HURCO FIELD SERVICE BULLETIN DATE: AUGUST 24, 1981 ISSUE NUMBER: SUBJECT: TOOL CHANGER ALIGNMENT PRODUCT LINE: MB1 1001 SUPERSEDES NUMBER: 102 PAGE 1 OF 7 NOTE: DURING TC SET-UP, ENSURE TORQUE LIMITER NUT IS FULLY LOOSE UNTIL ALL OTHER ADJUSTMENTS ARE MADE. THIS PREVENTS THE ARM FROM SWINGING. SHOT PIN ADJUSTMENT 1. 2. 3. 4. APPLY BLUEING TO LOWER SPINDLE COUPLING. ROTATE THE SPINDLE SO THE NOTCH IS NOT ALIGNED WITH THE SHOT PIN. ENERGIZE SHOT PIN MANUALLY, AND ROTATE SPINDLE. THE SHOT PIN SHOULD CONTACT LOWER SPINDLE COUPLING EVENLY. IF NOT, ADJUST SHOT PIN BRACKET AND REPEAT PROCEDURE. SHOT PIN LIMIT SWITCH ADJUSTMENT 1. INSTALL THE LIMIT SWITCH MOUNTING BRACKET USING LOCKTITE 242 ON THE B.H.C.S. NOTE: PLACE A TIE WRAP AROUND THE LIMIT SWITCH TO HOLD THE PLASTIC IN PLACE. 2. ROTATE THE SPINDLE UNTIL IT'S NOTCH IS DIRECTLY IN FRONT OF THE SHOT PIN CYLINDER. 3. ENERGIZE THE SHOT PIN MANUALLY (VALVE IN UPPER RIGHT SIDE OF SPINDLE HEAD CASTING). 4. WATCH FOR LIMIT SWITCH TO BE ACTUATED WHEN THE SHOT PIN IS ENERGIZED. 5. ORIENT THE SPINDLE TO THE POSITION WHERE THE SHOT PIN NOTCH IS NOT IN FRONT OF THE SHOT PIN. 6. ENERGIZE THE SHOT PIN. MAKE SURE THE SWITCH IS NOT ACTUATED, IF IT DOES, ADJUST THE LIMIT SWITCH, THEN REPEAT STEPS 3 AND 4. NO TOOL IN SPINDLE P.C. BRD MOUNTING AND ADJUSTMENT 1. ENSURE THE P.C. BOARD IS CORRECTLY COATED WITH HUMISEAL (BOTH SIDES. 2. INSTALL THE BOARD IN HEAD, USING B.H.C.S & LOCKTITE #242. 3. WATCH OPTICAL SWITCH WHILE ALTERNATING CLAMPING AND UNCLAMPING ENSURE THAT OPTICAL SWITCH DOES NOT RUB ON THE RING. 4. FINAL ADJUSTMENT IS MAKE AFTER THE OTHER LIMIT SWITCH ADJUSTMENTS ARE COMPLETE. ORIGINATOR: REVISED BY: WAYNE E. HAWKINS R. BRYANT

TC ARM SET UP 1. POSITION A PIECE OF WOOD PERPENDICULAR TO THE LEFT END OF THE TABLE. SET A SMALL HYDRAULIC JACK ON THE WOOD AND PLACE A BLOCK OF WOOD ON TOP OF THE JACK. RAISE JACK TO SUPPORT TC ASSEMBLY. 2. LOOSEN FOUR M12 S.H.C.S ADJUST JACK UNTIL TC ASSEMBLY IS LEVEL. POSITION LEVEL ON ARM WHEN ARM IS HALFWAY BETWEEN FULLY RETRACTED AND FULLY FORWARD. TIGHTEN SCREWS, REMOVE THE JACK, AND CHECK ARM AT FULLY RETRACTED, HALFWAY AND NEAR SPINDLE. THE ARM SHOULD NOT SWING BY ITSELF IN EITHER DIRECTION UPON RELEASE. 3. MOVE TC ARM UNDER SPINDLE AND RECHECK LEVEL. 4. MOVE ARM BACK, REMOVE SHOCK ABSORBER AND SCREW MECHANICAL STOP INTO ARM. 5. INSERT TOOL HOLDER IN SPINDLE. JOG Z-AXIS TO ALLOW THE TOOL CHANGER FINGERS TO ENGAGE THE TOOL HOLDER. DEPRESS THE EMERGENCY STOP. USING A TAPE MEASURE, MEASURE FROM THE LOWER SURFACE AT Z BALLNUT TO MATING AXIS STOP SURFACE. MB-1 MILLS REQUIRE 13.75". IF SLIGHTLY LESS, 13.6" OR GREATER, RAISE ARM FROM LEVEL POSITION A SMALL AMOUNT. RECHECK. 