H 5.50.6 Centering Spindle
For centering or determining the position of holes and round parts.
When used in conjunction with the Aligning Gauge H 5.50.9 the axis position of a pallet clamper mounted on the machine table can be determined.
When used under dividing heads or C-axis, ensure that the latter is not adjusted during and after the centeri'ng operation, as the runout tolerances can then become cumulative.

H 5.50.61 Feeler Lever Gauge, 0.002 mm (0.00008") 
(not included in the scope of delivery)
H 5.50.66/2 Ball-type Surface Finder
For determining the position of the workpiece. 
125 mm (4.920") long, with hardened steel ball, diameter 2 (+0.002, -0.005)mm (0.078").


H 5.50.66/5 Ball-type Surface Finder
125 mm (4.920") long, with hardened steel ball, diameter 5(+0.002, -0.005) mm (0.197").
H 5.50.7 3D Surface Finder
Ball diameter 5 mm (1.97").

For determining the position of the workpiece by contacting of edges and holes.  A 1 mm (0.03937") overrun prevention feature is incorporated for all three directions. The repetitive accuracy in X-, Y- and Z-direction is 0.002 mm (0.00008").

With NC-controlled EDMs, the finder can be used for automatically determining the workpiece position.

H 5.50.75 Centering Microscope
For optically determining the position of holes or workpiece edges.

30 x magnification.
With sight angle and transformer 110-240/3-8 V.

H 5.50.8 Test Bar
For aligning and checking the axis and radial position of the mounted tool clampers, and for concentricity and system checks.

H 5.50.9 Aligning Gauge
For aligning and checking the tool and pallet clampers in the X-N-direction, and for checking the quill/pallet clamper in the center position.

H 50.65 Ball-type Surface Finder
For determining the position of the workpiece.
50 mm (1.968") long, with centrical welded, hardened

steel ball, diameter 4 or 10(+.002, -.005 mm) (0.158" or 0.3937").

H 50.66 Ball-type Surface Finder
100 mm (3.937") long, otherwise same design as for H 50.65.

H 50.7 Centering Spindle
For centering or determining the position of holes and round parts.
When used in conjunction with the Aligning Gauge H 5.50.9 the axis position of a pallet clamper mounted on the machine table can be determined.
When used under dividing heads or C-axis, ensure that the latter is not adjusted during and after the centering operation, as the runout tolerances can then become cumulative.

H 5.50.61 Feeler Lever Gauge, 0.002 mm (0.00008")
(not included in the scope of delivery)
H 50.80 Aligning Rule
The aligning rule is used for aligning the hydraulic chuck on the EDM, for example below a dividing head or a C-axis, for repetition of an angular position.
