High precision and superthin superabrasive cutting wheels
The high precision superabrasive cutting wheels are mainly used for precise
cutting and slotting kinds of electronic component and precise part in the electronic
information and the mechanical fields.
Main features
1.High precision, for grooving and cutting with less procedure
2.Narrow cutting kerfs, for saving valuable material
3.Sharp-edged, high efficiency
4.Good rigidity, high strength and long life span
Cutting wheels without steel plate
The cutting wheels without steel plate are manufactured with identical material.
Thin thickness and high precision, they are mainly used for grooving and cutting with high
accuracy and slight cutting depth.
There are two kinds of bond: metal bond (M) and resin bond (B).

Metal bond cutting wheels without steel plate
1.The grits are strongly held by the metal bond,
2.The wheels have good wear resistance,good shape maintenance and long life span.
Resin bond cutting wheels without steel plate
The resin bond cutting wheels can self-sharpen and cut sharply. The quality of surface can
be improved due to the elastic resin bond.
Spec. and dimension of the high precision cutting wheels without steel plate
The models of cutting wheels without steel plate divide into 1A8/1 type without water slot
and 1A8/2 type with water slot.

Model specification and the precision for reference（mm）
High precision cutting wheels with steel core
This kind of cutting wheel is compound of steel plate and work layer.The steel plate has
high strength and high rigidity.They are generally used for deep cutting and grooving.
The cutting wheel bond divides into three kinds: the metal bond (M) ,resin bond (B) and mix
-ture of metal and resin(M/B).
Metal bond cutting wheels:
The grits are strongly held on; the wheels have good wear resistance, long life span and
good shape maintenance.
Resin bond cutting wheels:These wheels can self-sharpen and cut sharply.
The work quality can be improved due to the elastic resin bond.
The spec and dimension of the high precision cutting wheels with steel plate
The models of cutting wheels with steel plate divide into 1A1/3、
1A1R/4 type without water slot and 1A1/5、
1A1R/6 type with water slot.

Cutting wheels of 1A1 type：
The thickness of work layer is as same as steel plate.
They are mainly used for precise grooving and cutting.
Cutting wheels of 1A1R type
The thickness of work layer is higher than the steel plate.
They have advantages for removing chips and cooling.
They are mainly used for deep cutting and grooving of component.
Model specification for reference and the precision（mm）
