Speed Spindle - an overview | ScienceDirect Topics

High-speed spindles are the heart of HSM operations with typical ratings of 30 hp/30 000 rpm to 50 hp/20 000 rpm. The typical elements of a spindle are the tool interface, the drawbar, the spindle shaft, the bearings, the driving system, the cooling system, and the housing as shown in Figure 4. There are several types of driving systems
