Frequently asked questions

An NSK High Speed Spindle is an integrated motor/spindle that does not use machine spindle rotation. Spindle Speeders are driven by the machine spindle with gears to increase or decrease tool rpm.

NSK High Speed Spindles have no gears. Gears generate heat, vibration and thermal growth which are all deterrents of high speed spindles.

1 Watt = .00134 Horsepower ex. 350 Watts = .469 H.P

Any time a tool or collet is being replaced, it is recommended to remove the collet and collet cap, then clean them as well as the spindle taper with an alcohol swab to remove any cutting debris. This will help maintain spindle accuracy and improve longevity.

No. All sales are made through NSK’s authorized distributors. An NSK Manufacturers Representative can put you in contact with your local distributor.

NSK Air Line Kits atomize, providing an oil vapor to the spindle and motor, providing lubrication, cooling and purging of the spindle and motor.

Yes. The viscosity and composition of the Superla 9 Oil is ideal for atomization.

Although motor speed can be reduced by lowering the air pressure, it is not possible to know what the actual speed is, and power will also be lost exponentially by reducing air pressure.

The possibility of either too much oil or insufficient oil will cause excess bearing friction and heat, as well as premature motor vane wear.

Too much oil will flood the motor and spindle bearings. Once the bearings clear themselves of the oil, the RPM will increase. More oil again will cause the rpm to decrease, causing the RPM to constantly fluctuate.

The length of the input side of the air hose is not important. But, the exhaust hose length must be kept to the factory provide length in order to correctly provide the removal of back pressure.

A small amount of Dry Air is required to provide cooling and purging for the motor and spindle.

The versatility of an Electric System far outweighs that of a Pneumatic System. It is a closed loop system that will put more power to the motor to maintain RPM and torque; it is variable speed to meet the demands of more applications and offers more power and speed. Pneumatic motors are fixed speed, require lubrication and are lower rpm.

No. Only one motor can run at any given time. A separate control unit will be required to run a second spindle simultaneously.

Yes. All NSK motors have an IP-57 Rating. Coolants should however be directed at the cutting tool, not directly on the motor/spindle.

When an application requires a lower RPM than a high speed spindle can supply, and still provide torque and power. A Reducer is used. As an example, a 1:4 Reducer will only provide 25% of the motor speed (maximum motor speed 30,000rpm), but 4 times the torque. This allows the ability to use larger tools at lower speeds.

Yes. The NSK control has a 25 Pin din Connection for many several +24V analog Input and Output functions to communicate with the CNC control.
