Cooling lubricants – what to do in the event of a long production stop?
Even when the machines are not working, the chemistry and microbiology in your cooling lubricant remain active. The emulsion is often no longer circulated and there is no more refilling. All of these can cause significant problems such as bad odor, corrosion in the machine tools, and unstable emulsion. You must therefore decide whether you want to maintain the cooling lubricant during the production stop or whether you want to use the time to dispose of the old cooling lubricant, clean your machines and prepare them for future production.
Two options – maintain or dispose of
Water-miscible cooling lubricants cannot simply be left to their own devices. They must be regularly monitored and maintained to ensure the stability of the emulsion. Cutting and grinding oils do not require any special precautionary measures. However, the production stop can be a good opportunity to clean the machines and fill them with fresh oil.
The following points help to decide whether the cooling lubricant should be maintained or disposed of:
- Current condition of the KSS
- Age (service life) of the cooling lubricant
- Tank volume
- Length of the break
- Available employees

Maintenance of water-miscible cooling lubricants
It is crucial to properly monitor and maintain the water-miscible cooling lubricant during a production stop. For detailed instructions see downloads below or our online video tutorials .
The most important measures are:
- Concentration : Must be at least 8%. This guarantees sufficient pH buffer to keep the emulsion stable.
- pH value : make sure it stays within the recommended range.
- Circulation : circulate the emulsion for at least 30 minutes every day.
- Skimmer : let him run. If there is no skimmer, remove the floating tramp oil manually from time to time.
- Chip conveyor : run it daily before starting the circulation to remove chips and debris that collect on the floor

Machine cleaning
water-miscible cooling lubricants
If the production stop is a good opportunity to dispose of the old cooling lubricant, then a thorough machine cleaning is essential so that the new emulsion is not immediately contaminated again. The video shows you step by step how to clean and refill your machines. In the download area below you will also find a PDF with detailed instructions.

cutting and grinding oils
Even if cutting and grinding oils don’t require any special precautions, stopping production can be a good opportunity to clean your machines and refill them with a new oil – something you’ve wanted to do for a long time but never had the time to do so. Even with oils, it is imperative to clean the machines thoroughly to prevent contamination of the fresh oil. The video shows you step by step how to best do this. In the download area below you will also find a PDF with detailed instructions.
