Main spindle box lower end is equipped with main axle cutter, main spindle box lower end to workbench distance >=100-680 mm.
The present invention not only has a standard feature of traditional machining center (CNC), and can be equipped with tool magazine capacity is 1-24 the disc type tool magazine of cutter simultaneously, with automatic tool changer needs during satisfied cutting, can complete milling, boring, bore, cut with scissors, the machining of the working procedures such as tapping.
Be furnished with on workbench multiple can vertical telescopic (Z-direction) in the alignment pin (be hydraulically operated pump A drive) of table surface, block the left and right side of workpiece to be processed, prevent workpiece from moving left and right (X-direction) on the table.
The pressure measurement pin (being hydraulically operated pump B to drive) of multiple can stretch (X-direction or Y direction) it is fixed with in table top upper horizontal on workbench, withstand left and right side or the front and back sides of workpiece, prevent workpiece from moving left and right (X-direction) or movable (Y direction) on the table.
It is fixed with the top pad (being hydraulically operated pump C to drive) of multiple can stretch at workpiece upper vertical (Z-direction) on workbench, push down the upper surface of workpiece so that workpiece is pressed on table surface and is difficult to left and right, movable or rotation.The piston rod of fluid clutch C is connected with top pad by waling stripe, and waling stripe can do the rotation (having cradle head) of 90 degree around piston rod, adds at workpiece surface and will not hinder the movement of process tool man-hour.
Separately having control system, control system connects control respectively and drives pump A, drives pump B, driving pump C.Alignment pin, pressure measurement pin or top pad are to the pressure size of workpiece respectively by control system control, and the fragile workpieces such as graphite are added and are particularly important by this man-hour.
When the upper surface of processing workpiece or lower surface (work piece hoisting stands up post-treatment lower surface), control system controls to drive pump A to drive, and alignment pin is flexible, drive pump B to drive pressure measurement pin to stretch,
Driving pump C not work, waling stripe is parallel with Y direction.
When the left surface of processing workpiece or right flank, control system controls to drive on the right side of pump A drive or the alignment pin in left side is flexible, drive pump B not work, and drives pump C to drive piston rod, waling stripe and top pad to push down the upper surface of workpiece from top.
When the leading flank of processing workpiece or trailing flank (or claiming two end faces), control system controls to drive on the right side of pump B drive or the side pressure pin in left side is flexible, drive pump A not work, and drives pump C to drive piston rod, waling stripe and top pad to push down the upper surface of workpiece from top.
Separately can be furnished with display screen or touch screen, it is possible to show the duty of several driving pump and input control instruction to control system.
If the rotatable platform for numerical control selected by workbench, four axles can be expanded as and control location, it is achieved multi-work piece more multiaspect or the processing of more direction.
Ram uses double compensating cylinder balanced controls, SCBS automatic compensation balance system balancing main spindle box weight, it is ensured that the stationarity of main spindle box motion.
Crossbeam uses large-sized Cross section Design, crossbeam leaves ram and moves the guide rail of required X-direction, and guide rail cross section is in the X-axis direction in stepped construction, and function alleviates the weight of crossbeam, can guarantee that again the height that ram moves is varied from.
XYZ tri-spindle guide is to the form that is connected all preferably employing import high precision overloading roller guide and great lead ball lead screw pair.Ensure processing high speed, in high precision, high rigidity and high stability.
