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 better t

Classification of CNC Machining Occupation Levels

1. Blue-collar layer:   That is, CNC machining operation technicians, proficient in machining and CNC machining process knowledge, proficient in the operation and manual programming of CNC machine tools (attributes: automated machine tools), understand automatic programming and simple maintenance of CNC machine tools (attributes: automated machine tools), such There is a large market demand for personnel, and they are suitable for operating workers of CNC machine tools (attributes: automated machine tools) in the workshop, but due to their single knowledge, their wages will not be much higher.   2. Gray collar layer:   One, CNC machining programmer:   Master the knowledge of 5 Axis CNC machining Aluminum   technology and the operation of CNC machine tools (attributes: automated machine tools), be familiar with the design and manufacturing expertise of complex molds (title: mother of industry), and be proficient in 3D CAD/CAM software, such as UG, GOOGLE PRO/E, etc. ; Familiar with CNC

Hydrostatic guideway of CNC machining lathe

The static pressure slide rail (TTW guide) of the CNC machining lathe transfers the oil with a certain pressure through the throttle to the oil cavity between the sliding surfaces of the slide rail (TTW guide) to form a pressure oil film to float the moving parts , Make the sliding rail (TTW guide) surface in a pure liquid friction state.   CNC machining General CNC machining usually refers to computer digital control precision machining, CNC machining lathe, CNC machining milling machine, CNC machining c17200   beryllium   copper   and milling machine, etc. The feed route of finishing is basically carried out along the part contour sequence. Therefore, the focus of determining the feed route is to determine the feed route of rough machining and idle stroke. In the numerical control processing, the control system issues instructions to make the tool perform various motions that meet the requirements, and the shape and size of the workpiece are expressed in the form of numbers and lette

2018 Sheet Metal Industry Development and Technology Report

In 2017, the sheet metal industry as a whole performed relatively well. Passenger cars in the automobile industry increased slightly, and commercial vehicles grew significantly. However, some industries, including the automobile industry, have not yet achieved their goals. Most suppliers and users are experiencing the serious drawbacks of vicious price competition. Some major companies are starting to deal with price issues reasonably. In the market segment, colleagues start communicating and seek differentiated development. This is a relatively big change in the sheet metal industry in 2017. In addition, thanks to major adjustments to the steel industry, steel prices changed significantly in 2017, putting significant pressure on forging, pressing and stamping. Sheet metal production company. Current situation analysis shows that this growth trend has slowed and will continue in 2018, with no apparent fluctuations in demand and supply of steel.

Key points of the sheet metal industry analysis report:

  • 1) Life cycle of the sheet metal industry. Determine the stage of industry development through market growth, demand growth, product categories, number of competitors, entry / exit barriers, technological changes, user purchasing behavior, etc. in the sheet metal industry
  • 2) Supply and demand balance in the sheet metal industry market.Understand the saturation of the industrial market by providing the demand situation and import / export conditions of the sheet metal industry.
  • 3) Competitive environment in the sheet metal industry.To master the bargaining power, the bargaining power of the buyer, the ability of potential competitors to enter capacity through the sheet metal industry supplier, the ability to replace products, the current competitiveness of the industry’s competitive analysis, the level of the profitable industry. Decide.
  • 4) Economic management of the sheet metal industry.Primarily used for data analysis including number of competitors, number of employees, industrial production value, sales, export value, finished products, sales, gross profit, assets and liabilities in the sheet metal industry, industry growth potential, profitability , Debt repayment ability, business ability.
  • 5) A major player in market competition in the sheet metal industry.Includes the company’s products, business terms (BCG), financial status, competitive strategy, market share and competitive (swott analysis) analysis.
  • 6) Analysis of investment, financing and M & A.Includes investment and financing project analysis, M & A analysis, investment areas, return on investment, and investment structure.
  • 7) Marketing in the sheet metal industry.Marketing concept, marketing model, marketing strategy, channel structure, product strategy, etc.

Forging, stamping and sheet metal manufacturers must pay attention to the development of the medical bed industry. It is understood that almost all high-end beds are imported. With the continuous development of China’s medical system, there is a great demand for medical equipment and medical equipment (including hospital beds). It will grow steadily in 2018.
According to an analysis of the current state of the consumer electronics industry, the use of electric and gas cookers will make great strides. Some rural areas of China will steadily develop electricity, oil and natural gas as fuels, which are huge potential markets. It is also an important national strategy for China to expand its oil and gas imports. In 2018, we need to focus on this market and make the necessary preparations.

Commercial aircraft is an area of ​​future development. The state will provide a support policy for the production of commercial aircraft and parts next year. Therefore, this is in the direction of business opportunities and will develop in 2018.

3D printing (or additive manufacturing) is a fast-growing new industry. Currently, many companies are unable to fully sell and offer 3D printing equipment. In 2018, it was listed as a support project. Forging, stamping and sheet metal manufacturers that support 3D printing equipment need to pay particular attention to future developments and business opportunities in the industry.
Mobile payment devices, cash books, industrial monitoring devices, display devices, financial devices, environmentally friendly devices (vehicles), and security inspection devices involved in the stamping and sheet metal manufacturing industries are still evolving industries. Over the next few years, supermarket automatic cash register systems will be a relatively fast growth point and should attract the attention of some companies. In particular, according to the Ministry of Transport’s plan, automatic registration and payment of highway ports, ETC equipment installation locations, and automatic parking payment systems will be new growth points in the next few years and need to increase in 2018. be.
