Both Ra and Rz values are representations of surface roughness, what do they mean and what are the differences between them? Let’s learn about what is Ra value in surface finishing, the Ra value chart for different machining processes, and Ra vs Rz. What is Ra Value in Surface Finishing? Ra is a measurement unit of surfac......

Some types of CNC machined parts need to achieve close tolerances, so a surface finish is required. There are various finishing operations like polishing, buffing, and lapping. In this article, we are going to talk about what is lapping process, is and what is the difference between lapping and polishing. ......

At present, as a new technology, 3D printing has no official authoritative classification. In terms of technical realization, it can be roughly divided into five categories: FDM, SLA, LOM, 3DP, and laser melting technology. Let’s briefly introduce them one by one. 5 Common Types Of 3D Printing Technologies 1. Fused ......

Controlling the processing quality of CNC turning parts is the key point to promote the development and progress of work, so it needs to be treated seriously. This article will discuss the content of this aspect, analyze the relevant quality processing problems of modern CNC turning parts in detail, and conduct a detailed study on the parts that need to be strengthened and improved in the work, aiming to comprehensively promote the progress and improvement of the processing quality of CNC turning parts on this ba......

There are two important parameters in the process of NC machine tool processing, namely feed rate and cutting speed. These two parameters affect the manufacturing efficiency of CNC machines, the quality of machined parts and the service life of tools in real time. Cutting speed measures power consumption and tool life. The feed rate controls the surface roughness and processing time of the finished product. This paper mainly introduces the importance of feed rate and cutting speed of CNC machines. ......

The commonly used processing mechanical equipment in the manufacturing industry is the lathe. However, in the long-term operation process, the wear or deformation of the lathe spindle will increase the error of the lathe or change various clearances, which will interfere with the machining accuracy of the lathe, and even affect its production rate and operation safety. The article will explain the method of adjusting the lathe spindle bearing clearance in detail.  ......

Motion control is mainly divided into two directions, one is motion control, which is usually used in the field of automatic machinery. The other is process control, which is usually used in the chemical industry. Motion control is a kind of servo system which originated in the early days. based on the control of the motor, it can control the angular displacement, torque, speed and other physical changes of the object. This guide briefly introduces the motion control methods of CNC machines. ......

The surface quality of automobile parts can directly reflect the micro and geometric errors of the surface of the parts. Of course, the surface roughness is also an important indicator of the reaction, and it is an important basis for testing the surface quality of the parts. Whether the selection is reasonable or not will directly affect the later product quality and service life, including the production process. The selection methods of the surface roughness of mechanical parts mainly include calculation metho......
