Tungsten cemented carbide ball blank

Cemented carbide ball grade information as follows:

There are three types of cemented carbide balls, one is carbide ball blank also called as unground carbide ball, Thos balls are made without any processing after sintering, and the surface is rough and cannot be directly used to make precision machinery or precision instruments. Besides, there are also 2 different carbide ball blank, one is carbide ball with a band around it, another is without band around it. As you can see follow pidctures. The second is carbide ball after general ball milling, and its surface finish is higher than that of carbide ball blank, which can be used to make mechanical equipment, instruments and valve bodies with low requirements. The third is to polish carbide ball. The polished tungsten cemented carbide ball undergoes three processes of rough grinding, fine grinding and polishing, and its surface roughness reaches a mirror effect. It can be used to make precision machinery, instruments, and meters that require high precision matching. With high hardness and high processing cost, its application range is limited to high-end, high-quality precision equipment.

Production process of tungsten cemented carbide ball blanks

Pulverizing → formula according to application requirements → wet milling → mixing → pulverizing → drying → sieving → adding forming agent → re-drying → sieving to obtain a mixture → granulating → cold isostatic pressing(CIP) → forming → sintering → Forming (blank) → packaging →storage
