Spindle Selection

Two enhanced performance HSM Jet Spindle models ensure you’re getting the optimal solution for the widest range of machining applications using small cutting tools.The GreenJET Model and the HPC Model (high pressure).
Spindle selection is based on the following parameters:

  • Machine coolant pressure
  • Coolant flow rate
  • Required rotational spindle speed
  • Cutting tool diameter recommended:
    0.4mm – 4.0mm (dependent upon the application)

GreenJET CNC Machine Prerequisites:

  • Coolant flow through the main CNC machine spindle
  • Min. coolant pressure, at main spindle outlet: 20 bar (290 psi)
  • Max. coolant pressure, at main spindle outlet: 40 bar (580 psi)
  • Minimum flow rate: 12 L/min (3.17 Gal/min.)
  • Coolant filtration level: Max. 100 μm
  • Coolant pressure measured at spindle inlet

HPC Model CNC Machine Prerequisites:

  • Coolant flow through the main CNC machine spindle
  • Min. coolant pressure, at main spindle outlet: 15 bar (218 psi)
  • Max. coolant pressure, at main spindle outlet: 70 bar (1020 psi)
  • Minimum flow rate: 16 L/min (4.23 Gal/min.)
  • Coolant filtration level: Max. 100 μm
  • Coolant pressure measured at spindle inlet

Adaptors & Clamping

Modular Jet Spindles with
Built-in ER32 Collet

USING BT ADAPTOR MODELS: Internal diameter of the PULL STUD must be a min. of 4.0mm, to allow sufficient coolant pressure flow for proper Jet Spindle operation.
