is divided into external thread(male), internal thread(female), according to its cross-sectional shape (dental) is divided into triangular thread, rectangular thread, trapezoidal thread, zigzag thread and other special shape thread. Thread Handedness The helix of a thread can twist in two possibledirections. Most thread s are oriented so that the threaded item when seen from a point of view on the axis through the center of the helix, moves away from the viewer when it is turned in a clockwise direction, and moves towards the viewer when it i...
