Slow wire walking, also called low-speed wire walking, is a kind of CNC machining machine tool that uses continuously moving fine metal wire as an electrode to pulse spark discharge on the workpiece to generate a high temperature of over 6000 degrees, ablate metal and cut into a workpiece. The principle of wire processing is the phenomenon that there is a gap between the wire electrode and the workpiece, and the metal is removed by continuous discharge. Since the slow-moving wire cutting machine adopts the method of wire electrode continuous feeding, that is, the wire electrode is processed during the movement, so even if the wire electrode is worn out, it can be continuously supplemented, so it can improve the machining accuracy of the parts and slow the wire. The surface roughness of the workpiece processed by the cutting machine can usually reach Ra=0.8μm and above, and the roundness error, linear error and dimensional error of the slow-moving wire cutting machine are much bett...
The Purpose Standardize the management of the scrapping of the company's metal stamping dies, prevent the loss of company assets, and formulate this system specially. Scope of application It is suitable for the management of the company's scrap molds. Definition If the molds listed in the assets of the company fall under one of the following circumstances, the use management department may apply for scrapping. 1. Molds that exceed the specified service life. 2. The mold is severely damaged by accidents or accidents, and molds that cannot be repaired or have no repair value. 3. Metal stamping dies that have not reached the service life, but due to safety, quality, efficiency and other issues, the repair still fails to meet the minimum requirements of the customer's product process or affects the production safety and efficiency. 4. Product customers have stopped placing orders or have not placed orders for molds in several years. 4. Responsibilities 1. Responsibilities of th...
KOVAR parts are commonly used as metal casing materials in the electronic packaging industry. Because they have a linear expansion coefficient close to that of molybdenum group glass, and can produce less sealing stress during the sealing (melting) process with molybdenum group glass, so To obtain good air-tightness, in order to make the metal tube and shell to achieve air-tight sealing, in the entire sealing process, the annealing process undoubtedly plays an important role as a link between the previous and the next. The internal stress generated during KOVAR machining also prepares the material structure for the implementation of the subsequent process-the sealing process of the metal parts. The main purpose of annealing Kovar shell before sealing is to: (1) Eliminate machining stress. When Kovar undergoes plastic machining deformation during cold working, about 10% to 15% of the applied energy is converted into internal energy, which is commonly referred to as internal stre...
With the rapid development of the equipment manufacturing industry, five-axis machining is also widely used in aerospace, medical equipment, military and other fields. In fact, five-axis machining is a common Cnc Machine tool processing mode, mainly used for various electronic components. Sealing, five-axis processing of plastic parts is now a more common processing application, so what are the advantages of this type of processing?
1. Shorten processing time
Table of Contents
Reliable five-axis processing of plastic parts can realize processing angle avoidance, that is, one-time clamping can complete five-sided processing, so that one-time clamping can avoid repeated positioning errors caused by multiple clampings, and can Save a lot of time, on the one hand, it can improve work efficiency, on the other hand, it also shortens the time from product production to transportation, which has a good role in promoting product sales.
2. Reduce costs
With the popularization of various machine simulation software at home and abroad, the cost-effective five-axis processing of plastic parts can be programmed by importing blank data. As a representative of engineering intensive production, it can reduce the investment of other equipment in the production process, thereby reducing In addition to the cost of investment, it can also reduce the number of workshops and the area occupied by the workshops.
3. It can be automated
As we know, the five-axis machining of plastic parts can reduce the dependence on fixtures. Regular workpieces can be clamped with three-jaw or four-jaw chucks. Irregular workpieces can also be used with corresponding tools. No special tools are required. Fixture, this method can reduce the participation of personnel, and can realize automatic operation for simple procedures, thereby improving the intelligence of the processing process.
Equipment manufacturing is an indispensable industry. As a new type of processing mode, five-axis processing of plastic parts plays a vital role in the production of manufacturing equipment. The advantages mentioned above are just the tip of the iceberg. With the continuous development and breakthrough of high-tech, it will definitely contribute more strength and lay a better foundation for the higher level of my country’s equipment manufacturing industry in the future.
