Can be used to add lathe tools, manual twist drill, the workers end mill, the ball milling cutter head, ladder drill, reamer, forming cutter, deep hole drilling, triangle chisel and shape tools, etc. Feeding system adopts fully closed structure, no hacking device, built-in liquid cooling cycle device and cutting oil mist recycling equipment. The motor shaft by unit by high precision no clearance coupling and precision the ball screw vice straight league, no clearance error. The smooth movement and high driving accuracy, not easy wear and long service life. Guide all adopt the coattails type precision ball linear guide, with high precision, small friction coefficient, life is long, etc. Guide, the ball screw vice using a cooling device of automatic timing quantitative lubrication system. And in PROE draw in the Z axis into 3 d model picture to the system, and to generate two-dimensional engineering graphics. Key words： Gang center
