Click on it2016213im just getting ready to fit a vfd to my surface grinder. the native speed at 50hz is about 2900rpm. i have a stack of 6 wheels which have a higher speed rating so i can fit a pot to control the spindle speed and my idea is to surface mount it somewhere prominent and make a scale that reads in rpm, but is it realistically going to be useful or an unnecessary complication
Click on it20181023drilling speeds and feeds . the speed of a drill is measured in terms of the rate at which the outside or periphery of the tool moves in relation to the work being drilled. the common unit and term for this velocity is surface feet per minute, abbreviated sfm. every tool manufacturer has a recommended table of sfm values for their tools.
