定位片是夹持电极的最经济的基础件。它可直接装于电极毛胚上。这样，电极的夹具也与ITS匹配。安装孔的布孔只需简单地用钻孔模板或用在NC编程的方法，直接在胚料上钻孔。

Setting up
Preparations - Machine the surface to which centering plate is to be fitted. Note that turning provides a more even surface than milling.
- Drill holes according to the pattern shown below. For this purpose, we supply a drill template ER-010710 (option) as an option.
The hole pattern can also be produced with the help of an NC machine.
Note: The ø 9 mm and ø10 mm holes are to accommodate the prismatic spigots of the rapid-action chuck and must therefore be drilled in any case.
The 4H7 holes are only necessary if the centering plate must be aligned in relation to a given reference surface.
Assembly- Put base plate (A) on the hole pattern of the blank.
Put centering plate (B) on top in the congruent position.
Note: The positioning mark (C) must remain visible after the centering plate has been put on. If a reference surface has been given, the reference marks (D) must refer to it.
- If necessary, align centering plate with ø 4 pins.
- Turn the 4 support feet into the M5 threads and tighten to 8 Nm.
Check- Put the assembled blank onto an alignment plate. If it wobbles in any way, the following corrections are possible:
a) Lap the support feet in the assemblid state. This provides the best results. Try to achieve an evenness of 0.001 mm (F). The distance between support feet and mounting surface must be kept within the tolerance 11.2 +0.01/-0.05 (G).
Note: Measuring points on the mounting surface are possible in the holes (H) or beside the plates (J), depending on the version.
b) In the case of small errors, whet with an oil stone.
