STORAGE PROCEDURE

It is important to follow the procedures below when placing your grinding in storage for anextended period of time. Proper care will help maintain the working functions of the grinder anddecrease maintenance and problems that occur when storing the grinder.

BEFORE STORING THE GRINDER:

-Clean the machine thoroughly. (DO NOT USE COMPRESSED AIR OR A POWER WASHERTO CLEAN THIS MACHINE!) See Maintenance section for instructions on cleaningpolycarbonate.

-Lubricate the following parts by flooding the area with a spray lubricant and leaving it inplace: (Do not use a Teflon based lubricant)

Traverse Shafts & Linear bearings (see Lubrication section of manual)Remove grinding wheel and spray the movable parts of the finger systemCross slide shafts and adjustment screws (Right side of Traverse Base)Scratches in the paint or any other bare metal surfaces

-Work the lubricant in by moving parts through their full range of motion.

-Make sure all controls are in the off position and unplug the unit from the wall. Turn off the digitalalignment gage.

-Cover the unit if possible with a sheet or tarp.

BRINGING THE UNIT BACK INTO SERVICE:

-Remove the cover and reapply lubricant to the items stated above. Wipe off all excess lubricant. (See Lubrication section for more details.)

-Plug the unit into the wall and test all electrical functions.

-Check the belts for cracking and adjust the tension if necessary.

-Check for damaged or missing parts.

13

LUBRICATION

STEP 1--Thoroughly clean the shafts.

STEP 2--Flood spray the two shafts with a spray lubricant (do not use a teflon basedlubricant) until the lubricant is dripping off the shafts. See FIG. 10 Then run the carriageback and forth through its range of travel. This will carry the lubricant into the bearings.

STEP 3--With a clean rag, wipe off the excess amount of lubricant from the shafts. Run thecarriage back and forth through its range of travel and wipe the shafts after each traverse.Repeat until the shafts are dry to the feel. This completes the lubrication process.

If the unit will be shut down for an extended period of time, more than four weeks, then theshafts and other appropriate parts of the unit should be flooded with lubricant and thatlubricant left in place until the unit is brought back into service. When the unit is brought backinto service the full lubrication procedure as stated above should be repeated.

CLEANING AND MAINTENANCE GUIDELINES FOR POLYCARBONATEWINDOWS

Cleaning Instructions

DO NOT USE GASOLINEAdherence to regular and propercleaning procedures is recommendedto preserve appearance and performance.

Washing to Minimize ScratchingWash polycarbonate windows with a mild dish washing liquid detergent and lukewarm water, using a cleansoft sponge or a soft cloth. Rinse well with clean water. Dry thoroughly with a moist cellulose sponge toprevent water spots. Do not scrub or use brushes on these windows. Also, do not use butyl cellosolve indirect sunlight.Fresh paint splashes and grease can be removed easily before drying by rubbing lightly with a goodgrade of VM&P naphtha or isopropyl alcohol. Afterward, a warm final wash should be made, using a milddish washing liquid detergent solution and ending with a thorough rinsing with clean water.

Minimizing Hairline ScratchesScratches and minor abrasions can be minimized by using a mild automobile polish. Three suchproducts that tend to polish and fill scratches are Johnson paste Wax, Novus Plastic Polish #1 and #2,and Mirror Glaze plastic polish (M.G. M10). It is suggested that a test be made on a corner of thepolycarbonate window with the product selected following the polish manufacturer's instructions.

Some Important "DON'TS"♦ DO NOT use abrasive or highly alkaline cleaners on the polycarbonate windows.♦ Never scrape polycarbonate windows with squeegees, razor blades or other sharp

instruments.♦ Benzene, gasoline, acetone or carbon tetrachloride should NEVER be used on polycarbonate

windows.♦ DO NOT clean polycarbonate windows in hot sun or at elevated temperatures.

Graffiti Removal• Butyl cellosolve, (for removal of paints, marking pen inks, lipstick, etc.)• The use of masking tape, adhesive tape or lint removal tools works well for lifting off old

weathered paints.• To remove labels, stickers, etc., the use of kerosene, VM&P naphtha or petroleum spirits is

generally effective. When the solvent will not penetrate sticker material, apply heat (hairdryer) to soften the adhesive and promote removal.

GASOLINE SHOULD NOT BE USED!

MAINTENANCE (Continued)

DIGITAL GAGE

Important - Do not mark the scale unit with and electric engraver or

scratch the scale. - Always use an SR44 battery (silver oxide cell) - If the scale will not be used for more than three months,

remove the battery and store it properly. Otherwise,leakage, if any, from the battery may damage the unit.

