  • Diamond abrasive quickly removes material from the hardest substrates
  • Consistent cut minimizes sub-surface damage
  • Waterproof backing reduces slurry clean-up and toxic waste disposal issues
  • Cleaner operation reduces machine wear
  • Cleaner operation reduces machine wear
  • Use on your existing flat grinding and finishing equipment
  • Adhesive backing for easy attachment

The 3M™ Trizact™ Industrial Diamond QRS HX Film Disc 673LA is designed for speed, consistency and control in flat finishing, grinding and lapping applications on technical ceramics, glass and exotic metals. The diamond-filled hexagonal structures are bonded to waterproof backing with a layer of polycarbonate for support, enabling use with coolants. Adhesive attachment enables speedy disc changes.

Flat, Fast and Fine
Ideal for finishing hard-to-grind materials, 3M™ Trizact™ Industrial Diamond HX Film Sheet 673LA may reduce total cycle time when used for intermediate grind and pre-polishing technical ceramics, glass and exotic metals.

To achieve precise surface parameters, the size, shape and surface of the abrasive is key to success. Consistent shape and size of abrasive mineral enables optimum material removal rates and constant uniform contact with the surface of the workpiece. Irregular size and shape can scratch or gouge.

Trizact abrasive minerals are engineered to be precisely-shaped, three-dimensional structures uniformly distributed over the surface of the backing. As these structures wear, fresh, sharp diamond abrasive is continually exposed to the workpiece — resulting in faster, more consistent cutting throughout the life of the material.

Reduce Slurry Clean-up, Use Existing Equipment
These abrasives are 3M's time- and money-saving alternative to messy slurries and expensive fixed abrasive systems such as pellet laps. Designed to work with aqueous coolants, they reduce cleanup and toxic waste disposal issues associated with abrasive slurries. Use a 90/10 mixture of water with any water-based (aqueous) coolant. Any glycol-containing solution or plain water is satisfactory. They can be used on your existing flat grinding and finishing equipment.

Finishing Exotic Metals More Efficiently
3M™ Trizact Diamond HX Film Sheet 673LA has demonstrated outstanding performance on a wide range of demanding materials including: Spinel • Sapphire • Alumina • Zirconia • Ferrites • Tungsten carbide • Ferroelectric ceramics • Silicon nitride • Silicon carbide • Beryllium • Molybdenum • Aluminum • Glass • Glass ceramics • Various optical substrates • Silicon wafer reclamation • Others

Recommended Applications
Typical Flat Part Processing Sequence

  • Step 1: Grind to Flat (Blanchard Grinding) with 3M Superabrasive wheels
  • Step 2: Refine Finish with 3M Trizact Diamond 673FA/LA. Finishes as fine as sub 1 μin Ra are possible. Use of 673FA/LA abrasives in Step 2 may reduce final polishing time up to 50 percent.
  • Step 3: Polish (optional). Final polish is typically performed using slurry on a felt pad. 3M™ Trizact™ Film 568XA has shown outstanding results on glass substrates.

3M Smooth
3M™ Trizact™ abrasives were developed specifically for finishing more difficult processing materials such as titanium, cobalt, stainless steel, as well as for all exotic alloys in the aerospace, aviation and medical industries, where precise geometries and critical tolerances mean everything.

From medical implants to surgical tools to automotive transmission components, 3M™ Trizact™ technology is only one of the high performance solutions we are driven to develop to improve work, life and our world.
