H 25 Rotating Spindle
For operation with tubular electrodes from 0.5-10 mm (0.0197"-0.3937").

High stock removal rate and precision, more stable machining regardless of the machining depth.

Sealing between flushing and electrode is assured by a built-in, easily replaceable rubber sealing disc with 3.7 mm (1.457") hole. Five sealing discs are included in the scope of delivery.

The spindle is driven by a DO motor. The working current is supplied via a sliding contact. Internal flushing.

Radial runout, measured in the collet mounting 0.02 mm
(0.0008"), plus collet error.
Speed range, infinitely variable 20-1500 rpm
Perm. electrode weight 0.5 kg (1.1 lbs)
Perm. working current 5 A
Weight 3.2 kg (7.06 lbs)
H 20.2 is used as control unit.

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. The same collet is used in the Collet Holder H 50.40.

H 50.42 Five Replacement Sealing Discs
H 25.10 Rotating Spindle
For operation with small tubular electrodes up to 3 mm (0.118"). Design similar to H 25, but equipped with chuck.
