SFM is a combination of diameter and the velocity RPM of the material measured in feet per minute as the spindle of a milling machine or lathe. 1 SFM equals 0.00508 m/s meter per second the SI unit of speed . The faster the spindle turns and/or the larger the diameter the higher the SFM. Surface Feet Per Minute. SFM = .262 x D x RPM. Nhận giá