Battery Installation and Origin SettingSet the origin of the scale after installing the battery. Otherwise,the error sign("E" at the least significant digit) may appear,resulting in incorrect measurements.1) To install the battery, remove the compartment lid and

install the SR44 battery with its positive side facing up.After the battery is installed, set the origin.

2) To set the origin, move the slider to an area you wish toset as your origin. Turn the power on. Hold the ORIGINswitch down for more than one second. The "0.00"display appears, indication Origin setting is complete. Theorigin will be retained even if the power is turned off.

Incremental (INC) & Absolute (ABS) modeThe LCD will dispay measurements from the origin when turnedon (ABS mode). To set the origin see above. The display can beset to zero at any desired position by pressing the ZERO/ABSswitch. INC indicator will apper in the display (INC mode),permitting measurements from this zero point. To return to theABS mode hold the ZERO/ABS buttton form more than2 seconds.

Error Symptoms & Remedies - ERRC and display flickering: Occurs when the scale

surface is stained. Clean the scale surface and coat athin film of low viscosity oil to keep out moisture.

- E in the least significant digit: This occurs when theslider is moved too quickly, but it does not affect themeasurement. If it stays on when the slider stops, thescale surface is probably stained. If this is the case, takeremedies as for ErrC.

- B indication: Battery voltage is low. Replace the batteryas soon as possible.

ADJUSTMENTS

STEP 1--Detach the bellows mounting brackets from thecarriage. Detach front and rear shields. See FIG. 15.STEP 2--Remove the three screws of one linear bearingand slide the linear bearing off the end of the carriage shaft.STEP 3--Insert a new linear bearing onto the end of thecarriage shaft with the tension adjustment screw pointingoutward. See FIG. 14. Adjust the tension screw of the linearbearing so when you radially rotate the linear bearing aroundthe carriage shaft there should be no free play between thelinear bearing and the carriage shaft.NOTE: Tension is too tight if you feel a cogging actionwhen you rotate the linear bearing around the shaft. Thiscogging is from the skidding of the bearing on the shaft andindicates tension screw is too tight.

Finally, sliding the bearing block back and forth should be asmooth uniform motion.

CARRIAGE LINEAR BEARING REPLACEMENT

SETTING THE BEARING TENSION CORRECTLYIS CRITICAL TO PROPER GRINDING. BEARINGSWHICH ARE TOO TIGHT OR TOO LOOSE WILLCAUSE POOR GRIND QUALITY. ALSO, BEARINGSWHICH ARE TOO TIGHT WILL HAVESUBSTANTIALLY SHORTER LIVES AND MAYDAMAGE THE SHAFT.

STEP 4--Slide linear bearing under carriage and attach withthe three screws.NOTE: Repeat Steps 2 thru 4 with the other threelinear bearings.STEP 5--After all four linear bearings are reattached to thecarriage check for correct bearing tension. The bearingtension is correct when you try to lift the carriage and canfeel no carriage movement, which is free play up and down.The most dependable method of checking free play is touse a magnetic base dial indicator attached to the traverseframe weldment and reading the vertical movement aboveeach bearing. This movement should be within .001" (.03mm) Also, when pulling the carriage in the traversingdirection, there should be only approximately a 3 lb force,with the belt disengaged. To check this attach a spring scaleto the carriage and pull parallel to the carriage shafts. Todouble check the assembly, slide the carriage assemblyfrom "end of travel" to "end of travel", it should have veryuniform resistance through the full range of travel.STEP 6--Replace the bellows carriage mounting bracketsonto the carriage. Replace front and rear shields.See FIG. 15.

ADJUSTMENTS (Continued)

The reel finger slide to the reel finger positioner has adovetail with an adjustable gib for tensioning. Tighten thegib set screws on the side so there is no free play in thedovetail slide. Check for movement when pushing onthe relief finger side to side with 20 lbs. (44kg)force. Make sure the knob assembly for adjusting therelief finger to the grinding wheel is rotatable by hand.The gib adjustment should be sufficient to maintain arigid position of the reel finger. See FIG. 16.

Check the knob assembly rotating tension by checkingthe tightness of the nylon plug to the knob assemblythreads. The tightness has to be sufficient so the knobassembly does not rotate during the relief grinding cycle.See FIG. 17.NOTE: To adjust the nylon plug you must lock the indexfinger assembly down and then adjust the reel fingerpositioner so the clearance holes line up with the nylonplug set screw.

Take up any free play between the tee knob assembly,reel finger slide and .375 threaded split shaft collar.Loosen the shaft collar locking cap screw and rotate theshaft collar until there is no end play. Retighten lockingcap screw on the threaded split shaft collar. See FIG.16.

