640 GLEASON “CNC” HYPOID SPIRAL BEVEL GEAR GENERATING MACHINE

MODEL NO. 640 GLEASON “CNC” HYPOID SPIRAL BEVEL GEAR GENERATING MACHINE SERIAL NO. 821301 ( NEW IN 1988 ) SUITABLE FOR THE COMPLETING OF LARGE SPIRAL BEVEL, ZEROL® BEVEL OR HYPOID PINIONS AND MATING GEARS UP TO 34” (863MM) DIAMETER OF ANY RATIO UP TO 10:1. WITH 1.08 DP (MODULE 23.5) CUTTING CAPABILITY. THE EXTREME VERSATILITY OF THIS MACHINE PERMITS THE GEAR MANUFACTURER TO SELECT THE MOST EFFICIENT CUTTING METHOD FOR ANY LOT SIZE OF GEARS IN HEAVY DUTY APPLICATIONS, SUCH AS TRUCKS, BUSES, TRACTORS, INDUSTRIAL MACHINERY, OFF-ROAD EQUIPMENT, AND MARINE DRIVES. THE 640 GLEASON MACHINE CAN COMPLETE ANY SPIRAL BEVEL GEAR OR PINION WITHIN THE MACHINE RANGE IN ONE 360 DEGREE REVOLUTION OF THE BLANK. THIS REQUIRES ONLY ONE SETUP, ONE CHUCKING, AND ONE CUTTER TO PRODUCE A PART. IN ADDITION TO COMPLETING, THE MACHINE USES RSR ® CUTTERS, AND ALL OTHER GLEASON CUTTING METHODS. FORMATE ® GEAR MEMBERS CAN BE CUT, AND MATING PINIONS GENERATED TO MATCH THEM. FEATURES 1 - THE VARIETY OF METHODS EMPLOYED BY THE 640-SERIES GENERATOR ENABLE THE MACHINE TO CUT THE FOLLOWING TYPES OF SPIRAL BEVEL GEAR SETS: COMPLETE GENERATED GEARS ROUGH GENERATED GEARS SINGLE ROLL ROUGH PINIONS OF GENERATED OR FORMATE PAIRS FINISH GENERATED GEARS ROUGH AND FINISH FIRST SIDE OF PINIONS OF GENERATED OR FORMATE PAIRS USING ANY SINGLE SIDE MODIFIED ROLL METHOD FINISH PINIONS OF GENERATED OR FORMATE PAIRS USING ANY SINGLE-SIDE MODIFIED ROLL TYPE DEVELOPMENT METHOD COMPLETE FORMATE PAIRS ROUGH FORMATE GEARS FINISH FORMATE GEARS (NOT SINGLE CYCLE) 2 - FULLY AUTOMATIC CYCLES SELECTABLE FOR THE FOLLOWING FUNCTIONS AND/OR FEATURES, INDIVIDUALLY OR IN COMBINATION: VARIABLE PLUNGE FEED SLIDING BASE SET-IN CRADLE ROTATIONAL SET-OVER NO ROLL CYCLE FOR FORMATE GEARS VARIABLE RATE OF ROLL DOUBLE ROLL DUAL ROTATION FOR GENERATED OR FORMATE GEARS MODIFIED ROLL VARIABLE SPEED CUTTER DRIVE ROLL CENTERING 3 - THE “DUAL ROTATION” FEATURE FOR EITHER “GENERATED” OR FOR “FORMATE” GEARS PROVIDES THE CYCLE WHERE EACH TOOTH-SPACE IN THE PART IS CUT TWICE, ONCE DURING EACH OF TWO ROTATIONS OF THE WORK-PIECE. THE “DUAL ROTATION” IS USED TO IMPROVE OVERALL SURFACE FINISH AND GENERAL PART QUALITY CNC CONTROL ALLEN BRADLEY 8600 “CNC” CONTROL FOR CUTTER-SPINDLE, CRADLE-ROLL, AND SLIDING-BASE FOR WORK-SPINDLE, WITH “ELECTRONIC GEAR BOX” (EGB) FOR CONTROL OF WORK-SPINDLE INDEXING, WITH SIMPLIFIED ENTRY OF “GLEASON CUTTING SUMMARY” DATA, AND MEMORY STORAGE CAPACITY FOR A MAGNITUDE OF DIFFERENT PART NUMBERS. ALPHANUMERIC KEYBOARD WITH NUMERICALLY CONTROLLED SPECIFIC FUNCTION KEYS OF THE TRADITIONAL TYPE, CONSOLE WITH PUSH-BUTTONS FOR SWITCH-ON, SWITCH-OFF, CYCLE START, HOLD, OPERATING MODE, AND MANUAL MOTION SPEED DIRECTION SELECTORS AND POTENTIOMETER FOR FEED RATE AND SPINDLE ROTATION VARIATION 12” CRT ALPHANUMERIC AND GRAPHIC KEYBOARD CNC CONTROL PROVIDES COMPLETE FLEXIBILITY WHEN CHANGING FROM ONE JOB TO ANOTHER, OR WHEN CHANGING MACHINE SETTINGS, (WITHOUT THE NEED OF CHANGE GEARS). CNC CONTROL PROVIDES EASIER REALIZATION OF THE “OPTIMUM CUTTING CONDITION” RESULTING IN FASTER PRODUCTION RATES. DEPENDING ON THE DIAMETER OF THE PART BEING CUT, CYCLE TIMES CAN BE AS SHORT AS 7 SECONDS PER TOOTH, INCLUDING CUTTING, INDEX AND RETURN ROLL OF THE CRADLE. ADDITIONAL FEATURES DOUBLE-ACTING HYDRAULIC CHUCKING SYSTEM PROVIDING UNIFORM, TORQUE-FREE CHUCKING LOAD. HYDRAULIC POWER UNIT W/ 3-HP MOTOR AND PUMP PROVIDING 7.5 GPM VOLUME AT 600 PSI, MONITORED BY PRESSURE SWITCH GAUGE POWER FORCED LUBRICATION SYSTEM WITH 6 GPM VOLUME AT 6-PSI DRIVEN BY SAME 3-HP MOTOR AS HYDRAULIC UNIT STOCK DIVIDING GAUGE FULL MACHINE ENCLOSURE WITH SAFETY INTERLOCK FOR GUARD DOORS COMPLETE COOLANT PLANT W/5-HP MAIN ELECTRIC MOTOR WITH 190 GALLON (720 LITERS) RESERVOIR CAPACITY, W/SIGHT-GLASS FOR MONITORING level AUGER-TYPE CHIP CONVEYOR AND MAGNETIC CHIP SEPARATOR FREE-STANDING ELECTRICAL SWITCH-GEAR CABINET W/FULL COMPLEMENT OF ELECTRICS (MOTORS/CONTROLS) * THIS RADIAL SETTING CAN BE INCREASED TO 18.5” (462.50MM) FOR SOME APPLICATIONS *** MAXIMUM OFFSET APPLIES TO PINION AND GEARS UP TO 25” O.D.
