11.Finally,the most reasonable technological process of“stagewise grinding,coarse and fine classification,gravity separation magnetic separation reverse anionic flotation”has been found out.
12.Newly developed semi automatic grinding wheel balancer for precise grinder detects unbalance vibrative signal by digital phase sensitive detection technique.
13.It has properties of hardening after malleablization,arc welding and impact resistance.It can grind but can not machining demagnitized steel-bonded carbide.
14.Bruxism is a disorder characterized by grinding and clenching of the teeth, companied with fasciculation of masticatory muscles in nonfunctional status.
17.Applying a photopolymer resin instead of thermopolymer resin as a bonding material,a rapid manufacturing of grinding wheel is realized on the basis of rapid prototyping.
18.In this paper,the mechanism of workpiece burn during grinding of casehardened steel and titanium alloys was studied by the use of SEM,EPMA,XPS and the metallograph analysis.
19.Later, senior official thinks to be done so appear insufficient respect, convert cloth includes mandarin orange, afterwards, often fear whether delaine can grind attaint mandarin orange again.
20.By applying a photopolymer resin instead of the thermopolymer resin as a bonding material,a rapid manufacturing processing of grinding wheel is realized on the basis of rapid prototyping.
