Designed for grinding steel, stainless steel and other materials in nuclear plants, oil and gas industries and applications where spark reduction is an important feature.
Eco Brazing (EB) diamond grinding discs from CS Unitec reduce sparking by up to 1/100 of that produced by resinoid wheels, making EB diamond a better choice than resinoid for use in some hazardous environments.
- Diamond grit protrudes higher off the EB diamond disc than traditional diamond wheels, providing greater durability, longer service life and cutting
- High-tensile steel backing disc reduces plate thickness for a lightweight wheel that allows for high-rotation grinding
- High yield strength makes the steel backing disc elastic, helping to ensure that operators do not grind the material by over-removal
- Reduced sparking increases the visibility of the workpiece
- The EB diamond wheel wears approximately 1% as much as a resinoid wheel, therefore significantly reducing the amount of abrasive dust emitted
- Ideal for grinding steel and stainless steel, as well as natural stone, granite, marble, fiberglass and other materials
EB diamond grinding discs reduce sparking up to 1/100 of that produced by resinoid grinding wheels (inset left).
