- In-feed & Though-feed method
Centerless grinding utilizes natural friction and natural wear to perform processing, which fully reduces energy consumption and has the characteristics of high efficiency and energy saving.
The centerless grinding wheel is installed on the centerless grinding machine. It interacts with the guide wheel and surpport plate to form a kind of grinding method. The workpiece is supported by the support plate, and the workpiece is driven to rotate by a uniform circular motion from the guide wheel to the direction of the support plate, it is ground by the centerless grinding wheel. It is a kind of external cylindrical grinding wheel, which is mainly used for bars.
The centerless grinding method is composed of three mechanisms: grinding wheel, adjustment wheel, and workpiece support (support plate). The grinding wheel actually performs the grinding work, and the adjustment wheel controls the rotation of the workpiece, and the workpiece support is used to support the workpiece.

Features of Centerless Grinding Wheel:
High precision: As centerless grinding does not require a center hole, there is no impact of center hole deviation on workpiece accuracy, resulting in higher precision of the workpiece that is ground.
Good surface quality: During centerless grinding, there are fewer grinding marks on the surface of the workpiece, which can achieve better surface quality.
High production efficiency: Centerless grinding can grind multiple workpieces at the same time, greatly improving production efficiency.
Grinding Methods of Centerless Grinding Wheel:
Through-Feed Method ( Longitudinal Grinding)
The workpiece is fed along the axis of the grinding wheel for grinding, and adjust the inclination angle of guide wheel axis to achieve the axial feed of the workpiece.
It is suitable for needle rollers, cylindrical rollers without centeral holes and hollow pipe fittings such as chrome plated steel bars, bicycle front fork vertical pipes, piston rods, and need roller pins.
In-Feed Method
It is suitable for the workpiece with relatively complex shapes.
There is axial positioning fulcrums on the support plate, and the workpiece is supported at a certain position on the support plate, and in-feed grinding with grinding wheel or guide wheel. It is suitable for the conical, spherical, and cylindrical workpieces with convexity such as valve, movable shaft, transmission component, and billiard.

Selection of Centerless Grinding Wheel
Centerless grinding wheel is mainly used to grind workpieces. Its design can be adjusted for different workpiece materials and grinding requirements to achieve efficient grinding results.
Like other types of grinding wheels, the selection of centerless grinding wheel is still based on the features of the workpiece materials to be processed.
Therefore, centerless wheel can be corundum and silicon carbide grinding wheel, and also can be diamond or CBN grinding wheel. Both diamond centerless grinding wheel and CBN centerless grinding wheel have three types of bonding agent：resin bonded, metal bonded, and vitrified bonded.
Our company can provide customized services for CBN centerless grinding wheels and diamond centerless grinding wheels.
