CNC Turning Center with 2 Spindles, 2 Turrets and 1 Y-axis SlideMiyano Evolution LineBNJ
What could not be donecan be doneX-axis movement is added to the traditional self loading mechanism which the main spindle is fixedand the opposed sub spindle can move to the Z-axis direction to receive the workpiece.Wide space appears immediately after the back working turret is indexed at the concave position,then sub spindle passes.The state-of-art technology of starting full capacity machining immediately after turret indexcompletion reduces idle time and make it possible to do complete machining including eccentricmachining and multiple machining, which other machines cannot do.
Simultaneous machiningby main and back-workingturretsSimultaneous machining of work pieces on theL-spindle with the main turret and work on theR-spindle with the back working turret is the keyto high efficiency.Simultaneous, overlappingmachining for the front andback operationsOverlapping control, which enables the R-spindleto precisely follow the movement of the mainturret, reduces machining time for operationssuch as turning operation and combinedmachining with the Double sided revolving tool.Off-center machining on theR-spindleThe off-center collet on the R-spindle enablesoff-center machining including combinedmachining such as crank machining which othermachines are not capable of.Combined machining on theY-axisThe Y-axis function of the main turret enablesside milling which previously required bothC-axis and end milling. This also enables largediameter threading and machining of workpieces with large pockets and bosses whichwere previously difficult to machine.
Machining at full capacity starts immediately afterindexing the back working turret and the entireoperation is completed in a single process as a result ofcombined machining.Cranks and off-center bushes can also be machined.Machining at full capacity starts immediately after indexing the back working turretThe backworking turret has two concave sections.gain access to rearward facing tools mounted on theImmediately after this turret is indexed to a concavemain turret and/or to collect the workpiece from the Lsection, clearance is created to allow the R spindle tospindle.

A wide variety of combined machining with revolving tools Basic combined machining Large Diameter Helical Threading Milling of large pockets and bosses(Option)In addition to conventional crossdrilling, tapping and face tapping onthe main spindle's center axis, a Y-axisallows for off-center drilling, tapping,and milling.Linear and circular interpolation makes itpossible to machine large OD pockets andbosses on the Y-Z plane.Planetary tapZEndmillEndmillingZZYYXYXX Contour Milling Contouring milling Off-center machining High precision millingCombining the C-, X-, and Z-axesmakes it possible to do contour millingwith simultaneous 3-axis control.One side is machined off-center by contour milling andthe other side is machined off-center on the off-centerchuck. Double off-center machining can be performedon the machine.Accurate positioning by the C-axis and highprecision combined machining by the Y-axisallow for a wider range of machining.EndmillingOD cutting toolZZEndmillingZYXXXOff-centerThe L/R-spindles and tool spindles enable stable machiningDouble row roller bearing and angular L-spindle R-spindleSpindle headstockcontact ball bearing used for the frontSpindle quillbearing and double row roller bearing usedSpindlefor the back bearing are mounted in theStationarycollet chuckStationarycollet chuckquill housing for both L and R axes.
