Reasons for diamond grinding discs falling off

Diamond grinding discs are an essential tool in the construction and maintenance of floor surfaces, but the problem of these discs becoming dislodged during use can be a significant obstacle. Accidental detachment of a grinding disc from a flooring machine can disrupt operations and affect the quality of work. Understanding the cause of this problem is critical to ensuring a smooth and safe grinding process. Let’s delve into the potential causes of diamond disc peeling and explore ways to fix these problems.

Materials Matter: Understanding Toughness and Hardness 

The material composition of diamond grinding discs plays a vital role in their performance and durability. Toughness and hardness are the fundamental properties that determine the wear resistance of these brake discs. The balance between toughness and stiffness is critical. An imbalance of these properties during the manufacturing process may result in insufficient adhesion and subsequent disc displacement during use.

• Insufficient Toughness: If the material lacks sufficient toughness, the grinding disc may easily crack or separate from the backing during operation. This can cause premature brake disc failure and detachment, compromising its effectiveness in surface treatment applications.
• Insufficient hardness: Conversely, insufficient material hardness accelerates wear and reduces the adhesion between the grinding surface and the backing material, resulting in an increased risk of the disc becoming detached during use. Proper hardness is critical to maintaining the structural integrity and adhesion of the grinding disc under operating stresses.

Grinding Table Life: Operating Factors Affecting Durability 

The service life of diamond grinding discs is affected by a variety of operational and environmental factors, each of which can significantly affect its performance and connection to the flooring machine.

• Floor flatness and hardness: In environments where the surface is uneven or poorly prepared, such as a sand-covered floor or a cement screed floor that is not flat enough, the abrasive discs are more likely to come off. Changes in surface hardness can also affect the ability of the grinding wheel to maintain strong adhesion. This emphasizes the importance of surface preparation and evaluation before grinding operations.
• Grinder weight and speed: The weight and speed of the floor machine during operation will also affect the durability and adhesion of the grinding disc. Improper weight adjustment or excessive speed may subject the disc to undue stress, leading to compromised adhesion and potential detachment.
• Construction method and conditions: Construction method, whether wet or dry grinding, selection of appropriate grinding disc model, particle size and quantity, as well as cumulative grinding time, will affect the life and firm adhesion of the grinding disc. Adhering to recommended practices and selecting the appropriate brake disc for a specific construction process is critical to optimizing performance and minimizing disengagement issues.

Machine Speed: Finding the Optimal Operating Range 

One of the common causes of diamond grinding disc loss is the speed at which the grinder is operating. When the machine is run at too high a speed, it can cause the grinding disc to come off unexpectedly.

Effect of high speed: Operating the machine at too high a speed will cause the grinding disc to withstand excessive centrifugal force, causing the adhesion to weaken and fall off. Sudden release of the disc can cause potential damage to equipment, and work surfaces, and injury to nearby personnel.

Wear and Tear Issues: Ensuring Correct Compatibility and Installation 

Another common reason why diamond grinding discs come off has to do with the compatibility and installation of the abrasive components on the disc. When there is a mismatch between the grinding material and the disc, or incorrect installation methods are used, the adhesion and retention of the disc may be compromised, resulting in detachment during operation.

• Compatibility Issues: The connection between the abrasive and disc must be carefully evaluated to ensure a proper fit. Incompatibilities can lead to insufficient adhesion and detachment. This puts risks to the operator and jeopardizes the efficiency of the grinding process.
• Installation errors: Improper installation methods, such as using incompatible abrasives or failing to adequately secure abrasive components, can result in recurring shedding problems. Identifying and correcting these installation errors is critical to restoring the integrity and stability of the grinding plate.

Cause of Sticky Disk: The Adhesion of The Adhesive Board Becomes Poor

The bond between the grinding disc and the adhesive plate that mounts the grinding disc to the floor grinder is critical for a safe and stable connection. Over time, adhesive plates can deteriorate, lose their adhesive power, and become susceptible to damage, increasing the likelihood that the grinding disc will fall off during operation.

Replace adhesive plates or fasteners: To combat this problem, regular inspection and maintenance of your adhesive boards is essential to identify signs of wear and deterioration. When the adhesive plate shows signs of reduced adhesion or damage, it needs to be replaced immediately to ensure a secure connection to the grinding disc.

Operational Issues: Operation Misuse and Uneven Chassis 

Improper use of the floor machine and uneven chassis will lead to uneven impact on the diamond grinding disc during operation. When some areas of the grinding plate receive excessive impact and other areas receive minimal force, the imbalance can cause the grinding plate to detach or unexpectedly eject, creating a safety hazard and possibly damaging the work surface. Operational issues require comprehensive training of flooring machine operators to ensure proper handling and use protocols are followed. Additionally, regular inspection and maintenance of the machine chassis is essential to address and correct unevenness and balance.

The Meaning of Cleaning the Diamond Grinding Discs 

Failure to clean the diamond grinding disc after each use may result in the accumulation of debris, dust, and particles. When new grinding discs are installed on floor grinders without adequate cleaning, the presence of residual debris such as gravel and hardened concrete can compromise the integrity and stability of the grinding disc attachment. This accumulation creates uneven pressure distribution, ultimately leading to potential separation during operation. To prevent the diamond grinding disc from falling off due to an unclean surface, we must establish a systematic cleaning procedure after each grinding process.
