Surface grinding machines are very important in industry and are used to manufacture parts and industrial tools. It needs smooth movement and normal operation. It is also used in industries that need to define the shape accurately, such as the manufacturing of automobile parts. Cast iron, steel, brass, plastic and aluminum are all materials that can be polished by surface grinding machines. Now, let's introduce the surface grinder.

一、What is a surface grinder

The surface grinder consists of a grinding wheel covered with hard abrasive, a chuck and a workbench. When the wheel grinds and smoothes the non-metallic object, the non-metallic object can be kept in place by vacuum or mechanical chuck. The metal objects are fixed by electromagnetic suction cups.

Surface grinding machine refers to a kind of grinding machine that grinds the surface or formed surface of the workpiece. It is suitable for processing brittle materials such as hard steel, hard alloy and glass and granite; Such as precision mechanical parts, etc., are processed, materials are trimmed within one tenth (0.0002 inch), cutting tools are ground, and punches and dies are ground. Surface grinder usually consists of an electromagnetic chuck similar to a workbench, a grinding wheel fixed on the rotating spindle and several hand wheels (for manual operation).

Surface grinding machine is one of the common grinding machines in ordinary workshops. The surface grinder can be divided into rectangular and circular worktables according to the shape of the worktable. The main parameters of the rectangular worktable surface grinder are the width and length of the worktable, and the main parameters of the circular table surface grinder are the diameter of the worktable. Its main types are horizontal axis rectangular table, horizontal axis circular table, vertical axis rectangular table, vertical axis circular table and various special surface grinding machines.

二、What to pay attention to when using surface grinder

Surface grinder is a kind of tool that uses fixed and abrasive rotating wheels to shave or trim the metal surface. Surface grinding machines can be dangerous if used improperly. So before using the surface grinder, we need to know the following points:

1. Ensure that the grinder has an emergency start/stop button (emergency stop) that works normally within easy reach of the operator.

2. Please install the grinding wheel according to the manufacturer's instructions. Before each use, be sure to check whether the grinding wheel is damaged or worn to ensure that it is properly maintained and kept in good working condition.

3. Make sure that the wheel guard covers at least half of the wheel.

4. Ensure that all parts, switches and plugs are in good working condition.

6. Make sure that the material you are forming can be used in the grinder. Soft materials such as aluminum or brass may clog the wheel and prevent it from operating effectively.

7. Make sure that the material is securely held in place with a vise.

8. Before starting the grinder, please check whether the wheel has removed the workpiece.

9. Before putting the new grinding wheel into operation, please run the new grinding wheel for about one minute.

10. Wait for the wheel to reach a higher speed before using it, because there may be an invisible fault.

11. Before stopping the wheels, turn off the coolant to avoid imbalance.
