FEATURES
|
DIFFERENCIAL THREADS MECHANISM
One full turn of dial
Cartridge is moved by pitch difference.
|
|
|
| Adjustable in φ0.002mm increments without vernier. |
 |
| Easy adjustment is realized by the 5-times magnified graduations. |
 |
A traditional type dial is usually graduated in φ0.01mm, since it is difficult to make finer thread.
Finecut units are applicable to combination boring bars, too. |
