Precision Unveiled with Surface Grinding Machines

A grinder, also known as a grinding machine or a grinding machine, is a common tool in the field of mechanical processing. Its function is to use a grinding tool to grind the surface of a workpiece. This type of machine tool has a wide range of applications, from the manufacture of precision parts to the grinding of tools, which are inseparable from the high-precision processing of the grinder.
Basic principles and composition of grindering machines
The grindering machine uses a high-speed rotating grinding wheel as a grinding tool. Through the shear deformation generated during the grinding process, small thin slices on the surface of the workpiece are removed to achieve the purpose of precision processing. Its basic structure includes a fixture for fixing the workpiece, a grinding wheel rotating at the required speed, and a grinding head that can control the position of the grinding wheel. In order to prevent overheating and improve the processing quality, the grinder is usually equipped with coolant.

Surface grindering machines
The surface grinder mainly uses a grinding wheel 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 circular 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 surface. In the specific operation process, there are 7 major structures that need special attention for the surface grinder.

1 Positioning rules for surface grinders: Where should the machine be placed and how should it be installed? It is understood that more than 300mm should be reserved outside the maximum movement space, each foot screw should be tight, and the front and back and left and right levels of the table should be within 0.04/1000mm. (The requirements for installing the inverter need to be higher)

2 Selection of grinding wheels for surface grindering machines: The selected grinding wheel must be able to withstand a peripheral speed of more than 2000m/min, because if the speed is too low, it will easily leave marks, but if the speed is too high, the price of the grinding wheel will be much higher. In addition, it is necessary to pay special attention to the fact that it is strictly forbidden to use damaged grinding wheels. If conditions permit, the flange must be balanced after the new grinding wheel is installed.

3 Spindle of surface grindering machines: Make sure that the spindle rotates clockwise before installation.

4 Hydraulic device of surface grindering machines: The surface grinder uses hydraulic oil with a viscosity of No. 46.  The hydraulic oil of the new machine needs to be replaced after three months of use, and once a year thereafter, and the oil tank must be cleaned at the same time.

5 Surface grindering machines lubrication device: Use guide rail lubricant with a viscosity of 32. (Recommended Meiweida No. 1 or No. 1405), confirm the oil level in the oil tank (pool) every day to ensure that it is above the lower line. Check whether the guide rail oil circuit is unobstructed every week to prevent the guide rail from losing oil. It is recommended to clean the oil tank once every three months. Grease should be added regularly as required.

6 Left and right mechanisms of surface grindering machines: It is forbidden to adjust the left and right strokes when the workbench is moving. When the workbench cable is loose, it should be adjusted immediately.

7 Surface grinder flushing and dust collection device: Cleaning and maintenance of the dust collection box filter, clean it once every two weeks. Another thing is the inspection of the coolant. Generally, when the coolant is contaminated, it should be checked and removed in time.

With the increasing demand for high-precision mechanical parts and the development of precision casting and precision forging processes, the performance, variety and output of grinders are constantly improving and increasing. In today’s era, plane polishing and grinding technology has become a grinding technology with development potential. Therefore, the research on ultra-precision grinding, polishing and other technologies will be more eye-catching in the future.
