Innovative Grinding Technology: Wiredress – Revolutionizing the Grinding Process
The traditional grinding process has long been a time-consuming and labor-intensive task, requiring constant dressing and re-dressing of grinding wheels to maintain optimal performance. However, with the introduction of Wiredress technology, the game has changed. This innovative technology, developed by Fritz Studer AG, uses electroerosion to open up new possibilities for grinding with metal-backed grinding wheels, resulting in a 30% improvement in grinding performance and a 70% reduction in grinding wheel wear compared to ceramic adhesives and resin adhesives.
The Power of Metal-Bonded Grinding Wheels
Metal-bonded grinding wheels, with their high hardness and resistance to deformation, are particularly effective for treating difficult-to-cut materials such as hardened steel, cemented carbide, and ceramics. The ability of these wheels to unload heat generated during grinding quickly makes them an attractive solution for demanding applications.
The Limitations of Traditional Dressing and Grinding
While metal-bonded grinding wheels offer significant advantages, their limitations are also well-known. The use of silicon carbide dressing wheels, for example, can result in unsatisfactory results, while precise contours are often impossible to achieve. Furthermore, the separation of abrasive particles from the metal matrix can be challenging, leading to damage to both the wheel and the dressing wheel. Additionally, the high grinding speeds required to achieve optimal performance can lead to wear on the dressing wheel, limiting its geometric precision.
Introducing Electro-Erosion Dressing
In response to these challenges, professionals have developed alternative dressing methods, including electrochemical dressing processes (ECM) and electroerosion (EDM). These processes enable the production of high abrasive exposure heights and do not require physical contact during the cutting process. The electroerosion process, in particular, offers several advantages, including the ability to remove material without the need for a chemically active liquid to remove the metal binder.
The Electroerosion Process Explained
The electroerosion process, also known as EDM, is based on the principle of electric sparks. During the process, ultra-short electrical pulses are used to generate a spark between the electric probe and the electrolyte, resulting in the removal of material from the metal matrix. This process allows for the precise cutting of metal-bonded grinding wheels, making it an essential component of the Wiredress technology.
Introducing the Studer-Wiredress System
Fritz Studer AG has developed a new finishing machine, the Studer-Wiredress, which integrates the electroerosion dressing process into a single machine, eliminating the need to remove the grinding wheel for dressing. This innovative system offers several advantages, including increased productivity, reduced costs, and improved precision.
The Studer-Wiredress System in Action
The Studer-Wiredress system is designed to work in tandem with the industry-leading S22 machine, which is capable of performing various machining tasks, including internal and external cylindrical grinding, tool grinding, and heavy-duty grinding applications. The system is also available for internal and external cylindrical grinding on the CNC S31 and S41 machines.
