OperationAll Rotary Indexing Tables and A-Axes are supplied with opera-ting and mounting manuals. Interface information is also inclu-ded. Observe operation instructions of machine manufacturer,especially when Rotary Indexing Tables and A-Axes are connec-ted with machine control systems and are controlled by them.Correct operation cannot be ensured and danger to personneland machine cannot be excluded unless these operating instruc-tions or information given in this catalogue are observed.

Service and MaintenanceSince Rotary Indexing Tables and A-Axes are subject to chemicaland physical influences, maintenance and service has to beperformed with special care.EDM current flow requires a good conductive connection (con-tact) to machine table. The conductivity of water and chloridesnormally contained in water can influence the rust-resistant pro-perties of the axis. Residues (varnishes, eroded particles etc.)from the electrical discharge process should be removed on adaily basis. Contact your local HIRSCHMANN dealer for recom-mended products to use.

Technical ModificationsAll products shown in this catalogue are subject to ongoingimprovements and developments; we reserve the right for tech-nical modifications without notice.

Quality according to DIN EN ISO 9001:2000All HIRSCHMANN products are produced using state of the artproduction methods. They are subject to quality assurance mea-sures as per DIN EN ISO 9001:2000 both during production andin the assembly stage. All tables and axes are fully tested for allfunctions in a submerged environment.

WarrantyWe provide a 12 month warranty for all Rotary Indexing Tablesand A-Axes, starting from the invoice date, and assumingcorrect use and maintenance as specified.The warranty is restricted to replacement or repair, free of charge,of any defective parts. Claims arising from improper use or hand-ling shall not be considered. Warranty claims must be submittedin writing and without delay.

Introduction Many erosion tasks cannot be solved efficiently withoutusing a Rotary Indexing Table or an A-Axis, as for examplewire cutting of carbide tipped tools and turbine rings. Over150 HIRSCHMANN axes are used in the orthopaedicindustry worldwide for the manufacture of saw guides andreplacement body parts. HIRSCHMANN Rotary IndexingTables and A-Axes are manufactured with faceplates with

Characteristics

• Direct measuring system (closed loop)

• Speed range up to 30 rpm

• Faceplate diameters from 80 to 800 mm

• Machine tapers BT, SK, CAT and HSK

• For horizontal, vertical and tilt via sine use

• All surfaces and functional parts are stainless steel

• Less maintenance required

• Completely sealed (IP68) for use on Wire or Sinking EDM

• No air purge required

a diameter range from 80 to 800 mm and/or machinetapers mountings SK50 or HSK63.

Innovative HIRSCHMANN Rotary Indexing Tables and A-Axes increase productivity of EDM and improve the qua-lity of their products.

AccuracyHIRSCHMANN Rotary Indexing Tables and A-Axes are ma-nufactured to high precision standards and are subject torigid quality controls. Indexing and positioning accuracyare proportionally dependant on the quality of the measu-ring system and a drive system that is free from backlash.

HIRSCHMANN Rotary Indexing Tables and A-Axes arealways provided with a direct measuring system and anOTT worm pinion free of backlash or Harmonic Drivegears. These are conditions for highest accuracy and highprecision positioning.

Positioning accuracy is measured every 15 degrees (for-ward and back). The results are furnished in a test certifi-cate which is part of the documentation enclosed witheach Rotary Indexing Table and A-Axis.

Control SystemHIRSCHMANN Rotary Indexing Tables and A-Axes can beintegrated to machine control as an additional axis by theOEM allowing the possibility to “Turn & Burn”. For easyand quick integration the Tables and A-Axes can be provi-ded with AC or DC drives and measuring systems of thevarious manufacturers that are compatible to their controlsystems.

When integration to the machine control is not possible,the HIRSCHMANN Control System H1625 can be used. Itcan be connected to the machine control via a 24v signalfor automatic indexing only. In this case “Turn & Burn” isnot possible.

Rotary Indexing Tables and A-Axes arecompatible to EDM following manufacturers:AGIE, BES, CHARMILLES, ELECTRONICA, EXERON,FANUC, MAKINO, MITSUBISHI, OPS-INGERSOLL, SODICKand others.

Characteristics:

• Alternative to hard turning or precision grinding ofdynamically balanced parts

• Spark erosion turning with highest surface quality

• Economic production of parts with minimal structures,stainless steel microelectrodes, hard alloys, nonfer-rous metals and conductive ceramics

H80R.MAC – High Speed Rotating SpindleThe advancement in regions of micro-mechanic requiresnew ideas in production strategy.

Dynamically balanced parts with minimal diameters, diffi-cult or impossible to manufacture on conventional lathesand grinding machines, can now be manufactured on astandard Wire EDM equipped with this proven high speedspindle. High surface quality and accuracy by erosion tur-ning or grinding is achieved on small to larger dynamicallybalanced work pieces.
