Toodle Green spindles are driven by mist (lubricated air). They provide for very high rotation speeds while maintaining perfect run-out values.

TGC1312 (TG131) is designed to machine the workpiece top surface and perform milling, drilling, chamfering and engraving. For those machines equipped with through main spindle mist, Toodle Green 131 requires no machine adaptations, it fits into standard – sealed – tool holders, and several Toodle units may be applied into the machine magazine during the machine set-up. For all other machines, an air hose may be adopted externally via a dedicated tool holder.

The Toodle Green spindles provide for significant cost reductions, including:

Longer tool life
Shorter machining times
Longer main spindle life
Freeing machine to perform other tasks

Diagrams

Rotation Speed Vs. Air Pressure

This chart illustrates the logarithmic nature of the rotation
speeds measured at different pressure levels.
The formula displayed within the chart can be used to
calculate the rotation speed at any pressure level.
The curve is relates to average values. The actual results lie
within a small variance from the curve.
The rotation speed levels shown here are the no-load speeds
(i.e. no torque acting upon the shaft).

Torque Vs. Rotation Speed

This chart illustrates the relationship between the torque and
the actual rotation speed.
Notice that by definition, maximum torque occurs at zero
rotation speed resulting in no power. Likewise, at maximum
rotation speed there is no available torque, therefore
producing zero power.

Power Vs. Rotation Speed

This chart illustrates the parabolic relationship between output
power and rotation speed at different pressure levels. Notice
that there is no power available at zero and at maximum
rotation speeds.
This chart illustrates that any external load will cause a
reduction in speed; the more power demanded, the greater
the speed reduction. To the right of the peak lies the working
area of the spindle, the peak being its limit. The Toodle will stop
rotating should the power exceed “Max Power”.
