MIYANO BND-34S3L CNC Turning Center with Bar Feeder
FOR SALE IS A MIYANO BND-34S3L LIVE TOOLING LATHE WITH A BAR FEEDER.
THIS LATHE AND BAR FEEDER ARE FULLY FUNCTIONAL AND WORKING; A VERY RELIABLE MACHINE.
THE TOOL TURRET HAS EIGHT TOOL PLACES, BUT SOME OF THE TOOL HOLDERS HOLD TWO TOOLS NEXT TO EACH OTHER, SO EACH TOOL PLACE HAS ACTUALLY 3 OFFSETS. FOR INSTANCE, TOOL #1 CAN BE CALLED BY T0101, T0909, OR T1717. ALL THREE CODES CALL THE SAME TURRET POSITION, BUT TO A DIFFERENT TOOL OFFSET (SEE THE SHORT VIDEO WITH THE PICS). THIS MAKES THE MACHINE ABLE TO HOLD MORE THAN JUST 8 TOOLS.
IN ADDITION, TURRET POSITIONS 2, 4, 6, & 8 ALL HAVE LIVE TOOLING CAPABILITIES IF ONE DESIRES TO PUT IN A LIVE TOOLING HOLDER, SUCH AS A RADIAL DRILL. THIS MACHINE COMES WITH TWO LIVE TOOLING HOLDERS. ONE THAT IS DIRECTLY RADIAL, AND ONE THAT IS AXIAL (AT A RIGHT ANGLE, TO DO FACE SLOTTING, OR OFF-CENTER DRILLING.
THE LIVE TOOLING SPINDLE POSITIONS CAN STOP ONLY AT INCREMENTS OF 5 DEGREES.
THE MANUAL ALSO COMES WITH THE MACHINE, AND A WIDE RANGE OF HARDINGE 22D COLLETS, WHICH IS WHAT THE MAIN SPINDLE TAKES. THE MAX DIAMETER FOR THE 22D COLLET SYSTEM IS 1.625″.
THE SUB-SPINDLE TAKES TRAUB 32 COLLET TYPE. NOT SURE WHY THEY ARE DIFFERENT, BUT THEY ARE.
THE PART CATCHER WORKS GREAT AND THE PART CONVEYOR WORKS TO MOVE THE PART OUTSIDE THE MACHINE INTO A BIN.
THE CHIP CONVEYOR ALSO WORKS.
THE BAR FEEDER IS A SIMPLE AUTOMATIC BAR FEEDER AND WORKS WELL. IT HOLDS 12′ BARS.
THE SUB-SPINDLE DOES WORK, HOWEVER, THE PART EJECTOR IS MISSING, AND I AM NOT SURE IF IT WORKS. AS IT IS, THIS MACHINE IS IDEAL FOR A 1ST OP BAR FEED ON A CONTINUOUS CYCLE.
THIS MACHINE DOES NEED SOME MAINTENANCE. THE HYDRAULIC LINES HAVE SLOW LEAKS AND THESE SHOULD BE REPLACED. THE HYDRAULIC OIL NEEDS TO BE TOPPED OFF EVERY FEW DAYS WITH CONTINUOUS USE.
THE Z AXIS HAS ABOUT .014″ BACKLASH. THIS NEEDS TO BE TAKEN INTO ACCOUNT, BUT CAN BE PROGRAMMED AROUND.
THE X-AXIS HAS ABOUT .002″ BACKLASH.
THIS MACHINE IS SOLD AS IS.
IT IS THE BUYER’S RESPONSIBILITY TO PICK UP AND MOVE THIS MACHINE.