6. DEPRESS POWER ON TO RELEASE BRAKE. WHILE ACTIVATING SHOT PIN SOLENOID, ROTATE SPINDLE UNTIL SHOT PIN ENGAGES, DEPRESS EMERGENCY STOP. (THIS PROCEDURE WILL ALIGN THE TOOL HOLDER FOR A TOOL CHANGE ORIENTATION. 7. ENSURE THE GENEVA DRIVE ACTIVATES THE LIMIT SWITCH IN THE TOOL CAROUSEL THROUGHOUT THIS ADJUSTMENT PERIOD. POSITION TC ARM UNDER THE SPINDLE TO CHECK THE ALIGNMENT OF TC FINGER TO TOOL HOLD V SLOT. LOOK FOR DEFLECTION OF EACH FINGER. IF MISALIGNED, ADJUST FOUR M10 JACK SCREWS ON TC MOUNDING BRACKET SCREWS AND TIGHTENING M12A. BY ADJUSTING A SMALL AMOUNT AT A TIME, THE CORRECT ADJUSTMENT CAN BE DETERMINED. WHEN THE GENEVA DRIVE HAS EQUAL CW AND CCW MOTION, THE ARM IS CORRECTLY ADJUSTED. (ROTATING THE GENEVA DRIVE BY HAND WILL FORCE THE CAROUSEL TO ROTATE SLIGHTLY CW AND CCW UNTIL THE TOOL FINGERS TOUCH AGAINST IT'S NEIGHBORING FINGER. THE PHYSICAL AMOUNT OF GENEVA CW AND CCW MOTION SHOULD BE EQUAL FOR CENTER ADJUSTMENT.) 8. THE "CAROUSEL IN POSITION SWITCH-SHOULD BE ADJUSTED INTO ], (AND AS CLOSE AS POSSIBLE TO) THE GENEVA DRIVE TO ENSURE THE DRIVE STOPS ON THE FLAT READER PORTION. THIS SWITCH NOT ONLY ALLOWS TOOL POSITION TO BE READ, BUT MOST IMPORTANTLY COMMANDS THE TOOL CAROUSEL ROTATE MOTOR TO STOP ROTATING. THERE IS A SLIGHT MOTOR COASTING, SO THE SOONER THE SWITCH IS MADE THE SOONER THE MOTOR WILL STOP. (THE COASTING SHOULD LEAVE THE GENEVA DRIVE "FLAT" ON THE CENTER OF THE SWITCH. 9. WHEN ADJUSTMENTS ARE COMPLETE, USE LOCTITE # 242 ON ALL MOUNTING SCREWS. BY REMOVING AND LOCTITING ONE SCREW AT A TIME, THE ADJUSTMENTS WILL HOLD POSITION. TC ENCODER P.C. BOARD ADJUSTMENT 1. POWER ON TO RELEASE THE BRAKE. INSERT TOOL HOLDER IN SPINDLE, ACTIVATE THE SHOT PIN AND ROTATE THE SPINDLE UNTIL THE SHOT PIN ENGAGES THE NOTCH. 2. ROTATE CAROUSEL UNTIL TOOL #9 LINES UP WITH THE TOOL HOLDER IN THE SPINDLE. 3. DEPRESS THE EMERGENCY STOP. 4. POSITION ARM SO FINGERS ENGAGE THE TOOL HOLDER. NOTE: ENSURE THE GENEVA DRIVE ACTUATES THE LIMIT SWITCH. 5. THE NUMBER 9 SHOULD APPEAR ON THE CRT BESIDE COORDINATES. 6. IF NOT, ADJUST TC ENCODER BY LOOSENING THE BRACKET AND EITHER TURNING OR RAISING/LOWERING UNTIL #9 IS DISPLAYED. BY ROTATING THE PC BRD, THE # 8 WILL APPEAR IN ONE DIRECTION, AND #1 IN THE OTHER. ADJUST THE BOARD TO THE CENTER OF THIS BAND.

