If you work withCNCmachining centers for screws and plasticizing cylinders and have to manage coolant, swarf, and oil mist all within a single system, you know the problem: higher production means more contaminants and less control over the process and the work environment.
The MRS Italia Case
M.R.S. Italia is a company that has specialized for over thirty years in the design and manufacture of high-precision screws and plasticizing cylinders. To maintain the quality of its CNC machining and the reliability of its processes, the company needed a filtration system that would combine coolant stability with effective oil mist management.
The existing system no longer provided the desired reliability: fluctuating levels of contamination in the bath, downtime for maintenance, complex sludge management, and room conditions that could be improved.
The goal of the project was not simply to replace a filter, but to designan integrated CNC filtration systemcapable of:
- Control oil mist and improve the work environment
while maintaining high standards of cleanliness and fluid performance; stabilize the level of coolant contamination - reduce downtime
- improve the efficiency of sludge management
Integrated System Architecture
Self-cleaning main filter
At the heart of the system is the self-cleaning filter Spin 1100, which ensures continuous and reliable filtration without consumable filter media.
With a flow rate of500 l/min, a permanentAISI 304 stainless steelfilter screen, and a filtration rating of50 µm on average, the Spin a stable level of coolant contamination even as the particulate load varies.
Magnetic separator
Upstream of the fine filtration stage, theKalamit500 magnetic separator, made of AISI 304 stainless steel, continuously removes ferrous particles, thereby reducing the load on the drum filter.
This step improves the overall quality of the process fluid and reduces wear on CNC machine tools, increasing process stability over time.
Sludge Management
The sludge collected by the filtration system is fed into a sludge-pressing screw conveyor, which recovers up to80% of the liquidtrapped in the processing sludge.
This results in three direct benefits: reduced disposal costs, recovery of coolant, and greater sustainability of the production process.
2,600-liter cooling tank with oil separator
The2,600-liter cooling tank, made of reinforced carbon steel and featuring a sloped bottom, directs the sludge toward the collection points, preventing buildup and dead zones.
The integrated oil separator continuously removes foreign oils from the surface, keeping the coolant bath cleaner and more stable over time.
Oil Mist Control
To complete the system, theKube1200 fume extractor withHEPA H13post-filtration captures the oil mist generated by CNC machining. The Kube 1200 ensures high filtration efficiency, a cleaner work environment, and greater protection for operators and equipment.
The results
With this integrated CNC filtration system, MRS Italia has achieved:
- greater sustainability of the production process and improvement of the work environment
- significant reduction in downtime
- greater long-term stability of the refrigerant
- superior quality of high-precision machining
- reduced maintenance and disposal costs
Conclusion: A complete CNC filtration system, not just a filter
The solution developed for MRS Italia is not a single component, but acomplete systemin which each element plays a specific role.
The Spin ensures continuous filtration, the Kalamit 500 protects the process by removing ferrous particles, the sludge screw conveyor recovers coolant and reduces waste, the 2,600-liter tank with oil separator keeps the bath clean, Easyband continuity in overflow, and the Kube 1200 with HEPA H13 controls oil mist.
For CNC machine shops seeking to combine process stability, efficient sludge management, and improved air quality in the workshop, this system model is a leading solution, designed to last and scale alongside production
