DOMILL offers a wide range of abrasive grains in various particle shapes, particle sizes and density for manufacturing organic abrasives such as resin bonded, rubber bonded and PVA abrasives to meet all of your requirements.
The resin bonded abrasive tools have a higher pressure strength, than the vitrified abrasives and a sufficient elasticity . The high stability of the bond allows the production of abrasive tools suitable for high speed cutting. They also are used to create abrasive chips in a variety of shapes and sizes for mass finishing. Resin abrasives are widely used across various machining processes such as rough grinding, coarse grinding, semi-fine grinding, precision grinding, honing, superfinishing, polishing, and cutting. They can process a wide range of engineering materials, including steel, aluminum, copper, iron, carbide, high-speed steel, titanium steel, stainless steel, wood, rubber, plastic, glass, ceramics, and stone.
The types of abrasive grains commonly used in resin bonded abrasives include:
Aluminum Oxide Series: Brown fused alumina (A), white fused alumina (WA), single crystal alumina (SA), microcrystalline alumina (MA), chromium alumina (PA), zirconia alumina (ZA), and black alumina (BA).
Silicon Carbide Series: Black silicon carbide (C), green silicon carbide (GC), cubic silicon carbide (SC), and cubic boron carbide (BC).
Superabrasives: Synthetic diamonds (RVD, MBD, SCD, SMD, DMD, M-SD) and cubic boron nitride (CBN, M-CBN).
Rubber bonded abrasives are produced by mixing abrasive grains with natural or synthetic rubber as the bonding agent, followed by shaping and heat vulcanization. These products exhibit the grinding characteristics of conventional abrasives and the unique performance features of rubber products, making them indispensable in grinding applications. Rubber abrasives account for approximately 5% of the total abrasive tools market.
The rubber bonded abrasives can be used for:
Hard Abrasives: These are used for making bearing grinding wheels, thread grinding wheels, and centerless grinding guide wheels.
Precision Grinding: Widely applied in the bearing industry, rubber bonded abrasives are also used to create thin rubber abrasive discs with thicknesses as small as 0.08mm. These are suitable for grooving and slotting precision instruments, tools, and components, as well as cutting and separating precious metals, yielding grooves with high surface quality.
Flexible Polishing Wheels: These are used for polishing and finishing precision components and tools.
Rubber bonded abrasives typically use brown fused alumina and white fused alumina as the abrasive grains. Some tools may incorporate microcrystalline alumina, green silicon carbide, or black silicon carbide. The particle size range for abrasive raw materials generally falls between F80–F120, with some applications using sizes such as F40–F60 and F150–F240, and a few cases involving finer sizes like F280, F400, or even F800.
We not only provide high-quality abrasive grains, but also provide you with professional production advice and consulting services.
The typical products of thin wheels are resin bonded cutoffs and depressed center grinding wheels.
For the general hardware market, regular brown fused alumina and white fused alumina are basic raw materials to produce them.
For stainless steel cutting, if needs sharper, get the fast cutting effect, coated white fused alumina or monocrystalline alumina is a good choice.
For the grinding of carbon steel, if needs a better product life in higher grinding pressure condition, coated brown fused alumina or zirconia alumina 25 is a better choice.
The typical products of heavy duty wheels are large diameter cutting wheels and roll grinding wheels. monocrystalline alumina, 1350 calcined alumina or zirconia alumina 25 is a good choice.
The made rubber abrasive wheels are highly suited for the precision grinding, de-burring of high carbon steels, high temperature alloys. The made PVA & PU wheels are highly suited for polishing , AM10 is a better choice.
