Cutting disc are widely used in many industries because of their high performance, convenience, economy and other unique properties. However, many people have neglected to make reasonable choices of cut pieces according to the occasions they use. Today, Yihong abrasives will share with you the experience of the correct selection and use of some cutting blades.

Where the cutting disc is used

Choose different cutting disc for different occasions. The 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. . 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 wheel for ordinary cutting machines

Ordinary cutting machines usually refer to fixed cutting machines, cutting machines with a power of <3 kW and a rotational speed of 2900 rpm. Ordinary cutters typically cut workpieces that are less than 50 mm in diameter. However, since the cutting power is small in order to reduce the radial frictional resistance, we usually choose a cutting disc with a thickness of 3.2 mm. The cut disc is thinner and has a certain elasticity, and it feels sharper when cut. In order to reduce the lateral frictional resistance, the Yihong abrasives product changes the surface contact into point contact, and the formulation system adds lubricant, which can greatly reduce the friction heat generated during cutting and improve the durability and sharpness of the cutting blade.

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 cutting piece. 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 possible, 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 cases, there is no condition for water cooling. Therefore, when the high-power cutting piece is produced, the holy-grinding tool will add a powder coolant according to the formula to reduce the temperature generated during cutting, and improve the service life of the cutting piece.