7. WHILE FINGERS ENGAGE THE TOOL HOLDER, GENTLY ROTATE GEAR IN BOTH DIRECTIONS TO THE PHYSICAL LIMIT. DEPRESS THE LIMIT SWITCH AT EACH LIMIT AND ENSURE #9 STILL APPEARS ON THE SCREEN. ID NOT, FINE ADJUST THE ENCODER BOARD. 8. MOVE THE ARM AWAY FROM THE TOOL. ROTATE GENEVA GEAR BY HAND TO ENSURE THE ENCODER BOARD PHOTO EYES DO NOT RUB ON THE ENCODER RINGS. 9. POWER ON, DEPRESS CHECK, OPERATE, ROTATE, AND WATCH THE SCREEN FOR EACH CORRECT TOOL NUMBER. 10. IF NO TOOL NUMBER IS DISPLAYED AS THE CAROUSEL MOVES INTO POSITION, THEN ADJUST TOOL CAROUSEL IN-POSITION LIMIT SWITCH. NOTE: IT MAY BE NECESSARY TO ADJUST THE TC ENCODER BOARD FOR ALL TOOL NUMBERS TO BE DISPLAYED. 11. IF THE WRONG TOOL NUMBER IS DISPLAYED, FINELY ADJUST THE TOOL CHANGER ENCODER BOARD. 12. USE LOCTITE #242 ON ALL MOUNTING SCREWS, REMOVING THEM ONE AT A TIME. MECHANICAL STOP ADJUSTMENT 1. POWER ON TO RELEASE THE BRAKE. INSERT TOOL HOLDER IN THE SPINDLE. ACTIVATE SHOT PIN AND ROTATE THE SPINDLE UNTIL SHOT PIN ENGAGES NOTCH. RELEASE THE SHOT PIN WITHOUT ROTATING THE SPINDLE. 2. DEPRESS THE EMERGENCY STOP. LOOSEN TORQUE LIMITER NUT. 3. MOVE ARM UNTIL FINGERS FULLY ENGAGE THE TOOL HOLDER. 4. ADJUST MECHANICAL STOP TO JUST "TOUCH OFF" THE STOP BLOCK. 5. TIGHTEN LOCKNUT (8mm) USING LOCTITE # 242. SHOCK ABSORBER INSTALLATION 1. INSTALL THE SHOCK ABSORBER IN THE ARM, SCREWING IN UNTIL BODY IS EVEN WITH THE ARM SURFACE. NOTE: DO NOT TIGHTEN LOCKNUT AT THIS TIME. 2. FINAL ADJUSTMENT WILL BE MADE IN LATER STEPS. TC HEIGHT ADJUSTMENT 1. DEPRESS POWER ON, CHECK OPERATE, TOOL CAL. 2. BRING THE HEAD DOWN WITH THE TOOL HOLDER CLAMPED IN THE SPINDLE TO PROPER ALIGNMENT WITH THE T/C FINGERS. (WHEN THE CAROUSEL IS MOVED INTO CONTACT WITH THE TOOL HOLDER). OBSERVE CAREFULLY THAT THE FINGERS ENGAGE THE "V" FLANGE OF THE HOLDER CENTRALLY UP AND DOWN AND RADIAL SO BOTH FINGERS OPEN APPROXIMATELY EQUALLY. 3. MOVE THE CAROUSEL BACK OUT OF THE WAY. IN DATE BLOCK "0", TOOL CALIBRATE, MOVE THE HEAD UP 2.4 INCHES. ADJUST THE ENCODER DISK ROTATION SO THE MARKER IS NOW ALIGNED AT THIS POINT. 4. YOU SHOULD NOW HAVE THE HEAD APPROXIMATELY .100 INCHES BELOW TOP LIMIT SWITCH SETTING. THIS .100 INCH MAY VARY AS THE T/C POSITION IS DETERMINED FROM THE FIRST MARKER PULSE/ ADJUST THE TOP LIMIT SWITCH UP OR DOWN AS NECESSARY TO STAY IN THE RANGE OF .075 TO .125. 5. USE LOCTITE #242 ON ALL MOUNTING SCREWS. 6. CHECK FOR Z TRAVEL (-16.050" TO -16.150". EMERGENCY STOP ARM DEFLECTION LIMIT SWITCH ADJUSTMENT. 1. MOUNT VEE BLOCK. POWER ON TO RELEASE THE BRAKE. INSERT TOOL HOLDER IN THE SPINDLE. ACTIVATE THE SHOT PIN AND ROTATE THE SPINDLE UNTIL SHOT PIN ENGAGES THE NOTCH. 2. DEPRESS THE EMERGENCY STOP. LOOSEN THE TORQUE LIMITER NUT. 3. MOVE THE ARM IN, UNTIL FINGERS ENGAGE THE TOOL HOLDER.

