Among those famous China white corundum grinding wheel manufacturers, Yinglong Superhard Materials Manufactory is a professional such supplier, welcome to buy white corundum grinding wheel production with our factory.

White Corundum Grinding Whee


White corundum (WA) grinding wheel for grinding, high hardness of the steel, such as high speed steel, high carbon steel, hardened steel, alloy steel, I plant the production of white corundum grinding wheel parallel cup, Bai Gang cup emery wheel, white corundum wheel cylinder, jade Bai Gang wheel and other varieties, according to customer drawings custom shaped white corundum grinding wheel.

1. Abrasive Material:

Category

Features

Usage

Brown Corundum

(A)

High hardness and toughness

It can be used for grinding medium

and high tensile strength metal such

as ordinary carbon steel, alloy steels,

 malleable cast iron, hard bronze etc.

White

Corundum

(WA)

Its hardness is higher than that of the

A. Grains are easily broken. The edges

of the grains are sharp with excellent

cutting performance small quantity is produced.

It can be used for grinding harder

material and metals sensitive to heat

such as chilled steel, high carbon steel

ordinary high speed steel, alloy steel .

it is specially suitable for the grinding

and forming grinding instruments,

cutting tools, gears threads, thin wall parts, etc

Pink Corundum

(PA)

The hardness is close to WA,

 but the hardness is higher.

The grains are sharp. It is much durable,

Used for the grinding of the chilled steel,

cutting tools and work-pieces of alloy

steel as well as the precision grinding

 of the measuring tools and parts of the instruments.

Mixture of A and WA

(A/WA)

It possesses the advantage

of both A and WA

It is suitable for the grinding of nodular,

 cast iron crank shaft, cam shafts

and other work-pieces.

Green Silicon

Carbide (GC)

With high hardness and brittle.

Its grain edges are sharp,

and it is of excellent capacity of the heat –transmission.

It is suitable for the grinding of the

 cutting tools and work-pieces of hard

 alloy, and non-ferrous metal and

non-metal materials

Black Silicon

Carbide (C)

With high hardness and brittle.

Its grain edges are sharp and it is

of certain capacity of the heat –transmission.

It is suitable for the grinding

 of non-ferrous and non–metal materials.


2. Choice the Grit. Sizes

Usage

4,5,6,8,10,12,14,16,20,22,24,30

Rough Grinding and Cutting

36,40,46,54

                     Common Semi-precision Grinding

60,70,80,90,100

Common Fine Grinding

120,150,180,220,240,W63,W50,W40,W28.W20

Polishing and Threading

              W14,W10,W7,W5,W3.5,W2.5W1.5,W1.0,W0.5

Mirror –surface grinding and Finer Polishing


3. To Choose the Bonds:
①Vitrified Bond. It is suitable for the cylindrical grinding and ex-circular grinding , center-less grinding .surface grinding and thread grinding ,forming –grinding etc.
②Resign Bond. It can used to grind the steel precision grinding of the stones, cutting and polishing, but it should be kept away from alkaline solution


4. Hardness.
The Hardness of the abrasive tools indicates the difficulty of abrasive tools falling off the surface of the abrasive tools in cutting. Generally, the grinding wheels in soft hardness are used for cutting harder work-pieces, whereas the wheels in a bit higher hardness are used for cutting soft work-pieces


5. Structure No.
Structure No. is the percentage of the grain volume in the volume of the abrasive tools. The bigger the grain is,the denser the structure is other, the structure is porous .The abrasive tools in the porous structure are characterized by more holes among grains and easily removing metal fillings, and excellent capacity of heat –radiating and burning no work-pieces, the one in dense structure feature well, which can keep the shape well and high clearness of the work-Pieces, also high grinding efficiency.
