The ELID grinding process exhibited significantly lower subsurface damage compared to the conventional grinding process. It appears that the ELID grinding process has great potential to meet the challenge of faster finer and cheaper machining of silicon wafers. More studies and planning are however required before implementing the ELID

One process for hard finishing gears is generating gear grinding.Due to its high process efficiency generating gear grinding has replaced other grinding processes such as profile grinding in batch production of small- and middle-sied gears
2014-6-136. Conclusions Fine grinding of silicon wafers has some unique requirements regarding the grinding wheels the grinder design and the process parameter optimiation. Experiments have been conducted to explore the effects of the grinding wheel the process
A novel GCC grinding aid was prepared by aqueous polymerisation. The following optimal synthetic conditions were determined by grinding experiments weight ratio of monomers 2-acrylamido-2-methyl propane sulphonic acid AMPSacrylic acid AA 14 weight ratio of isopropanolwater 1.25 reaction temperature 80 C reaction time 5.5 h initiator dosage 4 wt. based on total monomers and
Compared with surfaces that had been polished surfaces that had been mirror-finished by grinding process exhibited superior surface properties including hardness tribological and fatigue properties corrosion and high-temperature oxidation resistances and adhesive strength with coating films

Grinding machines can process harder materials such as hardened steel and hard alloys they can also process brittle materials such as glass and granite. Grinding machines can be used for grinding with high precision and surface roughness as well as for highly efficient grinding such as strong grinding. History of grinding machine

In our research SPI exhibited rough particles with broken edges and similar sies and SPII exhibited agglomeration of broken particles. This indicates that the breakage was dominant in SPI and the agglomeration was dominant in SPII Zheng et al. 2018. Thus grinding treatment had a marked mechanochemical effect on BFU powders
2018-6-28In addition the wear morphology exhibited that abrasion flattening occurred not only on the CVD diamond grain tips but also on the side edges of the micro grooves. This implied that the micro-structures effectively participated in the grinding process and thus resulted in an increase in the grain density and enhancement of the cutting effort

2016-9-9The process is purely physical and does not depend on parameters such as the temperature or wafer doping con-centration. Precision grinding of silicon proceeds in two stages coarse grinding followed by ne grinding. During the coarse grinding stage the wafer and grind wheel rotate at 200250 rpm the removal rate of silicon is about 250
