To improve the self-sharpening ability and increase clearance for debris of metal bonded diamond grinding wheel, the porosity structure is applied to the diamond grinding wheel in this paper. By selecting different inducers diamond composites are burned under appropriate agglomeration condition. The experiment results indicate that diamond composites obtained through two certain inducers can meet both the demand of pore-creating and intensity, so can be used to make wheels. This conclusion lays a foundation for further study.

In this paper, topography feature of the diamond grinding wheel under the diamond stylus elliptical ultrasonic vibration assisted dressing was studied experimentally. The results indicate that: the increase in dressing power of elliptical ultrasonic vibration will result in the increase in amplitude, and that can increase abrasive protrusion height of the dressing grinding wheel, and also increase the depth of chip pocket. With the increase of feed rate, surface peak and valley values of elliptical ultrasonic vibration dressing grinding wheel increase, that is the average protrusion height of abrasive grain increases. With the increase of dressing depth, surface peak and valley values of elliptical ultrasonic vibration dressing grinding wheel increases, while the number of static effective abrasive grain reduces. In comparison with the ordinary dressing grinding wheel, elliptical ultrasonic assisted dressing in the same parameters can bring about more static effective abrasive grain , more uniform abrasive distribution, a higher abrasive protrusion height and more chip space.

Machined Surface Roughness

Mill-grinding experiments were carried out on SiCp/Al to investigate effects of mill-grinding parameters and grinding wheel parameters on machined surface roughness in this paper. The machined surface topography was also analyzed. Experimental results show that surface roughness increases with increasing feed rate and the depth of the mill-grinding. The effect of mill-grinding speed on surface roughness is low. The machined surface reveals many defects. The fine grit diamond grinding wheel can reduce the surface roughness and decrease the machined surface defect. Compared to the vitrified bonded diamond and electroplated diamond grinding wheels used in the experiment, the resin-based diamond grinding wheel produces a better surface.

Wheel Loading

Advanced ceramic materials like sintered and presintered zirconia are frequently used in biomedical applications, where minimum quantity lubrication (MQL) assisted grinding is required to achieve a good surface finish instead of conventional flood coolant. However, insufficient cooling and wheel clogging are the major problems that exist in the MQL grinding process, which depends upon the type of work piece material and the grinding wheel being used. The present study is to determine the performance of the grinding wheels on presintered zirconia under MQL conditions in terms of grinding forces, specific energy, surface integrity, and wheel wear. Experiments are conducted with two different types of grinding wheels as silicon carbide (SiC) and diamond grinding wheels under the same condition. The results indicated that the diamond wheel provided a better surface finish and reduced tangential force under MQL condition, compared to the conventional SIC wheel. This was due to the reduction of wheel loading in the diamond grinding wheel. The specific energy of diamond grinding wheel was reduced with higher material removal rate compared to the conventional SiC wheel. The ground surfaces generated by the diamond grinding wheel showed fine grinding marks with better surface finish. The percentage of G-ratio calculated for the diamond wheel was higher than the SiC wheel by 77%. This was due to the sliding of the grains and less wheel loading in the diamond wheel. The cost difference between the corresponding wheels was discussed to improve the productivity of the grinding process.

A new type of brazed diamond grinding wheel with a rotating heat pipe is developed to effectively remove the heat generated in the grinding zone meanwhile minimize the pollution and contamination of the environment. A grinding temperature-measurement experiment of titanium alloy was conducted to evaluate enhanced heat transfer effect of the rotating heat pipe on the grinding zone. The experiment results show that, when grinding using the wheel with heat pipe the grinding temperature decreases 30% than that using the wheel without heat pipe.

It is aimed at developing a new diamond wheel in order to overcome the shortages of traditional grinding wheel, such as the abrasive easily fall off the grinding wheel prematurely, high grinding temperature, random grits distribution and the loading problems become more severe in grinding process. And further study on the grinding temperature of the new diamond wheel prepared in comparison with traditional resin-bonded diamond grinding wheel in machining Al2O3 ceramic. The prepared new diamond wheel has many diamond fibers involved in grinding process which are artificially ordered, diamond grits are not easily fall off, and it has big chip-pocket space and heat dissipating capability. The experimental results indicated that the grinding temperature of the new diamond wheel in comparison with the conventional diamond wheel under the same conditions was decreased by 80°C-120°C.

Surface and subsurface damage affect the preparation of high-resolution HgCdTe and CdZnTe detectors. Grinding experiments were performed on CdZnTe substrates with the grinding wheels of different abrasive sizes. The surface topography and subsurface damages of CdZnTe substrates ground by diamond grinding wheels with different grit sizes were studied. The effects of the grit sizes of grinding wheels on the surface topography and subsurface damage of CdZnTe substrates were discussed. The surface roughness and subsurface damage layer depth of CdZnTe after grinding with #3000 diamond grinding wheel are only Ra 7 nm and 100 nm, proved that grinding is of great potential for CdZnTe substrate processing.

Dimensional Surface

Surface measurement using three-dimensional stylus instruments is a relatively new technique that offers numerous advantages over more traditional profilometry methods. The information generated is, unlike profile measurement, less subjective and more statistical providing additional insight into the surface structure. One application of surface measurement that has encountered problems when using the profilometry method is that of grinding wheel characterisation. The wheel surface texture (topography) and the conditions under which it is generated have a profound effect upon the grinding performance as characterised by the grinding forces, power consumption, temperature, and surface integrity of components. A detailed knowledge of the nature of the topography of the grinding wheel would provide further insight into surface interactions between the wheel and workpiece as well as enabling improved control of the grinding process in general. In this paper four diamond grinding wheels of 91 and 181 micron grit size were subjected to differing dressing conditions to produce varying final wheel topographies. Three-dimensional surface measurement techniques were employed to quantitatively characterise the topographic change and provide an aerial estimation of the number of cutting grains. The results demonstrate that the techniques can distinguish between a worn and dressed wheel. In addition, the parametric values generated from the various surfaces can aid the user in determining when re-dressing is required.
