In this paper, an experimental study was conducted to compare the sawing of granite with thin and normal blades. The power drawn by the spindle and horizontal and vertical forces were measured. The width of sawing slot on the granite was examined after sawing. For both blades, power and forces increase with the depth of cut. The width of sawing slots for the thin blade was about 75% of the normal blade. The width of sawing slots for either thin or normal blade sawing became narrower in larger depth of cut.

In this present work, an experimental study was carried out to investigate the wear of metal-bonded diamond tools (specimens) in five abrasive processes – stirring diamond specimens in rock slurries and surface grinding the specimens with a vitrified alumina wheel as well as circular sawing of refractory bricks, vitrified silicon carbide wheels and natural granite with segmented diamond blades. Three diamond specimens of different hardness were fabricated by hot pressing. In addition to following the worn morphologies of the diamond tools, forces and power were also monitored in four abrasive processes. During stirring and surface grinding, the wear of the diamond specimens decreased with increasing specimen hardness, whereas the vertical force in surface grinding increased with the specimen hardness. In sawing of granite, however, the wear of the blades was closely related to the vertical force generated in sawing rather than the hardness of the diamond segments. The trends of force changes in sawing of refractory bricks were comparable to those in sawing of granite. But the force ratios in sawing of the SiC wheel were found to be much higher than those in sawing of other two materials.

This paper aims to investigate the machining characteristics of surface ground by fixed abrasives. Face grinding experiments of aluminum block are done. Different surface in experiment are generated through change of processing time while keeping other experiment parameters unchanged, and those tests of surface strain and roughness of aluminum blocks are conducted. The magnitude of stress and roughness on sample after experiment increases with processing time, which is also fit for the change of the above index parameter between before and after experiment. Larger surface stress of sample on which higher surface roughness is also seen is found in present investigation. The most helpful findings in experiments indict that engineering in workshops will get the method to achieve the product with high performance, when decreasing the surface stress and roughness and extending service life.

Polishing the titanium plate is commonly necessary step before being used in many fields. Experiments of the titanium plate polished in the condition of including abrasive and existing abrasive are carried out to study the roughness of polished surface in given state. Surface roughness and morphology were investigated in experiments and experimental results were analyzed. In both experiments, the polished surface roughness value reduces with increase in processing time, and the detects on titanium plate before polishing decreases, which attributes to the mechanical and chemical tooth rising from lap between workpiece and polishing machine with the help of energy required. Material removal block in abrasive polishing is higher than that in case of existing abrasive. This helps to deepen the understanding of change in roughness of surface polished and indicates the promising operation technology for processing titanium in factory and workroom.

This present paper aims to investigate the effect of abrasive grinding on characteristics change of surface in fixed abrasives grinding. Different surface in experiment were generated in surface grinding through change of processing time while other experiment parameters remained, and those tests of surface strain and roughness of SUS304 strip were conducted. The magnitude of stress and roughness on sample after experiment increase with processing time, which is also fit for the change of the above index parameter between before and after experiment. Larger surface stress of sample, on which higher surface roughness is also seen, is found, and simultaneously, the dependable correlation between surface stress and roughness in grinding is appraently shown. Theose decsribed findings brings out direct help to researchers and practiitioners in industry engineering fields when searching for the soution of decreasing the surface stress and roughness and extending service life of product with high performance.
