Holding a profile to micrometre accuracy calls for a different dressing tool than grinding under heavy loads. Norton uses reverse-plated rolls for the first task and wear-resistant sintered rolls for the second.

Norton’s dressing tools are designed for high precision and productivity. Accurately dressed grinding wheels allow operators to achieve higher material removal rates, maintain profile accuracy and grind more parts between dressing operations. This can often cut downtime and overall costs considerably. Norton combines three dressing technologies with advanced manufacturing methods and applications expertise to tailor its tools to specific process requirements.

As a leading manufacturer of diamond dressers and dressing tools, Norton has extensive expertise in controlling the parameters that govern the dressing process. Precise control improves accuracy and process reliability while maintaining consistent product quality and dependable performance. Norton offers three dressing technologies, each suited to specific process requirements.

Reverse-plated dressing rolls

Reverse-plated dressing rolls are particularly well suited to applications that demand the highest profile accuracy. Nickel electroplating, uniform diamond distribution and micrometre-level precision allow the rolls to dress even the most complex profiles accurately. This helps users maintain consistent workpiece quality, keep processes stable and reduce scrap rates. Application-specific designs and the option to regrind the rolls further extend tool life and keep overall costs low.

Dressing rolls with an infiltrated sintered bond

For applications involving high material removal rates and heavy mechanical loads, Norton offers dressing rolls with an infiltrated sintered bond. The tungsten-based bond, combined with natural diamonds, synthetic chemical vapour deposition (CVD) diamonds or a combination of the two, provides high wear resistance and long tool life. Dressing operations therefore remain reliable and economical even under demanding conditions.

The rolls can be reground and tailored to individual applications. Users benefit from fewer tool changes, greater process efficiency and consistent grinding results over time. Precision manufacturing and tight tolerances help maintain process reliability even in demanding applications.

CNC dressers

Norton’s CNC dressers are designed for applications that require operators to reproduce complex profiles with a high degree of precision. Selected natural diamonds and CVD diamond rods, combined with a wear-resistant bond, deliver high profile accuracy, long tool life and consistent results.

Developed specifically for CNC dressing, these tools allow operators to produce even intricate profiles accurately and repeatedly. This supports stable processes, consistent product quality and economical production. Precision manufacturing, tight tolerances and application-specific designs help ensure process reliability in series production.

“Our high-performance dressing rolls are a central part of our extensive portfolio,” says Eduardo Mattei, who works in technical sales at Norton. “Our focus, however, extends well beyond the product itself. We look at the entire grinding process and help our customers optimise their systems throughout their life cycle. Our aim is to maintain the highest precision over the long term, increase productivity and reduce overall costs at the same time. To achieve this, we offer a comprehensive range of services, from precision mounting of dressing tools and data-driven product design to spindle inspection, repair and replacement.”
