Analyze lose efficiency problem from the production technology

　　If bucket tooth pin manufacturer decide to solve the earlier lose efficiency problem from the production technology, they need to pick two samples from the front working surface and back working surface first, use the grinding machine to grind them with a smooth degree then testing their hardness degree. The professional bucket tooth pin manufacturer attention if there exist a big hardness degree tolerance on one same sample, we can preliminary confirm the earlier lose efficiency problem caused by the raw materials is not very uniform.

　　The bucket tooth pin manufacturer attention if they had provide the grinding, polishing and corrosion tests on same sample, but find there exist a obvious boundary lines happened on each samples, but the happen positions are different, the color from the surroundings is light gray color, but the color for center part is darkness color, bucket tooth pin manufacturer said we can confirm this bucket teeth pin belongs to the casting working piece.
