What is Double-Side Fine Grinding?

Double grinding is considered one of the "classic" grinding processes, when it is necessary to grind both sides of a workpiece, it can be done so that both sides are flat and parallel to each other. During this process, the workpiece is not fixed and is not fixed into the "nest" of the workpiece carrier. Then, both sides of the workpiece are machined simultaneously between the two grinding wheels. The upper wheel is adjusted with a "tilt" guide setting, which allows the upper wheel to maintain the desired angle with the lower wheel. Therefore, the gap between the grinding wheels is larger on the cross-cut side than on the discharge side, which can meet the required grinding volume. With regular dressing, the grinding wheel can maintain its shape and sharpness.

 

 

Application of Flat Diamond Lapping Plate: grinding the surface, suitable for steel, cast iron, copper, carbide inserts, PCD/PCBN inserts, hard alloy, ceramics, monocrystalline silicon and other processing. Moresuperhard specializes in top and bottom finishing of carbide inserts, ceramic, PCD and CBN inserts for diverse OEMs.

Diamond/CBN double disc can be widely used in hydraulic pneumatic components, hydraulic motor parts, automobile fuel pump parts, refrigeration compressor parts, oil pump oil.

Vitrified Diamond cBN Double Disc Wheels can be divided into

- vitrified diamond grinding disc (the color of diamond pellets are white and yellow)

- vitrified CBN grinding disc ( the color of CBN pellets are black or brown)

Moresuperhard can also provide matching dressing grinding wheel of DDG wheel

According to the different particle size, accuracy of the diamond and CBN double disc grinding wheels to choose the dressing wheel, making dressing easier and more time saving. Mostly we use are silicon carbide(GC) dressing wheel while diameter is 205mm, grit 180#.

White corundum (WA) and green silicon carbide (GC) dressing wheels are introduced according to the characteristics and grinding performance of vitrified double disc grinding wheels.

    PCD material grinding sharpening technology

    Polycrystalline diamond (PCD) is a polycrystal formed by mixing micron-sized diamond powder with a small amount of metal powder (such as CO) and sintering at high temperature (1400°C) and high pressure (6000MPa). The disordered arrangement of diamond grains gives PCD uniform, extremely high hardness and wear resistance.
