Non-stop H igh-speed Punch i ng Mach i ne
. . .. .' !
LIBRA features non-stop, high-speed processing, making a phenomenal line speed possible.
For punch i ng by tu rret method , a work sheet is moved back and forth as we i l as rig ht to left to a l ig n with punch i ng pos it ions .
To the cont rary, L I BRA processes a wo rk sheet seq uent i a l l y f rom its edge , so the mate r i a l on ly moves fo rward .
With th is fo rward movement , the f ront X-ax i s carr i age and the rear A-ax is carr i age repos it i o n to t ransfe r the mate r i a l ,
and the p rocess i ng on the A-ax i s (the l atte r ha lf part) w i l l be pe rfo rmed cont i n uous ly.
At the same t ime as the A-ax i s process i ng , the I oad i ng (o r i g i n set) of the next wo rk wi l l be comp lete .
I n th i s man ne r, p rocess i ng wi l l be pe rfo rmed from mate r i a l to mate r i a l without paus i ng .

I he materia l moves from the X-axis to theA-axis d i rection .
I t the same time, the stri ker moves to theU-axis / V-axis d i rections for punch i ng .
ONon-stop operation wastes no t ime selecting a tool .The too l b lock swift ly moves when transfe rr i ng a material . At the
same time , the striker moves along on the too l , i nstantly se lecti ng
a requ i red tool to perform punch ing . Therefo re , the time spent toselect a tool is practical ly zero .

== H i g h / I ow p ressu re sw i tc h hyd rau l i cd riv i ng methodUsing a d igital servo valve makes it possible to qu ickly

mHigh rig id ity / bridge frameDual structu re consists of "bridge frame" wh ich
supports the body of the processing machine and"tool block frame" that supports the tool part. Thisreduces impacts caused by press Ioad such asdef l ectio n or thermal defo rmat io n , and makes
accurate and stable processing possible . Also , h igh
