    텅스텐 스틸 커터는 주로 텅스텐 강철 전체를 모재로 몇 가지 생산 공정을 거친 후 만들어진다. 경질합금이라고도 불리는 텅스텐강은 프리미엄 탄화텅스텐과 코발트분말을 제형비율로 혼합해 제압소결을 거쳐 만들어지며 고경도, 고강도, 고내마모성, 고탄성 모듈 등의 특징을 가지고 있어 분말야금 산업에 속한다.경질합금 공구는 현대공업의 발전을 추동하는 중요한 요소로 제조업의 발전에 기초적인 추진역할을 하고 있다.경질 합금 커터를 더 잘 활용하기 위해 사용하기 전에 연마할 수 있습니다.가장 좋은 연마 장비는. 텅스텐 스틸 커터 소개 텅스텐강은 결정립도별로 일반경질합금, 세결정경질합금, 아세결정경질합금, 초미세결정경질합금으로 나눌 수 있다.텅스텐강의 주요 화학성분에 따라 탄화텅스텐과 탄화티타늄으로 나눌 수 있다. Tungsten carbide includes tungsten cobalt class (YG), tungsten cobalt titanium class (YT) and added rare carbonization class (YW), which have their own advantages and disadvantages. The main components are tungsten carbide (WC), titanium carbide (Tic), niobium carbide (NBC) and other commonly used metal bonding phase is Co.Titanium carbide-based carbide is a hard alloy with Tic as the main component, and the metal bonding phase Mo and Ni are commonly used. The hard alloy has a high hardness (86 ~ 93HRA, equivalent to 69 ~ 81HRC), second only to diamond, good thermal hardness (up to 900 ~ 1000℃, maintain 60HRC).

  • PCD 공구를 이용한 연삭공정

    PCD 공구를 이용한 연삭공정The high hardness of PCD makes its material removal rate extremely low (even only 1/10000 of that of cemented carbide).At present, the PCD tool grinding process mainly USES the ceramic bonded diamond wheel for grinding. Because grinding between grinding wheel abrasive and PCD is the interaction between two materials with similar hardness, its grinding law is relatively complex. For high particle size and low speed grinding wheels, the use of water-soluble coolant can improve the grinding efficiency and grinding accuracy of PCD. The choice of grinding wheel binder depends on the type and processing conditions of the grinding machine. Because EDG grinding technology is hardly affected by the hardness of the workpiece being ground, EDG grinding PCD has great advantages. There is also a great demand for this flexible grinding process for the grinding of some complex shape PCD cutters such as woodworking cutters. With the continuous development of EDG grinding technology, EDG technology will become a major development direction of PCD grinding.Demina’s tool grinder Bt-150J is a diamond tool grinder with stable performance and simple operation, which is suitable for customers with low manual skills. Can manufacture and grind high-speed steel non-standard, hard alloy, polycrystalline synthetic diamond (PCD), and cubic boron nitride (CBN) and single-crystal cutting tools. Including welding turning tool, machine clip blade, boring tool, groove tool, and many other types, it is easy to grind out angles and arcs and other excessive edges on these tools.

  • PCD 도구 기능

    PCD 커터를 사용하여 알루미늄 합금을 가공할 때 다이아몬드의 경도가 높아 표면과 금속의 친화력이 낮고 커터의 전면 칼국수가 거울로 마감되어 적변이 잘 발생하지 않아 가공 치수 안정성과 표면 품질이 우수하다.PCD 커터를 이용해 각종 규격의 알루미늄 합금 부품을 가공하면 커터 수명이 수천에서 수만에 달해 특히 자동차·오토바이 부품의 대량 생산에 적합하다.PCD 도구의 주요 지표1.경질합금의 경도가 크고, 경질합금의 8~12배에 달하며, 최고 온도는 8000HV까지이다.2. PCD의 열전도계수는 경질합금의 1.5~9배인 최대 700W/mK까지 PCBN과 구리보다 높다.따라서 PCD 도구는 열전달 속도가 매우 빠릅니다.3. The friction coefficient of PCD is generally only 0.1 ~ 0.3 (the friction coefficient of cemented carbide is 0.4 ~ 1), so PCD tools can significantly reduce the cutting force.4. The thermal expansion coefficient of PCD is 1/5 of the cemented carbide, which is 0.9 × 10 ^ -6 ~ 1.18 × 10 ^ -6. Therefore, the thermal deformation of the PCD tool is small, and the processing accuracy is high.5. PCD 커터는 유색·비금속 소재와의 친화력이 적고 가공 과정에서 칩이 칼끝과 잘 결합하지 않아 컷팅종이 형성된다.
  • Cutting Process Of Honing

    The cutting process of honing The cutting process of honing is that the workpiece is fixed during honing. The honing head and the machine tool's spindle are floating and connected under a certain pressure through the relative movement of the honing head and the workpiece surface so that a very thin layer of metal is cut from the machining surface. During honing, the honing head has three movements, namely rotary motion, reciprocating motion and radial pressurizing motion perpendicular to the processing surface. The first two movements are the main movements of honing. Their synthesis makes the cutting trajectory of the abrasive grains on the stone on the surface of the hole intersect without reticulation, so it is easy to obtain a surface with a low surface coarseness. Radial pressurization is the feed motion of oilstone. The greater the pressure, the greater the feed. Main characteristics of honing Honing has the following main features 1. Honing is made of a softer material than the workpiece. During grinding, some abrasive particles are suspended between the workpiece and the grinding tool, and some abrasive particles are embedded in the surface layer of the grinding tool. The workpiece and the grinding tool are moved relative to each other, and the abrasive cuts a thin layer of metal on the workpiece surface mainly the bumps left by the previous process). 2. Manual grinding has a large workload and low productivity. The precision requirements of the are not high. Both metal and non-metal materials can be ground. 3. The grinding process of honing is not only processing metal with abrasive particles, but also chemical action. The abrasive mixture liquid forms an oxide layer on the surface of the workpiece, which makes it easy to be cut off by the abrasive, thereby greatly speeding up the grinding process. 4. The relative movement of the honing and the workpiece during grinding is more complicated. Therefore, each abrasive particle will not repeat its own trajectory on the workpiece surface, so it is possible to uniformly cut off the convex peaks on the workpiece surface. 5. Because honing is performed at low speed and low pressure, it is like that after grinding, the accuracy can reach IT6 or higher, and the surface roughness R. The value is less than 0.16 μm. But grinding cannot correct the position error of the hole, and the position accuracy of the hole can only be guaranteed by the previous process.
