RECUTTING SERVICE

THE TECHNOLOGY OF WIRE DRAWING

… goes back to a 4000-year-old culture. Wire drawing has been practiced in Germany for around 700 years. While it used to take a great deal of physical effort to produce wires, today modern wire drawing machines do the work. Using drawing dies allows the highly accurate professional production of wires of all sizes.

RECUTTING SERVICE & MAINTENANCE

DIAMOND POWDER

For polishing diamond surfaces, synthetic and Natural diamond powder must have a good grip and close tolerances to ensure efficient processing of drawing dies. The available grit sizes are constantly tested in our own production. This ensures consistent quality with a certified scatter diagram.

POLISHING WIRE

We supply polishing wire in various materials and diameters, even in very small quantities.

DRAWING DIE CARTRIDGES

For safe and orderly storage and
transport of the drawing dies, we offer you our self-designed drawing die cartridges.

  • impact-resistant, glass-fibre reinforced plastic (PP)
  • Holds up to 36 drawing dies per cartridge
  • Transparent lid for dust-free storage – Stackable

WIRE DIE MANAGEMENT SOFTWARE

Well sorted. Fast access. Everything at a glance! For the organisation of the drawing dies, we offer our self-devellopped
software. Special features are:

  • Network capability
  • Multi-user capability
  • Database portability
  • Possibility of data backup via network
  • Privacy by password protection
  • Runs on Microsoft Windows 98® to Mircosoft Windows 11®
  • Ability of connecting different measuring systems

THE COMPANY

We are Germany’s market leader in poishingdrawing dies. As a traditional company, we supply customers in the wire drawing industry on all continents.


Company founder Hermann Friedrich (+ 1993), a master of his trade, worked for many years in a wire drawing department and as head of the drawing die polishing shop in a large wire factory. He quickly recognized the potential of an outsourced drawing die polishing shop and founded his own company in 1971, the Hermann Friedrich Ziehstein-Poliererei in Burkhardsrieth.
The company quickly grew into a competent and reliable supplier to the wire industry and is characterized by good quality management, high levels of employee qualification and excellent customer service.
Today the Bavarian company works in the second generation as a drawing die polisher and manufacturer of drawing dies worldwide. Since1996,our company has been certified according to DIN EN ISO 9001.

A successful company needs reliable employees! Today, the Hermann Friedrich Ziehstein Ziehstein-Poliererei employs around 30 people. We are particularly proud of our team, which has been loyal to us for many years! After all, loyalty and faithfulness to the company as well as well-founded professional knowledge are important attributes that make major development steps possible.

Each work process is checked manually several times. From incoming inspection to intermediate inspections to final acceptance, our products pass through many experienced hands and must be subjected to the critical looks of trained eyes of our employees stand up. Only then are we satisfied with our wire dies.

Our employees are success-oriented. They have many years of experience in handling drawing dies and know where to start. Our employees are characterized by personal responsibility and independent action. This enables us to achieve optimal results and meet delivery times.

NATURAL DIAMOND

Natural diamond is the epitome of hardness, brilliance and shiny surfaces. Our strict test criteria for selecting the rough stones guarantee a very high surface quality when drawing the wire, a long service life and the roundness of the bore. Stable sintering and application-related bore geometry ensure the highest demands in your production. Our diameter range for natural diamond drawing dies ranges from 0.02 mm to 3.00 mm.

TUNGSTEN CARBIDE

Our TC-drawing dies are characterized by tested and highly compressed hard metal qualities. Special high-gloss polish, tolerance accuracy and customer-specific bore geometry ensure stable manufacturing processes. Diamond-coated carbide drawing dies are now also available for wire drawing and stranding or compression. With a good coating thickness, these show very good service lives and wire surfaces and are used in special areas of application.

MONO

Under extremely high pressure, it is possible to produce synthetic diamonds with a monocrystalline structure. Diese Diamantkristalle zeigen absolute Reinheit, definierte <111> Orientierung und standardisierte Kristallgrößen. Monodies have an equally high-quality application for drawing dies as natural diamonds and are available in bore sizes ranging from 0.05 mm to 1.00 mm.

teaser-pkd

PCD

Polycrystalline diamond drawing dies have been used continuously in wire drawing for a long time. They are characterized by a long service life and guarantee efficient production processes. The synthetic process makes it possible to produce different surface qualities with different grain sizes. This means that large PCD pills are also available for bore areas of up to 30 mm. With standardized pill sizes, there are defined options for further processing and repolishing.

RECUTTING SERVICE AND MAINTENANCE

Professional Production – Customized Service – Certified Documentation!

The Hermann Friedrich Ziehstein-Poliererei specializes in the repair, maintenance and manufacture of all drawing dies for various areas of application.
The repair and maintenance of both individual drawing dies and entire sets of drawing dies for large systems requires conscientious inspection of wear, measurement, sorting and subsequent processing of the bore geometry.

State-of-the-art production facilities, measuring systems, cleaning systems and management software guarantee a customer-specific redesign of the drawing die geometry. In the event of heavy wear, new geometries are drilled into the drawing die using laser or eroding machines. Ultrasonic processing ensures the best polishing quality, with wire polishing machines very narrow bore tolerances can be incorporated.

The best diamond qualities are selected and used for new drawing dies, our automatic sintering technology ensures an evenly hard setting for the diamond.
Entire drawing die sets can be manufactured with wire extensions on request. The quality control of the polishing quality is carried out optically with high-resolution microscopes and requires enormous concentration. All diameters are checked with our measuring systems and documented in a reproducible manner. Special inscription lasers, which can also engrave a data matrix code, ensure clear assignment and quick access in the drawing die management.
