Surface grinding machines is a kind of grinder. The grinding wheel is mainly used to rotate and grind the workpiece to achieve the required flatness. According to the shape of the worktable, it can be divided into two types: rectangular worktable and round worktable. The main parameters of the rectangular worktable surface grinding machines are the width and length of the worktable. The main parameter of the shaped worktable is the diameter of the worktable. According to the different types of shafts, it can be divided into horizontal shaft and vertical shaft grinders.
A surface grinding machines is a type of grinder that grinds the flat or shaped surface 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 grinding machines. Here are a few common categories:
①Horizontal axis and rectangular table surface grinding machines: 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 dovetail guide rail of the sliding seat (see machine tool guide) (see machine tool), and the sliding seat can make vertical intermittent feed movement along the guide rail of the column. The grinding wheel is used to grind the workpiece with better grinding accuracy. high.
②Vertical spindle and round table surface grinding machines: The vertically arranged grinding wheel spindle grinds the workpiece with the end face of the grinding wheel, and the grinding wheel carriage 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 production efficiency 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 worktable to tilt and grind annular workpieces with different thicknesses.
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 by using 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 a linear or rotary feeding device. This kind of grinder is very efficient 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.
