Coolant-driven high speed compact spindle

Productivity quadruples due to spindles that rotate at high speed with coolant pressure

Features

1. Coolant-driven HSM 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 as an energy source to rotate a turbine at high speeds.
• Strong coolant jet flow provide extended tool life and machining stability.

 

2. Energy saving

• Tools rotate only with coolant pressure, and the machine spindle is idle while SpinJet is in operation.
Note: The main machine spindle should be stationary while the SpinJet spindle is mounted on the machine.

3. Wireless RPM monitoring system

• SpinJet is equipped with an online speed display system, monitoring the actual cutting tool rotation speed during machining.
