Product catalog summary

Introduction
The document introduces the STUDER WireDress® technology, an advanced dressing technology for metal-bonded grinding wheels used in grinding ceramics, carbide, and hardened steel. This technology is integrated into STUDER S22 and S41 cylindrical grinding machines.

Integrated Dressing Technology
STUDER WireDress® allows for the dressing, profiling, and sharpening of diamond and CBN grinding wheels with electro-conductive bonds using wire EDM directly in the grinding machine. This process enhances precision and cost-effectiveness by enabling the use of sintered metal bonds, which were previously limited due to dressing challenges.

Performance Features

Increased grinding performance by at least 30% compared to ceramic bonds.
Maximum grain exposure and cutting ability.
Longer dressing intervals and higher productivity.
Easy operation with full integration into StuderWIN machine control.
Low dressing tool costs and regular grinding oil usage.
Capability to dress at wheel speeds of 120 m/s (23,620 sfpm).
No wear on the dressing tool and no deflection of thin internal grinding arbors.
High profile precision in the micron range.

Dressing Process
The dressing process is based on wire electrical discharge machining, which selectively removes the grinding wheel bond without affecting the abrasive grain. This contact-free process requires a dielectric, such as grinding oil, and allows for increased productivity and precision.

Applications and Benefits
STUDER WireDress® technology is particularly beneficial for internal grinding applications, enabling the production of complex profiles with high precision and stability. It supports the combination of up to four grinding tools in one machine configuration without retooling.

Technical Specifications

Applicable for grinding wheels with steel bodies and electro-conductive bonds.
External grinding diameter ranges from 400 to 500 mm (16" to 20").
Usable center distance up to 720 mm (28.3") for S22 and up to 1600 mm (63") for S41.
Requires an additional electrical enclosure with specific dimensions for installation.

Conclusion
The STUDER WireDress® system represents a significant advancement in grinding technology, offering enhanced precision, productivity, and versatility for various industrial applications.

STUDER WireDress® COMPONENTS Grinding wheels with extremely hard abrasives such as diamond or CBN are used for grinding ceramics, carbide, and hardened steel. In previous grinding processes, such grinding wheels very often had a synthetic resin or ceramic bond. One way to increase precision and cost-effectiveness in these grinding applications is to use grinding wheels with a sintered metal bond. However, their use has been limited so far, as metal bonds can only be dressed to a very limited extent and have only average cutting performance. With the innovative STUDER WireDress® dressing technology,...

Wire erosion selectively removes the grinding wheel bond – the properties of the abrasive grain remain unaffected. Due to the nature of the process, a dielectric, i.e., a grinding oil (no water-based emulsions), is required. There is no mechanical contact between the wire as the dressing tool, the grain, or the...
