To ensure the quality of grinding wheel production, high-quality raw materials, bonding agents and advanced production processes must be used. At the same time, we should also pay attention to the production process and the quality of workers. Only when many aspects of the problem have been paid attention to, in order to produce high-quality grinding wheels.
2, grinding wheel quality inspection
1. Storage of grinding wheel
2. Transportation of grinding wheel
(1) The grinding wheel must be completely packed and transported and avoid collision, shall not be exposed to moisture for a long time, and shall not be in contact with alkali;
(2), the grinding wheel is stacked neatly in a flat way, and can not be tilted and pressured for a long time to prevent deformation;
(3) Avoid direct contact with the ground, must be stacked with wood pallet with tide, 10-15cm above the ground is appropriate, stacking height does not exceed 1 meter;
(4) Implement the first-in-first-use principle to ensure the best use period of the product;
(5) The product should be retested for rotary strength and appearance for more than one year before it can be used.
1. Rupture caused by grinding wheel cracking
Problem 1: When the grinding wheel hole is small or the shaft is large, it is hard to load
Problem 2: Use flanges on one side
Problem 3: Uneven support of the flange (flange bending; Lead hole layer protrudes; Flange burr; Uneven grinding wheel surface)
Problem 5: When a gasket is needed, there is no gasket or the gasket is too thin after the diameter is small
Problem 6: There is no groove on the inside surface of the flange or its diameter is small
2. The linear speed of the grinding wheel is too large
3. The workpiece is stuck between the workpiece support and the grinding wheel
Problem 1: The workpiece support is not properly adjusted
Solution: The interval between the workpiece support and the grinding wheel working surface is less than 3mm
Problem 2: Firmly load the workpiece between the workpiece support and the grinding wheel
Problem 3: When the side grinding is carried out without setting up the side grinding workpiece frame
4, the inspection of the grinding machine is insufficient or the machine tool is inappropriate
Problem 1: The bearing is loose, the spindle is bent, and the accuracy of the grinding machine is significantly reduced
Problem 2: The shaft diameter of the sand wheel shaft is too small
Problem 3: Rough grinding or the wrong method of using the grinding wheel
5. When the unbalance of the grinding wheel is too large
Problem 1: The balance check of the grinding wheel manufacturer is insufficient
Problem 2: The grinding wheel contains some water
6, grinding wheel strength is small
7. Spindle diameter and grinding wheel aperture are not suitable
8. Side grinding with inappropriate grinding wheel
9, the grinding wheel quality change
10, in the radius direction of the rupture into more than three occasions
11, the occasion of breaking into two pieces in the radius direction
Problem 1: The grinding wheel has cracks before use
Problem 2: Overuse the side of the grinding wheel
12. Irregular damage
