The machine adopts 45° integral oblique bed structure, strong structural rigidity, suitable for heavy milling processing, strict internal defense design makes the processed iron chips can be well isolated, and the processed iron chips can automatically enter the chip removal system without manual cleaning, and the loading and unloading workpieces of the machine tool is very close to the operator, and the feeding height is relatively low, which can greatly reduce the labor intensity of the operator. Due to its good rigidity, it can improve the cutting speed, smooth chip removal, reduce iron scrap cleaning time, and reduce labor intensity at close feeding distance, etc., so it has higher processing efficiency and more stable performance than flat beds.
