Synthetic Diamond

RVD1 RVD2 MBD4

MBD6 MBD8 SMD
Synthetic Diamond is the good material for manufacturing core bits, saw blade, segments, grinding wheel and ultra-hard material products etc.

1.Synthetic diamond brand and applications

Brand	Crystal Features	Application
RVD1	The crystals of RVD1 are irregularly flaky and needle-like with rough surfaces.	Recommended in manufacture of resin bond products for carbides and jewel.
RVD2	With ratio of major axis and minor axis not more than 1.5, most crystals are irregular, with rough surfaces.	Recommended in manufacture of metal bond products for grinding carbides and other nonmetallic materials.
MBD4	MBD4 contains more perfect crystals with smooth surfaces. And high compressive strength.	Suitable for manufacture of metal bond products for grinding, sawing and drilling cement products, glass, refractories and other nonmetallic materials.
MBD6	MBD6 contains perfect crystals with smooth surfaces and high compressive strength.	Particularly suit for mining bits used in hardest strata for dressing tools and saws.
MBD8	MBD8 diamond contains perfect crystals with smooth surfaces. And very high compressive strengths.	MBD8 is ideal for bits, dressing tools and saws.
SMD	SMD are prefect crystals with high strength and high toughness.	It is used in sawing, cutting ,drilling and dressing tools.

3.Synthetic diamond coated with Ni and Cu

SD-Ni is synthetic diamond coated with nickel to improve the bonding ability between resin or metal and diamond.
Recommended for resin bond wheels for wet grinding of carbide and some ceramics, good durability with high grinding efficiency.
SD-Cu is RVD1 coated with copper to improve the bonding ability between resin and diamond. Recommended for dry grinding of carbide, good durability with high grinding efficiency.