4. THIS STEP IS VERY IMPORTANT! ADJUST THE VEE BLOCK SO ANY ARM MOVEMENT INTERRUPTS THE SWITCH. 5. TEST ADJUSTMENT BY PERFORMING 10 TOOL CHANGES WITH NO TOOLS IN THE CAROUSEL. (NO TOOLS WILL ALLOW THE ARM TO FORWARD WITH MAXIMUM FORCE. IN SHOULD NOT TRIP SWITCH,) 6. USE LOCTITE #242 ON ALL MOUNTING SCREWS. ARM FORWARD LIMIT SWITCH ADJUSTMENT 1. POWER ON TO RELEASE THE BRAKE. INSERT TOOL HOLDER IN THE SPINDLE. ACTIVATE THE SHOT PIN AND ROTATE THE SPINDLE UNTIL THE PIN ENGAGES THE NOTCH. 2. DEPRESS THE EMERGENCY STOP. LOOSEN THE TORQUE LIMITED NUT. 3. MOVE THE ARM IN, UNTIL FINGERS FULLY ENGAGE THE TOOL HOLDER. 4. ADJUST ARM FORWARD SWITCH SO IT HAS JUST BEEN ACTIVATED. SWITCH SHOULD ACTIVATE SLIGHTLY BEFORE DESIRED FORWARD POSITION TO KEEP ARM FROM BANGING AT STOP. 5. USE LOCTITE # 242 ON SET SCREWS. ARM RETRACT 1. THE ARM RETRACT SWITCH IS ADJUSTED SO THE "COASTING" ACTION LEAVES THE ARM IN A SAFETY-RELATED POSITION, ALLOWING CLEARANCE FROM THE TC CARROUSEL TO THE HEAD OF THE MILL AND FROM THE CONDUIT TO CHAIN. (THERE IS NO MECHANICAL STOP IN THE RETRACT POSITION.) 2. USE LOCTITE # 242 ON SET SCREWS. CHAIN ADJUSTMENT 1. ADJUST CHAIN BY MOVING THE MOTOR BRACKET BACKWARDS OR FORWARD ON ITS SLOTS. 2. SLACK SHOULD BE TAKEN OUT, BUT THERE SHOULD BE NO PRESSURE APPLIED THROUGH CHAIN. THE DRIVE PACKAGE SHOULD BE HORIZONTAL, NOT AT AN ANGLE. 3. USE LOCTITE #242 ON ALL MOUNTING SCREWS AND SET SCREWS. TORQUE LIMITER ADJUSTMENT 1. MATE-IN THE TORQUE LIMITER BY TIGHTENING TO APPROXIMATELY FINAL TIGHTNESS, THEN ADDITIONAL 1/8 TURN. REQUEST TC WHILE HOLDING ARM STATIONARY. ALLOW THE LIMITER TO SPIN FOR 60 SECONDS. LOOSEN AND PROCEED. 2. USE A SMALL AMOUNT OF GREASE BETWEEN THE NUT AND LOCK WASHER TO PREVENT DAMAGE TO THE LOCK WASHER. 3. TIGHTEN THE NUT UNTIL THE ARM MOVEMENT BECOMES STIFF BY HAND. 4. DURING AN AUTOMATIC TOOL CHANGE, THE CLUTCH SHOULD SLIP APPROXIMATELY 1/4 TURN WHEN THE TOOL IS AT SPINDLE. 5. BEND TAB ON THE LOCK WASHER FULLY INTO GROOVE IN THE NUT TO PREVENT THE NUT FROM LOOSENING. DRY RUN THE CT WITH NO TOOL HOLDERS. SHOCK ADJUSTMENT 1. ADJUST SHOCK ABSORBER SO THE ARM HAS A SMALL AMOUNT OF "SLOW DOWN" WHEN TC FINGER ENGAGE THE TOOL HOLDER. BANGING NOISE SHOULD NOT OCCUR. AS MUCH OF THE SHOCK TRAVEL AS POSSIBLE SHOULD BE USED (APPROXIMATELY 3/4 " TO 7/8".) 2. TIGHTEN LOCKING NUT.

