What Everyone Ought To Know About 3M Diamond Lapping Movie

What are lapping movies?

Lapping films are skinny polyester films coated (resin bonded) with tightly graded abrasive particles similar to aluminum oxide, silicon carbide, cerium oxide or diamond. The popular particle grades (particle measurement measured in diameter) are 0.05, 0.1, 0.3, 0.5, 1, 1.5, 2, 3, 5, 6, 9, 12, 15, 20 and 30 microns. (One micron is about 1/50 of a human hair diameter)

The applications for lapping films range from polishing fiber optics, optical components, ceramic capacitors, pc hard drive read-write heads, ceramic seals, etc. The main attribute of lapping movies is that they produce very flat surfaces, particularly throughout supplies having a wide range in hardness.

What are lapping movies used for?

Lapping movies are used for lapping and sprucing a substrate to realize super-effective, highly consistent finishes. Their major purposes include fiber optic connector sharpening, magnetic heads, floppy disks, magnetic media, metals, plastics, oxide disks, etc.

Why are diamonds used in these lapping movies?

Diamond is among the hardest supplies on earth. So diamond particles are used to polish some very laborious materials reminiscent of ceramics, glass, carbide, composites, unique alloys and other arduous supplies that aluminum oxide, silicon carbide or other abrasive supplies cannot handle.

What kind of substrates can 3M diamond lapping film polish?

3M diamond lapping film can be utilized on ceramics equivalent to zirconia (materials used on fiber optic connector ferrules), glass, carbide, stone, exotic alloys, etc.

Are there various supplies than diamonds?

Yes. Lapping films with other sort of abrasive particles comparable to aluminum oxide, silicon carbide, cerium oxide are much more widespread due to their low cost.

What are the benefits of using 3M diamond lapping films as an alternative of cheaper aluminum oxide or other abrasive lapping films?

1. Lengthy life
2. Produces superior floor finish
3. Reduces total process time
4. Produces excessive yields
5. Constant results all through lifetime of product

What varieties can be found of these lapping films?

3M diamond lapping films come in shape of sheets, discs and rolls. The maximum width is 12 inch. The most popular sizes utilized in fiber optic connector polishing include four inch disc, 5 inch disc and 6x6 inch sheet.

The 3M diamond lapping movie shade code for diamond grit size

Each lapping movie producers might use their own color code to distinguish between completely different particle sizes. For 3M diamond lapping movies, the colour code is as follows:

0.1 micron – green, 0.5 micron – white, 1.zero micron – lavender, 1.5 micron – gentle green, 3.0 micron – pink, 6.0 micron – brown, 9.zero micron – blue, 15.zero micron – orange, 20.0 micron – burgundy, 30.0 micron – green, 45.zero micron – amber, 60.0 micron - amber

How do you retailer 3M diamond lapping films and what are their shelf lives?

Although the storage of lapping movies often do not require special situation, the recommended storage temperature is 10~32°C, relative humidity if 30~70%. It's endorsed that the product needs to be used inside 2 years of purchase.

3M Diamond Lapping Film Discs are available for wet or dry (W/D) functions with Stress Delicate Adhesive (PSA) or Plain Back from 0.1 micron to 45 micron. Special dimension orders are additionally available.

3M Diamond Lapping Movie Discs or Sheets have a longer life and are really useful for important applications. Out there in discs and sheets from 0.5 micron to 9 micron. Particular measurement orders are also available.
