Internally, the axial cylindrical roller bearings are play-free and pretensioned. The incremental shaft encoder is located directly on the rotary axis and the break is electromagnetic. The worm gear, DC gear motor, tacho-generator and all components are sealed in a stainless cast housing against fluids.

Cables and connections are protected by protective hoses or seals made of a fluorolastomer rubber suitable for continuous use in dielectric.

The stainless hardened and ground workpiece face plate is provided with M 6 and M 8 tapped holes and dirt collector grooves. The central hole has a centering seat with 30H 7 mm (1.181 ") diameter and a depth of 5 mm (0.19").

The H1625 is easily programmed via the use of "G" & "M" codes. Macro or branching capabilities are also standard to help eliminate long programs. Controls are available in German, English, French, Italian or Spanish. (other languages on by request).

The program memory is battery- buffered. The program remains in the event of power failure.

The angle or indexing steps to be programmed can be entered as absolute or incremental dimensions, and do not have to be of identical size, e.g. 1st step 15', 2nd step 27.50, etc. Inputs and outputs are provided for the connection to the EDM.
