CNC lathe Back Feeding for Shaft Parts

CNC lathe Back Feeding for Shaft Parts
CNC lathe with axial division,CNC lathe with feeding device supplier
Q series-precise linear guide-way with flat bed in blade row : Q5，Q7，Q5C，Q7C 
Q5 ,Q7, with the features of high precision. high speed. high efficiency, is the ideal selection for substituting hard rail lathes and imported lathes.
* High precision : importing components from Japan and Taiwan through the advanced assembly and inspection technology, realizing the  precise turning with tolerance of  μ level.
* High speed : more than 5000RPM for spindle ,rapid traverse 20m/s, to reach the high speed machining. 
*High-efficiency : with the concept of technique innovation and application oriented, and sustainability improve the overall performance, to make the processing more efficiency.
* Stability : high quality requirement  and strict selecting for all the components, to make the machine performance more stable.
Q5C,Q7C, (Synchronous electric spindle)- the best selection for substituting the imported lathes.
* More precision: the complete Synchronous servo configuration for the spindle and the X/Z axis, makes the processing accuracy get a new break through.
* Higher speed: the superior Synchronous electric spindle make the spindle perform higher, faster, and more stable.
* More efficiency: the complete, Synchronous control for the core parts (all the axis),makes the processing efficiency better.
In this technical solution,we use customized back feeding device to combine the precise Q series CNC lathe to realize the processing of  relatively long  shafts or such kind of  work pieces.
