Tungaloy has expanded its SpinJet coolant-driven, auxiliary high speed spindle series to include the HPC SpinJet line that utilizes coolant pressures of up to 7 MPa (70 bar, 1,015 psi).
Easily adaptable to the spindle of existing CNC machines, the SpinJet provides instant enhancements in machining performance using small diameter cutting tools. No additional machine purchase or modifications are required: the SpinJet utilizes the machine’s existing through-spindle coolant supply as a pressurized power source to drive the internal turbine for cutting tool rotation, eliminating the cost and nuisances of external air or electric power supplies. This feature gives the SpinJet a compact and smart design, allowing it to be stored 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.
In addition, the SpinJet includes a wireless display monitor giving operators real-time performance of RPMs for optimal cutting tool conditions according to actual rotational speed on the workpiece.
The new HPC SpinJet harnesses higher coolant pressures in a range of 4 to 7 MPa (40-70 bar, 580-1,015 psi), rotating the turbine as fast as 45,000 RPMs. With enhanced internal turbine and bearings for higher torque output, the HPC SpinJet can handle various rotating tools in up to 3 mm diameter.
HPC SpinJet boosts productivity when compared with conventional spindle setups. For example, with a conventional spindle setup, a small tool cutting process had to be done using another dedicated high speed spindle machine due to insufficient spindle rotation. HPC SpinJet will eliminate the need for workpiece transfer, thereby keeping the process chain intact for better machine downtime and operation efficiency.
Six new models, including TJSHPCBT40, TJSHPCER32, TJSHPCHSKA63, TJSHPCCAT40, TJSHPCC6 and TJSHPCST20 have been introduced.

- computer numerical control ( CNC)
computer numerical control ( CNC)
Microprocessor-based controller dedicated to a machine tool that permits the creation or modification of parts. Programmed numerical control activates the machine’s servos and spindle drives and controls the various machining operations. See DNC, direct numerical control; NC, numerical control.
- coolant
coolant
Fluid that reduces temperature buildup at the tool/workpiece interface during machining. Normally takes the form of a liquid such as soluble or chemical mixtures (semisynthetic, synthetic) but can be pressurized air or other gas. Because of water’s ability to absorb great quantities of heat, it is widely used as a coolant and vehicle for various cutting compounds, with the water-to-compound ratio varying with the machining task. See cutting fluid; semisynthetic cutting fluid; soluble-oil cutting fluid; synthetic cutting fluid.
