Operating instructions for surface grinders

The surface grinder is a kind of grinder, which mainly uses the grinding wheel to rotate and grind the workpiece so that it can reach the required flatness.

1. Positioning of surface grinder

The machine tool should reserve more than 300mm outside the 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)

Check every three months, adjust the level of the work surface, and tighten each foot screw.

2. Grinding wheel for surface grinder

The selected grinding wheel must be able to withstand a rotation speed of more than 2000m/min.

Do not use damaged grinding wheels.

The flange of the new grinding wheel needs to be balanced.

Before the formal grinding, the grinding wheel should be idling for 5 minutes. The tool stroke is 0.03mm for grinders below 800mm, and 0.05mm for grinders above 800mm

3. Surface grinder spindle

Before installing the grinding wheel, make sure that the spindle rotates clockwise.

When turning on the machine, the spindle must be turned on first, and then the flushing must be started.

4. Hydraulic device of surface grinder

The surface grinder uses hydraulic oil with a viscosity of No. 46.

The new machine needs to replace the hydraulic oil after three months of use. In the future, it will be replaced once a year. At the same time, the oil tank must be cleaned.

Check the hydraulic oil level every day and ensure that the oil level is between the lowest and highest lines.

Before starting the hydraulic motor, make sure that the flow control lever is in the closed position.

The magnetic attraction must be turned on first and then the hydraulic pressure must be turned on

5. Smooth device of surface grinder

As the lubricating oil, use the rail lubricating oil with a viscosity of No. 32.

Check 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.

The lubricating grease is added regularly according to the regulations.

6. Left and right mechanism of surface grinder

Stop adjusting 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 dust box filter must be cleaned every two weeks.

The cold water tank must be cleaned once a month.
