Research on the Reason of Uneven Abrasion on the Works Layer of the Impregnated Diamond Bit

Abstract:

Main reason of uneven abrasion on the work layer of impregnated diamond bit is proved through theoretical analysis and application test. Adopting rectangle water mouth makes diamond cutting burden heavier along radius line from outside to inside and causes the rapid abrasion to works layer when diamonds in bit are distributed evenly and in the same quality.
