GJET

The GJET spindle is our HSM Jet Spindle Model.  Combining speed with power, GJET is your best option for working with small tools. GJET is a patented robust spindle speed increaser design that uses the machine’s existing coolant or cutting fluid supply as a pressurized energy source (20 to 40 bars), rotating a turbine in the range of 35,000 – 55,000 RPMs.

This compact unit fits a wide range of CNC machines, is ATC / turret mountable, and an ideal solution for semi-finishing and finishing applications using small-diameter cutting tools; milling, drilling, thread-milling, engraving, chamfering, deburring, grinding, and more.

The HSM Jet Spindle is equipped with a real-time, wireless RPM transmitter and monitoring display system to optimize performance. Refer to the Operating Conditions Guidelines for this HSM Jet Spindle.

  • Coolant pressure is measured from the spindle inlet
  • Rotational spindle speed is based on coolant pressure and flow rate
  • Spindle speed may vary up to 7%
