Industrial coolant filter

Cooling lubricant filters for the machine tool industry

Filtration of cooling lubricants in the central supply systems of the machine tool industry is extremely demanding. Then, in addition to the actual KSS filtration, continuous care of the bath is required. Cooling lubricant filters must ensure a defined degree of cleanliness.

KSS filters for machines and systems

The quality of a cooling lubricant (KSS) influences the period of its usability and, thus, also the production costs. Because, for machines and systems for mechanical processing in the machine tool industry, constant operating conditions are a prerequisite for reliable and continuous operation. The cooling lubricant filter from BOLL & KIRCH not only assist in perfect function of the systems, but also enable economic and resource-saving operation.

Filtration of coolants

Cooling lubricant filters from BOLL & KIRCH can be integrated into all general configurations of the metalworking industry as a component without a problem. They then come into use when cooling lubricant is contaminated by the mechanical processing procedures – for example:

• systems for grinding and honing of engine and gearbox components
• during cold forming of metal by rolling, pressing, milling, drilling or cutting.
