Need to pay attention to the purchase of the cutting piece
With the development of science and technology, our current technology is very powerful, and there are many new things in society. Then we are also a product that can not be separated from our society, then there are many sales and cutting on the market. The manufacturer of the film,
Ordinary cutting machines usually refer to fixed cutting machines, cutting machines with power <3KW and rotation speed of 2900 rpm. Ordinary cutting machines usually cut workpieces with a diameter less than 50mm. However, due to the small cutting power in order to reduce the radial frictional resistance, this When we usually choose a cutting piece with a thickness of 3.2mm, the thin flat cutting disc is thinner and has a certain elasticity, and it will feel sharper when cutting. Sanxiong Abrasives Co., Ltd. changes the surface contact into point contact in order to reduce the lateral frictional resistance. And the formulation system incorporates a lubricant, which can greatly reduce the frictional heat generated during cutting and improve the durability and sharpness of the cutting blade. High-power cutting machines usually use a cutting power of more than 5.5KW and a rotational speed of 2800 rpm. When the diameter of the cutting workpiece is large, the torque is large when cutting, and the damage to the cutting piece is relatively large. Therefore, the cutting piece is required to have a certain rigidity. We usually use a cutting piece with a thickness of 3.8 mm. Large, the cutting piece will also increase the resistance, the cutting surface will produce a high temperature, so it is very important to reduce the cutting temperature. If there are conditions, the cutting should be added Cooling experiments show that: the cooling water was added durability can be improved cut sheet cut if 1.5-2.
The grinding wheel does not know how deep it is to people in the present life, but what we have to know is that we are inseparable and use a wide range of comparisons in our lives.
The spark generated when the grinding wheel is working is very large, so it must be noted that it is burnt. Generally, the following matters should be noted when working on the grinding wheel:
First, there should be no flammable or explosive materials around; no polyester clothes, polyester is a by-product of petroleum, and it is flammable; do not wear short sleeves, but should wear long trousers. The grinding wheel is not The high temperature generated by the friction burns the contact part, but generates a sharp angle when rubbing, thereby cutting off the hard metal material. Those sparks are only the phenomenon after the sharp angle is generated, and the workpiece is not melted by the high temperature generated by the friction.

The cutting piece should be familiar to many of us because it will be used in the industry in our industry. In order to improve the slicing, the performance of the grinding wheel, the breakthrough of new technology and innovation, In fact, the grasp of each link and the details means the improvement of performance. It is conducive to improving efficiency. The 12 inches cut off wheel is made of resin as a bonding agent, combined with various materials, alloy steel, stainless steel, etc. Difficult to cut materials, cutting performance is particularly significant. Dry and wet cutting methods make the cutting accuracy more stable. At the same time, the choice of material and hardness of the cutting piece can greatly improve your cutting efficiency and save your production cost.
