Nov 08, 2019 · While for DOP higher than 50%, it is suggested to conducted the grinding process at a wheel speed (V s) higher than 53 m/s and maximum chip thickness (h m) below 0.78 μm, which could achieve a material removal rate (Q′ w) between 0.2 and 1.5 mm 3 /(mms) with a maximum surface roughness of 0.44 μm

modeling of vibration condition in flat surface grinding

modeling of vibration condition in flat surface grinding

The vibration conditions of the grinding system at the cutting speed of 25 m/s presented in Figure 5 indicate that there is a linear relationship between the dynamic instability of the flat surface grinding process and the rise of the cutting speed. The increases in the cutting speed cause an increase of the nonlinear vibration behavior of the process in both normal and tangential directions

experimental research on high speed grinding of silicon

experimental research on high speed grinding of silicon

Grinding is a main method of silicon nitride ceramic in finish machining stage. The technical parameters had an important influence on the surface quality of silicon nitride ceramic. The silicon nitride ceramic spindle was ground by the high-speed cylindrical grinder MGKS1432-H. The relations between different speed parameters and surface roughness were researched
