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

알루미늄 합금 다이캐스팅의 단점을 해결하는 것이 편리합니다!

알루미늄 합금 다이캐스팅은 현재 현재의 전자제품, 자동차, 생활필수품 많은 산업과 분야에서 널리 사용되고 있습니다. 그러나 알루미늄 합금 다이캐스팅에서 자주 발생하는 가지 결함 해결 방법은 다음과 같습니다.

 

알루미늄 합금 다이캐스팅

 

1. 불순물

 

알루미늄 합금 다이 캐스팅의 불순물 문제는 주로 특정 온도에서 알루미늄, 규소 다량의 , 망간, 크롬 기타 화합물을 포함하는 결정립과 일부 산화물로 구성됩니다.

 

해결책: 알루미늄 잉곳의 조성을 엄격하게 제어하고, 제련로의 난로를 정기적으로 청소하고, 정기적으로 슬래그를 처리하면 문제를 해결할 있습니다.

 

2. 구강 문제

 

다공성은 다이캐스팅 부품의 내부 또는 표면에 나타나는 다양한 크기의 구멍을 말하며, 이는 다이캐스팅 부품의 경도 부족으로 이어져 표면의 외관에 영향을 줍니다.

 

Solution: 적절한 정제제를 사용하여 모공을 처리하고, 공정을 조정하고, 저속을 적절하게 줄이고, 이형제가 너무 많이 분사되어 모공 문제가 해결되지 않는지 확인하십시오.

 

3. 균열 문제

 

균열은 알루미늄 합금 다이캐스팅의 매트릭스가 파괴되고, 외력의 작용에 따라 확장되는 경향이 있는 선형 또는 기타 라인인 기다란 틈이 형성되는 것을 의미합니다.

 

솔루션: 합금 조성을 올바르게 제어하고, 냉각수 회로를 늘리고, 알루미늄 합금 다이캐스팅의 구조를 변경하고, 사출 위치를 변경하거나 증가시키면 해결할 있습니다.

PINJIN서비스에는 다음이 포함됩니다. 알루미늄 다이캐스팅,아연 다이캐스팅,마그네슘 다이캐스팅,투자 주조,모래 주조,분실된 거품 주조,CNC 밀링,CNC 터닝,5 CNC 가공,정밀 가공,신속한 프로토 타입,와이어 방전가공
