Electroplated Diamond/CBN Grinding Wheels

Main Feature: The electroplated grinding wheel is with high concentration, sharp grinding, high working efficiency, and no need to finish. The product can be made into different shapes. It is especially suitable for complicated, thin, small, geometrical shapes or processing products with precise dimensions required. It helps promote working efficiency and solve grinding problems for some special products and is extremely suitable for dry grinding.

Electroplated diamond wheel applications: ceramics, glass, hard alloy, ferrite, and high-hardness nonmetallic materials, etc.

Electroplated CBN wheel applications: metal materials like chilled cast iron, cast alloy steel, titanium alloy, etc.

Table of Contents of The Page

Introducing all aspects of Diamond&CBN grinding wheels is not easy, so we have prepared a lot of information on this page for you. To ensure that you can quickly find the information you want to access, we have designed this content directory that will jump to the appropriate location when you click on it.

Diamond & CBN Grinding Wheel Mark Sequence

According to GB/T6409-199®, the feature and writing sequence for diamond or CBN grinding tools are as follows:

Shape Code, Dimension, Grinding Material Model, Granularity, Binding Agent, Concentration.

The mark of Dimension sequence is
External Diameter x Overall Thickness x Hole Diameter x Width of Grinding Material Layer x Thickness of Grinding Material Layer
For some grinding wheels with bevel edge or circular arc, the angle of edge or the radius of arc should be marked.

Some product examples

Our products are manufactured with high-quality diamond powder.It is very hard-wearing and durable. Quality is our commitment to our customers, ensuring every production process has been rigorously tested for longer service life.

3A1 Diamond Cut Off Wheels

It is widely used for high speed surface/ cylindrical /conical / flat surface /conical apertures grinding(HSG) of tungsten carbide on grinding machine.

Binding Agent Choose

Diamond/CBN grinding wheel is divided into different kinds according to agent sorts, like resin bond, metal bond, vitrified bond, and Electroplated bond. A suitable binding agent must be chosen according to processing objectives.

Binding AgentCode
Resin bondB
Metal bondM
Vitrified bondV
Electroplated bondP

Granularity (Grit Size)Choose

The roughness degree of artificial diamond is shown as granularity code. The surface roughness degree is affected by granularity directly. The principle of choosing granularity is to choose thick ones based on the premise of meeting processing unit requirements. Therefore, the grinding efficiency is reinforced, and the loss of the grinding wheel is reduced.
The granularity of the diamond is between 30# and W1 as follows:

Grinding ProcedureGranularity Recommended
Rough Grinding30#-120#
Half-precise Grinding150#-240#
Precise Grinding280#-W40

Attention for operation

1. Please check the grinding wheel carefully. For any notch or damage, please stop using it immediately.
2. For grinding wheels marked with a rotating direction, please make sure the rotating turning direction of the machine is the same. The grinding wheel’s efficiency will be affected by wrong direction operation.
3. For any abnormal conditions during grinding, please stop the machine and check the problems immediately.
4. When the grinding wheel is not sharp, it is required to get it edged. Continuous operation may cause overheating and overload and then damage the grinding wheel.
5. It is forbidden to use a hand or any part of the body to grind or touch the grinding wheel.
6. Special-designed grinding wheel is not suggested for common grinding in order to avoid any abnormality or damage.
