|PR message||PJ812 is renowned as the "Ultimate Mother Machine" that realizes exceptional high quality in profile machining with Jig Borer level positioning accuracy.
J350G's advanced features include the out-feed stroke 53mm extended from previous 2mm, significantly improving the productivities in contour chopping grinding process for various diameter holes.
|The Main Item||
Precision Profile Center PJ812 and High Precision Jig Grinder J350G
|The name of Item||Precision Profile Center PJ812|
（２）Table Working surface：1,200mm×800mm
（３）Spindle taper/rotation speed：BT40/30,000min-1
・Ultimate mother machine realizes Jig borer high accuracy positioning and High accuracy contour machining.
・Planer type symmetric construction reduces heat deformation.
・Achieves 0.1um axis feed,using a new"Mitsui Seiki"designed slide way mechanism,and adapting centralized cooling system for ballscrews,slideways and critical surfaces.
・New multi sensor thermal growth monitoring system controls Z axis thermal displacement approximately 35% better than previously used technologies.
・New PJ812 design minimizes the distance between the spindle center and Z axis drive thereby improving the static rigidity of the system 6 times more than conventional machine designs.
・New Energy saving circuitry reduces"idle time"power consumption by 90% and compressed air consumption by 40% over previous designs.
