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.
