When Wet Streaks Return, Reevaluate Your Rolls!

Aug 24, 2017· If wet streaks prevail, chances are, your rolls are out of spec. It’s that simple. Most roll grinding services are not able to achieve OEM specifications, even OEM’s who often outsource roll grinding work. Remember! The OEM’s primary focus is the manufacturing and assembly of equipment, not roll grinding.

Ductile streaks in precision grinding of hard and brittle

Ductile streaks produced during diamond grinding of hard and brittle materials have aided the subsequent process of polishing. Two novel techniques were used to study the formation of ductile mode streaks during diamond grinding (primary process) of germanium, silicon, and glass. In the first technique, aspheric surfaces were generated on Ge and Si at conventional speeds (5000 rpm).

Experimental Study on Surface Integrity and Subsurface

Feb 12, 2021· With the decrease of depth-of-cut and the increase of wheel cutting speed, the ultra-precision grinding changes to ductile-regime grinding with plastic flow removal. Besides, the surface roughness (SR) and SSD depth are reduced. The fracture defects such as fractured pits and grinding streaks on brittle-ductile surface gradually decrease.
