Optimization design of grinding wheel topography for high efficiency grinding
Journal of Materials Processing Technology, 2002Abstract In view of the limitation of prior topography models of the grinding wheel, a new method for optimization design of grinding wheel topography is advanced. The optimization model can be used to optimize the topography in accordance with machining demands and grinding parameters as well as optimize grinding parameters in accordance with the ...

The grinding efficiency of diamond burs
The Journal of Prosthetic Dentistry, 1979Deterioration of round diamond burs during 8 minutes of operation was found to be more pronounced for burs with low particle densities than for burs with high particle density. No definitive relationship was found between the initial grinding rate and initial particle density.

Investigation on cooling efficiency of grinding fluids in deep grinding
CIRP Annals, 2011Abstract The cooling efficiency of grinding fluids in deep grinding, at different material removal rates and grinding speeds, has been investigated. Two ‘inverse’ methods have been proposed to determine the level of convective heat transfer coefficients of grinding fluids, by matching the theoretical and experimental grinding fluid burn-out ...

Study on Grinding Burn in High Efficiency Deep Grinding
Applied Mechanics and Materials, 2013The high efficiency deep grinding is widely used in manufacturing. The experiments were carried out to study on the high speed deep grinding force and grinding burn and cracks in grinding 40Cr steel specimen with Al2O3 wheel. The experimental studies demonstrate that the grinding force increases with the grinding layer depth.

Efficiency improvement in internal grinding
Archives of Civil and Mechanical Engineering, 2006The paper deals with the effectiveness and the possibilities of its increasing. As an example the conventional inside diameter grinding using the higher-hardness grinding wheels at higher grinding speeds was considered. The analysis was carried out for different criteria. The method for determining the standard effectiveness index was proposed. Such an

Russian Engineering Research, 2008
Currently, abrasive machining is used to improve product quality and productivity and also for preliminary and final machining in a single pass. Deep grinding is of particular interest here. In this method, with considerable metal removal in a single pass, problems arise in preventing thermal and other damage to the part.

Influence of Clinker Microstructure on Grinding Efficiency in the Presence of Grinding Intensifiers
2020Grinding processes in cement production technology are quite energy-intensive. The mechanism of action of surfactants on the course of the clinker grinding process has not been fully studied. According to the theory of P.A. Rebinder, surfactants change the mechanical properties of solids in the process of dispersion of materials.

Highly Efficient Grinding of Ceramics and Hard Metals on Grinding Center
CIRP Annals, 1986Summary A machining center provided with necessary counterplans as a grinding center was used with a newly developed cast iron bonded diamond wheel in grinding of ceramics and hard metals. Highly efficient three dimensional form grinding was found to be possible by utilizing the rigidity and numerical control function of the machining center and the ...
