Cutting wheels and 3000 grit sanding disc are popular in different industrial sectors. During the use, the customer always encounters some damage to the 3000 grit sanding disc and cannot understand why it will be damaged on the 3000 grit sanding disc.
There are many types of damage to the cutting wheel and the 3000 grit sanding disc, but there are two main reasons for this:
1: improper operation of workers during use;
2: The quality of the cutting wheel and the 3000 grit sanding disc is not very good;
In order to enable each customer to become a specialized technical engineer during the use of the 3000 grit sanding disc, we will detail the detailed analysis of the common 3000 grit sanding disc damage for your inspection.
When the 3000 grit sanding disc is damaged during use, the following steps should be taken to check the cause.
1: Check if the worker is not operating properly during use
2: Check if the correct 3000 grit sanding disc is selected for material grinding work.
3: Check the quality of the 3000 grit sanding disc by comparing it with another 3000 grit sanding disc.
It is well known that different manufacturers always provide different quality 3000 grit sanding discs according to the customer’s needs, so this article will show the 3000 grit sanding disc damage caused by operational errors during use.
Damage 1: Breaking at the center of the 3000 grit sanding disc
Breaking in the middle of the center of the 3000 grit sanding disc
Cause of damage
The grinding angle during use is too flat, or the workpiece is ground and polished using the center groove of the grinding disc.
Error operation analysis
Since the sharpening angle is too flat or polished by the central groove during operation, the last layer of the protective net is cut off by the burrs. Once the protective mesh breaks and a lateral force is applied, the central recess is separated.
Damage 2: The center 3000 grit sanding disc is depressed and encounters edge wear and excessive vibration

Cause of damage: The clamping system (flange) of the angle grinder is worn, the angle grinder is damaged or damaged, and the vibration is large.
Error operation analysis
During the working process, due to the vibration of the angle grinder during operation, the wear of the center recessed 3000 grit sanding disc is uneven. 90% of this phenomenon is caused by a failure of the clamping system or poor machine condition and too much vibration. Due to the defects of the clamping system, the down-pressure type center 3000 grit sanding disc has no stable circumferential rotation and vibration, so the sanding piece is irregularly worn and starts to be knocked to cause cracking.
Damage 3: excessive wear of the edge of the 3000 grit sanding disc, layering of the fiberglass mesh
3000 grit sanding disc damage
Cause of damage: The angle of the 3000 grit sanding disc is too flat during the grinding process.
Error operation analysis:
After repeated use of the lower-pressure center 3000 grit sanding disc, excessive wear and large pieces of debris flew out, damaging the angle grinder. The reason is that the angle of the 3000 grit sanding disc is too flat during the grinding process. In general, the recessed center wheel should be used at a strong angle of at least 10 degrees. If the angle is less than 10 degrees, the last layer of the protection net will be damaged. In order to ensure the lateral force of the flap wheel sanding disc, we always use at least two layers of reinforced protective glass fiber mesh in Luoyang Juma Abrasive Co., Ltd. to manufacture the low concave center 3000 grit sanding disc.
Damage 4: excessive wear in the middle of the flat cutting wheel
Excessive wear in the middle of the cutting wheel
Cause of damage
The angle of the angle grinder is incorrect.
Error operation analysis:
The operator selects the maximum limit of the machine used to cut the steel, resulting in a strong lateral force on the clamping flange of the cutting blade. At the same time, the flange is also worn. The angle of the angle grinder flange used by the customer is 35 mm, but the standard outer diameter of the new flange is 44 mm and the flange is worn. For these applications, we recommend using a special flange with an outer diameter of 76 mm.
Damage 5: When cutting superhard materials, the edges of the cutting wheel are excessively worn and not sharp.

Cutting wheel selection error
Error operation analysis
Black burns appear around the 3000 grit sanding disc.
The above applications are for 3000 grit sanding disc of high carbon steel, alloy steel and very hard materials. Black burns occur around the edges of the 3000 grit sanding disc as the customer selects the metal cutting wheel to cut these hard materials. Based on these applications, customers should choose high-performance cutting wheels to cut such hard materials.
Milling operation
The 3000 grit sanding disc is an integral part of the system and consists of a 3000 grit sanding disc, an angle grinding machine, working materials and operating factors. Every factor affects all other factors.
