How To Judge Diamond Grinding Wheel Good? Judge Good Or Bad Standards!

Diamond grinding wheel is also of good quality, so we need to carefully select, but many people do not know how to judge the diamond grinding wheel is good, which requires us to learn some professional selection skills.
Method of judging the quality of diamond grinding wheel: 1. Do not appear dumb sound when the diamond grinding wheel is beating. The method of listening is often used to judge, which means knocking the grinding wheel. If the mute sound comes out, it indicates that there may be hidden cracks in the internal structure of the grinding wheel or in the connection between the diamond layer and the transition layer, or between the suppression layer and the foundation. 2. Sometimes the balance of some thick grinding wheels is in line with the requirements, but dynamic unbalance may occur. Therefore, for thin and thick diamond grinding wheels, large aperture and combined type diamond grinding wheels, action balance inspection must be carried out; The dynamic balance check of grinding wheel is generally carried out in a special balancing machine. After the use of balancing machine to measure the instability of each part of the grinding wheel unbalance, you can use the method of drilling weight symptom aggravation method to calibrate, but more holes can not be more than three. 3. Safety inspection shall be carried out on diameter, thickness, diameter, diamond layer thickness, total width of diamond grinding wheel, Angle of view, inclination of various special-shaped grinding wheels and dimensional tolerance of diamond grinding wheel; The diameter, thickness, diameter, diamond layer thickness and total width of diamond grinding wheel are all measured with vernier caliper with precision of 0.02mm, and the diameter is also accurately measured with screw plug gauge, inner diameter meter or inner diameter micrometer.

 

Criteria for judging the quality of diamond grinding wheel: 1. First, people who do not understand the trend will feel that the beautiful surface of diamond grinding wheel is the key. In fact, this is not the case. It is neither reasonable nor recommended to judge the quality of grinding wheel according to the surface. Because a good diamond grinding wheel needs to go through a variety of technological processes and experiments to ensure the quality. 2. In addition, touching the grinding wheel gate with your hand is not sharp, but do not excessively highlight it, which is easy to harm the relative total area of the diamond grinding wheel. At the same time, you can also pay attention to the closed blade type. If the diamond grinding wheel particles are pulled out, it is necessary to care about the density. If the density is moderate, it means that the diamond grinding wheel is in line with the requirements.

 

When you buy, you can take a pen to beat the side of the diamond grinding wheel, and then feel and listen to the sound. If the sound is clear, its quality will be good. In addition to the grinding wheel wear-resistant material material, particle size distribution, strength and other aspects can also be taken into account. When we find the problem of uneven diamond grinding wheel in operation, we should correct it in time, if it is not good, we should replace it. After years of development trend, abrasive tools have already developed to a certain level. Now the production time of molds is constantly decreasing. In other aspects, molds need to be greatly strengthened in the level of efficiency and production efficiency.
