The main varieties are coated abrasives-abrasive belts. It has become very important in improving production efficiency, upgrading products and beautifying people's lives. How to use abrasive belt to exert its excellent grinding performance, prolong its service life and improve the quality of working surface? \x0d\\x0d\ When opening a box of abrasive belt (especially when the width is 450mm): \ x0d \ \ x0d \- It should be hung one day before the machine is used to restore the abrasive belt to its natural shape, but it should not be hung for too long in wet season and in places with high temperature. \ x0d \ \ x0d \- Check the appearance quality of the abrasive belt before entering the machine. For example, whether there are defects, bumps and broken marks on the sand surface; Check whether the abrasive belt joint is smooth, whether there is opening phenomenon, and whether there is obvious protruding joint rubber block on the back of the joint; Whether the edge of abrasive belt is cracked; Whether the size of the printed surface of the trademark matches the size you need. For precision polishing, we recommend that you check the seam thickness of the abrasive belt. The inspection method is: measure the difference between the seam thickness of the abrasive belt and its own (non-seam) thickness with an outside micrometer, and the accuracy is 0~2.5mm and 0.01mm. We call this difference the seam thickness tolerance. The tolerance of joint thickness required by general accuracy should be less than 0. 10mm \ x0d \ \ x0d \- After the abrasive belt is installed on the machine, it should start running at a lower tension, and then gradually increase to the working tension after the abrasive belt runs smoothly. \ x0d \ \ x0d \- Choosing appropriate cutting parameters (cutting thickness) according to the material of the workpiece to be machined can also improve the service life of the abrasive belt. \ x0d \ \ x0d \- If you need to polish for many times, a reasonable grain size combination is the best way for you to obtain the ideal polishing effect. Take the three times sanding of MDF as an example: the abrasive belt is made of GXC5 1 (full resin silicon carbide abrasive belt), and the particle size is 1, P40-P80- 120 or 2, P60 (P50)-P100-P/KLOC. Among them, the joints of P 120 and P 150 abrasive belts are butt joints, and the effect will be better.
