Gisco Premium EDM Wires

GISCO COBRA CUT FAMILY
The coated wire electrode series COBRA CUT® was developed with AGIE for EDM machines. They are suitable for a number of different machine models and for practical applications.

Gisco Cobra Cut
Soft Brass Core/Tensile Strength 70,000 psi
These zinc-coated wire electrodes were initially produced for AGIE for their first AC machines. Due to its elongation, it is particularly suitable for high tapering. It has a limited suitability for machine models with automatic water-jet threading.

Gisco Cobra Cut A
Hard Brass Core/Tensile Strength 130,000 psi
This hard, zinc-coated wire electrode is especially suitable for machines with automatic threaders. Due to its excellent straightness and precision, it guarantees very good surface qualities and allows precision cuts and fine detail with the highest reliability in automatic operations (particularly with .003", .004" and .006" diameter wires). With this wire, steep taper cuts are possible only to a limited extent, except on the following AGIE machine models for which it is specified: AC 100, 200, 300, 100D, 200D and 300D.

Gisco Cobra Cut B
Soft/Tensile Strength 65,000 psi
The special CuMg core of this electrode provides high electrical conductivity. Its rougher, oxidized surface benefits flushing conditions and is advantageous for the cutting of tall work pieces (>4"). Recommended for fast cutting of graphite and aluminum alloys. This wire is suitable for tapering to 20o, but has limited capability for skim cutting and automatic wire threading. It is specified for the following AGIE models: AC 100, 200, 300, 100D, 200D and 300D.

Gisco Cobra Cut D
½ Hard/Tensile Strength 115,000 psi
This wire electrode has been developed for EDM machines with high-power generators. It has a high thermal and electrical conductivity due to its special coating. It consists of two CuZn alloys (brass-on-brass), and is therefore suitable for speed cutting as well as for precision contour cutting. It can be used on machines with automatic threading. Tapered cuts (>7°) are possible only to a limited extent, except on the following AGIE machine models for which this wire is specified: AC 100D, 200D, and 300D.

Gisco Cobra Cut S
½ Hard/Hard Brass Core/Tensile Strength 115,000 psi
This wire electrode guarantees highest cutting rates on the latest high-power EDM machines. As an improvement of the COBRA CUT® Type D, the thicker diffusion coat provides better cutting performance. It is most suitable for use in high-volume production EDM, tool and die making, and for thick workpieces. It is suitable for automatic threading and is specified for AGIE AC Sprint machines.

Gisco Cobra Cut W
Soft/Tensile Strength 62,700 psi
This diffusion-annealed wire is designed to deliver the high productivity of Cobra® Cut D with the high elongation of BercoCut 390 wire. Suitable to taper cuts up to 45°.

GISCO TOPAS FAMILY
TOPAS® is the first gamma phase wire from Berkenhoff which can be universally used on all standard EDM machines and achieves excellent cutting rates with high precision and surface quality. Economical production processes demand ever increasing removal rates. Our new TOPAS® electrodes meet these most exacting requirements thanks to their special coating. They cut up to 50% faster than plain wires.

In comparison with "hot-dipped" wires, the TOPAS® EDM wires achieve a significantly higher cutting rate. They also offer better fine finishing characteristics compared to diffusion annealed wires. And so the major performance criteria are met without compromise: high precision at fast cutting rates with high surface quality at the workpiece.

Gisco Topas S
Soft/Tensile strength 70,000 psi
TOPAS® S is especially suited for taper cutting with reliable edge-finding.

Gisco Topas H
Hard/Tensile strength 115,000 psi
With its high tensile strength, type H is particularly suited for machines which require straightened wires for threading. A crucial advantage is the universal usability of the TOPAS® EDM wires on all conventional EDM machines with existing standard technologies. This allows considerable performance advantages without involving extra time and costs for reprogramming.

GISCO BRONCO CUT FAMILY
This coated EDM wire series BRONCO CUT® was initially developed for the special application on Charmilles Technologies EDM machines, it also meets the particular threading requirements of this manufacturer. The manufacturer of Charmilles is introducing this type series on the market with the identification "SW-....".

Gisco Bronco Cut
Soft/Tensile strength 65,000 psi
This zinc-coated copper EDM wire is designed for compatibility with the annealing and calibration devices of earlier Charmilles machines. These are Charmilles F series machines (420, 430, 431 and 453) Charmilles CH series machines (452, 552) and Andrew machines. This wire can be used on these machines for various applications; however, they are suitable for precision cutting only to a limited extent.

Gisco Bronco Cut X
Soft/Tensile 72,000 psi
This high-performance, multipurpose EDM wire with a special zinc-rich coating is suitable for precision cutting as well as high-speed cutting. Excellent automatic threading reliability except for the following Charmilles machines Robofil 100 and 1000 series. Taper cutting (>7°) only to a limited degree.

GISCO MEGACUT FAMILY
This electrode type MEGACUT® was especially developed for Japanese EDM machines.

Gisco MegaCut A
Hard/Tensile strength 130,000 psi
In small diameters (.003" - .008"), this zinc-coated precision wire is suitable for cuts with tight corner radii. It offers high cutting rates and performs well in critical applications (for example, in tungsten carbide alloys). The wire has excellent manual and automatic threading capabilities. Taper cutting (>7°) is only possible to a limited degree. This wire is in compliance with Mitsubishi EDMs. This wire is used when fine surfaces are required, it is also recommended when cutting carbides and poly-crystalline diamond.

Gisco MegaCut HS
½ Hard/Tensile strength 115,000 psi
This electrode is suited for the high-power generators of the latest machines and offers maximum cutting rates, making it ideal for high-speed productions. Type HS has a thicker coating than Type D in order to compensate for the increased consumption of the electrode during high speed cutting. Due to its straightness, the wire is especially suited for machines with automatic threading and was specifically designed for the Mitsubishi HA and U series Wire EDMs.

Gisco MegaCut W
Soft/Tensile strength 62,700 psi
This type has the highest elongation of the MEGACUT® series. The "soft" electrode allows steep tapering. The special coating can resist thermal loads arising from poor flushing conditions. Suitable for taper cuts up to 45°.

Gisco MegaCut D
½ Hard/Tensile strength 115,00 psi
Due to its special coating, this electrode is ideal for speed cutting, providing the highest performance. This wire is also recommended for tall workpieces, interrupted cuts and poor flushing conditions. For taper cutting (>7°), this wire is suitable only to a limited extent. Type D wire complies with Mitsubishi EDMs.

Gisco MegaCut T
Soft/Tensile strength 70,000 psi
This wire electrode is similar to MEGACUT® Type A but has reduced hardness, making it perfectly suitable for high tapering requirements. Because of this increased tapering capability, this wire will have limited automatic threading capability. It is a soft zinc coated brass wire for machines with round diamond guides.

Gisco MegaCut Brass
Hard/Tensile strength 130,000 psi
The MegaCut® hard brass EDM wires are subject to the same strict production standards as the other brass and coated wires. CuZn37 (Ms63) is available in a hard temper with a tensile strength of 130,000 PSI and is suitable for auto threading. MegaCut® brass is straightened specifically for use on Japanese machines. It is only available on Japanese standard spools.
