Description

Piston pump system with hybrid nozzle for fine oil-air mixtures.

Main application range:

Internal MQL for single channel rotary transmission leadthrough, lower and middle rotational speeds.

Operating principle:

The proven piston pumps of the Toolmat® T70 provide for an exactly selectable flow rate. The spray grade can be determined via the spray air. The saturation of the mixture can be adjusted via the casing air. In the Vario3 and Vario7 versions, 3 or 7 pre-settable oil quantities can be selected.
The hybrid nozzle is principally delivered flush-mounted to the 3/8” thread connection at the end of the feed tube. So it possible to mount the Toolmat® T70 at any appropriate connection.

If possible, the hybrid nozzle may project out of the 3/8” external thread connection for a certain length so that the body (Ø5mm) of the hybrid nozzle extends through the axial rotary transmission leadthrough into the spindle. This more complex installation pays off by better spraying results thanks to the shorter distance to the cooling channel outlet.

Adjustability

  • Swept volume of the pump (manual)
  • Clock frequency of the pump (manual)
  • Quantity of spray air (manual)
  • Quantity of casing air (manual)
  • Switch on/off using actuation control drive (electric, pneumatic or manual)

– Pneumatically driven, finely meterable piston pump with double flow volume (2DF) with FPM seals, manually adjustable volume dial (0 – 0.06 ml per stroke) . Vario3 and Vario7 variations have piston pumps with simple flow (0 – 0.03 ml per stroke), individually adjustable.

– Ventilation unit integrated underneath the pump module.

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

– Dedicated air valve to determine spray air quantity.

– Dedicated air valve to determine casing air quantity

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

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

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

– High grade push in/screw fittings / pneumatic tubes.

– Stable, compact metal housing (250x250x210 or 300x250x210) with robust metal closer and door seal for dust protection and noise reduction, earthing pin.

– Connection for feed tube on the left side of housing.

– Component labelling in accordance with the designations in the pneumatic connection diagram.
