Coolant lubricant treatment system

Cleaner cooling lubricants and more stable processes

Cooling lubricants lose quality over time – due to particles, oil residues and biological contamination. This is precisely where KÖBO ECO>PROCESS cooling lubricant treatment systems come in: They keep emulsions stable, reduce the load on machines and improve the conditions for consistent machining results.

Cooling lubricant preparation

The key to process reliability

Coolant lubricant treatment systems are a central element in modern production. They ensure that cooling lubricants retain their physical and chemical properties over long periods of time. The continuous removal of solids, oil impurities and biological contamination as well as controlled temperature control of the cooling lubricant is crucial in order to keep machining processes constant and avoid quality defects.

Systematic preparation and temperature control not only improves the process reliability and service life of tools, but also the overall production quality. At the same time, the need for manual intervention is reduced, downtimes are avoided and compliance with operational environmental regulations is made easier – a decisive advantage in an increasingly automated production environment.

Challenges in the use of cooling lubricant

In modern manufacturing processes, companies are faced with the challenge of keeping cooling lubricants permanently efficient. Without systematic treatment, there are a number of problems that have a direct impact on productivity and quality. Typical challenges are

Especially with increasing production complexity, stable and automated solutions are required to master these challenges in the long term.

Coolant lubricant treatment system from KÖBO ECO>PROCESS

KÖBO ECO>PROCESS offers a wide range of treatment systems that are precisely tailored to the respective requirements – from individual processing stations to fully automatic central systems. Depending on the application, separators, pressure belt filters, vacuum belt filters or hinged belt filters are used. All systems can be modularly expanded and flexibly integrated into existing production lines. This results in tailor-made solutions that precisely match the production environment – robust, easy to maintain and powerful.

Filter system type	Description
Pressure belt filter	The pressure belt filter is a fully automatic filter for cooling lubricants that is fed discontinuously with contaminated cooling lubricant. Under overpressure, the cooling lubricant flows through a filter medium – either a circulating or reversing belt or a fiber fleece. The cleaned cooling lubricant then flows into a clean container and is available for production again. The retained dirt cake is blown dry in the filter and automatically discharged for chip disposal.
Vacuum belt filter	The vacuum belt filter continuously cleans cooling lubricants and also acts as a central collection container for the cooling lubricant circuit. A suction chamber underneath the filter belt generates the necessary negative pressure to draw the contaminated cooling lubricant through the filter medium. The cleaned cooling lubricant is extracted from the lower chamber of the filter by filter system pumps while the dirt cake is discharged at regular intervals. A separate regeneration tank ensures a continuous supply to production during the discharge process.
Folding belt filter	As a special form of pressure belt filter, the folding belt filter is particularly suitable for applications with lower throughput rates and for secondary filtration of precoat filter systems. Here too, the cooling lubricant is pressed discontinuously with overpressure through a circulating filter medium or fiber fleece. The cleaned cooling lubricant is then fed into a filter container, the dirt cake is dried and automatically discharged. The folding belt filter impresses above all with its robust and compact design.
Precoat filter	The precoat filter enables particularly fine cleaning of the cooling lubricant. First, a filter aid such as cellulose or diatomaceous earth is applied to the filter elements, which forms a permeable filter layer. The contaminated coolant is then continuously pressed through this medium and finely filtered. Once a defined level of contamination has been reached, automatic backwashing takes place to regenerate the filter unit. This technology is particularly suitable for secondary filtration in high-precision applications.
Chip separator	The chip separator is used to pre-filter coarse chips and solids from the cooling lubricant in order to relieve downstream filter systems. The contaminated cooling lubricant passes through a rectangular steel tank with an integrated scraper conveyor. Coarse chips and sediment settle at the bottom and are automatically discharged via the scraper conveyor for chip disposal. Optional slotted screens or overflows increase the separation capacity. The pre-cleaned cooling lubricant then enters the next filtration stage.

Advantages of a coolant preparation system

Extended service life of cooling lubricants

Continuous filtration effectively removes particles, abrasion and other impurities from the cooling lubricants. This extends the service life of the fluids, which significantly reduces replacement costs. Not only do you save on the cost of replacing the fluids, you also help to reduce the amount of waste.

Optimized production processes

Cooling lubricant treatment systems ensure constant and reliable cleaning of the cooling lubricants, which leads to a significant reduction in friction in processes such as cutting, grinding and forming. This not only increases the efficiency of your machines, but also the quality of the machined products.

Improved heat dissipation and cooling

Clean cooling lubricants help to optimize heat dissipation during production. In addition, uniform temperature control is ensured, which improves machine cooling, prevents overheating and leads to resilient production. This increases the service life of your machines and ensures consistent production quality.

Less wear and tear

Regular cleaning of the cooling lubricants reduces the accumulation of dirt and particles that lead to increased wear of tools and rollers. This increases the service life of the tools and reduces replacement costs, as repairs and replacement purchases are required less frequently.

Efficient removal of impurities

Cooling lubricant treatment systems reliably remove the finest particles and metallic abrasion from the cooling lubricants, which improves product quality and machining precision. Clean lubrication ensures uniform machining and prevents surface defects that occur with insufficient filtration.

Sustainable recycling of valuable materials

Our coolant treatment systems help to recycle valuable materials such as oils and metal shavings by filtering the fluids so that they can be reused. This sustainable practice not only reduces operating costs, but also supports your environmental goals by reducing waste and using fewer resources.
