Point Finder is a high precision 3D touch sensor (probe) which is enable to do any kind of measurements, such as reference position, inside / outside diameter, centering, angle, groove width, and height.
All model has nonmagnetic stylus, and its repeatability is assured of ±0.5μm with the standard length stylus.
There are 5 models as PTN, PTC, WP, SPi, WPi.

Repeatedly even with a 80mm stylus length accuracy ± 1μm guarantee (Patent No. 5133884)
25 fiscal year, Chubu Regional Development Award [Invention Award] award

Specifications of the Point Finder series

Use model 'PTN' and 'PTC' when a workpiece is metal or nonferrous metal.
'SPi' is used for measuring plastic, wood and some other materials which block electricity.
For small high-speed mashining center, 'Type 06' is available.

*As a standard-sized stylus, ST-3×23.5NM is equipped with a small point finder (PTN-06N, SPi-06),
 ST-4×40NM with a point finder, and ST-6×29NM with a point finder-i.
 It is possible to exchange the size of stylus. For details, refer to 【Nonmagnetic Stylus】.

*In place of alkaline batteries [LR1AG], manganese cells can be used.
**As a standard-sized stylus, ST-4×40NM is equipped with point finder,
  ST-6×29NM with point finder-i.
  It is possible to exchange the size of stylus. For details, refer to 【Nonmagnetic Stylus】.

Using the Point Finder [External Contact Type] on a machining center with a ceramic bearing, it blocks electricity and 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 a point finder and the other on workpiece.

A magnet cable is included with a small-size point finder, PTN-06N.
In case you buy other Point Finder [External] series, make sure the specification of the machine tools you use.
