What are the advantages of CNC machining of radiator parts?

For friends who have been in contact with the radiator component industry, they often see or hear "CNC machining", but too much exposure does not necessarily mean that many people understand. In fact, many questions are still about CNC machining. What are the advantages? Let's take a closer look. CNC machining is an index-controlled machine tool machining, which is a method of using digital information to control the machining process. Traditional mechanical processing is done manually by machine tools. During processing, the mechanical cutter is shaken to cut metal, and the accuracy is measured with calipers and other tools. However, traditional artificial intelligence processing is far from being able to meet the needs of production development. Therefore, the emergence of CNC machining provides the possibility for the standardization, precision and efficiency of mechanical product processing. The CNC machining process in the radiator component industry also shines. The

Investment Casting Materials and Manufacturing Process

Mold material The performance of the molding material should not only ensure the convenient production of investment molds with accurate dimensions and high surface finish, good strength and light weight, but also create conditions for the manufacture of mold shells and good castings. Molding materials are generally formulated with waxes, natural resins and plastics (synthetic resins). All mold materials mainly prepared with wax materials are called wax-based mold materials, and their melting point is low, 60~70 ° C; all mold materials mainly prepared with natural resins are called resin-based mold materials, with a slightly higher melting point, about 70 °C. ~120℃. invest-casting.com   Precision Investment Castings China prototype company service include :  High Quality Investment Casting Parts Custom , Lost Wax Investment Casting Sand Casting , Lost Foam Casting , Gravity Casting , Die Casting , Graphite Casting , Casting Moldsmanufacturers .

알루미늄 합금 다이캐스팅의 단점을 해결하는 것이 편리합니다!

알루미늄 합금 다이캐스팅은 현재 현재의 전자제품 , 자동차 , 생활필수품 등 많은 산업과 분야에서 널리 사용되고 있습니다 . 그러나 알루미늄 합금 다이캐스팅에서 자주 발생하는 몇 가지 결함 및 해결 방법은 다음과 같습니다 .   알루미늄 합금 다이캐스팅   1. 불순물   알루미늄 합금 다이 캐스팅의 불순물 문제는 주로 특정 온도에서 알루미늄 , 규소 및 다량의 철 , 망간 , 크롬 및 기타 화합물을 포함하는 결정립과 일부 산화물로 구성됩니다 .   해결책 : 알루미늄 잉곳의 조성을 엄격하게 제어하고 , 제련로의 난로를 정기적으로 청소하고 , 정기적으로 슬래그를 처리하면 문제를 해결할 수 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 수 있습니다 . PINJIN 서비스에는 다음이 포함됩니다 . 알루미늄 다이캐스팅 , 아연 다이캐스팅 , 마그네슘 다이캐스팅 , 투자 주조 , 모

The key technology that needs to be solved in the MQL micro-lubrication processing of gear hobbing

<strong>(1) </strong><strong>High hobbing speed</strong><br /> Generally, in the dry hobbing process, the line speed of the high-speed steel hob of the coating (TiAlN) is required It can reach 180m/min or even higher; the linear speed of the hard alloy steel hob is required to reach 300 m/min. In order to realize this kind of high-speed hobbing processing, the tool spindle can generally be realized by an electric spindle; for the worktable, a newly designed gear transmission system with automatic clearance elimination is used to replace the traditional worm and worm gear transmission system, LIEBHERR, GLEASON The worktables of high-speed gear hobbing machines of other companies have adopted torque servo motor technology, and the worktable speed can reach more than 800 r/min. <br /> <strong>(2) </strong><strong>Quick separation of chips</strong><br /> Due to the high temperature, if the chips cannot be quickly separated from the tool, workpiece and machine tool, it will easily cause thermal deformation and affect Machining accuracy, so iron filings must be removed quickly and effectively. In dry hobbing, the high-speed hobbing of the hob is generally used to make the iron filings quickly leave the tool and the workpiece. Many companies have also put forward some machine tool structural improvements in response to the chip removal problem, such as using gravity to speed up the removal of iron filings, and avoiding the iron filings from directly falling on the workbench, and then assisting with high-pressure cold air to achieve rapid and effective chip removal. Some companies also use stainless steel heat shields. On the one hand, the surface of stainless steel is smooth, which facilitates the removal of iron filings. On the other hand, the heat conductivity of stainless steel is small, which reduces the heat transfer of iron filings to the workbench and bed. <br /> <strong>(3) </strong><strong>High-speed hob</strong><br /> The hob material for dry hobbing adopts cemented carbide steel in the early stage of development, but due to cemented carbide Steel hobs are expensive. The powder metallurgy high-speed steel hobs and TiAlN-coated high-speed steel hobs developed in recent years have a tendency to replace hard alloy steel hobs for dry hobbing. In a research report, Liebherr Company has performed the processing of hard alloy hob (Carbide) dry hob, powder metallurgy high-speed steel hob (HSS-PM) and conventional high-speed rigid hob (Conv.HSS). The time and processing cost are compared. Comparative analysis results show that, compared with conventional machining, dry hobbing has shorter processing time and lower cost; the use of powder metallurgy high-speed steel hobs even has better dry hobbing results than the use of cemented carbide steel hobs . <br />
