Material composition

1. Abrasive Grains——The cutting and grinding material

The correct materials should be selected according to the specific application

2. FIber Nets——The structural strengthening material

The appropriate mesh and gram weight should be selected according to the use and size of the product

3. Phenolic Resin——The bonding course

Phenolic resin with corresponding code should be selected according to the product use

4. Label——Appearance and trademark materials

Should be based on different markets, and customer requirements, select the corresponding form

5. Iron Sulfide——Cooling, lubricating material

Absorb oxygen reaction, reduce the oxidation of resin, improve high temperature performance. 650 degrees absorb heat and decomposition reaction occurs, reducing the working temperature of the grinding wheel. At about 1100 degrees, it enters a molten state and becomes a good lubricant to protect the grinding wheel.

6. Cryolite——Auxiliary structure reinforcement, auxiliary cutting and grinding, manufacturing air holes, help to melt the workpiece

It has good affinity with phenolic resin and can be evenly distributed in the resin binder. High strength, good crystal shape, can play the role of auxiliary cutting. Crystallite melts at 1000 degrees, promoting the abrasive grains shedding, increasing self-sharpening, and creating pores to increase heat dissipation.

7. Gypsum Powder——Structural reinforcing material

It mainly plays the role of support to fill the gap between abrasive particles and auxiliary materials. Reduce resin shrinkage, improve rheological properties, control viscosity

8. Color Material——Appearance materials

To improve the appearance of products, appropriate forms should be selected according to market and customer needs

Inspection item

1. Grinding test

Routine cutting test is used only for longitudinal comparison of stability between different batches. To check whether the product meets the market requirements, you need to simulate the actual operation scenario for horizontal comparison test.

2. Appearance detection

Whether the outside diameter, inside diameter, thickness is up to standard, appearance is defective. Whether the fiberglass mesh is flat, fit aThe outside diameter, inside diameter, thickness and other dimensions meet the standard, and the appearance is defective. Whether the fiberglass mesh is flat, fit and tight.

3. Identification parameter check

Whether the metric size is converted correctly, the speed is marked correctly, and the specification parameters are consistent with the product.

4. Basic production process control inspection

Whether the mixture is adjusted according to the weather and whether it is properly wet and dry. Whether the mold is regularly replaced and maintained, whether the scraper is regularly trimmed, and whether the static balance test of the product meets the standard. Check for completeness of each batch daily. Whether the temperature in the furnace is calibrated.

FLAP DISC

The correct materials should be selected according to the specific application

2. Backing——The structural strengthening material

According to the product use and size, select the appropriate material, layer number, each layer configuration, size

3. Glue——The bonding course

The appropriate code and amount of glue should be selected according to the product use

4.Label——Appearance and trademark materials

Should be based on the size of the back base and customer requirements, select the corresponding form

Inspection item

1. Grinding test

2. Appearance detection

Flap size meets the set standards. Check whether the flaps are even from front and back. Whether there is glue on the flaps, whether the glue is out of the inner circle and outer circle, and whether the position of glue is correct. Whether the backing is damaged or defective. Whether the label is pasted concentric. Whether the thickness of each piece is uniform.

3. Identification parameter check

Whether the metric size is converted correctly, the speed is marked correctly, and the specification parameters are consistent with the product.
