Cutting piece selection and development trend

The cutting sheets are mainly classified into fiber resin cutting sheets and diamond cutting sheets according to materials.
1. Resin cutting piece is made of resin as bonding agent, glass fiber mesh piece as bone and bone, combined with various materials, especially for alloy steel, stainless steel and other difficult cutting materials, the cutting performance is particularly remarkable. Dry and wet cutting methods make the cutting precision more stable. At the same time, the choice of material and hardness of the 6 inch es cutting disc can greatly improve your cutting efficiency and save your production cost.
2, diamond cutting sheet is a cutting tool, widely used in stone, concrete, prefabricated panels, new and old roads, ceramics and other hard and brittle materials processing. The diamond cutting piece is mainly composed of two parts; the base body and the cutter head, the base body is the main support part of the bonding cutter head, and the cutter head is the part which is cut during use, and the cutter head is continuously consumed in use. The base is not, the reason why the cutter can cut is because it contains diamond, diamond is the hardest material at present, it rubs and cuts the object to be processed in the cutter head, and the diamond particles are wrapped in metal by the knife. Inside the head.
Where the cutting piece is used
First, it is selected according to the occasion in which the dicing sheet is used. The aluminum abrasive cutting disc can be divided into cutting and grinding according to the way of use. Most of the cutting machines are fixed mobile, and the power of the machine is divided into high power (>5.5KW) and low power (<3KW). Cutting speeds are also available in high speed cutting (>80m/s) and normal cutting. In addition, the materials to be cut during cutting are various, such as stainless steel, titanium alloy, ordinary steel, viscous metal, high carbon steel, non-metal, and the like. The performance requirements of the cutting piece are different for different occasions, so it is important to choose a reasonable cutting piece. We need to choose the cutting piece according to the occasion we use, which can increase the safety factor, improve work efficiency and reduce our use cost.
Selection of cutting blades for ordinary cutting machines
Ordinary cutting machines usually refer to fixed cutting machines, cutting machines with a power of High power cutting machine cutting blade selection
High-power cutting machines usually use a cutting power of more than 5.5 kW, a speed of 2800 rpm, and a large diameter of the cutting workpiece. Because the torque force during cutting is large, the damage to the cutting piece is also relatively large, so the cutting piece is required to have a certain rigidity. We usually use a 3.8 mm thick customized metal cutting disc. At the same time, due to the large cutting diameter, the resistance of the cutting piece will also increase, and the temperature of the cutting surface will be high, so it is very important to reduce the cutting temperature. If necessary, add water to cool when cutting. The experiment proves that if the water is cooled during cutting, the durability of the cutting piece can be improved by 1.5-2 times. However, in some occasions, there is no condition for water cooling. Therefore, when the high-power cutting piece is produced by Jixiang Abrasives, the powder coolant is added according to the formula to reduce the temperature generated during cutting, and the life of the cutting piece is improved.
