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

Because the concentration of the mixture is controlled by the idling oil needle when the engine is idling

 

The vacuum at the main nozzle of the throat and the idle nozzle disappears, fuel is no longer sprayed, and the fuel is replenished to make the oil chamber pressure equal to the atmospheric pressure when the diaphragm is in a balanced position. The pressure valve is closed to start enrichment. It is required to supply a relatively rich mixture when starting. Therefore, it is necessary to press the start enrichment lever before starting to open the pressure regulating valve. The fuel flows into the fuel chamber under the action of gravity and overflows from the nozzle. Enrichment.

When starting, you can also close the small air door to increase the degree of each nozzle to enhance the fuel suction effect, supply excess fuel, and thus play the role of enrichment. The damper should be opened immediately after starting, otherwise the engine will stall due to the excessively rich mixture. The adjustment of the carburetor will directly affect the starting idle speed and acceleration power and fuel consumption of the engine.

The factory’s wind power extinguisher has been adjusted. After the carburetor is cleaned and maintained, the oil needle of the Sichuan vacuum pump should be adjusted to the original position, the specific adjustment method. When the engine is idling, the concentration of the mixture is controlled by the idling oil needle. When screwing in to become thinner, the speed increases, and when screwing out to become rich, the speed decreases. It is adjusted until the engine can run stably at idling speed, and it can also be smooth when accelerating. Increase the throttle of the transition, the engine does not stall until it stops.
