Working principle of slow wire processing

 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...

What are the rules for metal stamping die scrap tube?

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...

Introduction of KOVAR parts

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...

Give full play to the distribution channels of auto parts companies

Through the development of wholesale business, the auto parts company’s role as a reservoir of circulation channels is promoted to promote the formation of a hierarchical sales network in the auto parts market. Social outlets are mostly small-scale operations, and are restricted by storage conditions and the variety of models and varieties of repair parts. They always hope to obtain small-batch and multi-batch purchase resources from local wholesale companies. In the past two years, our company has maintained a certain share to carry out wholesale business to social outlets. The normal operation of some outlets has been fostered, and the company’s main channel sales market share and market coverage have been increased. Promote the formation of a hierarchical network of auto repair parts market.

In order to further play the role of the reservoir of the main circulation channel, enhance the ability to control the market, ensure supply and sales, and facilitate market management, we summarize the work of the previous stage. In response to these situations, we will focus on market mechanisms in our actual work. , Explore a reasonable balance between the supply and demand of auto parts, establish a supply and demand mechanism suitable for the market economy and its own characteristics, and put forward the following suggestions: Set up a leading group for clean-up and rectification. The auto parts sales industry is entrusted by the government to be responsible for the relevant departments, and the industrial and commercial administration, price management and other departments have been established to participate in the leading group and formulate rectification regulations. Re-examine the business qualifications. Strictly follow the relevant rectification regulations to re-examine the business qualifications of auto parts business units. Regardless of the main or concurrent business units, regardless of their affiliation and economic form, all the original business licenses that have auto parts business content must be designated to clean up. Reorganize registration. First, to regain business qualifications, it is necessary to have business sites and facilities that are compatible with the operation of livestock enclosures and business methods, and potatoes have funds that are commensurate with the scale of business, employees and qualified professional and technical personnel, such as quality inspectors and price member.

The automotive parts and parts machining, PTJ Shop offers the highest degree of OEM service with a basis of 10+ years experience serving the automotive industry. Our automotive precision shop and experts deliver confidence. We have perfected the art of producing large component volumes with complete JIT reliability, backed by the quality and long-term reliability our customers expect.
