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...

The society is constantly advancing. Today's lathe processing technology is spread all over the transportation, industrial and general machinery industries, and it is developing rapidly and comprehensively. Gradually, consumer demand for intelligent and automated machine tools is increasing, especially for turning precision and process changes. Everyone's high requirements for machine tools are a good thing for our turning parts processing center. They can promote our learning and new technologies and apply them to the actual situation, that is, to promote their own development and meet the needs of customers. As a  CNC turning manufacturer , although Shengtang is constantly introducing new technologies, we need to learn a positive and innovative attitude. So what is efficient cutting technology? Efficient cutting technology is mainly a concept of machine tools, tools, and cutting fluids, and is an integrated processing technology. High-efficiency cutting is a systematic ...

CNC technology is a technology that uses digital information to control mechanical motion and work processes. The application of CNC technology not only brought revolutionary changes to the traditional manufacturing industry but also made the manufacturing industry a symbol of industrialization. ​ CNC machine tool is a high, precision, pointed technology in one, set machine, electricity, light, the liquid in one of the high-tech products. It has many advantages such as high processing precision, stable and reliable processing quality, high production efficiency, strong adaptability and good flexibility. It becomes popular in various industries and is receiving more and more attention in terms of use. To use the CNC lathe for turning parts, first of all, a step-by-step determination plan should be made, that is, the preparation work before the operation is clearly defined. The principle of positioning benchmark selection 1) The principle of benchmark coincidence. In order to avoid the r...

High efficiency and high precision machining are one of the most important features of CNC machine tools. The positioning and clamping of the workpiece within the fixture are particularly important during the processing of the product. The product must be reasonably positioned according to the six-point positioning. Under-positioning, full positioning or over-positioning must be determined according to the actual production process. The fixture is a clamping device that covers almost all operations from machining to assembly. Since a large number of machining operations require clamping, the fixture design becomes very important in the manufacturing system, which directly affects the quality of processing, productivity and manufacturing cost. Turned parts   must follow the six-point positioning criteria: Full positioning — all six degrees of freedom are limited. Incomplete positioning (partial positioning) — Six degrees of freedom are not (and not necessarily) all limited. ...

Before processing the  machining parts , we should draw a drawing, which marks the processing requirements of the machining parts, but it can not guarantee that every part of the processing can reach the standard, so it will be accepted after the test. So, do you know what the acceptance of  machining parts  includes?  Specifically, this includes acceptance requirements and acceptance procedures: 1. Acceptance requirements (1) Appearance check A: Check whether the finish of machining parts meets the requirements of drawings. B: Check whether the surface of the machining parts is damaged, rusty, bruised, and whether the thread shape and angle are correct. C: If the above problems are found, detailed records should be kept for reference. (2) Quantity acceptance A: Based on the supply contract and processing voucher, the material, specifications, and quantity of the processed parts should be checked strictly against the drawings and should be checked one by one. B: Do a...

The processing technology of  precision mechanical parts  is not limited to the national defense and Aeronautics and Astronautics, and it has been extended to many fields of national economy, and the scale of the application has also increased greatly. Well, do you know the scope of the application of  precision mechanical parts ?  Computers, modern communications, film and television communication and other industries now need precision, ultra-precision processing equipment, as its rapid development of the support conditions. The precision and ultra-precision machining of the computer disk, the magnetic head of the VCR, the multifaceted prism of the laser printer, the photoreceptor of the photocopier, and other parts, all of them adopt the high efficient and large batch production mode. Sophisticated and ultraprecision processing technologies in developed countries such as the United States, Britain, Japan, Germany, and Holland are in the front row in the world. Thi...

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...
