A type of grinding machine. The grinding wheel is mainly used to rotate the workpiece to achieve the required flatness. According to the shape of the table, it can be divided into two types: a rectangular table and a circular table. The main parameters of the rectangular table surface grinder are the width and length of the table, and the round table. The main parameter of a surface grinder is the work surface diameter. According to the different types of shafts, it can be divided into horizontal shaft and vertical shaft grinding machine. Such as M7432 vertical axis round table surface grinder, 4080 horizontal axis rectangular table surface grinder.

A type of grinding machine that grinds a workpiece plane or a profiled surface. The main types are horizontal axis moment table, horizontal axis round table, vertical axis rectangular table, vertical axis round table and various special surface grinders.

1 Horizontal axis table surface grinder: The workpiece is sucked or clamped on the table by a rectangular electromagnetic table, and is longitudinally reciprocated. The grinding wheel frame can be used for lateral intermittent feeding movement along the dovetail guide rail of the sliding seat (see machine guide rail) (see machine tool). The sliding seat can be used for vertical intermittent feeding movement along the guide rail of the vertical column. The workpiece is ground by the grinding wheel, and the grinding precision is better. high.

2 Vertical shaft round table surface grinder: The vertically placed grinding wheel main shaft grinds the workpiece with the grinding wheel end face. The grinding wheel frame can make intermittent vertical feeding motion along the guide rail of the vertical column. The workpiece is mounted on a rotating circular table for continuous grinding and high production efficiency. In order to facilitate the loading and unloading of the workpiece, the circular table can also be moved longitudinally along the bed rail.

3 horizontal axis round table surface grinder: suitable for grinding round sheet workpieces, and can be used to tilt and grind round workpieces with different thickness.

4 vertical axis table grinding machine: Because the diameter of the grinding wheel is larger than the width of the table, the grinding area is large, which is suitable for efficient grinding.

5 double-face grinding machine: the two parallel planes of the workpiece are simultaneously ground by the grinding wheel end faces of the two grinding heads, and there are two types of horizontal shaft and vertical shaft. The workpiece is guided through the grinding wheel by a linear or rotary feeding device. This type of grinding machine is highly efficient and is suitable for mass production of parts such as bearing rings and piston rings. In addition, there are guide grinding machines for grinding the guide surface of machine tools, and special grinding machines for grinding turbine blade profiles.
