Your advantages
- Continuous lubrication – all lubrication points are supplied automatically.
- Lower wear – less friction, longer component life.
- Minimum downtimes – higher machine availability.
- Cost efficiency – lower lubricant consumption & maintenance costs.
- Sustainability – resource-saving & environmentally friendly.
Regulations and what they mean
On a machine tool the lubrication points are small, numerous and hard to reach: linear guides, ball screws, spindle bearings, turrets. Exactly this profile makes automatic central lubrication the rule here, not the exception.
| Machine characteristic | Consequence |
|---|---|
| many points with small demand | individual greasing would be disproportionate; metering in hundredths of a cm³ per cycle |
| motion during operation | lubrication must run while the axis moves — not at standstill |
| enclosed working area | the points are unreachable during operation |
| metalworking fluid nearby | metered delivery limits tramp-oil input |
| accuracy requirement | an even film prevents stick-slip in the guide |
Stick-slip is the real argument
At very slow feeds a guide can judder when the film breaks in places: static friction builds force, sliding friction releases it abruptly — visible as chatter marks on the surface. Frequent small doses keep the film continuous; one large dose at long intervals does not. What matters is therefore the allocation per point, solved by progressive dividers, single-line systems or a multi-outlet pump.
A system that fails silently is noticed on a machine tool only when the guide has play. A pressure switch proves pressure build-up, a cycle sensor the actual indexing of the divider — only that makes it monitored lubrication.
