Precision tool & Diamond tools and blades

1. Diamond grinding wheel  series: Artificial diamond, also known as "industrial diamond", is the hardest substance known to man in nature today, as is natural diamond. Due to its high hardness, compressive strength and wear resistance, acid and alkaline resistance, as well as good thermal conductivity and semiconductor properties, it is made into a variety of tools products can be widely used in metallurgy, machinery, geology, petroleum, electronics, optics, construction, stone and other fields. Artificial diamond grinding wheel is a kind of artificial diamond product made from artificial diamond and other metal powder through high temperature and pressure, which can be widely used in the grinding of hard alloy, non-ferrous metal and non-metal. 2.Particle size to choose The size of synthetic diamond is indicated by its size number. The size of the workpiece directly affects the surface roughness, grinding efficiency and tool loss. In principle, the choice of particle size is...

1. If the  diamond grinding wheel  is not used immediately, it should be put flat or hung up with the inner hole. Other articles or feet should not be piled on the flat saw blade. ​ 2. When the diamond grinding wheel is no longer sharp and the cutting surface is rough, it must be repolished in a timely manner. Grinding can not change the original Angle, and break the dynamic balance. 3. The inner diameter correction and hole positioning processing of diamond grinding wheel must be carried out by the factory. If the processing is not good, will affect the product use effect, and may occur danger, reaming The upper aperture should not exceed 20mm, so as not to affect the balance of stress. 4. Selection of alloy grinding wheel. 1)  Resin bonded diamond grinding wheel  has a weak binding strength, so its self-sharpening performance is good enough, and it is not easy to block, high grinding efficiency, low grinding force and low grinding temperature. ...

The common tool materials in the tool grinding include high-speed steel (HSS), powder metallurgy high-speed steel (PM-HSS), hard alloy (HM), PCD, CBN, cermet and  other super-hard materials . The high-speed steel tool is sharp, the toughness is good, the hardness of the hard alloy tool is high, and the toughness is poor. The density of the hard alloy cutter is obviously higher than that of the high-speed steel tool. The two materials are the main materials of the drill, the reamer, the hammer and the tap. The performance of the powder metallurgy high-speed steel is between the two materials, and is mainly used for manufacturing the rough cutting knife and the tap. The high-speed steel cutter is not sensitive to the impact because of the good toughness of the material. But the hardness of the hard alloy tool is high and brittle, is sensitive to the collision, and the cutting edge is easy to jump. Therefore, during the grinding process, it is necessary to care for the operation ...

The super-hard material CBN invention can be used as an abrasive for the manufacture of a grinding wheel, which not only can effectively process the harder steel (HRc 45-65), but also improves the durability of the grinding wheel by a plurality of times. In particular, in the mid-1980s, the research and development of the CBN grinding wheel of the ceramic bonding agent, in particular the technical breakthrough in the correction of the sharp, can be said to be a revolution of the grinding mold in the mid-1980s, in particular by the German Krebs & Riedel. Classification of CBN Grinding Wheel The grinding wheel made of CBN grinding material can be divided into the following four kinds according to different processing technology and the binding agent of different components used. Their properties and uses (refer to the use of machining) are also different. (1) Electroplated CBN/ diamond grinding wheel The production process of the grinding wheel is simple, and the production ...
