 CAPABILITIES

  • THE TF-9DHD IS AN AUTOMATIC INFEED/THRUFEED CENTERLESS GRINDER. SMALL IN FOOTPRINT, VERY CAPABLE GRINDER. UTILIZING UP TO AN 8-5/8” (219MM) WIDE WORK WHEEL, IT IS ABLE TO REMOVE MORE MATERIAL, FASTER AND WITH BETTER SURFACE FINISHES THAN SIMILAR MACHINES WITH NARROWER GRINDING WHEELS. THIS MACHINE IS SUPERIOR TO COMPETING MACHINES IN THE SAME CLASS DUE TO THE FACT THAT IT CAN RUN A 15HP MAIN SPINDLE MOTOR IN SUCH A SMALL PACKAGE. THIS MEANS MORE MATERIAL CAN BE REMOVED PER PASS THAN LARGER MACHINES. THE HARD CHROME PLATED CAST IRON SLIDES ARE DOVETAIL GROUND TO PROVIDE SUPERIOR RIGIDITY WHEN POSITIONING THE REGULATING WHEEL. BOTH TOP AND BOTTOM SLIDES CAN BE POSITIONED INDEPENDENTLY REDUCING SETUP TIMES DRAMATICALLY.
  • INCLUDES PRECISION BEARINGS ON THE WORK HEAD ASSEMBLY AS WELL AS 0.1 MICRON GLASS SCALE FEEDBACK FOR CLOSED LOOP POSITION CONTROL. A SIMPLE TOUCH SCREEN CAN BE TAILORED TO ADDRESS YOUR PROCESS. WE FULLY CUSTOMIZE THE INTERFACE TO ADAPT TO INSTALLED INSPECTION SYSTEMS, AUTOMATION WITH THE SOLE PURPOSE OF MAKING THE MACHINE SIMPLE TO OPERATE.
  • ANOTHER TIME SAVING FEATURE IS THE WORK REST BLADE HEIGHT ADJUSTMENT. IN ADDITION TO BEING AN INDEPENDENTLY CONTROLLED AXIS RELATIVE TO THE WORK WHEEL, THE WORK REST BLADE HEIGHT CAN BE ADJUSTED SIMPLY USING ONE SCREW. A BUILT IN RAMP ACCOMPLISHES THIS UNIQUE FEATURE FURTHER REDUCING SETUP TIME.
  • THE TF-9DHD MACHINE CAN BE FITTED WITH A TEMPLATE TRACING WORK WHEEL AND REGULATING DRESSERS TO COVER THE 8.25″ WIDE FACE OF THE WHEEL. BOTH HYDRAULIC AND SERVO DRIVEN REGULATING WHEEL DRIVES CAN BE INSTALLED ON THIS MACHINE DEPENDING ON APPLICATION REQUIREMENTS.
  • AS A THRUFEED GRINDER, THE MACHINE CAN BE FITTED WITH ENTRANCE AND EXIT TRACKS TO GRIND BAR STOCK. IT IS COMMON TO FIND THIS MACHINE SETUP TO FINE GRIND WIRE TO +/-0.0001″ OVER 12 FEET OF WIRE.
  • IT IS NOT UNUSUAL TO INSTALL SEVERAL DIFFERENT GRIT WHEEL SEGMENTS OVER THE 8.25 INCH SPAN RANGING FOR ROUGH SEGMENTS TO FINER SEGMENTS FOR THE EXIT SIDE. THIS ALLOWS US TO REMOVE MORE MATERIAL IN A SINGLE PASS WHILE STILL MAINTAINING A SUPERIOR SURFACE FINISH ON THE EXIT SIDE OF THE MACHINE
  • INFEED GRINDING CAN BE PERFORMED ON THIS MACHINE TO PROCESS PINS AND SHOULDERED PARTS WHERE A PLUNGE IS REQUIRED. THE INFEED CYCLE CAN BE SIMPLY DEFINED ON THE THE TOUCH SCREEN CONTROL TO INSURE FLUID MOTION AS THE GRINDING WHEELS CONTACT. THIS ELIMINATES CHATTER AND HAS THE ABILITY TO CONTROL THE GROUND DIAMETER TO TIGHT TOLERANCES.
  • MEDICAL GUIDEWIRE GRINDING TO DIAMETERS DOWN TO 0.002″ FROM 0.023″ DIAMETER. GLEBAR HAS BEEN GRINDING MEDICAL GUIDEWIRES SINCE THE EARLY 1970’S INNOVATING OVER THE YEARS TO IMPROVE THE PROCESS AND ARM ENGINEERS WITH THE TOOLS TO IMAGINE DEVICES PREVIOUSLY IMPOSSIBLE TO MAKE.

 THE TF-9DHD CAN BE CONFIGURED TWO WAYS TO GRIND GUIDEWIRES :

  • IN A TRADITIONAL GRINDING METHOD A WIDE WHEEL DRESSED WITH THE SINGLE TAPER CAN BE SETUP. THE PRODUCT THU FEEDS INTO THE MACHINE TO A SET SENSOR POSITION ON A TRACK AT WHICH POINT, AN AUTOMATIC WIRE RETRACTOR RETRIEVES THE WIRE. THE RESULT IS A WIRE WITH ONE TAPER AND A BARREL.
  •  OPTIMIZED VACUUM FEEDING SYSTEMS CAN PRODUCE SHORT STYLETS AS FAST AS 5 SECONDS PIECE-TO-PIECE UNATTENDED USING THIS METHOD.
  • IN THE PROFILING CONFIGURATION, A NARROW 1.5″ OR 3″, GRINDING WHEEL IS DRESSED WITH A SHORT FUNNEL FORM. SENSORS DETERMINING THE START AND END OF A DESIRED TAPER ARE INSTALLED IN AN AUTOLOADER.
  • AS THE WIRE IS THRU FED INTO THE MACHINE, THE SENSORS INITIATE THE RETRACTION OF THE REGULATING WHEEL SLIDE PRODUCING THE DESIRED TAPER ON THE FLY. THE CONTROL IS ABLE TO VARY THE VELOCITY OF THIS RETRACTION TO INSURE CORRECT TAPER LENGTHS ARE ACHIEVED. MULTIPLE TAPERED GRINDS IN ONE PASS ARE POSSIBLE USING THIS UNIQUE METHOD.
  • UP TO SIX TAPERS OR COMPLEX CURVES CAN BE PRODUCED USING THIS METHOD BY DETECTING EITHER THE DISTAL OR PROXIMAL END OF THE WIRE.
  • BUILT-IN PADDLE GRINDING CYCLES CAN SIMPLY PRODUCE HEADS ON WIRES IN SOME CASES WITHOUT THE USE OF A MECHANICAL PADDLE STOP.
