Operating the central lubrication system
The CNC machine is equipped with a central lubrication system. This option is used to "manu-
ally" set the supply of the oil quantity. During operation the supply positions are automatically
supplied with oil in regular intervals using a time measuring instrument.
The lubricating system is used to maintain an oil film on the slideways, the bearings, the ledges
and the ball screws and to reduce their wear.
In case of a failure or a fault in the central lubricating system a stick-slip effect may occur. This
effect describes the jerky sliding of solids moving opposite one another. For instance: creaking
doors and rattling windscreen wipers.
