The metal sintered abrasive sleeve is manufactured by uniformly mixing superhard abrasives (such as diamond or cubic boron nitride), metal powder, and binders in specific proportions, then pressing them into shape and sintering at high temperatures. After sintering, the product undergoes multiple stages of precision machining. The abrasive particles are uniformly distributed throughout the sintered body, forming a structure with multiple layers of abrasives. As the surface abrasives wear, new abrasive particles are gradually exposed, ensuring the tool maintains stable cutting performance and a high surface finish during use.

Features:

• Self-Sharpening Multi-Layer Structure
Abrasives are distributed throughout the tool body, ensuring continuous cutting performance as new grains are exposed.

• Extra Long Tool Life
Integral sintered structure with strong metal bond delivers exceptional durability and wear resistance.

• Stable & Consistent Honing
Maintains consistent bore size, geometry, and surface finish over long production runs.

• Ideal for High-Volume Production
Designed for continuous operation with reduced tool change frequency, improving efficiency.

Diameter range: 4.00 to 70.00 mm.

Application areas:
Hydraulic valves and valve bodies, distribution valves, Gears, ABS, brake cylinder, supercharger, rocker arms, connecting rod, parking pawls, crankcase, sprockets, powdered metal components, ceramic components.
