孕镶金刚石钻头工作层不均匀磨损原因的研究

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

摘要:

通过理论分析和生产试验，论证了孕镶金刚石钻头工作层高度磨损不均的主要原因是：在金刚石等浓度分布和质量相同的情况下，因采用矩形水口使得唇面金刚石沿半径线由外向内切削工作负担逐渐加重所致。提出了改善措施。

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.
