Semi automatic metal tube peeling machine is an important process in metal tube industry. As there is hollow in tube , wall thickness is required upon peeling machine choice . Usually wall thickness : outside diameter is 1: 15 . If tube wall thickness too small , pressure from roller of peeler could destroy tube . Semi auto metal tube peeling machine , compared to CNC peeling machine , require operator has high skill in machine adjustment when changing cutting depth on metal tube. Metal tube peeling machine is usually composed of main machine , table bed, air/oil lubrication system, cutting fluid circulation cooling system, chip conveyor, hydraulic system and electric system,etc.
