The surface grinder mainly uses the 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 round worktable. The main parameters of the rectangular worktable surface grinder are the worktable width and Length, the main parameter of the round table surface grinder is the table diameter. In the specific operation process, the surface grinder needs to pay special attention to 7 major structures.

1. Positioning rules of surface grinder

Where should the machine tool be placed and how to install it? It is understood that more than 300mm should be reserved outside the maximum movement space, each foot screw should be tight, and the front, 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 wheel for surface grinder

The selected grinding wheel must be able to withstand a weekly speed of more than 2000m/min, because if the speed is too low, it will be easy to leave traces, but if the speed is too high, the price of the grinding wheel will be much higher. In addition, special attention should be paid to the strict prohibition. Use damaged grinding wheels. If you have conditions, you can do it after the new grinding wheel is installed. The flange must be balanced.

3. Grinding machine spindle, before installation, make sure that the spindle rotates clockwise.

4. Hydraulic device for surface grinder

The surface grinder uses hydraulic oil with a viscosity of No. 46. The hydraulic oil needs to be replaced after the new machine is used for three months, and then once a year in the future, and the oil tank must be cleaned at the same time.

5. Surface grinder lubrication device

The lubricating oil uses the guideway lubricating oil with a viscosity of 32. (Recommend Meiweida No. 1 or No. 1405), confirm the oil volume of the fuel tank (pool) every day to ensure that it is above the offline. 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 fuel tank every three months. Grease is added regularly as required.

6. Surface grinder left and right mechanism

It is forbidden to adjust the left and right stroke when the workbench is moving. When the workbench cable becomes loose, it should be adjusted immediately.

7. Surface grinder flushing and dust suction device.

The cleaning and maintenance of the filter of the vacuum box is cleaned every two weeks. The other is the inspection of the coolant. Generally, when the coolant is contaminated, it must be inspected and removed in time.
