Valve grinding machine


Valve grinding machines are machine tools that use abrasives to grind the surface of valves. Most grinding machines use high-speed rotating grinding wheels for the grinding process. A few use other abrasives such as oil stones, abrasive belts, and free abrasives for processing, such as honing machines, superfinishing machines, belt grinders, grinding machines, and polishing machines.

Maintenance of the lubrication unit


Inspection and discharge of the lubrication tank

The bottle of the lubrication mailbox collects sewage. The bottle should be filled with oil at all times. If sewage appears, the glass bottle should appear to separate water and oil, with the water at the bottom. To clean up contaminants, turn off the equipment, place a suitable collection container under the bottle piece, loosen the discharge plug and allow the water to drain out. Once the water has been drained, retighten this drain plug. The adjustment valve is preset at the factory and cannot be adjusted.

Check and refuel

The oil level should be kept between the highest and lowest marks of the observation gauge. To refuel please turn off the unit, remove the cover, fill the oil to the top mark of the observation gauge and drain the tank by loosening the drain plug.

Inspection and replacement of the lube oil filter

The pressure gauge pointer should be in the green area of the gauge. When the filter cartridge is clogged, the pressure rises and the pointer moves to the red area. If the pointer is in the red area, the filter cartridge should be replaced.

Perform filter cartridge replacement according to the following steps

1. Turn off unit  2. Loosen the cartridge counterclockwise  3. Remove the cartridge and dispose of it   4. Replace the filter cartridge with a new one.
