SpinJet is a new range of coolant driven, high speed spindles from Iscar designed for use with small diameter tools on low rpm machine tools.
Suitable for semi-finish and finish machining applications such as miling, drilling and grinding, the patent pending spindles use the machine’s existing coolant supply, driven by a high pressure pump (minimum 20 bars) as an energy source to rotate an integral turbine at speeds up to 40,000 rpm.
SpinJet isn’t intended to replace a machine’s spindle, rather, it’s intended to upgrade the existing machine and provide improved performance, faster machining, enhanced surface quality and extended tool life.
The system increases productivity by 65 per cent when compared to machining with a machine’s existing low rpm spindle, says Iscar, adding that increased precision and excellent surface quality are achieved due to optimized machining conditions.
As the machine’s spindle remains idle while the SpinJet is in operation, energy savings are made. In addition, as a result of optimal cutting conditions and strong coolant jet flow, tool life is considerably extended.
‘Plug & play’ installation on existing machines is made easy, as no adaptation is required. The system is equipped with an online speed display system, monitoring the actual cutting tool rotation speed during machining. The direct wireless rotation speed display uses 2.4 GHz radio frequency transmission and has a range of up to five meters, while an externally powered display enables reading of all SpinJet systems being used on the machine.
The new spindles are an ideal solution for the growing demand for finish and semi-finish operations across a wide range of processed materials in the die & mold industry. In addition, they provide an answer to the requirements for the high precision machining of products within the aerospace and medical industries.
