Tool grinding wheel

Structure of grinding wheel

(1) Grinding wheel: by abrasive and bond together made of round cake or ring shape, through the rotation of the workpiece grinding tool.

(2) Traditional grinding wheel: round cake or ring-shaped grinding wheel made of alumina abrasive and bond, we call it traditional grinding wheel.

(3) The three elements that constitute the grinding wheel: from Figure 2-1, it can be seen that it is composed of abrasive, bond and air hole.

Tool dressing – grinding wheel dressing

The diamond dresser is commonly used to fix the diamond on the steel handle by welding, embedding and sintering. There are many kinds of diamond dressers, including single stone type, multi group type, multi stone type and cluster type.

Positive angle device to ensure the perpendicularity of the workpiece

Backing plate – clamping and tool setting datum

The backup plate is fixed on the side of the platform, which is used as the reference for clamping and positioning the workpiece in the front and rear (y) direction; The platform is used as the reference for clamping and positioning the workpiece in the up and down (z) direction.

Angle forming – machining bevel (forming wheel)

The angle shaper is used to trim the inclined surface of the grinding wheel by using the sine theorem and the pad gauge to make the sliding surface of the angle shaper incline to an angle, so that the cutter on the angle shaper can slide back and forth to cut the grinding wheel with this inclined surface as the sliding track, so as to achieve the purpose of dressing the inclined surface of the grinding wheel. In bevel machining, it is the most important fixture for dressing shaped grinding wheel, which is convenient and fast to use.

Sinusoidal stage is also one of the most important fixture in the machining of inclined plane, which is generally used for machining of larger inclined plane. Its principle is the same as that of the angle shaper. It also uses the sinusoidal principle to realize the forming of the upper inclined plane of the workpiece through the pad gauge.

Punch shaper

Round bar is an important part of die. Cylindrical grinder is an excellent equipment for round bar machining, but surface grinder with punch shaper is suitable for small round bar workers with high machining accuracy and complex forming.
