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

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

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

Improve the heat transfer performance of the radiator. Compared with the series-fin reinforced radiator, the tube band radiator has the following main features. Heat dissipation port 2. When the air resistance of the tube-belt radiator can be reduced but the heat transfer coefficient increases, the heat transfer performance of the two radiators is compared. The characteristic of the tube-belt radiator tube belt is called the enhanced series fin radiator.

The key element of the tube-belt radiator is the corrugated belt, which is sectioned or not sectioned into a certain angle during rolling. Of wrong mouth shutters. In this way, it is beneficial to thin the adhesion layer of the airflow boundary layer on the corrugated belt, which can greatly increase the heat release coefficient of the air side, thereby saving copper tube. Compared with the reinforced radiator, each section can save the bottom of the copper tube plate. Including the reinforcement plate, each section of tube-belt radiator saves copper masking material. If calculated in ton of market price, the cost per locomotive of the main models of Ziyang Diesel Locomotive Factory can be significantly reduced. Moreover, in the brazing of the cooling flat tube end and the tube sheet, the reinforcing plate plays the role of increasing the weld seam, thereby enhancing the strength of the brazing seam. The gas welding process is simple and the production efficiency is high. It is rolled by a wave machine, omitting the cumbersome process of punching fins and fins in the production of fin-type radiators, and it is very convenient to assemble the radiator cooling core. The tin-baking furnace for cooling the core brazing and the hanging tin machine for cooling the flat tube can be used in common with the series-fin radiator. In addition, the hob for rolling the corrugated belt and the matching rolling machine are durable and can be adapted to the series of variable-depth tube belt radiators.
