Diamond Cut Off Wheel

Diamond cutting wheel is mainly used for grooving and cutting.
  • High precision, it can be used for precision grooving and cutting, reducing process.
  • Narrow cutting crack, greatly improve the utilization ratio of raw materials.
  • High efficiency and sharp cutting
  • High rigidity, high strength and long service life

Types of diamond cut off wheel

According to the structure, it is divided into hub type and hubless type, Some blades are also called diamond dicing blades.

Hub diamond cut off wheel refers that the outer ring the grinding wheel is an abrasive layer, and central part is high strength and high rigid metal materials, also known as outer ring diamond cut off wheel. There are two kinds of metal bond and resin bond.

Metal bond cut off wheel has high bonding strength, wear resistance, good shape retention, and long service life.

Metal bonded diamond cut off wheel

Resin bond cut off wheel has elasticity, good surface quality, the good edge for abrasive grains, sharp cutting and high efficiency.

The main models of diamond cut off wheels are 1A1/3, 1A1R/4, 1A1/5 and 1A1R/6.

1A1/3 and 1A1R/4 refer to the hub type cut off wheels without water slot, and 1A1/5 and 1A1R/6 refer to the outer with water slot.

1A1 type diamond cut off wheel

Main features: The thickness of abrasive working layer is the same as that of the matrix.

High precision, mostly used for high precision grooving and cutting

1A1R type diamond cut off wheel

Main features: The thickness of the abrasive working layer is thicker than that of the matrix. It is easy to chip removal and cooling, and mostly used for deep cutting and grooving of components.


Order Guideline:

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

Types: 1A8, 1A1, 1A1R, 3A1, 14A1, 1B1, 1E1, etc.

Specifications: abrasive, grit, bond type, outer diameter, thickness, inner diameter, working layer width, matrix thickness, etc.

Usages: workpiece name, cutting size, cutting material, grooving or cutting off, etc.

Application conditions: machine, grinding wheel speed, feed speed, cutting depth, dry or wet cutting, etc.
