High Pressure Coolant (HPC)
Jet Spindle

Exclusive HPC/HSM Jet Spindle Technology!

Introducing the only coolant-driven, auxiliary high-speed spindle that delivers increased power using the machine’s own HIGH PRESSURE coolant supply. Now you can take advantage of machines with high pressure capability for better machining results, longer tool life and increased efficiency. The HPC Jet Spindle’s patented design suits the growing number of machines in the market that use a high pressure narrow beam coolant jet directed to the cutting tool, and high pressure coolant deep drilling tools. Fields of application include milling, drilling, chamfering, grinding, and more.

High Speed / More Power / Greater Efficiency

High Pressure Coolant Driven Speed Increaser

  • Compact, robust, patented aux. HSM Jet Spindle specially designed for operation with high pressure coolant pumps
  • Max power output 1.5 Kw up to 50,000 Rpm
  • Ideal for finishing/semi-finishing applications using small cutters and grinding wheels
  • Plug & Play convenience – no wires or pre-installation
  • Integral wireless RPM readout sensor system (uses same Display Unit as the Jet Spindle)

Main Features of the HPC Jet Spindle:

  • Optimal pressure range from [30 to 70] bars with available power of 0.35 to 1.5 [Kw]
  • RPM range 25 to 50 [Krpm] with reinforced spindle bearing construction for improved load capacity and longer life
  • Moderate flow rate of 16-22 L/min
  • Single-handed operation, special design shaft lock key
  • 2.4Ghz speed sensor inside / Wireless RPM Display Unit / SmartHUB + App
  • Works with water-based emulsion or cutting oil, viscosity up to 20 [Cp]
  • Standard ER11 collet chuck, less than 2 micron run-out (T.I.R)
  • Compatible with most commonly used machine adaptors

Wireless RPMs Monitor & Display
The HPC Jet Spindle is equipped with a wireless display system, allowing real-time monitoring of the rotation speed during machining. The spindle housing is fitted with an integral wireless transmitter that sends RPM data to the display unit (receiver) located outside of the machine.tjs_hpc_monitoringAccessories: Standard clamping accessories are not sufficient to ensure accuracy at higher RPMs. Check out the appropriate spindle accessories to ensure optimum operational accuracy.
