Factors Affecting The Cutting Speed Of The Cutting Disc
The cutting speed of the cutting piece is the feeding speed of the sawed stone. Its speed affects the sawing rate, the force of the saw blade and the heat dissipation of the sawing area. Its value should be selected according to the nature of the sawed stone. The sawing of the fine-grained, relatively homogeneous granite can increase the feed speed appropriately. If the feed speed is too low, the diamond blade is easily soothed. However, when sawing a coarse-grained structure with uneven hardness, the cutting speed of theChina cutting disc for metalshould be reduced. Otherwise, the saw blade vibrates and the diamond is broken and the sawing rate is lowered. The cutting speed of sawing granite is generally selected within the range of 9m~12m/min.
The cutting disc is generally a diamond cutting disc. There are two kinds of diamond cutting disc to choose from. They use different abrasive grain adhesives – one cutting disc is made of metal adhesive and the other is made of a phenolic plastic adhesive. Both cutting blades can be used for cutting very hard materials. Metallic binders are suitable for materials with higher brittleness, such as ceramics and phenolic binders, which are suitable for cutting materials similar to cemented carbide. CBN cutting wheels are available in phenolic plastics only and are suitable for cutting very hard ferrous materials such as white cast iron.
Hard-cut sheets have better abrasive retention than soft cuts. The soft-cut piece is used to cut hard and brittle materials, because it will continue to replenish new and sharp abrasive grains with soft and tough materials as the lower hardness adhesive decomposes. An aluminum flat cutting disc with higher hardness.
The diamond cutting disc production process
1. Sintered diamond cutting disc: divided into cold pressing sintering and hot pressing sintering, which are pressed and sintered.
2. Welded diamond cutting disc: divided into high-frequency welding and laser welding. The high-frequency welding welds the cutter head and the base body through a high-temperature melting medium. The laser welding melts the contact edge of the cutter head and the base by a high-temperature laser beam to form a metallurgical bond. .
3. Electroplated diamond cutting disc: The cutting head powder is attached to the substrate by electroplating.
