5.Rotary shaft system

(1) Air bearings refer to bearings that use gas as lubricant. They have extremely high rotational accuracy, so they are often used in precision testing instruments as the measurement benchmark for precision rotational measurements.

(2) The principle of air bearings is that after the pressurized air enters the air cavity of the bearing sleeve, it forms an air film with the shaft core through the throttle. The air film suspends the shaft core so that there is no mechanical contact between the shaft core and the shaft sleeve. The air cavity has a homogenizing effect on the processed shapes of the shaft sleeve and shaft core and improves mechanical accuracy. Therefore, this type of bearing has extremely high rotational accuracy, low rotational friction, good low-speed creep, and long-lasting accuracy.

(3) The air flotation spindle adds an air chamber, so that when the air flotation spindle measures the workpiece, it is less affected by the air source, expands the weight range of the measured object, and improves the stability of the instrument.

(4) The last process of each core part is pure manual grinding. Strict grinding technology and exquisite grinding technology ensure the accuracy of spindle rotation.

6.Precision oil removal device, inlet air pressure display system, air pressure alarm system

(1) Using Taiwan’s precision oil removal device, it can effectively filter oil in the air, thereby preventing the precision spindle from being scratched or rusted by impurities.

(2) The two-stage pressure regulating device can ensure that the inlet air source pressure is more stable, the air bearing runs more smoothly, and can improve the measurement repeatability.

(3) The inlet air pressure adopts an electronic display system to control the pressure range. When the air pressure is too low, the alarm device is activated and the measurement stops, effectively protecting the precision spindle.

7.mobile control unit

(1) The analog control unit independently developed by Kuehne + Nagel integrates commonly used control commands and can achieve rapid batch measurement without the use of keyboard and mouse, saving measurement time.
