1. The abrasive grain is impregnated in nylon.

2. The test results of abrasive grain constitution showed that the standard sands and can assure high testing accuracy is capable to unify the testing result.

3. The basic pattern of abrasive grain erosion is studied on four kinds of macromolecular materials, and relative regression equations are worked out.

4. With the increase of grinding speed or the abrasive grain size of the grinding belt, the grinding rate increases.

5. The influences of abrasive grain size, belt speed, contact roller's hardness, grinding depth and grinding feeding speed on surface roughness were discussed.

6. Abrasive grain erosion is the basic wear form on the tapered liner in desilters and desanders.

7. What is the abrasive grain being used, aluminum oxide, silicon carbide, zirconium etc? - Especially for the last pass.

8. Abrasive grain up only 30 % weight; its self - sharpening action is weaker, resulting in lower grinding efficiency.

9. The magnetic abrasive grain is the key factor which impedes the development of magnetic abrasive finishing.

10. Abrasive grain makes up only 30% weight; its self-sharpening action is weaker(sentencedict.com), resulting in lower grinding efficiency.

11. For the two kinds of abrasive grain—ordinary abrasive and ultra hard material, carborundum and diamond were chosen as samples for dispersing experiment.

12. In this report, the surface morphology of marble in face grinding with single abrasive grain has been observed by SEM.

13. The stress and grinding mechanism of a single magnetic abrasive grain in the magnetic abrasive finishing are analyzed. The required properties and preparation technologies of MAGS are discussed.

14. The second principal normal stresses can lead to grinding crack which generates forward beneath the abrasive grain in the plane of grain motion.

15. Our hand pads are cut from industrial quality non-woven nylon, impregnated throughout with abrasive grain and boned with heavy duty resins.

16. A method for detecting the protrusion height of diamond abrasive grain on diamond wheel was proposed based on the digital image identification technology, and the measuring system was established.

17. If the undeformed chip thickness is reduced, the effect of the top part of the abrasive grain will increase.

18. In this paper , metal - bonded diamond wheels of different sized abrasive grain with different porosity were fabricated.

19. The phases can improve the bonding strength between coating and matrix. The abrasive grain resistance of the coatings is 11.26 times as great as copper, the adhesion resistance is 7.97 times.
