Area of Application
A joint feature of partial-flow and full-flow central systems is the
fact that they are coupled to a number of machine tools. A pump station
is placed at or next to the machine leading the polluted liquid to
the central system via a pipe system.
Function
The filtration itself on a partial-flow system is effected via a band
filter with the traditional paper cloth.
The filtering of cooling/lubricating agent in a partial-flow system
typically covers 6-10% of the total liquid volume in the sump of
the machine tools.
When the filtered liquid has entered the central system, the liquid
is taken round a labyrinth system for 20-30 minutes so that the oil
molecules are allowed time to come to the liquid surface after having
been smashed by the centrifugal pumps of the CNC machines. Slide and
leak oils, if any, are collected in a special oilseparation system
before the liquid is led back to the machine tools. The process
runs continuously.
Benefits
- Prolonging the edge life of the tools.
- Less wear and tear of the machines.
- Filtering the surface liquid continuously.
- Always the same liquid level on processing machines.
- Prolonging the tool life of the process liquids.
- Fewer production breaks.
