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. Italy The company has specialized for over thirty years in the design and manufacture of high-precision plasticizing screws and cylinders. To maintain the quality of its CNC machining and the reliability of its processes, the company needed a filtration system that would ensure coolant stability while effectively managing oil mist. The existing system no longer ensured the desired continuity: variable contamination of the bath, machine downtime for maintenance, complex sludge management, and suboptimal environmental conditions in the department. The goal of the project was not simply to replace a filter, but to design an integrated CNC filtration system capable of:

• Control oil mist and improve the work environment by maintaining high standards of cleanliness and fluid performance, and stabilizing the level of coolant contamination

• reduce downtime

• improve the efficiency of sludge management

Integrated System Architecture

Self-cleaning main filter

The heart of the system is the self-cleaning filter Spin 1100, which ensures continuous and reliable filtration without the need for consumable filter media. With a flow rate of 500 l/min, a permanent filter cloth made of AISI 304 stainless steel and a filtration rating of 50 µm (average), the Spin the refrigerant contamination level stable even as the particulate load varies.

Magnetic separator

Upstream of the fine filtration, the magnetic separator Kalamit The 500, made of AISI 304 stainless steel, continuously removes ferrous particles, 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 conveyed to a sludge-dewatering screw, which recovers up to80% of the liquid trapped in the process sludge. This results in three direct benefits: reduced disposal costs, refrigerant recovery, and greater sustainability of the production process.

2,600-liter cooling tank with oil separator

The cooling tank from 2,600 liters, 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

Rounding out the system is the exhaust fan Kube 1,200 with post-filtration HEPA H13 It manages 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 a complete system where every component plays a specific role. The Spin ensures continuous filtration stability, the Kalamit 500 protects the process by removing ferrous particles, the sludge-drying screw conveyor recovers coolant and reduces waste, and the 2,600-liter tank with oil separator keeps the bath clean, Easyband continuous overflow, and the Kube 1200 with HEPA H13 controls oil mists. For CNC workshops seeking to combine process stability, efficient sludge management, and improved air quality in the workshop, this system model represents a benchmark solution, designed to last and grow alongside production
