Point Finder Series [Nissin Sangyo]

Features of the Point Finder Series　

・High precision 3D touch sensor (probe) 'Point Finder series' is enable to do any kind of measurements such as reference position, inside/outside diameters, centering, angle, groove width, and height.
For the ultrahigh-precision 3D touch sensor →　【Centering Gauge Swing Type】

・Safety design enables the stylus swing toward X, Y and Z-axes directions and prevents the Point Finder itself from breakage.

・Four LEDs light up when the stylus touches to a workpiece.

・As for PTC (Point finder with a buzzer), three LEDs light up and the buzzer let you know when the stylus touches to a workpiece.

・With nonmagnetic stylus, magnetic force doesn't affect to the measuring.
→　Check the details of 【Nonmagnetic Stylus】

・Waterproof IP 67 (IEC standard) will not enter water even if it is immersed in 1 m of deep for 30 minutes.
(We use fluororubber for our products, but some cutting fluid contain surfactant dissolves fluororubber, and our company prohibits its use.)

*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.
　　　For details, refer to 【Nonmagnetic Stylus】
*3：When using the internal contact method with a stylus of 30 mm or more attached, repeatability can not be guaranteed.

How to Measure　

　Point Finder makes it possible to do any kind of measurements such as reference position, inside/outside diameters, centering, angle, groove width, and height. Those measurements are very important before metal working.

　With a point finder, it is easy to measure the angle of narrow workpieces, which angle gauges can't measure, on the machine tools.

Point Finder series are available to measure any position and angle.

*tan^-1tan-1　is called undertangent．
Please calculate it with a calculator or use a smartphone calculation application.
