Cutting wheels are widely used in many industries because of their unique properties such as high efficiency, trouble-saving, and economy. But many people neglect to make a reasonable choice of cutting wheels based on the occasion of use. Based on so many years of experience in the social production and sales of cutting wheels, our company will share with you the experience in the selection and use of some cutting wheels.
1. Suitable occasions for cutting wheels
Choose according to the different occasions where the cutting disc is used. Cutting wheels should be divided into cutting and wiping in terms of the way they are used. Most of the cutting machines are of the real estate transfer type, and the description of the speed of the work of the machine can be divided into the speed of the large description of the work (>5.5KW) and the speed of the small description of the work (<3KW). There are also two types of cutting speed: fast cutting (>80m/s) and general cutting. In addition, there are many kinds of materials to be cut during cutting, such as stainless steel, titanium alloy, ordinary steel, sticky metal, high carbon steel, non-metal, etc. Different service occasions have different performance requirements for cutting discs, so it is very important to choose cutting discs reasonably. We have to choose cutting discs according to the occasions we use, which can increase the safety factor, improve labor production efficiency, and reduce our operating costs.
2. Cutting wheel - the choice of the cutting wheel of the general cutting machine when it is used
The general cutting machine often refers to a cutting machine with a real estate cutting table, a description of the speed of work <3KW, and a speed of 2900 rpm. Common cutting machines often cut workpieces with a diameter of less than 50mm. However, because the speed of work performed by cutting means is small and the radial friction resistance is out, at this time we often choose cutting wheels with a thickness of 3.2mm. Such a cutting wheel is thinner and has a certain degree of elasticity, and it will feel sharper when cutting. In order to eliminate the lateral friction resistance of our products, the surface contact is changed into a point contact, and the trim system is added with a smoothing agent, which can greatly reduce the friction heat of new things during cutting and raise the cutting blade not easy to use damage and sharpness.
3. The selection of the cutting wheels of the fast and slow cutting machine with a large description of work
The fast and slow cutting machine with large description work often uses the cutting table to describe the speed of work greater than 5.5KW, the speed reaches 2800 rpm, and the occasions where the diameter of the cut workpiece is large. The reason is that the torque force is relatively large when cutting, and the carbide rotary file is also relatively harmful to the cut-off piece, so it is suggested that the cutting wheel must have a certain rigidity, and we often use a cutting wheel with a thickness of 3.8mm. At the same time, due to the large cutting diameter, the resistance of the cutting wheel will also increase, and the temperature of new matter on the cutting surface will be very high, so it is very important to lower the cutting temperature. If conditions permit, add water to lower the temperature when cutting.
Scientific research shows that it is true: if the temperature of the water is lowered during cutting, it should increase the durability of the cutting disc by 1.5-2 times. However, some occasions unconditionally add water to lower the temperature, so when our company produces fast and slow cutting wheels with large descriptions for the society, it will be added to the powder temperature lowering agent according to the balance to benefit the cutting. service life.
