Hydraulic Chucks / Electrode Shanks
Electrodes up to 50 x 50 mm (1.968" x 1.968") are machined, used and stocked at the extremely reasonable electrode shanks. Fastening by soldering, glueing screwing etc. Shanks with special holders are used for very small electrodes.
The electrode shanks are fixed in hydraulic chucks with highest repetitive accuracy.
For the machining of the electrodes the shanks are fixed in the hydraulic chuck and in the hydraulic clamping block.
H 5.50.20 Hydraulic Chuck
For precise mounting and angular fixing of electrode shanks by means of a hardened pin positioned across the center hole of the chuck and aligned with the centering Vee blocks on the tool plane.

Hardened and chemically nickel-plated. With reference point, internal flushing and external flushing connection.

Changing accuracy of the electrode shank, measured 50 mm (1.96") below the

clamping chuck < 0.005 mm (0.0002")
Repetitive accuracy <0.002 mm (0.00008")
The dimension from the centering Vee block to the fixing
pin is identical from unit to unit (< 0.01 mm/0.0004").
Weight: 2 kg (4.41 lbs)
H 5.51.20 Hydraulic Chuck, horizontal
Same design as for H 5.50.20. Provided with four fixing pins, each offset by 90°, so that the electrode shanks can be indexed 4 x 90°.

The dimension from the centering Vee block to the shank hole is identical from unit to unit (± 0.01 mm/ 0.0004").

Weight: 2.5 kg (3.51 lbs).

 

H 83.20 Hydraulic Clamping Block
For mounting and precise angular fixing of the electrode shanks, with four fixing pins each offset by 90°, so that the electrode shanks can be indexed 4 x 90°'. With five precision- ground contact surfaces.

The dimension from the center to the contact surfaces is engraved on the face side and is used for alignment of the hydraulic clamping block.

The hydraulic clamping block is used for electrode manufacture on milling, drilling and grinding machines and is a standard equipment.

Suitable for use in dielectric.

H 50.30 Electrode Shank
Working length 24 mm (0.945"), with unhardened flange. Ø 49 mm (1.929"). Permissible electrode weight 10 kg (22.05 lbs).
H 50 K Single-package System
For attachment of small or lightweight electrodes to the electrode shanks. SICOMET 85 is suitable because of its short setting time (90-150 sec.) and high tensile shear strength (~ 27 N/mm2).
The surfaces to be glued must be absolutely free of grease. Use at room temperature.
Storage at +20" C approx. 6 months, at -200 C approx. 12 months.
Delivery: Work bottle - contents 50 gr.
Ensure contact between electrode and electrode holder.
H 50.35 Flat Electrode Holder
For mounting small and flat electrodes, as for example small sheet-metal electrodes or rod electrodes.

Clamping range up to 5 x 12 mm (0.197" x 0.472").

H 50.40 Collet Holder
Clamping range 0.5-10 mm (0.0197"-0.3937"). Built-in and easily replaceable sealing disc with 3.7 mm (1.457") hole. Five sealing discs without hole included in the scope of delivery. Supplied in a wooden box.

H 50.41 Collet ER/ESX 16
Clamping range 0.5-10 mm (0.0197"-0.3937"), infinitely variable, in 1 mm (0.03937") increments.
Radial runout 0.01 mm (0.0004"), above 6 mm (0.237") 0.02 mm (0.0008").

H 50.42 Replacement Sealing Discs
(5 discs without hole)

H 50.5 Precision Tubing Chuck
For mounting small tubular electrodes. Clamping range 0-3 mm (0-0.118").
Radial runout < 0.05 mm (0.002").
Internal flushing. Five easily replaceable sealing sleeves are included in the scope of delivery. Delivery in a wooden box.

H 50.51 Replacement Sealing Discs
(5 discs without hole)
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 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.
