1) 10 tons of press, whether open or closed, does not represent advanced technical performance. When the nominal force is below 400KN, the zibo punch of two kinds of bed has no effect on the performance of machine tool fundamentally. In processing and manufacturing, user operation and inspection, open bed is better than closed. Of course, large tonnage Zibo punch in the same bed weight, closed bed to reduce the deformation of machine tools. Although most of the manufacturers are currently consuming open bed CNC punch, it can not be said that this is the development trend of CNC punch, and then deny the closed mechanism.


AMADA and KOMATSU use dual construction racks to improve machining accuracy and die life.


(2) the plate is sent into the positioning of X, Y two axis and the selection of touch axis T axis is the three basic CNC punch axis. It is common practice to have zibo punches with straight moulds arranged on X-axis beams by Trumpf Company of Germany and CNC punches with array moulds arranged by Salvagnini company of Italy. The former chooses the mold axis and the X axis are combined into one, while the latter does not choose the touch axis as long as two axes. Without thinking about these two conventions, the fourth axis of CNC punch is the mold axis C axis, the fourth and fifth axis is the C1 and C2 (follow the axis) axis of the mold axis. At present, manufacturers have no longer consumed 3 axis or CNC punch without rotary mill. Rotary spindle will no longer be optional for CNC presses, but essential.


(3) turret mold library is the mainstream form of Zibo punch mold library, this mold library structure is simple, large capacity, reasonable mold structure, mold change speed, easy to disassemble and assemble. Punch knife library type mold library is derived from the knife library and the form of gold cutting machine tool, now as long as the Italian Omes company, WHITNEY company in the United States, the German Trumpf company has eliminated the knife library type structure and unique to create the in-line tool library.
