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 [...]
A measuring tool is a tool that measures the size, angle, and curvature of a workpiece during machining or after inspection. There are many types of measuring tools, such as vernier calipers, spiral micrometers, universal angle rulers, needle gauges, lever dial indicator, gauges, feeler gauges and coordinate measuring instruments. Vernier caliper [...]
CNC machining is the most widely used machining method at present, and it is also the basic skill that every machining worker must master. After the start-up, workpiece clamping, workpiece hit count, preparation tool and processing parameters are set, it enters the start-up process. In this process, what precautions need to be noticed by the operator, [...]
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. [...]
