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...

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 o...

Analysis on the Construction Ability of Automobile Manufacturing Plant

**The construction of automobile manufacturing plant and its casting technology level. The construction of the automobile manufacturing plant began in 1953. On March 26, 1956, molten iron was released in the foundry, announcing that the first large-scale production workshop for automobile castings in China was completed and put into production, setting a model for the overall development of casting production in the automobile industry in China. . From material preparation to sand processing, modeling and core making, metal melting and pouring, sand falling and cooling and cleaning of castings, the foundry is all carried out through casting conveyors, suspension chains, scale conveyors, and belt conveyors. And bucket elevators and other conveying equipment are integrated into a whole. Balance wheel type sand mixer, crawler type semi-automatic shot blasting cleaning drum, continuous suspension chain shot blasting cleaning room, cupola and electric furnace double smelting, lifting electric annealing furnace and other process equipment, all have foreign countries in the late 1940s and 1950s Early technical level.

Many mechanized transportation equipment connect each process into a complete production line. The modeling adopts the world-wide pneumatic vibrating or vibrating molding machine at the time, and 6 mechanized molding production lines are formed by continuous or intermittent trolley-type casting conveyors, which are respectively used for gray cast iron and malleable cast iron modeling; for modeling; The sand is sent from the sand processing department by a belt conveyor and stored in the sand bucket above the molding machine. The production line manually sets the cores. For the complex core sets used in cylinder blocks and cylinder heads, they are pre-assembled first, and then the cores are lowered with air lifting fixtures, and the boxes are manually closed. The core is made of oil sand, paper pulp sand, and grease sand. The core sand is prepared by a roller-type sand mixer; small oil sand cores are made by hand, and large sand cores are produced by a core making machine; the sand cores are dried in a chain-plate vertical continuous gas drying furnace.
