The influence of abrasive structure on grinding performance of grinding wheel:

Abrasive organization is the density of abrasive distribution which plays a major role in grinding. It can also be said that it is the volume distribution of abrasive in the abrasive, which is expressed by the volume percentage of abrasive in the abrasive. The volume percentage of abrasive particles in abrasive tools is called abrasive rate.

Abrasive particles are the main factors in abrasive tools to cut the surface of workpiece. The abrasive rate determines the number of abrasive grains per unit area of the grinding tool in the grinding area, because it greatly affects the grinding performance and quality of the grinding tool.

We can make customized formula after professional analysis of the workpiece material, processing parameters and conditions, and processing requirements of customers in the early stage of grinding wheel design. Especially, the effective number of grains per unit area of grinding wheel affects a series of grinding performance indexes such as specific energy, surface quality, grinding heat, grinding force and grinding efficiency. Therefore, in the manufacturing process of abrasive tools, the company controls the density of abrasive particle distribution.

Brief Introduction of Different Bonded Type of Diamond And CBN Tools:

• Resin bonded diamond series: resin bonded diamond and cubic boron nitride grinding wheels are abrasive tools and tools of various shapes made of diamond or cubic boron nitride and resin bonded.

         Features: high grinding efficiency, less heat, good self sharpening, not easy to block. The surface roughness of                       machined workpiece is low. Such as glass, ceramic.

         Applications: widely used in cemented carbide fine grinding, semi fine grinding, grinding, polishing, porcelain,

         stone and other non-metallic materials fine grinding.

• Diamond bronze bond series: it is an abrasive tool and tool made by pressing and high temperature sintering with diamond or cubic boron nitride as abrasive and metal powder as bond.

         Features: strong binding force, good wear resistance, long service life, good shape retention, can withstand heavy load

         grinding.

         Application: mainly used for grinding and cutting of glass, gem, stone, semiconductor material, brake pad, and                     electrolytic grinding of cemented carbide. 

• Ceramic bonded diamond grinding wheel series:

         Features: 1. High edge strength, i.e. high grinding efficiency and good self sharpening of grinding wheel;

         2. Good shape retention; 3. Easy correction; 4. High durability and long service life of grinding wheel; 5. High quality

         of knife edge.

        Purpose: it is mainly used for fast, high efficiency and low loss grinding of PCD, PCBN, cemented carbide tools and

        other cutting tools.

• Diamond / resin cutting chip series:

         Diamond cutting chip: mainly used for optical glass, gem, crystal, ceramics, marble, cemented carbide, tungsten

         steel, ferrite, semiconductor, etc.

         Diamond resin cutting chip: mainly used for glass, glass tube / plate, gem, crystal, ceramics, cemented carbide,

         tungsten steel, ferrite, monocrystalline silicon / polycrystalline silicon, silicon rod, semiconductor, etc

Precautions for use:

• Please check carefully before installing the cutting wheel. If there is any gap or other damage, please stop using it.

• When the cutting wheel is marked with the rotation direction, it should be consistent with the rotation direction of the machine tool. On the contrary, the cutting is not sharp, and it is difficult to give full play to the performance of the cutting wheel.

• Please do not use the cutting wheel that does not meet the requirements.

• If any abnormality is found in the cutting process, stop the machine immediately and check the cause.

• When the cutting is not sharp, the grinding wheel should be trimmed. If it is used continuously, the grinding wheel may be damaged due to overheating and overload.

• When the grinding wheel rotates, it is strictly forbidden to cut by hand, let alone touch the sand by hand and body

• The cutting wheel is forbidden to be used in operations other than grooving or cutting, so as to avoid abnormal operation due to uneven stress.

Ordering instructions:

When you order for the first time, please provide the following parameters, so that we can help you choose the most suitable cutting wheel.

Specification and size: abrasive, particle size, binder, outer diameter, thickness, inner diameter, abrasive working layer width, substrate thickness, etc. purpose: workpiece name, cutting size, cutting material;

Service conditions of grooving and cutting: machine tool, grinding wheel speed, feed speed and cutting depth;

Dry and wet cutting requirements: cutting accuracy, chipping requirements, processing surface integrity, etc

Special requirements: whether the tool is assembled and used, whether the resin cutting wheel needs to conduct electricity, whether the outer circle of the cutting wheel has a water tank, the size and quantity of the water tank, whether there is a chip removal groove on the outer side of the cutting wheel base, etc.