GRINDING HEAD BELT TENSIONADJUSTMENTThe left side grip grinding wheel knob must be removedfor belt tensioning adjustment. Remove the six screwsholding, the two double tube clamps and the belt cover.For grinding motor belt adjustment, loosen the foursocket head cap screws that attach the motor. Adjustthe grinding motor for proper belt tension by pushing backon the motor and tighten the four socket head capscrews. The proper belt tension for the grinding head isto push down on the poly V belt half way between thetwo pulleys with 5 lbs. (2KG) of force and beltmovement dimensions to be .12 inches (3mm). See FIG.18. To verify belt tension mount the belt guard with twoscrews. Turn the motor on. If the belt is tensionedcorrectly, start-up torque of the motor through the pulleyto the belt should have zero slippage. If there is beltslippage when turning on the motor there will be a slightsqueal before the belt comes up to speed. When youachieve correct tension, reassemble all of theremaining parts that have been removed.

To adjust the tension on the traverse belt tighten thescrews and nuts located at the left side of the traversebelt. Tighten nuts until the comprension springsmeasure 3/4". See FIG. 25. If the springs are nottensioned equally, uneven loading on the traversesystem may cause parts to fail.

DO NOT OVERTIGHTEN.OVERTIGHTENING COULDDAMAGE THE BELT ORTRAVERSE DRIVE SYSTEM.

TRAVERSE CLAMP FORCE

If the traverse clamp is slipping during regular operation itmay be necessary to tighten the clamp. To tighten, loosenthe jam nut on the clamp tip. Screw the tip out so there is.10" gap between the tip and the Clamp Support Block.See FIG 26. Lock in place by tightening the jam nut againstthe clamp being careful not to move the tip. Verify thedistance between the clamp tip and block is still .10". The.10" setting allows slippage in a jam situation anddamage can occur if this adjustment is set to narrow.

CAUTION SHOULD BE USEDAS ADJUSTING THE TIP WILLAFFECT THE SLIP LOAD ANDCOULD DAMAGE THE CLAMPTIP, BELT OR TRAVERSEDRIVE SYSTEM.

REEL LIFT PIVOT BOLTS

There are four pivot bolts on the reel lift that must beadjusted correctly for proper lift function. Tighten thescrews and locknuts and then loosen 1/8 to 1/4 turnuntil the screw turns freely with fingers when the screwis under no load. See items marked "SCREWS ANDLOCKNUTS" below.


25

REEL LIFT SIDE BEARING ASSEMBLIES

There are four side bearing assemblies (two on each side) on the reel lift. The two onthe right side looking from the front of the grinder are fixed with screws and washers.The two on the left side looking from the front of the grinder are spring loaded againstthe lift frame. They must be adjusted correctly for proper lift function. These left sidescrews can be accessed through two holes on the inside of the vacuum chamber.Remove the vacuum cover and take out the vacuum. There are two plastic plugs onthe back wall of the vacuum chamber. Remove these plugs and raise or lower the liftuntil the spring retainer screws line up with the holes. Tighten the screws until tight(springs solid) with blue loctite no. 242, then back the scres out ONE full turn. Seeitems marke "B311613" below. When complete, reinstall plugs, vacuum and cover.

CONTROL BOARD POTENTIOMETER ADJUSTMENTS

POTENTIOMETER ADJUSTMENTS TRAVERSE DRIVE CONTROL (TDC)

Min. Speed--Factory set at full (CCW) 8:30. Do not change this setting.

(Right Traverse) Forward Torque--Factory set at full (CW) 4:30. Do not change this setting.(Left Traverse) Reverse Torque--Factory set at full (CW) 4:30. Do not change this setting.

IR COMP--Factory set to 9:00. IR COMP is current (I) resistance (R) compensation (COMP).IR COMP adjusts the output voltage of the drive which balances load to motor RPM. Regulation of a traversemotor may be improved by slight adjustment of the IR COMP trim pot clockwise from its factory-set position.Overcompensation causes the motor to oscillate or to increase speed when fully loaded. If you reach such apoint, turn the IR COMP trim pot counterclockwise until the symptoms disappear.

Max. Speed--Set at 3:30 for maximum voltage of 90 Volts DC to the traverse motor. When voltage is above90 volts DC, the traverse motor will start to pulsate and not run smoothly.

(Right Traverse) Forward Acceleration--Factory set at full (CCW) 8:30. Do not change this setting.(Left Traverse) Reverse Acceleration--Factory set at full (CCW) 8:30. Do not change this setting.

