WM SERIES CNC PRESS BRAKE

As a high performance board bending metal form machine, MILAN brand electro-hydro synchronized CNC press brakes provides widely industrial applications in aviation, shipbuilding, railway,electrics, mine,engineering mechanics, metallurgy, automotive, agricultural mechanics, light industry, instruments and machine tools that Sheet Metal forming process lies. When slide block accomplished a stroke up & down the metal board was formed into a certain geometric shape and come along to become a more complicated cross section by multiple presses or using variable moulds.

7.Specifications:
(1)Cylinder's compensation
Compensation via multi-cylinders, which are put inside the working table. This system is controlled by CNC and works automatically and conveniently based on the powerful expert software.



(2)Deflection compensation
To ensure the bending angle tolerance within +/- 0.5°
Mechanical compensation works through precision wedges, which moves under CNC. This system can make the perfect crowning curves to match the ram deflection well, so that reach the precise bending.
Motorized and manual types are available.

(3)Principle of Synchronized close--loop


Uses the advanced electro-hydraulic synchronization technology, the Y1~Y2 axis are the 2 cylinder independence movement parameter which is controlled by numerical control systems . Install two Hyde grating ruler on both sides of the machine tool, they are used for to determine the accurate distance between the slide and work table. The grating ruler (C shape frame) connects the work table through the small rack, which maximally eliminates the influence to the slide position caused by column deformation . When slide is moving, the data is reflected immediately to the numerical control system, then it may calculate and out put servo valve control signal S1~S2, to control two electro-hydraulic servo valve's output flow and make two oil cylinder synchronous,this position measurement process is a closed loop control.
