Surface grinder is a type of grinder that grinds the surface or shape of a workpiece. The main types are horizontal axis rectangular table, horizontal axis round table, vertical axis rectangular table, vertical axis round table and various special surface grinders.
①Horizontal axis and rectangular table surface grinder: The workpiece is sucked or clamped on the worktable by the rectangular electromagnetic worktable, and reciprocating longitudinally. The grinding wheel carriage can make transverse intermittent feed movement along the slide’s dovetail guide rail (see machine tool guide) (see machine tool), and the carriage can make vertical intermittent feed movement along the column guide rail. The workpiece is ground around the grinding wheel, and the grinding accuracy is better. high.
②Vertical spindle and round table surface grinder: The vertically arranged grinding wheel spindle grinds the workpiece with the end face of the grinding wheel, and the grinding wheel holder can make intermittent vertical feed movement along the guide rail of the column. The workpiece can be continuously ground on the rotating round table, and the output power is high. In order to facilitate the loading and unloading of workpieces, the round table can also move longitudinally along the bed rails.
③Horizontal axis round table surface grinder: It is suitable for grinding round and thin workpieces, and can use the table to slant to grind annular workpieces of varying thickness.
④Vertical axis and rectangular table surface grinder: Since the diameter of the grinding wheel is larger than the width of the worktable, the grinding area is larger, which is suitable for high-efficiency grinding.
⑤Double-end face grinder: Grinding two parallel planes of the workpiece at the same time with the end faces of the grinding wheels of two grinding heads. There are two types of horizontal axis and vertical axis. The workpiece is guided through the grinding wheel by linear or rotary feeding equipment. This kind of grinding machine has high power and is suitable for mass production of parts such as bearing rings and piston rings. In addition, there are rail grinders dedicated to grinding machine tool rail surfaces, and special grinders for grinding turbine blade profiles.