TOOL IN CAROUSEL LIMIT SWITCH NOTE: ENSURE ACTUATORS ARE LUBRICATED WITH OIL OR GREASE. 1. PLACE A TOOL IN EACH POSITION IN THE TOOL CAROUSEL. 2. ROTATE CAROUSEL AND STOP AT EACH POSITION. 3. ENSURE TOOL IN-CAROUSEL SWITCH IS ACTUATED AND THAT THE LIMIT SWITCH IS NOT ACTUATED WHEN THE TOOL IS REMOVED. NO TOOL IN-SPINDLE LIMIT SWITCH ADJUSTMENT WARNING: PLACE YOUR HAND NEAR THE EMERGENCY STOP BUTTON. 1. INSTALL TOOL HOLDER IN SPINDLE AND TOOL IN #1 SLOT IN CAROUSEL. IN DATA BLOCK 0, PROGRAM CUR TOOL 0 AND ATTEMPT TOOL CHANGE. CRT SHOULD READ ES TC ERROR. 2. OPTICAL SWITCH SHOULD BE MADE WITH NO TOOL IN SPINDLE AND NOT MADE WITH THE TOOL IN THE SPINDLE. ADJUST ACCORDINGLY. THE OPTIC SWITCH SHOULD NOT RUB THE ENCODER RING. 3. USE LOCTITE #242 ON THE MOUNTING SCREWS. FINE ADJUSTMENTS MAY BE REQUIRED THROUGHOUT TC, AS THE FIRST FEW AUTOMATIC TOOL CHANGES ARE MADE. HINT: ADJUSTING IN SMALL INCREMENTS AIDS IN FIND TUNING. SPINDLE ORIENT RPM 1. THE ORIENT RPM SHOULD BE 1 REVOLUTION PER 2 SECOND PERIOD. 2. JOG Z AXIS BELOW TOOL CHANGE HEIGHT (-2.4"0. CHANGE TOOL "VIA" DATA BLOCKS "0" AND DEPRESS MOTION HOLD BEFORE -2.4" IS REACHED. THE SPINDLE WILL TURN AT ORIENT SPEED AND R40 ON THE ISOLATION INTERFACE BOARD CAN BE ADJUSTED FOR THE CORRECT RPM RESEAL R40. Z AXIS TOOL CHANGER CURRENT LIMIT ADJUSTMENT 1.

HURCO FIELD SERVICE BULLETIN DATE: JANUARY 5, 1982 ISSUE NUMBER: 1003 SUBJECT:NUISANCE SHEAR PINNING ON PARAJUST B SUPERSEDES NUMBER: 119 PRODUCT LINE: ALL B AND BX BED MILLS PAGE 1 OF 1 WE HAVE RECENTLY FOUND THAT NUISANCE SHEAR PINNING IS NOT CAUSED BY THE ACTUAL SHEAR PIN CIRCUITRY BUT IS CAUSED BY THE SHEAR PIN RESET CIRCUITRY. THIS CIRCUIT DRAWN BELOW IS COMPOSED OF NORMALLY CLOSED SET OF K1 CONTACTS, CAPACITOR C12 ON THE FREQUENCY CONTROL BOARD AND K5 RELAY ON THE VOLTAGE CONTROL BOARD. WHENEVER WE TURN THE DRIVE OFF WE DROP OUT THE K1 RELAY WHICH IN TURN CLOSES THE K1 CONTACTS ALLOWING CURRENT TO FLOW THROUGH THE K5 RELAY COIL. THE K5 WILL THEN PICK UP AND SHOULD STAY PICKED UP UNTIL CAPACITOR C12 CHARGES AT WHICH POINT K5 THEN DROPS OUT. THIS IS THE REASON WHY, WHENEVER WE DO A TOOL CHANGE, IT APPEARS THAT WE GET A SHEAR PIN INDICATION. IF WE DISABLE THE CIRCUIT BY CLIPPING CAPACITOR C12 OUT THE NUISANCE SHEAR PIN WILL GO AWAY. WE CAN ALSO ATTRIBUTE THE K5 STICKING RELAY PROBLEM TO THIS SAME CIRCUIT IF CAPACITOR C12 IS LEAKY IT MIGHT ALLOW ENOUGH CURRENT TO FLOW EVEN WHEN CHARGED TO HOLD THE K5 RELAY ON. THIS WOULD BE SEEN AS A STUCK RELAY AND TAPPING THE RELAY USUALLY DROPS IT OUT. IF YOU SHOULD RUN INTO THIS PROBLEM TRY CLIPPING C12 AND RUNNING THE MACHINE TO SEE IF THE PROBLEM GOES AWAY. IF IT DOES NOT GO AWAY WHEN IT IS AN ACTUAL SHEAR PIN AND SHOULD BE INVESTIGATED TO FIND THE CAUSE OF THE PROBLEM. ORIGINATOR: WAYNE HAWKINS REVISED BY:

What was the Stone Age? The Stone Age is the name given to the time in history which is the earliest period of very early humans using stone tools. The Stone Age ended when people began smelting metal leading into the Bronze Age. We also call the Stone Age 'prehistoric' which is a time before historical records were made and kept.
