How to choose the correct cutting disc

The high-speed low price disc for metal (hereinafter referred to as the cutting piece) is widely used in many industries because of its 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.

First, the occasion of the use of cutting pieces
First, it is selected according to the occasion in which the dicing sheet is used. The 5 inch resin cutting disc for metal 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.
Second, the choice of the cutting blade of the ordinary cutting machine
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, due to the small cutting power in order to reduce the radial frictional resistance, we usually choose a cutting piece with a thickness of 3.2 mm. The cut piece is thinner and has a certain elasticity, and it feels sharper when cut. In order to reduce the lateral frictional resistance, Sanxiong Abrasives has changed the surface contact into point contact, and the formulation system has added lubricant, which can greatly reduce the friction heat generated during cutting and improve the durability and sharpness of the cutting piece.
Third, 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 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.
