Feb 01, 2015 · Similar results were obtained by Yoshio in high speed grinding of bearing steel, which showed that the grinding energy at a grinding speed higher than 200 m/s was reduced by 20–30% compared with that at the conventional grinding speed of 60 m/s, and that the reduction of surface roughness was mainly due to the reduction of the side swelling formed along both sides of the groove …
High Speed Grinding (HSG) is a new and unique grinding technology based on very high working speeds of more than 80 km/h. This allows rails to be ground without the need for possession time and/or track closures. The main application area is preventative grinding to avoid rolling contact fatigue and corrugation.

Oct 18, 2019 · Reducing the generation of frictional heat can reduce internal and external friction during grinding. This should take into account the following factors: reduce the grinding thickness, making the reduction of plastic deformation of the metal, reducing the internal friction and grinding heat
Jun 05, 2021 · By combining the cycle time reduction created by implementing new grinding wheels and creating an innovative wheel dressing station, the MSC team had saved 119 minutes of grinding per shaft as well as an additional 114 minutes per part on non-cutting traversing for diamond wheel dressing — a 233-minute saving per part in the grinding cell
Jan 26, 2021 · Reduce feed rate. Reduce depth of cut. Increase the number of spark-out passes. Outer-diameter (OD)/Internal-diameter (ID) grinding: Increase wheel speed. As mentioned before, the wheel must be rated to run at the new speed. The maximum operational speed will be stated on the side of the wheel. Reduce depth of cut per revolution
On the other hand, very low grinding wheel speeds, in the order of 3,000 to 4,000 fpm (about 15 to 20 m/sec) are needed for the surface grinding of various types of high alloy and high strength work materials, using the lower wheel speed as a means for minimizing the development of heat, to which certain types of materials and workpieces are particularly sensitive
May 01, 2021 · However, the grinding/cutting speeds are still low in above-mentioned studies, generally lower than 40 m/s, which limits the material removal rate. Increasing the machining speed is an effective way to achieve high machining efficiency
