Common causes and solutions for abrasive belt fracture
Grinding and Polishing Solutions Common causes and solutions for belt breakage. In the daily and processing process, you will encounter many different problems about the abrasive belt, such as belt breakage, belt wrinkles, belt deviation, lateral vibration of the workpiece surface, surface burn of the workpiece, workpiece size error, etc. Detailed cause analysis and timely solutions for abrasive belt grinding and polishing solutions.
(1) The belt joint is not strong and cracked.
Solution: Strengthen quality control in production to meet user needs
(2) The cutting is too deep and the friction heat accumulates.
Solution: Reduce cutting depth or feed rate, or use coolant or cooling
(3) Working pressure is too large. Grinding polishing solution
Solution: reduce the pressure
(4) Wrinkles or edge damage of the belt during transportation or installation.
Solution: Appearance quality check before installation, correct operation when installed
(5) The abrasive belt tension is too large.
Solution: Adjust the tension, do not slip under the workload, the tension is as small as possible
(6) External debris enters between the belt and the roller or plate.
Solution: Remove debris, high-efficiency dust is the best preventive measure
(7) The contact roller is tapered; the contact roller or graphite pad is not parallel to the base.
Solution: Grind the roller to remove the cone; reinstall and keep parallel
(8) The thickness difference of the workpiece is too large or partially overlaps the impact belt.
Solution: Install guards for overlapping plates and oversized parts
(9) The machine is not working properly, the belt is broken by the travel switch
Solution: repair equipment (special attention to paper-based abrasive belt)
(10) excessive vibration of the belt
Grinding and Polishing Solution: Use a low-hardness contact wheel to check the vibration of the machine or the quality of the belt.
