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)
