Grinding Force Ratio. Grinding force ratio is a parameter that gives indirect information about the efficiency of grinding. Force ratio is defined as: (2.8) When grinding with sharp wheels grinding force ratio is high since normal force is low compared to tangential force. Conversely, when grinding with blunt wheels grinding force ratio is low.Fundamentals of Roll Cooling and Control of Flatness at ,Footprint Geometry Effective and precise Footprint Geometry is the fundamental requirement to establish a Homogeneous Cooling application and is achieved by the configuration of a uniform Cooling Area on the work roll, formed by the impingement of an array of adjacent sprays, equally spaced and positioned to assure consistent SIZE REDUCTION akahl,Number of rollers 3 5 3 4 3 6 Roller speed m / s 2,5 2,5 2,5 Drive motor kW / min1 160 200 / 1500 200 250 / 1500 200 315 / 1500 Type 55 1500 65 1250 60 1500 Die diameter mm 1500 1250 1500 Roller diameter / width mm 450 / up to 240 450 / up to 190 450 / up to 240 Number of rollers 4 6 4 5 4 6
Runout, or TIR is a measurement of the relative accuracy between all the diametrical planes of the base.. Size of the base is determined to accommodate the amount of copper that the Engraver requires for their process, typically between 0.012” and 0.020” in diameter.. Finish of the base body needs to be suitable for the copper plating process..

The Benefits of Thread Rolling. The fastest, most economical method for producing highly accurate threads, thread rolling allows for higher repeatability, stronger threads, and better finish quality and mechanical properties than grinding, cutting, or chasing.
