Suitable For TCT Circular Saw Blades Substrate
We usually use carbide-tungsten carbide insert circular saw blades, TCT circular saw blades for short. As a carbide cutting tool cemented carbide saw blades are specially made for cutting and grooving metal materials. They are the most commonly used cutting tools in wood product processing. The quality of carbide saw blades is closely related to the quality of processed products. Correct and reasonable selection of carbide saw blades is of great significance for improving product quality, shortening the processing cycle, and reducing processing costs.
The base materials suitable for carbide circular saw blades are: 65Mn, 50Mn2V, SK5, SKS51, 75Cr1, etc. The welding materials mainly include silver welding wire and silver welding pieces. The middle layer of the silver welding piece is copper, and the two sides are silver, so it is called a "sandwich" welding piece, which mainly plays the role of eliminating welding stress and slowing down cutting impact. The blades of electronic saws are usually welded by silver soldering blades.
The quality of cemented carbide circular saw blades depends on the basic steel plate material, hardened saw blade material, suitability of welding materials, and the fineness of the manufacturing process.
Common types of cemented carbide are tungsten* (code YG), tungsten titanium (code YT). Because tungsten* type cemented carbide has better impact resistance, it has been widely used in the wood processing industry. The commonly used model in wood processing is YG8-YG15. The number after YG indicates the percentage of *content. As the content increases, the impact toughness and bending strength of the alloy will increase, but the hardness and wear resistance will decrease. Choose according to the actual situation. This is also true when choosing extra long wood drill bit . Choose according to your actual situation. Don't blindly follow the crowd or choose arbitrarily, to avoid unnecessary waste or wrong purchase.www.jeejatools.com
The History Of Diamond Cup Grinding Wheels
Diamond cup grinding wheel is one of the diamond tools, although not many people have heard of it, but not many. But, do you know the source of diamonds?
In 1988, it was accidentally discovered that there were light gray diamond particles in a stone meteorite. The National Museum of Nature also discovered diamond crystals from iron meteorites on the Antarctic continent.
Since then, some scientists have accidentally discovered many very fine diamond powders in meteorites. After measurement, it can be judged that they are older than the solar system, which shows that the formation of these diamonds has nothing to do with the impact between meteorites or falling to the ground, that is, they are not produced by high temperature and high temperature. high temperature. high pressure.
Based on these unexpected discoveries, some scientists have proposed new bold hypotheses. They believe that all the diamonds we find in nature come from a red giant star that formed billions of years ago. The red giant star itself is formed during the destruction of the star, so the hydrogen and high temperature there are particularly conducive to the collection and concentration of carbon gas into diamonds.
Thousands of years later, when the red giant finally exploded into a supernova, an amazing number of diamonds formed in the universe. These diamonds participated in the evolution of the solar system, so traces can be found on the earth and meteorites. This is assuming that the diamond comes from heaven.
Since then, whether the diamond comes from the sky or the ground, we have never been clear, waiting for scientists to continue to answer our questions.
