P Compatible with the Fixturing Systems 2000 and 4000.

OperationMost tools are supplied together with an operating ma-nual. Correct operation cannot be ensured and dangerto personnel and machine cannot be excluded unlessthese operating instructions or information given in thiscatalogue are observed.

PrecisionThe individual tool planes incorporate hardened and ar-tificially aged precision ground centering Vee blocks andseparate Z-supports. This assures position centering ofeach tool. When the reference points are in alignment, arepetitive accuracy (consistency) of l 0.002 mm(0.00008”) is achieved, measured 100 mm (3.937”)below the tool plane.When indexing an electrode holder in the Vee block by4 x 90°, the axis position will be l 0.004 mm. It must beremembered here that the axis displacement of the el-ectrode holder, for example of a collet holder, and of thecollet will add to the axis position variation.

Cleaning and lubricationThe tools should be cleaned with a clean cloth, on noaccount with compressed air. Only oil must be used forlubrication.

Technical modificationsAs all products shown in this catalogue are subject tocontinuous further developments, we reserve the rightfor technical modifications.

Quality according to DIN EN ISO 9001All HIRSCHMANN GMBH products are produced usingthe latest production methods, and are subject to quali-ty assurance measures as per DIN EN ISO 9001 bothduring production and in the product stage.

WarrantyWe provide a 12-months warranty for all fixturing systemparts produced by us, starting from the invoice date,and assuming correct use and maintenance as speci-fied.The warranty is restricted to replacement or repair, freeof charge, of any defective parts. Claims going beyondthat shall not be considered.Warranty claims shall be submitted without delay and inwriting.

The H 200 Rotary Dividing Table is used for mountingand precise positioning of those workpieces of whichthe penetrations or depressions to be machined havethe same angle to a common center point and are loca-ted on one or more pitch circles or on the circumferen-ce of rotationally symmetrical parts.These rotary dividing tables have been developed spe-cially for use on EDMs. All function components, suchas those for bearings, indexing and clamping are sealedagainst dust and fluids.The hardened workpiece mounting plate is ground bothon its face and on its circumference and provided with12 M 6 or M 8 tapped holes for workpiece fastening andwith dirt collector grooves.

Design: Supported on three roller bearings, 360° index-ing, fixed scale ring – adjustable vernier, fine setting, 24indexes (15°), positive, non-slip clamping, completelysealed for continuous use in dielectric.The central hole has a centering seat with 30H7 mm(1.181") diameter and below that, below an unhardenedand replaceable cover, a flushing tank for central pres-sure / suction flushing. The flushing connection is loca-ted on the circumference of the mounting plate.Positioning: The rotary dividing table is positioned inrelation to the quill of the EDM by circling using a cen-tering spindle as H 50.7 or H 5.50.6, using the table cen-tering device or the ground outer diameter of the work-piece mounting plate.

NC-controlled Rotary Table in stainless and sealed designfor horizontal and vertical use in dielectric on the EDM

The NC-controlled rotary dividing tables are used for au-tomatic positioning of those workpieces of which thepenetrations or depressions to be machined have thesame angle to a common center point and are locatedon one or more pitch circles or on the circumference ofrotationally symmetrical parts.All function components, such as the axial cylindricalroller bearings with play-free pretensioning, the incre-mental shaft encoder located directly on the rotary axis,the electromagnetic clamp, the worm gear and the DCgear motor with tacho-generator, are in a special casthousing sealed against fluids. Cables and connectionsare protected by protective hoses or seals of resistantfluoroelastomer rubber suitable for continuous use indielectric.The hardened and ground workpiece mounting plate isprovided with M 6 or M 8 tapped holes and dirt collec-tor grooves.The central hole has a centering seat with 30H7 mm(1.181”) diameter and a depth of 5 mm (0.19”).

H 1625 CNC Control The CNC 1625 is a freely programmable straight-linecontrol. The operator is guided in plain language (Ger-man, English, French and Italian) in VDU dialogue.(Other languages on demand).The program memory is battery-buffered. The programremains in the event of power failure.The angle or indexing steps to be programmed can beentered as absolute or incremental dimensions, and donot have to be of identical size, e.g. 1st step 15°, 2ndstep 27.5°, etc. Inputs and outputs are provided forconnection to the EDM. The CNC programs can besaved and loaded externally via the V24 (RS232) inter-face.

NC-controlled erodible C-axesWith an EDM under NC-control and having a HIRSCH-MANN C-axis, it is possible to erode automatically elec-trodes of any shape which are identical and on the samepitch circle, as well as threads, steep-angle gears, hob-bing on the exterior of a workpiece, relief cuts etc.

P Automatic electrode change possibleP Mounting of very small and large electrodes using all

electrode holders of the Fixturing System 5000P Mounting of large and very heavy electrodes on the

grooved plate, without removal of the C-axisP Backlash free drive, permitting electrical discharge

machiningP High indexing accuracy l ± 10)P High repetitive accuracy l ± 5)

The pneumatic tool clamper for mounting the electrodeholder, is located in the center of the clamping plate. Thetool clamper interlocks in case of power or pressure fai-lure. The clamping plate is used for mounting large elec-trodes in manual mode.All function components, such as the pretensioned pre-cision bearings, the incremental shaft encoder locatedon the rotary axis, the non-slip disc clamp, etc. are in anenclosed, sturdy housing. The tool clamper and theclamping plate are mounted insulated from the housingand the function components.The electrode flushing takes place through the centerhole of the C axis.The integrated C-axis is supplied with or without driveunit, as requested.If required, the C-axes are also supplied without clamp-ing plate.

Electrode and Workpiece MeasurementThe measuring plate represents the most convenientmethod of measuring electrodes.Reference positions, zero points and possible offset ofone or more electrodes in relation to one another can bedetermined simply on the measuring plate using a suita-ble height measuring device with digital display.For this purpose, the electrode holder is placed on thePallet Clamper H 8.811 (see illustration). To assure therunout or angles, the Machining Dividing Head H 8.80 isused.

3D Measuring CenterFor the simple electrode and workpiece measurementand for determining the position of the coordinates elec-trode/workpiece in relation to the centering Vee block ofthe holder or the pallet. The usage of a measuring ma-chine directly at the working place offers the followingadvantages:P High measuring capacityP Economical and preciseP Very user-friendlyP For all purposesP On-line transfer of the measurement data or correc-

tion values to the EDM

Workpiece FixturingFor mounting the HIRSCHMANN electrode holders orworkpiece pallets a pneumatic workpiece clamper ispositioned on the measuring plate.
