“…Zhao and Guo [22] recently used three different wheel conditioning methods consecutively for electroplated diamond wheels in order to enhance their performance in the ultra-precision grinding of optical glasses. Firstly, they used a metal bonded diamond cup wheel with a lower grain size than the grinding wheel with two purposes: to minimize the runout and to flatten the grains to the bond layer level in order to enhance the finishing.…”

Cubic boron nitride (cBN), in addition to diamond, is one of the two superabrasives most commonly used for grinding hard materials such as ceramics or difficult-to-cut metal alloys such as nickel-based aeronautical alloys. In the manufacturing process of turbine parts, electroplated cBN wheels are commonly used under creep feed grinding (CFG) conditions for enhancing productivity. This type of wheel is used because of its chemical stability and high thermal conductivity in comparison with diamond, as it maintains its shape longer. However, these wheels only have one abrasive layer, for which wear may lead to vibration and thermal problems. The effect of wear can be partially solved through conditioning the wheel surface. Silicon carbide (SiC) stick conditioning is commonly used in the industry due to its simplicity and good results. Nevertheless, little work has been done on the understanding of this conditioning process for electroplated cBN wheels in terms of wheel topography and later wheel performance during CFG. This work is focused, firstly, on detecting the main wear type and proposing a manner for its measurement and, secondly, on analyzing the effect of the conditioning process in terms of topographical changes and power consumption during grinding before and after conditioning.

“…[12][13][14] However, these applied fine-grained diamond wheels have the disadvantages of a large grinding wheel wear rate and a small material removal rate, which undoubtedly limit the achievable grinding accuracy and efficiency. 15 By contrast, a coarse-grained diamond wheel features a much higher grinding efficiency. However, coarse-grained diamonds tend to form a rougher surface morphology, and the wearing of the diamond grit leads to a reduction of the quality of the machined surface.…”

An electrolyte containing carbon microspheres (CMSs) was prepared for electrolytic dressing of a multi‐layer brazed coarse‐grained diamond wheel. And the influence of CMSs on the electrolytic in‐process dressing grinding performance of Si3N4 ceramics with the brazed wheel was investigated. The results indicate that the CMSs can increase the electrolytic capacity of the electrolyte, which increases the thickness of the oxide film formed on the brazed wheel surface, and the worn diamond grit can easily fall off from the bonding matrix. In addition, the CMSs were adsorbed and distributed on the film, which effectively improves its densification and adhesion strength. This thicker and denser oxide film can improve the polishing effect of the brazed wheel. Thus, a better machined surface quality and less subsurface damage of the Si3N4 ceramics can be obtained by the multi‐layer brazed coarse‐grained diamond wheel with electrolyte containing CMSs.

“…In addition, although laser profiling could achieve higher accuracy, during ultra-high precision grinding, a surface circular runout of approximately 2 m is normally required. For example, Zhao et al [7][8][9] of the Harbin Institute of Technology used a cup-shaped diamond wheel combined with inprocess electrolytic sharpening to dress 91-m diameter grains of an electroplated diamond wheel. The circular error was reduced to within 2.5 m, and the surface roughness of the workpiece ground by the wheel was 20 nm.…”