(DB) Dead Band is the potentiometer setting for the 50 or 60 Hz cycle control. Factory set to 9:00, works forboth 50 and 60 Hz. Do not change this setting.

Calibrating the DWELL TIME rotary DIP switch adjusts the amount of time the process remains in the stopposition after a limit switch is actuated. The DWELL TIME range is adjustable from 0 - 4 seconds. A DIPswitch setting of 0 sets the DWELL TIME to 0 seconds, while a setting of 8 sets the DWELL TIME to4 seconds. Dwell time is factory preset to #4 setting for a 2 second dwell time when reversing at each end ofstroke.

Diagnostic LED's indicate the function that is currently being performed:* POWER indicates that ac power is being applied to the control.* FORWARD indicates that the process is running in the forward direction (traversing left).* REVERSE indicates that the process is running in the reverse direction (traversing right).* PROX 1 FWD LIMIT lights when the forward limit switch is actuated (left prox).* PROX 2 REV LIMIT lights when the reverse limit switch is actuated (right prox).* DWELL lights when the process remains stopped after a proximity switch is actuated.

SPIN DRIVE CONTROL BOARD (SDC)The Spin Drive Control Board has three potentiometers on the lower board and two potentiometers on theupper board as shown on FIG. 27 and FIG. 28. These potentiometers have been set at the factory to thepositions shown on FIG. 27 and FIG. 28.

In the Relief Grinding Mode--The remote Relief Speed Pot (RSP) and the Relief Torque Pot (RTP) interact with each other. The (RSP) islocated on the upper spin board as a remote speed preset at 9:30. See FIG. 27. The (RTP) is located on thecontrol panel and is for relief torque adjustment.

Remote Relief Speed Pot (RSP) when rotated clockwise will increase maximum spin drive speed when inthe relief mode. This speed should never be above the 10:30 setting.

Relief Torque Pot (RTP) can vary the reel to finger holding torque for relief grinding. The recommendedstarting point is 30 in/lbs of torque setting. Never adjust the (RTP) potentiometer dial past the red line marking.Setting the reel to finger torque to high could cause the traverse motor system to not operate smoothly.

In the Spin Grinding Mode--the remote Spin Torque Potentiometer (STP) and the Spin Speed Pot (SSP) interact with each other. The(STP) is located on the upper spin board as remote torque preset at 2:00 for torque setting. See FIG. 27. The(SSP) is located on the control panel and is for spin speed adjustment.

The remote Spin Torque Pot (STP) controls maximum torque allowable in the spin grinding cycle only. Thisshould never be adjusted past the 2:30 position. If the reel does not turn check that the reel is free turning byhand spinning. The Spin speed Pot (SSP) controls reel spin speed, adjust as required. This controls the spindrive speed for spinning the reel.

POTENTIOMETERS ON THE LOWER BOARD OF THE SPIN DRIVE CONTROL (SDC) See FIG. 28. Maximum Speed Pot--The maximum speed is factory preset to 4:30 (fully clockwise) to allow for maximum spin speed.

Minimum Speed Pot--The minimum speed is factory preset at 8:30 (full counterclockwise) so zero speed is obtainable for spinspeed.

IR Compensation Pot--The IR Compensation is factory set at 9:00.

Regulation of the spin or relief grind spin motor may be improved by a slight adjustment of the IR COMP potclockwise from its factory-set position. Overcompensation causes the motor to oscillate or to increase speedwhen fully loaded. If this occurs turn the IR COMP pot counterclockwise until symptoms disappear.

REPLACEMENT OF GRINDING HEAD SHAFT & BEARINGS

Remove grinding wheel and grinding wheel knob. The Grinding Head Spindle Assembly consists of thegrinding head spindle and a ball bearing press fit together. The left side ball bearing is slip fit on the oppositeend. To replace the spindle assembly remove the left side grinding wheel grip knob, square key and beltcover. See FIG. 29. Loosen the 4 socket head cap screws on the motor plate to remove the poly-V belt.Loosen the 2 set screws on the spindle pulley and remove the pulley, square key and pulley spacer. Push onthe right hand side of the spindle assembly to compress conical washers so there is no pressure on theshaft retaining ring. Using a retaining ring pliers remove the small external retaining ring from the spindleassembly. You can now remove the spindle assembly out the right side by lightly tapping on the left end witha rubber mallet. The second ball bearing can be removed from the belt side of the Grinding Head Housing.

