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 [...]
Since the widespread use of high-speed milling technology, there has been a point that high-speed milling can completely replace EDM. Is this really true? the answer is negative! High-speed milling and EDM technologies have their own characteristics, and the two cannot completely replace each other. This article will provide an in-depth analysis of the [...]
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 [...]
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 [...]
