A method is therefore proposed to change the grinding wheel edge from parallel into inclined form so as to optimize the structure of abrasive layer.

点磨削砂轮磨料层采用有粗磨区修整倾角的结构可获得良好的磨削性能，较传统砂轮磨料层结构可获得更理想的磨后表面。

In these regulations 'blasting process' means the cleaning, smoothing, roughening or removing of part of the surface of any substance or thing including granite, stone or brick by the use as an abrasive of a jet of sand, metal shot or grit or other material propelled by a blast of compressed air or steam or water or by a wheel.

在本规例中，"喷砂工序"指使用喷射砂粒、金属砂或粗砂或其他物料作为磨料，并以喷出压缩空气或水蒸汽或水或利用轮推动磨料的喷射，从而清洁、磨滑、磨粗或除去任何物质或物件(包括花岗岩、石块或砖块)的部分表面的工序。

The results of the investigation showed that the best entrance angle of B〓C, B〓C/ C and Al〓O〓/ C ceramic nozzles is 11°, 14°and 16°respectively. Erosion wear model has been put forward. The B〓C and B〓C/ C nozzles exhibited a stress fatigue induced removal process under the condition of umber emery erodent impacting, and a brittle fracture induced removal process under the condition of white emery and SiC erodent impacting.

建立了不同磨损机理下的冲蚀磨损模型，提出了喷砂嘴的磨损属于多冲蚀机理并存的复合冲蚀机制。B〓C和B〓C/C陶瓷喷砂嘴在棕刚玉磨料的冲蚀下，主要表现为应力疲劳断裂冲蚀，在白刚玉和SiC磨料的冲蚀下，主要表现为脆性断裂冲蚀。
