ELECTROPLATED DIAMOND PRODUCTS

Electroplated Diamond Products

Varun Udyog Electroplated Diamond / CBN tools are processed using carefully selected diamond particles having rough edges. These tools have a single layer of diamond. The electroplated layer allows exotic forms to be accurately coated which is not possible in the sintering process. It gives very cool cutting on wet or dry applications.

Basics Of Electroplated Bond

Normally for electroplated bonds a single layer of abrasive grain is applied. The abrasive grains are usually sprinkled on the wheel body and help by a metallic matrix.

Since Nickel is used as the branding material, it lends its basic properties to the wheel: Hardness, Toughness, Adhesive, Resistance to Wear

Advantages

The numerous grits projecting from the branding matrix lend a lot of advantages for the electroplated bonded wheels.
1. Ability to grip firmly
2. Extremely high grinding performance
3. Can grind even strong ductile material
4. Have a tool life of 1 to 100 ground meters depending on grit size and grinding.

Often the finished surfaces are somewhat rougher than those ground with the same grit size in bonds such as resin bond, metal bond or vitrified bond. An improvement of the surface comes gradually with the microcrystalline wear of the grit points and the increase of cutting edges so that the electroplated grinding tools is always characterized by the variation of the achievable surface quality over the service life.

Characteristic

Single grit layer in an extremely stable bond
High geometric and proportion precision
Extremely high grinding performance
High abrasive due o high grit protrusion
Very good dressing behaviour
Body can be re-plated several times
Long tool life
High geometric stability
No dressing procedure necessary
Static grit arrangement on the steel body.

Diamond Slitting Wheels

Varun Udyog Diamond Saws are highly efficient in cutting hard materials such as carbides, ferro magnets, glass fibre, bakelite, glass ,hard plastics, brake lining etc.

Standard sizes of 4, 6, 8, 10, 12, 18, 20 inches are readily available in thickness from 0.4 mm to 3.0 mm or as specified.

Grit Size : 80 / 100 (Rough), 120 / 140 (Medium), 200 / 240 (Fine), or as specified.

Diamond & CBN Internal Grinding Wheels

Diamond Internal Grinding Wheels are suited for non ferrous materials such as Tungsten Carbide, Ceramics, Sapphire, Glass, Stones, Fibre Reinforced Plastics etc. CBN Internal Grinding Wheels are usually used for hard ferrous materials over 45 HRC such as High Carbon and High Carbon High Chrome Steels etc.

Available in sizes varying from 1.0 mm to 20 mm or as specified.

Grit Size: 80 / 100 (Rough), 120 / 140 (Medium), 200 / 240 (Fine) or as specified.

Diamond Core Drills

Sizes from 3.5mm – 60mm
For Drilling Stone, Tile, Glass Bottles, Shell, Ceramic, Concrete Porcelain and more. These diamond core drill bits are still our most popular tools for drilling through hard materials. Sometimes referred to as diamond hole saws or diamond coring drills, they will produce a hole in whatever you put in front of them.

Diamond grit is precisely electroplated onto a steel shank
Drilling Depth: from 25mm to 35mm
Sizes stated are +/- 0.2mm
Wall thickness: 1mm – 1.5mm

THIN WALL DIAMOND CORE DRILLS

These electroplated diamond core drill bits have a thin wall in comparison with our standard diamond core drills. The thin wall allows for a more precise cut with a better surface finish and less chipping. They should be used on delicate, hard materials such as optical glass, watch glass, sheet glass, thin glass, thin slices of stone, or any stone that is 6.5 or below on the Moh’s scale of hardness.
