Abstract

The invention discloses a formula of a cutting piece for titanium alloy. The formula comprises, by weight, 46%-60% of 46 mesh monocrystalline fused alumina, 10%-20% of 60 mesh iridium-plated white fused alumina, 2.0%-8.0% of 150 mesh-180 mesh green silicon carbide, 4.5%-7.5% of 1800 mPa.s-2000 mPa.s liquid phenolic resin (25 DEG C), 9.0%-15.0% of 200 mesh-300 mesh powdery phenolic resin, 5.0%-15.0% of 325 mesh-400 mesh potassium fluoroaluminate and 0.2%-0.8% of 325 mesh-400 mesh carbon black. The formula has the advantages that by the adoption of the formula with several materials mixed in use, the special resin grinding wheel cutting piece for the titanium alloy is manufactured through a specific hot-pressing technology and can meet the requirement for efficiently cutting titanium alloy workpieces; in the cutting process, the product is smooth in feeding, free of blockage and good in heat dissipation and will not burn out the workpieces, cuts are narrow, section burrs are small, durability is improved by 4-5 times, the amount of dust is small, efficiency and safety performance are improved, and toughness and ageing resistance are remarkably improved.

Description
