Boost knowledge! CBN grinding wheel synthesis guide

The entire process of grinding wheel forming involves mixing abrasive and adhesive into a mold to evenly distribute the fabric. Then, the equipment is operated to press down. When the pressure reaches the predetermined value, it is maintained for a certain period of time, and then the pressure is discharged and returned. The ejection cylinder pushes out the finished product. Grinding wheel processing can be divided into two methods. One is the hot pressing method, which is to press and sinter abrasives using hot pressing. This method is suitable for small grinding wheels, requires small equipment tonnage, has good accuracy in producing grinding wheels, high strength, and durability; The second method is cold pressing, which is to press the abrasive into shape by cold pressing, and then sinter it to make it. This method is simple to make, has a long mold life, a short mass production cycle time, high work efficiency, and low production cost. It is suitable for processing large and medium-sized grinding wheels, and requires a large tonnage of equipment.

1. Ingredients: Weigh the various raw materials required according to the mixing method.

2. Mixing: The entire process of mixing abrasives and other types of materials according to process standards in order and time requirements into formed materials.

3. Forming: The process of using a grinding wheel forming hydraulic press and mold to press the formed material into the desired shape of the grinding wheel blank.

4. Drying: It can be divided into natural drying in a natural environment, artificial drying using artificial heating methods, and continuous drying using both.

5. Sintering: In this process, the ceramic grinding wheel is called sintering; Resin grinding wheel is called hardening; Rubber grinding wheel is called vulcanization. The entire process is considered successfully completed by temperature changes of heating, constant temperature, and cooling.

6. Processing: Use a lathe or grinder to process the outer circle, plane, and aperture of the burned embryo into a finished product, and some even require drilling, sulfur infiltration, wax infiltration, and so on.

7. Inspection and stamping: A comprehensive inspection should be conducted on the appearance, size, hardness, balance, strength, etc. of the product to ensure that it meets the specified requirements, and standard seals should be affixed to those that meet the standards,

Print out the product qualification certificate.

8. Packaging and storage: Packaging those that meet the standards according to the requirements, and then storing them in the warehouse.
