Both burrs and shock marks are common defects in the extrusion of aluminum profiles. Burr is the residual particles and very fine metal particles appear on the surface of metal parts, and shock mark is the relatively concentrated particles on the surface of the profile. The causes of burrs and shocks are multifaceted, and [...]

The burrs are found in metal casting, milling or electroplating processes, with scraps on the surface of the metal parts or very fine microscopic metal particles. The appearance of burrs will greatly reduce the quality standards of metal parts, so it should be prevented as much as possible, or try to remove burrs. Here [...]

Carburizing is a common process for heat treatment of metal surfaces. It is mostly used for low carbon steel or low alloy steel. The steel is placed in an active carburizing medium and heated to a high temperature of 900 to 950 degrees Celsius. After sufficient time, the activated carbon atoms in the carburizing [...]

For CNC machine shops, many managers say the costs are too high. These excessive costs include not only labor costs and material costs that change with market changes, but also waste of resources caused by improper management of business managers. Therefore, machine shop managers can achieve cost reduction by avoiding unnecessary waste. As an excellent [...]

Regardless of the industry in which it is engaged, management is one of the indispensable elements of an organization. This is especially true for mechanical processing plants. Since the field of machining is a labor-intensive industry, it is especially important for human management. This article will introduce some of the factors that are related [...]

When the tungsten steel milling cutter is milling, the cutting edge that participates in the cutting is long and has no free travel, so the productivity is high. There are many types of milling cutters, and their structures are different. The application range is wide. According to their applications, they can be divided into [...]

1. Surface quality problems of mechanicalproducts The quality of mechanical products is not only directly related to its performance, but also affects its service life. Generally speaking, the quality of mechanical products depends on two parts. The first is the quality of the processed parts. Some materials have their own flaw, such as easy [...]

There are many failure modes of parts, which can be classified into three types, excessive deformation, fracture and surface damage failure. Each type can be divided into several different situations. Here is mainly to share with you the form of excessive deformation failure. The so-called excessive deformation, that is, to [...]

With the development of the machining industry, more and more parts are produced by cold-moulding in production, and more and more types of cold-deformed molds are used. Cold volume die forging (cold enthalpy, cold extrusion, embossing, etc.); sheet metal stamping (such as drawing, blanking, trimming, punching, etc.); material rolling (cold rolling, rolling forming, etc.). [...]

As a mechanical design engineer, when the designed parts need to be heat treated, it is necessary to eliminate the casting stress of the material and improve the cutting performance, rigidity and wear resistance of the parts. Below we will introduce the method of heat treatment of the parts. 1. [...]

The machining error reflects the level of machining accuracy. For mechanical processing plants, to ensure the quality of the product, the first thing to do is to control the error in the processing. So, what are the common machining errors in actual production? Let's take a look at it in detail. 1. Manufacturing [...]

The mold manufacturing process is a complex process. From design, processing, assembly, commissioning to final real use, there are many factors affecting the quality of the mold throughout the life cycle, which requires the attention of the operator during the processing. What are the reasons that affect the quality of the mold? [...]

In the single-piece CNC machining, the blank is generally processed. Therefore, there will be interference of excess blank amount when the reverse machining is performed, and other tools are needed to meet the requirements. In the actual processing, although the ordinary reverse-side method can meet the requirements, there are problems such as cumbersome operation [...]

Turning is one of the most widely used in the machinery manufacturing industry. The number of lathes and worker are large, the processing range is wide, and the tools and fixtures used are numerous. Therefore, the safety technical problems of turning processing are particularly important. This article will give you a detailed introduction to the safety [...]

The occurrence of wear during machining is a common phenomenon in production.
