CNC black bar peeling machine working fundamental principle,The spindle is driven by the main drive through the synchronous belt drive gear box, then drives the cutter head which is equipped with four adjustable tool holders to produce the precision and high speed rotation movement. Rod is feed in through the front feeding clamping, and is given a linear and feeding motion. Front guide makes the central location to the bar, and after that, the cutter head begins to peel the bar on the surface. After peeling, the bar enters to the middle and rear guide part to experiences another central location. The extracting components deliver the after-peeling bar to unloading rollers.
