Z軸ゼロプリセッターツール50±0.005mm CNC用の光電セット
Lights in the same spot, tolerance was good out of the box and easy to see the light. The middle section is plastic so avoiding any petroleum products on it is recommended. Converting to inch with a .8mm (.0315") metal shim, but magnets may not hold (z ok) with a shim in place, it uses the button and bottom surface for conduction. There maybe enough range on the adjustment to calibrate for inch without the shim (untested).
very good
works fine and accurate
Great value piece of tooling. I would recommend this item.
good product
