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

Major reforms to vehicle management and vehicle traffic will be implemented

The “Highway Law of the People’s Republic of China” was passed on the 26th meeting of the Standing Committee of the Eighth National People’s Congress of Shanghai General Motors, a Sino-US joint venture company and Pan Asia Automotive Technology Center Co., Ltd., and President Jiang Zemin signed the contract and articles of association on the same day Signed at the Great Hall of the People in Beijing, signed Chairman’s Order No. 86, and promulgated the law. According to this law, Premier Li Peng of the State Council and Vice President Al Gore of the United States issued a signing ceremony for road maintenance seats after 1998. This is the largest joint venture project between China and the United States that has been paid in the form of fuel surcharges so far. The method of mainly producing specific fuel surcharges replaces the current road maintenance Fick mid-range and luxury cars with an annual production capacity of 100,000. This is a major move. However, how to implement the return is 150,000 v6 engines. The powertrain of the product needs to be further regulated by the state. The Highway Law has already equipped the 2.98Lv6 engine with a new transmission, which came into effect on January 1, 1998.

With the approval of the State Council and the Central Military Commission, the State Economic and Trade Commission, the State Planning Commission, the National Army's vehicle management and vehicle traffic will implement major reforms. Operating vehicles are changed to local number plates; the Army's Unified Scrap Standard”, and a notice was issued for this. This standard replaces the “Type 97”, retroreflective anti-counterfeiting military vehicle number plate; it will be implemented from the date of issuance. The revised new “Automobile National Road Bridges and Parking Lots Exempt Military Vehicles (Including Vehicle Scrap) Standards” has a total of 8 articles, including All the expenses of the armed police force while the car is driving. Until June 30, the internal teams such as military schedule, service life, safety, energy saving, environmental protection, etc. will change the work capacity of production and business units with local license plates. The biggest difference between the new standard and the old standard is that To be all done.

The cumulative mileage and service life of automobiles have been significantly shortened. FAW-Volkswagen Automobile Co., Ltd. is completely short. According to the model and purpose, the automobile mileage was built by the Ministry. The original 40 to 700,000 kilometers of the 100,000th car was shortened to 30-50 Audi. The valve Jetta King sedan is in batches of 10,000 kilometers, and the service life of the car has been put into production from the original. The Jetta fleet has a design capacity of 250 vehicles, which has been shortened from 14 years to 8 to 10 years, except that it is basically retained.
