Project Description
Toodle Blue spindles are driven by through-coolant or oil. They provide for very high rotation speeds while maintaining perfect run-out values.
TBV1304 is an adjustable angle Toodle, providing small footprint, simple, and affordable high rotation speeds.
The Toodle Blue spindles provide for significant cost reductions, including:
- Longer tool life
- Shorter machining times
- Longer main spindle life
- Freeing machine to perform other tasks
Diagrams

- 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 and equation relate to average values. The actual results lie within
a small variance from the curve. - The labeled “Water Pressure” may refer to any liquids with similar viscosity as
water (i.e. all types of emulsion/cooling liquid). - The rotation speed levels shown here are the no-load speeds (i.e. no torque
acting upon the shaft).

- This chart illustrates maximum and recommended output power levels
measured at different pressure levels. - The formula displayed within the chart can be used to calculate the output
power at any pressure level. - The max output power curve is meant as a reference only and should not be
used for an actual job. Working near this curve will put the spindle at risk of
operating failure and damages may result. - It is suggested to locate the job’s required output power close to or below the
“Recommended Output Power” curve, resulting in improved speed stability.

- This chart illustrates the relationship between the torque and the actual
rotation speed. - The formula displayed within the chart can be used to calculate the torque at
any 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.

- 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 spindle
will stop rotating should the power exceed “Max Power”.
