Related knowledge of CNC surface grinder operation

One type of grinder mainly uses the grinding wheel to rotate and grind the workpiece to achieve the required flatness. According to the shape of the working table, it can be divided into two types: rectangular working table and round working table. The main parameter of the rectangular working table surface grinder is the working table width. And the length, the main parameter of the round table surface grinder is the diameter of the working table. According to the different shaft types, it can be divided into horizontal shaft and vertical shaft grinder.

Operating instructions for surface grinders

1: Surface grinder positioning

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: Surface grinder wheel

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

Prevent the use of 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 feed 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: Surface grinder hydraulic equipment

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, and then replace it once a year. The oil tank must be cleaned together.

Check the hydraulic oil level every day. The oil level should be between the low and high 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: Surface grinder lubrication equipment

The lubricating oil uses the guideway lubricating oil with a viscosity of No. 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 smooth every week to prevent the guide rail from losing oil.

It is recommended to clean the fuel tank every three months.

Lubricating grease should be filled regularly according to the regulations.

6: Left and right organization 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. (This article applies to manual models)

7: Surface grinder flushing and dust collection equipment

The dust box filter must be cleaned every two weeks.

The cold water tank must be cleaned once a month.

Prevent the use of air guns to clean the surface grinder.
