Milling spindle SpinJet

machiningcuttingspindle

Product overview

• Coolant-driven high speed compact spindle.
• Productivity quadruples due to spindles that rotate at high speed with coolant pressure.

Key phrase

• Coolant-driven high speed compact spindle for high productivity with small diameter tools on limited RPM machines.
• SpinJet utilizes the machine tool’s existing coolant supply, driven by a high pressure pump to rotate a turbine at high speeds; strong coolant jet flow provides extended tool life and machining stability.

Features

• Coolant-driven HSM spindle: SpinJet uses the machine’s coolant supply as the energy source to spin a turbine and rotate cutting tools at extremely high speeds while the main machine spindle remains idle when SpinJet is mounted.
  • Provides high speed machining capability even on machines with limited spindle RPM.
• Energy saving: Tools rotate only with coolant pressure, so the machine spindle remains stationary during SpinJet operation. Note: main machine spindle should be stationary while SpinJet is mounted.
• Wireless RPM monitoring system: SpinJet is equipped with an online speed display system to monitor actual cutting tool rotation speed during machining.
• Strong coolant jet flow: Extended tool life and improved machining stability due to high-pressure coolant flow through the spindle.

Holders & Accessories

• SpinJet holders (example holder models indicated on product page).
• SpinJet accessories (adapters and accessory sets for various expansion/adaption types).
