Description

Aerosol booster with piston pumps and PRO-CYCLON® technology to produce fine oil-air mixtures.

Main application range:

Internal MQL for single channel rotary union, middle and upper rotational speeds.

Operating principle:
In the case of internal lubrication only the finest drops are able to get through as the centrifugal forces inside the spindle eject the bigger oil droplets. The Centermat® C30 utilizes this effect through its use of PRO CYCLON® technology. Coarse droplets are separated in the Centermat® C30 early on and transported back to the supply reservoir, thereby minimizing consumption. The smallest droplets in the µ-range that remain form a fine, stable aerosol Mixture which is transported to the drill holes in the machine tool all the way through the feed tube, rotary union and spindle.

Product versions:
The basic version C30/1 provides one spray nozzle in the spray chamber and is designed for tools with a total channel cross section of 1.0 to 10 mm2. Suitable for applications where the tools have similar channel cross sections in the above mentioned range.

The full version C30/1 V7 provides two independent spray nozzles in the spray chamber and is designed for tools with a total channel cross section of 1.0 to 120 mm2. Suitable for applications where the tools have a wide range of total channel cross sections. The additional air can also be switched on/off separately and this can be used for particularly large tools or for blowing-out.

For applications with a total channel cross section of 0.2 to 3.0 mm2 a special mini spray nozzle is available on demand.

At full version C30/1 V7

Two pneumatically driven, finely meterable piston pumps to feed two spray nozzles in the spray chamber.

– Piston pumps with FPM seals, manually adjustable with scale indicator, volume 0 – 0.03 ml per stroke.

– Spray nozzles with dedicated air valve with manometer (0 – 10 bar) to set spray air quantity.

– Dedicated air valve with manometer (0 – 10 bar) to set quantity of additional air.

– Ventilation unit integrated on the side of the pump block.

– Frequency generator for pump pulse, manually adjustable 0 – 90 stroke min-1.

– Manometer (0 – 10 bar) in the door front to indicate reservoir pressure.

– Pneumatic pressure switch to switch off nozzles in case of pressure build up including visual display unit in the door front.

– Automatic ventilation valve with hand actuation.

– Coupler plug NG8 for compressed air supply to left side of housing.

– Air filter with integrated water separator and drainage opening on underside of housing.

– Robust, compact metal housing 500x300x210 with robust metal closer and door seal for dust protection and noise reduction, earthing pin, 4 mounting straps for wall mounting of the housing.

– Connection for feed tube with push-in coupler Ø12 on the upper side of housing.

Equipment: Reservoirs

– Aluminium reservoir, 1.5 litre inside housing with stopcock on the reservoir outlet.

– Float switch min (metal, potential-free, either NC or NO).

– Hand pump for filling the reservoir and funnel tube.

– Visual fill level display in door front.

Equipment: Drive
  • At basic version C30/1:One solenoid valve for the spray nozzle and the additional air together.
  • At full version C30/1 V7: Two solenoid valves for the two spray nozzles, one for the additional air.

– Each solenoid valve is 3/2 way (120 Nl/min) with auxiliary actuation (for occasional manual switching on/off). Coil with plug in 24V DC, 24V AC, 110V AC or 230V AC. Cable bushing on the left side of housing.

Equipment: Feed tube

Feed tube (PUN Ø12). Smallest bending radius 80 mm. Standard length 3,000, non-standard lengths up to 15,000 available on request.
