Diamond Polishing Film

Grish Polishing film is manufactured with the most advanced super precise coating technique in the field, comprised: mixing the precisely graded abrasive particles ( such as diamond, aluminum oxide, silicon carbide, silicon oxide, cerium oxide and so on) with the advanced polymer material to form a slurry; uniformly coating the slurry on the high strength film backing.
Beijing Grish is always devoted to develop and apply a full range of new polishing products which are used in fields such as fiber optical connectors, computer, semiconductor, LCD, and automobile. We are committed to provide high quality precision polishing products. Besides we also offer superior customer services on new product development, application research and technical support and so on .

Features:

� Apply specified mixing technique to ensure abrasive minerals uniformly coated on film

� Bond with high strength epoxy to provide long durability and exhibit a long life on film use

� High quality and excellent consistency

� High cutting rate as featured in solid polishing material such as sanding wheel, also reaches high polishing rate as using polishing slurry

� Good strength reaches good arc polishing effect

� Can be used for dry polish, also for polishing used water or oil

Note

1. Cerium Oxide CO and Silicon Oxide SO are mainly used in film with small particle size for precise polishing;

2. Other film sizes are available upon request.

Application:

� Fiber optical connectors, couplers, attenuators

� Ceramic & plastic ferrules, pigtails

� Optical lens, optical crystal, Sapphires, optical glasses, LED, LCD

� Magnetic heads, hard discs

� Semiconductor wafer ( gallium arsenide, indium phosphide etc.)

Suggested Process:

Taking fiber optical connector as example, instructions step by step are as below:

Prepare polishing film: prepare the proper polishing film depending on polishing machine type, optical connector type and size.

Polishing film SC30 is normally usded for resin remove, D9 for coarse polish, D3 for medium polish, D1 for fine polish and SO0.01 for final polish.

1. Clean rubber back-up pad: clean rubber back-up pad or glass back-up pad thoroughly to ensure polishing film backing has the better contact with back-up pad. Spray pad with appropriate amount de-ionized or distilled water, make sure the water tension hold the film evenly and does not move when polish.

2. Clean polishing film: Place film on polishing surface, spray film with de-ionized or distilled water, wipe surface with a clean tissue. The goal is to remove the air bubbles, smooth out the film and clean the surface of the film, this can improve polishing result and prolong film durability.

3. Place polish film on polishing plate and secure the loaded polishing jig into place: load and take out the jig carefully and avoid damaging jig and scratching polishing film surface.

4. Start polishing: Start polishing after adjusting desired time and pressure setting. Clean completely after each step. All types of Grish’ s polishing films can be used repeatedly.

Customer can follow the steps describe as above in general. However, depending on user’ s particular condition and unique quality requirements, the polishing films and polishing steps used in polishi process could be vary.

Important Note:

1. Store in cool and dry place

2. Keep away from organic solvents
