1. Wear protective glasses, masks, earplugs, gloves, dustproof clothing; 2. Never use the side of the resin cutting sheet; 3. The highest use cycle speed of the flat cutting disc on sale, the highest use of the number of revolutions; 4. Use the correct flange. No enhancement: 1/3 or more; there is enhancement: 1/4 or more; 5. Confirm that the standard cut off wheel for metal has no missing edges, no cracks, no cracks, etc. before use; 6. Before starting to use the ultra-thin resin cutting piece, please use it for one minute and then use it. When replacing the new type of standard cut off wheel for metal, please idle for 3 minutes before using it. 7. Store the resin cutting piece in a place where there is no direct sunlight, no moisture, and place it horizontally; 8. The fixed object is firmly fixed; 9. Use an angle grinder with a safety cover, a cutting machine with a safety cover; 10. If the inner diameter of the resin cutting piece is small and the device does not match, please do not change the hole diameter of the grinding wheel. Do a good job of the above safety protection measures to ensure the smooth progress of high-efficiency production work. Nowadays, the use of standard cut off wheel for metal is becoming more and more extensive, and only when you have more relevant common sense can you use them better. First, if the tangential line is not straight or damaged, this is mainly due to improper diameter of the assembly flange, the assembly flange is not working well, the machine is not working properly; or the workpiece is improperly clamped, the cutting pressure is too large, the slice is too Caused by thin. Second, the inner diameter is damaged. The main cause of this phenomenon is improper assembly. The standard cut off wheel for metal is used as a grinding disc and the flange is partially lost. Third, if the wear is large, this is mainly caused by the machine speed is too large and the peripheral speed is too fast. In addition to this reason, it is necessary to note that if the cut surface is white, the slice is too soft. If the cut surface is discolored, the degree of consolidation is too hard. Fourth, the main cause of discoloration of the cut surface is that the slice is too hard, and the cross-sectional area of the object to be cut is larger than the slice diameter. There is also a result of long cutting time and low motor power. Fifth, the rim tear and this phenomenon are mainly caused by the use of the cutting piece as a grinding piece, that is, caused by improper use. Or the workpiece is caught by the spring due to improper operation of the machine.
