Target Applications and Industries
SPINJET spindles can be used for applications
requiring tool shanks of up to 6 mm and cutting
diameters of up to 3.5 mm. They can be applied
on a variety of applications at workshops owning
CNC machine tools with a spindle capacity of up to
15K RPM and coolant through the spindle with a
minimum pressure in the range of 20 to 40 bars.

The spindles are an ideal solution for the growing Productivity Booster
demand for finish and semi-finish operations on a The coolant-driven spindles lead to a significant
wide range of processed materials in the die & mold widening of the application range on medium /
industry, as well as high-precision machining of large machine tools and thus help to improve their
products for the aerospace and medical industries. productivity, provide higher efficiency, minimal setup
time, decrease machining time and reduce costs.
