High-pressure system combiloop CL2G Next Generation
FOR CONTINUOUS USE UP TO 120 BAR
Mobile, compact high-pressure unit for daily use – from sliding-headstock lathes to machining centres; from cutting oil to emulsion; from brass to gold.
Depending on the medium used, the appropriate high-pressure pump technology is at work inside:
- Oil: robust gear pump for high pressure up to 120 bar, 16 l/min flow rate
- Emulsion: frequency controlled screw pump designed for stable 70 bar in water-based cooling lubricants, up to 20 l/min
The 3-chamber tank system with 150 μm pre-filtration and the 140-litre clean tank promote stable, reliable operating conditions. The protected dirt pre-separation, combined with the easily accessible, washable wire mesh elements forms the first filtration stage. Fine filtration (25, 40, 60 μm) is performed by a single filter or the optional double changeover filter – perfect for continuous use – and washable or burn-out filter elements.
Orange warning at 80% filter capacity, Industry 4.0 features and optional ultra-fine filters (up to 6 µm per high-pressure line) increase process reliability and service life while reducing operating costs.
Perfect as an OEM or retrofit for: Benzinger, Biglia, Brother, Bumotec (Starrag), Chiron, Citizen, DMGMORI, Fanuc, Hermle, Index, Kitamura, Manurhin, Mazak, Miyano, Nakamura, Okuma, Pfiffner, Star, Tornos, Traub, Tsugami, Willemin-Macodel, and many more.

| Function and description of the combiloop CL2 G Next Generation high-pressure system |
| The combiloop CL2 G Next Generation high-pressure system draws the contaminated cooling lubricant from the tank of the machine tool via an integrated transfer pump and separates it using the patented pre-separation system of the 3-chamber tank. It then fills its own clean tank. Next, the high-pressure pump draws the cooling lubricant, which has been pre-cleaned to 150 µm, from the clean tank through a fine filter and supplies the cleaned cooling lubricant to the tools of the machine tool via the controllable high-pressure connections. Up to 10 controllable high-pressure connections can be selected via M functions in the machine programme. The operating pressure can be set manually on the high-pressure system or, depending on the configuration level, directly from the machine control system. An electrical signal triggers an alarm if the filter becomes dirty. To clean the filter, the machine must either be stopped and the filter element replaced or cleaned, or if a double-switching filter is used, it can be switched from filter 1 to filter 2 without stopping the machine. A specially developed pre-warning system emits a yellow warning signal when around 80% of the filter capacity is exhausted in order to organise the work process without necessarily triggering a machine standstill. Whether single filter or double switching filter, the high-pressure system can also be equipped with a frequency converter to operate the system gently and energy-efficiently. For safety reasons, a flow monitor is installed to check whether medium is flowing and can cause the machine to stop immediately if the tools become blocked. Effective spindle flushing via the high-pressure system is also possible using a pressurised high-pressure connection. |