To reassemble place the 4 conical washers (2 Pair nested and then place the 2 pairs back to back) againstthe ball bearing on the new spindle assembly. See FIG. 30. Thoroughly clean the housing bore and theoutside diameter of both bearings. Apply blue Loctite #242 to the outside diameter of the two bearings. Slidethe spindle assembly into the right side of the Grinding Head Housing. Install the bearing sleeve against thebearing on the spindle assembly. Slip fit the new left side ball bearing onto the spindle assembly and intogrinding head housing. Install the 9/16-18 Locknut onto the spindle shaft and using a spanner wrench on theright side of the spindle and a 7/8 deepwell socket on the left side, torque the locknut to 20 Ft. Lbs.

Replace the square key and the pulley pushing the pulley against the locknut with no end play. Apply bluelocktie to the pulley bore before installation. Next install blue Loctite #242 on the pulley setscrews andtighten the two pulley set screws. Then remount the poly-V belt. (See Grinding Head Belt Tension Adjustmentin the adjusting section). Replace belt cover and square key and mount the left side grinding wheel grip knoband tighten the two set screws.

48

Possible Cause

Traverse Speed set too fast.

Lineal bearings for the grinding head carriage are outof adjustment (loose) or have grit buildup causinguneven traversing load.

Gib adjustment for the relief finger assembly is looseso reel finger has movement. When traversing to theright minimum grinding stock removal should be seenas compared with heavy stock removal whentraversing to the left.

Lineal bearings on the grinding head carriage are tooloose .

Lineal bearings in the carriage do not rotate freely.

Belt is slipping

Traverse Belt tension to loose

MECHANICAL TROUBLESHOOTING (Continued)

Checkout Procedure

Check roundness using a magnetic base dialindicator. Traverse speed should be set approximately12 ft/min. (4 meters/ min.) if roundness is varying.

Relubricate and adjust linear bearings per adjustmentsection. If problem persists, replace lineal bearings onthe carriage base. Check for any holes in the bellowsthat would permit any grinding grit penetration. Seeadjustment section for lineal bearing replacement.

Tighten the set screws for the gib adjustment. Seeprocedure in the adjustment section in the manual.

The lineal bearing must be preloaded to the traverseshafts with no vertical movement. See manualadjustment section for carriage bearing adjustments.

Check for grinding grit getting into the lineal bearingsand causing excessive driving torque of carriage.Abrasive noise is detectable when excessive grit is inthe lineal bearings. Replace the four lineal bearings inthe main carriage. Check bellows for holes andreplace if necessary.

Belt Clamp may have moved. See manual adjustmentsection for Traverse Clamp Force.

Check the spring length on left side of travese belt.See manual adjustment section for Traverse BeltTension.

PROBLEM--Reels ground have high/low blades

PROBLEM--Excessive grinding stock being removed whentraversing to the right in the relief grinding mode.

PROBLEM-- Grinding stock removal from reel is irregular duringspin grinding.

PROBLEM--Carriage traversing varies speed while grinding.

49

MECHANICAL TROUBLESHOOTING (Continued)

PROBLEM--Too heavy a burr on cutting edge of reel blades.

Checkout Procedure

Traverse speed should be set lower approximately 12ft/min. (meters/min.) for a smaller burr on cutting edge.

Grinding head travel was not setup parallel to the reelcenter shaft in vertical and horizontal planes. See Alignthe Reel Section in operator's Manual

The right hand side of the grinding wheel is not in fullcontact for relief grinding.See Operators Manual for NORMAL HELIX ANDREVERSE HELIX.

Possible Cause

Traverse speed set too high causing a heavy burron the reel blade when spin grinding.

PROBLEM--Cone shaped reel after grinding.

Grinding head travel not parallel to the reel centershaft.

The right side corner of the grinding wheel isalways to be in contact with the reel blade. This ishigh point of the relief finger.

PROBLEM--Relief grind on the reel blades do not go the full length of the reel.

PROBLEM-- Traverse speed is too slow.

Possible Cause

Lineal bearing in thecarriage are set too tight.

The two top and two bot-tom pivot screws arecompressing the conicalwasher too tight.

Check screw adjust-ment tension on nylonplug riding against thescrew thread.

Remedy

A. Readjust bearings for proper ten-sion. (for more detail see linealbearing replacement in theadjustment section of the manual.)

A. Tighten down the locknut until itbottoms out and back off 1/2 turn.Check to see if there is a coneshape to the washer. Four (4) pivotpoints.

B. Loosen set screw and check.(See adjustment section.)

Reason

When bearing preload is too tight, itcauses excessive loading to drive thecarriage.When traverse belt is disengaged, theproper traverse load is 2 to 3 lbs. Use atension scale to check. (A general guideonly.)

Have enough play so the crank turnssnugly but during operation it is free.

PROBLEM--Spin Drive cranks up and down too hard.
