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

How can lithium batteries enter the light electric vehicle market

How can lithium batteries enter the light electric vehicle market? The following measures can be considered. **, give full play to the characteristics of lithium batteries, design light electric vehicles with higher performance. For example, install batteries of the same quality to increase the capacity of the car (driving range, climbing ability, load capacity with a single charge). Second, design light electric vehicles with 1, 2, 3, and 4 people. Third, study to improve the quality of the car and reduce the standard. Fourth, strengthen sales measures to enable it to enter the countryside and go abroad. Fifth, let lithium battery electric vehicles enter the market as soon as possible and withstand the exercise of the market.

Statistics on the number of electric bicycles in China from 1998 to 2005 * The battery field also supported and promoted the development of electronic devices. Now, light-duty electric vehicles have been widely accepted, and lead-acid batteries have played a big role. In the past 7 years, the production and sales volume has nearly doubled every year. Lead-acid batteries have occupied the position of light electric vehicles at this stage with their mature technology and lower prices.

In this period, the research work of lithium-ion batteries must be continuously strengthened. In addition to improving the performance of lithium manganate and reducing its price, it is also necessary to study new battery materials and find new materials with larger capacity, longer life, and lower cost.

The    co-precipitation method is the best preparation method. The catalyst prepared by the combination of sodium hydroxide and urea precipitation has higher activity and thermal stability. The research results of using NHO to filter out the copper component in the catalyst show that the copper content in the catalyst has a best value, and Cu plays an important role in the formation of active sites of the catalyst.
