There are many types of grinders, so what is the main purpose of surface grinders? Surface grinders mainly use grinding wheels to rotate and grind the workpiece to achieve the required flatness. According to the shape of the worktable, it can be divided into rectangular worktables and circular worktables. The main parameters of the rectangular table surface grinder are the width and length of the table, and the main parameter of the round table surface grinder is the diameter of the table surface.

What should be paid attention to during the specific operation of the surface grinder?
1: Positioning rules for surface grinders
Where should the machine 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 wheels for surface grinders
The selected grinding wheel must be able to withstand the weekly rotation speed of 2000m/min or more, because if the rotation speed is too low, it will be easy to leave marks, but if the rotation speed is too high, the price of the grinding wheel will be much higher. In addition, special attention should be paid to strictly prohibit Use a broken wheel. If possible, it is best to do the flanges that must be balanced after the new grinding wheel is installed.

3: Surface grinder spindle
Before installing the grinding wheel, make sure that the spindle rotates clockwise.
4: Hydraulic device of 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, and the oil tank must be cleaned.
5: Lubrication device of surface grinder
The lubricating oil uses the guideway lubricating oil with a viscosity of 32. (Recommend Mevista No. 1 or No. 1405)
Confirm the oil volume of the oil 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: Left and right mechanism of surface grinder
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. (This article applies to manual models)
7: Surface grinder flushing and dust suction device
The cleaning and maintenance of the dust box filter should be 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.
