Tungaloy SpinJet HPC Uses Coolant Pressures up to 7 MPa
Tungaloy’s new HPC SpinJet line adds high-pressure, high-speed spindle capability to the company’s coolant-driven spindle series.
Tungaloy has expanded its SpinJet coolant-driven, auxiliary high-speed spindle series with the HPC SpinJet line, which utilizes coolant pressures of up to 7 MPa (70 bar, 1,015 psi).
Tungaloy says the SpinJet is easily adaptable to the spindles of existing CNC machines, and enhances machining performance with small-diameter cutting tools. SpinJet spindles require no additional machine purchases or modifications, instead utilizing the machine’s existing through-spindle coolant supply as a pressurized power source to drive the internal turbine for cutting tool rotation — thus eliminating the need for external air or electric power supplies. The resulting flexibility allows users to store the SpinJet in a machine’s ATC or tool magazine when it is not being used and installed on the main spindle, as with any other standard tool.
SpinJet purchases include a wireless display monitor that shows operators real-time RPM performance for optimal cutting tool conditions, according to actual rotational speeds on the workpiece.
The new HPC SpinJet harnesses higher coolant pressures in a range of 4-7 MPa (40-70 bar, 580-1,015 psi), rotating the turbine as fast as 45,000 RPM. The spindle line’s enhanced internal turbine and bearing designs support higher torque output, allowing the HPC SpinJet to handle rotating tools up to 3 mm in diameter.
Tungaloy says the HPC SpinJet can complete small tool cutting processes that conventional spindle setups could not handle due to insufficient spindle rotation. Th HPC SpinJet’s capability eliminates the need for workpiece transfer, thereby keeping the process chain intact for better machine downtime and operation efficiency.
New HPC SpinJet models include TJSHPCBT40, TJSHPCER32, TJSHPCHSKA63, TJSHPCCAT40, TJSHPCC6 and TJSHPCST20.
