Centering Gauge Swing Type is an ultra-high precision 3D touch sensor (probe) with higher quality than that of Point Finder series! Repeatability is guaranteed. All model has a buzzer with it. Repeatability is ±0.25μm!! *This is the designated product for the machining center made by Okuma Corp. If you use Okuma's machining center, please let us know its model.

Repeatedly even with a 150mm stylus length accuracy ± 1μm guarantee (Patent No. 5133884）

Features of the Centering Gauge Swing Type

  • Centering Gauge Swing Type is the ultra-high precision 3D touch sensor (probe) with higher quality than that of Point Finder series.
    Use it for all kinds of measurements such as for reference position, inside/outside diameters, centering, angle, groove width, and height.
  • Supersensitive CT board is built-in the Centering Gauge Swing Type and it doesn't cause 'Chattering' phenomenon.
    　※Chattering: When the stylus touches to a workpiece, the LED flashes on and off
    　　because of the variation of both voltage and current occured by electrical resistance.
  • Thin workpiece is measurable because the contact pressure between the stylus and workpiece is lower.
  • It doesn't cause the triangle error.
  • Iron and nonferrous metal materials are measurable. It's unaffected by oil film.
    Use "Point Finder-i" [Internal Contact Type] for measuring metal and nonmetal materials such as plastic, wood, etc. →【Point Finder series】
  • Safety design enables the stylus swing toward X, Y and Z-axes directions and prevents the Centering Gauge Swing Type itself from breakage. Especially, swing width toward X and Y-axis is ±50mm !
  • All models have a buzzer. It beeps at the very same time when the stylus touches a workpiece and the LED emits.
  • With nonmagnetic stylus, magnetic force doesn't affect to the measuring.
    → Check the detail of 【Nonmagnetic Stylus】
  • Customized model with a connector (but no CT board) can take information as an external trigger code. However, the code is read out as analog signals, so it's neccesary to translate the analog signals into the digital ones.

Comparison between Swing Type and Point Finder [External]

Centering Gauge Swint Type is the 3D touch sensor with higher pricision rather than Point Finder [External Contact Type].
Use Point Finder-i [Internal Contact Type] for the measurement of metal and nonmetal materials such as plastic, wood, etc. → 【Point Finder series】

*1：'Repeatability' is a level to show the repeat accuracy of the standard stylus
　　when it returns to the original position.
*2：You can change the size of stylus instead of the standard one.

How to measure

Centering Gauge Swing Type is available to measure any position and angle

　　Centering Gauge Swing Type makes it possible to measure reference position, inside/outside diameters, centering, angle, groove width, and height. Those measurements are very important before the metal working.

　With Centering Gauge Swing Type, it is easy to measure the angle of narrow workpieces, which angle gauges can't measure, on the machine tools.

point finder makes it easy to measure angle of a workpiece.

When you use Centering Gauge Swing Type for a machinining center made by Okuma Corp., let us know its model.

As a standard-sized stylus, ST-6×100N is equipped with Centering Gauge Swing Type.
It is possible to exchange the size of stylus. For details, refer to 【Nonmagnetic Stylus】

Using Centering Gauge Swying Type on a machining center with a ceramic bearing, it blocks electricity and a workpiece can't be measured. 'Magnet cable M-500' is a MUST! Length: 50cm It's easy to use: put a magnet on the housing(front cover) of CG Swing Type and the other one on a workpiece.
