Designed with a strong polyester film backing and sharp diamond
mineral, the Diamond Microfinishing Film Roll delivers fine
finishes on hard metals like thermal spray coating, ceramics,
carbides, chilled iron and granite.
High-quality Materials for Micro-finishing
Diamond Microfinishing Film Roll securely anchors micron-graded
diamonds to a polyester film backing. Known for its strength and
resilience, the polyester film backing keeps the abrasive from
skidding or deflecting when run. This backing helps the
superabrasive belt stay taut and tough so that it can withstand
heavy-duty finishing. The belts are also color coded by grade to
help you reduce the risk of selecting the wrong grade.
Waterproof Backing
Polyester film backings are also water resistant, so the abrasive
may be run with a wet surface lubricant, which helps wash away
unwanted swarf and debris and keeps the abrasive running cool. When
used in roll form for a process like superfinishing, our roll
enables slow abrasive feed rates and requires fewer steps, because
of its durability, which in turn can reduce costs.
Tips for Achieving Desired Roughness Average
Many micro-finished products require a specific Ra, or roughness
average. To obtain the desired Ra when applying thermal spray
coatings, we recommend following a unique sequence of steps
tailored to the substrate. A Ra of 2.5 to 5 on Tungsten Carbide,
for example, will likely require a film with grade 74u followed by
films 45u, 30u and 20u. It is important for operators to consider
these factors – Ra and substrate – when selecting the grade of film
for this belt.
Overall, this micron-graded diamond abrasive delivers the desired
finish without compromising the integrity of the substrate. Its
strength and versatility make it a suitable abrasive for your
finishing needs.
