Understanding Forces in Creepfeed Grinding for Reducing Costs
网页0.38, and the specific grinding power is just over 10 Hp/in. When developing new creepfeed grinding applications, it is common to estimate the spindle power requirements in the range of 12-18 Hp/in to initially develop the process. These values can also be used to estimate grinding forces on new fixture and part designs for new applications.
