The 3M Customer Abrasive Methods (CAM) 

Center, located at 3M’s St. Paul, Minnesota, 

headquarters, was established to help 

customers identify the most cost-effective 

combination of abrasives, equipment and 

techniques for their particular applications. 

At the CAM Center, evaluations are carried 

out under controlled, repeatable conditions 

using a wide array of production scale 

grinding, polishing and finishing equipment, 

as well as in our on-site research and 

testing laboratories.

The services of the 3M CAM Center 

include applications development, 

process optimization, operator 

training and other technical 

support. Contact your local 3M 

representative for more information.

It’s like adding two new grinders – with a minimal investment 
in new equipment.

3M has partnered with equipment builders who will work 
with you to convert your existing grinder into a flexible tool, 
capable of utilizing both wheels and 3M superabrasive belts.

Now you can experience increased production, ease of use 
and consistent performance of 3M abrasive belt technology 
on your existing bonded wheel grinder – for as little as 5% of 
the cost of a new machine!

By reducing the cost of each part produced, your converted 
grinder can pay for itself in as little as six months.

 Process Recommendations  

 and Expected Results

Increasing restrictions on the use of hexavalent chrome have 

hastened the switch to thermal spray hard coats and other 

advanced materials in high performance corrosion control and 

wear-resistance applications.

Traditional grinding and finishing methods are proving less 

effective on many of these newer, hard-to-grind materials 

– slowing down production and driving up costs.

Now, 3M brings you a broad range of solutions designed to 

meet today’s tough processing challenges. From grinding-to-

dimension all the way to superfinishing, 3M has the tools you 

need to achieve stringent geometry tolerances and finish specs, 

part after part. Compared to traditional bonded wheels and 

honing stones, 3M abrasive belts are easier to use, and less 

dependent on operator skill – for more consistent, predictable 

results. And because they cut faster, and don’t require dressing, 

3M abrasive belts can help you increase production without the 

need to invest in new machines or add shifts.

Just as important, 3M offers you the technical support and 

application development resources – backed by over 100 

years of abrasives experience – to help optimize your process, 

and take full advantage of all the benefits these exciting new 

technologies have to offer.
