Surface grinding machine is a machine tool for grinding the surface of the workpiece, mainly used for surface grinding of metal, non-metal and carbide materials. The working principle is to grind the surface of the workpiece through the high-speed rotation of the wheel, so as to achieve the purpose of improving the surface accuracy and finish of the workpiece. Widely used in machinery manufacturing, aerospace, mold manufacturing, automobile manufacturing and other fields, is an important equipment in modern manufacturing industry.

The main structure of surface grinding machine includes bed, workbench, grinding wheel frame, grinding wheel, head frame, tail frame, hydraulic system, electrical system and so on. The bed is the foundation that supports the weight of the entire machine tool and ensures the stability and rigidity of the machine tool. The workbench is a platform used to fix the workpiece, which can be reciprocated in the horizontal direction to achieve the grinding of the workpiece. The grinding wheel holder is a component used to support the grinding wheel and can be fine-tuned vertically to accommodate workpieces of different thicknesses. The grinding wheel is the main grinding tool, which is driven by the sand wheel shaft to rotate at high speed and grind the workpiece surface. The head frame and the tail frame are located at both ends of the table to fix the workpiece and ensure the stability of the workpiece during grinding. The hydraulic system and electrical system respectively provide power and control for the grinding machine to ensure the normal operation of the machine.

The operation process mainly includes the following steps:

1. Preparation: First of all, check whether the components are in good condition to ensure that the machine tool has no abnormal conditions. Then according to the size and shape of the workpiece, the appropriate grinding wheel is selected and installed on the grinding wheel frame. At the same time, fix the workpiece on the work table, adjust the position of the head and tail frame, so that the workpiece and the grinding wheel to maintain a proper grinding distance.

2. Grinding process: Start the grinder to make the grinding wheel rotate at high speed. By operating the table, the workpiece is reciprocated in the horizontal direction and in contact with the grinding wheel for grinding. In the grinding process, the distance between the grinding wheel and the workpiece can be changed by adjusting the height of the grinding wheel frame to ensure the grinding effect. At the same time, it is necessary to pay close attention to the phenomena such as sparks and grinding sounds during the grinding process, so as to discover and deal with abnormal situations in time.

3. Grinding end: When the workpiece surface reaches the predetermined accuracy and finish requirements, stop the grinding machine and remove the workpiece. Then turn off the power supply of the machine tool, clean the grinding chips and coolant on the machine tool, and keep the machine tool clean and tidy.

Surface grinding machine in the process of use, need to pay attention to the following points:

1. Choose the right grinding wheel: according to the workpiece material and grinding requirements, choose the right type of grinding wheel and particle size to ensure the grinding effect.

2. Keep the machine clean: regularly clean the grinding chips and coolant on the machine tool to avoid affecting the normal operation of the machine tool and the grinding effect.

3. Pay attention to safety protection: When operating the grinder, comply with safety procedures and wear protective equipment to avoid accidental injury.

4. Regular maintenance: regular inspection and maintenance to ensure the normal operation and service life of the machine tool.
