CBN Inserts Machining Mud pump with better impact resistance than ceramic insert
1. Halnn Tools CBN Inserts Machining Mud pump with better impact resistance than ceramic insert
Normally the manufacturer will choose High chromium cast iron as the main materials of the industry pumps, but because of its high hardness of high chromium and the casting defects, the industry pump is difficult to machine. Common carbide insert and cbn insert both don't have good wear resistance. Choose the right cutting tools will be very important to improve the efficiency and lower the costs.
Nowadays, most industry pumps use high chromium cast iron as the main materials, which make the pumps more wear resistant than before. However the hardness of high chromium cast iron will be high and it also has some casting defects, In order to solve the problems, choosing the right cutting tools will be very important.
