Iscar has developed the SpinJet, a coolant driven high-speed spindle. The range has been specifically
designed for use with small diameter tools on low rpm machine tools and is suitable for semi-finish and finish machining applications such as milling, drilling and grinding.
The system utilises the machine tool’s existing coolant supply, driven by a high pressure pump (minimum 20 bars) as an effective energy source to rotate an integral turbine at speeds up to 40,000 rpm.
The device is not intended to replace a machine’s spindle, but rather to upgrade existing machines. The system is said to increase productivity by up to 65 percent when compared to machining with a machine’s existing low rpm spindle.
