The dynamic balance state of the resin grinding wheel cutting disc is directly related to the safety of the cutting operation and the quality of the processed surface. The dynamic balance detection technology can effectively avoid potential risks and improve processing accuracy by accurately evaluating and correcting the balance performance of the cutting disc.
First of all, the core of the dynamic balance detection technology lies in accurately identifying the imbalance of the cutting disc. During the manufacturing process of the resin grinding wheel cutting disc, the center of gravity will deviate from the center of rotation due to factors such as uneven distribution of abrasives, differences in resin curing shrinkage, or shape processing errors. The dynamic balance detection equipment uses sensors to collect vibration data in real time by rotating the cutting disc at high speed, analyzes the vibration amplitude and phase, and thus determines the size and position of the imbalance. For example, when the cutting disc is eccentric, periodic centrifugal force will be generated during high-speed rotation, causing vibration. The vibration signal captured by the sensor can be quantified after algorithm processing, providing data support for subsequent correction. Accurate identification of the imbalance is the prerequisite for ensuring cutting safety and quality. If it is not detected in time, the eccentric cutting disc is prone to cause violent vibration when running at high speed, and even causes the cutting disc to break, threatening the safety of the operator.
Secondly, the dynamic balance detection results directly affect the stability and safety of the cutting process. When an unbalanced cutting disc is cutting, the periodic change of centrifugal force will cause the cutting equipment to vibrate, aggravate the wear of equipment components, and shorten the service life of the equipment. More seriously, strong vibration may cause local stress concentration in the cutting disc. When the stress exceeds the strength limit of the cutting disc, it will cause the cutting disc to break, and the high-speed flying fragments can easily cause casualties. Through dynamic balancing detection technology, the unbalanced cutting disc can be corrected, such as adding a counterweight block on the lighter side or removing some materials on the heavier side, which can effectively reduce centrifugal force and vibration. Studies have shown that the vibration amplitude of the cutting disc that has undergone strict dynamic balancing detection and correction can be reduced by more than 60%, significantly improving the safety of cutting operations and avoiding safety accidents caused by unbalanced cutting discs.
Furthermore, the dynamic balance state is closely related to the quality of the cutting surface. When the cutting disc is in an unbalanced state, the vibration during the cutting process will cause the cutting trajectory to deviate, causing defects such as wavy and jagged incisions, and greatly increasing the surface roughness. For example, in metal pipe cutting, unbalanced cutting discs will make the edges of the cuts uneven, affecting the quality of subsequent welding; when cutting stone, vibration will cause cracks on the cut surface, reducing the yield rate. The cutting discs that have undergone precise dynamic balancing detection and correction run smoothly and have uniform cutting force, which can ensure the accuracy of the cutting trajectory, effectively reduce defects such as burrs and ripples on the cuts, and make the cutting surface smoother. Experimental data show that a well-balanced cutting disc can reduce the Ra value of the cutting surface roughness by about 40%, significantly improve the cutting quality, and meet the needs of high-precision processing.
Then, advanced dynamic balancing detection technology can realize the hierarchical management and optimized use of cutting discs. By performing dynamic balancing detection on the cutting discs, they are divided into different grades according to the size of the imbalance, and are reasonably allocated for use according to different processing requirements. For high-precision cutting operations, cutting discs with high balancing accuracy are preferred to ensure cutting quality; for ordinary rough processing, cutting discs with slightly lower balancing accuracy but still within the safe range can be used to reduce production costs. In addition, dynamic balancing detection technology can also combine the number of times the cutting disc is used, the degree of wear and other information to establish a life prediction model, predict the performance attenuation trend of the cutting disc in advance, and replace it in time before the risk of imbalance increases, so as to avoid safety hazards and quality degradation caused by excessive use, and realize scientific management of the entire life cycle of the cutting disc.
Then, the application of the automated dynamic balancing detection system has greatly improved the detection efficiency and accuracy. The traditional manual balancing detection method relies on the experience of the operator, which is inefficient and has large errors. The modern automated dynamic balancing detection system integrates high-precision sensors, high-speed rotating devices and intelligent algorithms, which can complete the balance detection and correction of the cutting disc in a short time. For example, a servo motor is used to drive the cutting disc to rotate, and a laser displacement sensor is used to monitor the surface profile of the cutting disc in real time. The system automatically calculates the imbalance amount and controls the manipulator to complete the correction operation. The whole process only takes tens of seconds, and the detection accuracy can reach the micron level. The automated system can also be connected to the production management system to realize the automatic recording and analysis of the detection data, provide a basis for the optimization of the production process, and promote the production of resin grinding wheel cutting disc to develop in the direction of intelligence and efficiency.
In addition, the continuous innovation of dynamic balancing detection technology has brought new breakthroughs to the cutting process. In recent years, dynamic balance pre-assessment technology based on virtual simulation has gradually emerged. By building a three-dimensional model of the cutting disc, simulating its dynamic characteristics under different working conditions, predicting possible imbalance problems in advance, and optimizing the design scheme. For example, in the design stage of the cutting disc, finite element analysis software is used to simulate the shrinkage deformation during the resin curing process, adjust the abrasive distribution and structural parameters, and reduce the generation of imbalance from the source. At the same time, non-contact dynamic balance detection technology is also constantly developing. For example, the electromagnetic induction principle is used to complete the balance detection without direct contact with the cutting disc, avoiding the damage to the surface of the cutting disc caused by traditional contact detection, and further improving the reliability of the detection and the yield rate of the cutting disc.
Finally, strengthening the standardization and normalization of dynamic balance detection technology is an inevitable requirement for the development of the industry. At present, there are differences in the dynamic balance detection standards and methods adopted by different companies, resulting in uneven quality of cutting discs. Establishing a unified dynamic balance detection standard and standardizing the technical parameters, operating procedures and balance accuracy level of the detection equipment will help improve the overall quality level of the industry. For example, formulate the corresponding relationship standard between the balance accuracy of cutting discs and the rotation speed and diameter, and clarify the allowable unbalance threshold of different types of cutting discs, so that enterprises can have a basis for production and testing. At the same time, strengthen the professional training of testing personnel, improve their understanding and operation ability of dynamic balance testing technology, ensure the accuracy and consistency of test results, so as to provide solid guarantee for the safety and high quality of cutting operations, and promote the healthy and sustainable development of the resin grinding wheel cutting disc industry.
