Measuring Machine for Small Internal Diameter [IDM series] 

IDM is an instrument which measures the distance between one wall
to the other wall of a workpiece by the optical principles.
IDM can measure the diameter of thru-holes fromφ0.1mm to φ100mm
without master gage, and easily in the following procedure.
The prominent feature is that measurement is took between bore
walls at any height desired.
IDM optically detects a wall on one side of the work at the first,
and the display counter is set to zero in this position.
Next, the opposite wall is optically detected. this distance is not
other than moving quantity of the work which is read on the digital scale.
IDM can be applied to many other measurements such as slit widths,
outside diameters, wall perpendicularity and bore pitches, not only bore.
There is no mechanical measuring force to the work during measurement,
so that IDM can be used for soft material and thin wall works.

Precision Indexing Devices [SPID-720/A] 

This indexing device indexes by means of 720 top and bottom, fully
coupled serrations.
After each individual serration is precisely ground, they are lapped
until they make full contact.
Therefore, accurate indexing is possible because each individual top
and bottom serration coupled accurately and uniformly.
Moreover, deterioration of precision indexing is difficult, and precision
is maintained for a long time.
Furthermore, SPID-720 is manual, and SPID-720A is motor-operated.

Precision Rotary Table [SPRT-200/V200] 

Super Precision Rotary Table SPRT series is a continuous rotary table
developed mainly for grinding(but cannot index).
By combined use of the tool grinding machine and the grinding center,
it is possible to finish the cylinder, end face, and hole etc. with
high precision.
Moreover, it can be used as an inspection tool for testing run out.
