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...
The use of five-axis machining can give full play to the effects of tools. The traditional cutting environment can be improved by rotating the worktable, and the accuracy of the machined surface can be improved. For some complex parts, five-axis machining can reduce special tools, avoid interference, and save money. At a certain cost, it can also reduce the number of clamping and improve the accuracy of parts processing. Using this processing method can simplify the production process, and some complex workpieces can be easily processed, so many manufacturers use this equipment to produce products. So what are the processes for five-axis processing of agricultural equipment?
1. Modeling
Table of Contents
Before processing, we must design the parts according to the requirements. We can determine the size of the equipment by collecting relevant information. We need to design the structure according to the customer’s needs. After the modeling is completed, we must send it to the customer for confirmation and improve it based on feedback.
2. Generate tool path
After confirming the size and shape of the five-axis processing of agricultural equipment, we can use the software to generate the tool path, as long as we design the relevant parameters, in addition to checking whether it is reasonable, the software can also simulate the tool path Deal with it and confirm that it will not cause over-cutting, under-cutting, collisions, etc. If the simulation is unsuccessful, choose to adjust the parameters.
3. Processing
After confirming the tool path, you need to export the programming before you can use it. Before processing, we need to make preparations, select the appropriate blank according to the size and shape of the workpiece, and then select the appropriate Cnc Machine. The processing equipment must be cleaned and maintained before starting. Ensure that it can work normally, and you can start processing after importing the programming.
Five-axis machining has certain advantages. Many manufacturers will use this equipment, which does not require manual operation and can ensure the safety of staff. As long as regular inspection and maintenance are required, the processing process is not complicated, as long as the software is designed Good models and tool paths can be used after they are imported into the five-axis processing equipment. Before the five-axis processing of agricultural equipment, we must do a safety check to prevent accidents. After the processing is completed, we must make appropriate adjustments according to the accuracy of the parts.
