BRIDGEPORT SERIES I MILLING MACHINE

Carefully remove protective crating and skids so that the machine andparts are not marred, scratched or impaired. In the event of damage intransit, communicate AT ONCE with our representative and the trans-portation company making delivery.

Machine should be lifted by placing a sling under the ram as illustratedon page 5.

SHORTAGES Check shipment carefully, against the itemized packing listwhich is included in the parts box. In case of shortages, report themIMMEDIATELY to the representative from whom the machine was purchased,indicating parts not received which have been checked on the packing list.

CLEANING Thoroughly clean protective coating from machine withsuitable cleaning solution.

Do not move the table, saddle, knee or any movable part until all wayshave been well cleaned and lubricated. Then, by hand, move table,saddle and knee to limit stop in one direction. Clean and lubricateexposed ways and then move each unit to the opposite limit stop andsimilarly clean and lubricate the exposed ways. Loosen bolts to unlockthe ram, and move it forward and backward to the full length in order toclean and lubricate.

POSITIONING HEAD UPRIGHT Loosen four locknuts (#157 page 35), pullstop pin (#133 page 26), out to detent and rotate head to vertical position.Proceed with alignment of head as described on page 8. Tighten nutsevenly, using normal pressure. Care should be taken to avoid excessivepressure since this will cause distortion in the quill. Tighten all nuts to25 ft. lbs. torque-then repeat to 50 ft. lbs.

PLACING ON SOLID FOUNDATION

The column and base are cast in one piece. When setting machine on aconcrete foundation, it is advisable to use a little grout (thin mortar) totake care of any unevenness in the concrete as well as to provide a solidfoundation at all points.

When setting machine on a floor that has any surface irregularities, shimsshould be used to correct this condition to the greatest extent possible.See Figure 2 for installation layout.

NOTEIT IS RECOMMENDED THAT THE MACHINE BE SECURED TO THEFLOOR TO PREVENT MOVEMENT OR TIPPING DUE TO OFF-CENTERLOADING.

Before securing machine to floor (i .e. tightening hold down bolts), makecertain that all four corners are making contact with the floor aftermachine is leveled. If above condition is not met, it is possible to twistthe column and put a bind into the ways.

LEVELING MACHINE Set machine by leveling the work table lengthwiseand crosswise with a precision instrument. After leveling machine, lowerthe knee and remove protective material from between head and table.

HANDLES When crating, the three ball crank handles are sometimes turnedto face the machine. In these cases the handles should be reversed beforeoperating.

CONNECTING POWER SUPPLY To connect the machine to the plant sup-ply, have qualified electrician proceed as follows:

1. Check required machine voltage against power supply to ensurethat they are compatible.

2. Connect machine wiring to power supply making sure connectionis in compliance with local safety regulations.

3. Check for correct spindle rotation. In the HIGH SPEED range,the spindle should rotate clockwise when viewed from the topof the machine.

NOTEDRUM SWITCH AND HI-NEUTRAL-LO LEVER MUST BE IN HI RANGE.

ALIGNMENT OF HEAD

In case of precision boring or work of that nature, where it is necessaryto have head perfectly square with the table, use method prescribedbelow. For general milling use, graduations provided on the head areclose enough. To set head perfectly square with table, see Figures 3 and4. This may be done with Ram adapter (#2 page 26) on Ram (#10 page 26),by adjusting Ram adapter through vertical adjusting worm shaft (#8 page26). Loosen four locknuts (#157 page 34) but leave drag on same for fineadjustment. To square head to table in the longitudinal axis, mountindicator as shown in Figure 4.

NOTEWHEN INDICATING AS IN FIGURE 3, IT SHOULD BENOTED THAT THE TABLE IS FITTED TO BE SLIGHTLYHIGHER IN FRONT, USUALLY ABOUT .0005".

CLAMPING TABLE, SADDLE AND KNEE.When milling with longitudinal table feedonly, it is advisable to clamp the knee tothe column and the saddle to the knee toadd rigidity to these members and pro-vide for heavier cuts with a minimum ofvibration. The saddle locking lever islocated on the left-hand side of saddle.

Excessive pressure can cause slight tablebind. Use moderate clamping pressure,as this will hold saddle sufficiently.

-LOCK SADDLE LOCKING LEVER

The table clamp lever is located on frontof saddle and should always be clampedwhen longitudinal movement is notrequired.

TABLE CLAMP LEVER

The knee clamping lever is at the leftside of the knee and should be drawn up-ward to clamp the knee. This is onlya tension brake and will not lock theknee completely. Leave clamped at alltimes unless using knee in operation.

REMOVING TABLE. Remove as follows: ball crank handles, dial holders,bearing brackets. Lead screw will then turn all the way out so it can beremoved. When this is accomplished, the table can easily be taken off bysliding it from the saddle. See Figure 9.

REMOVING SADDLE. Follow along the same lines as removing table;however, it is necessary to remove the entire front bracket assembly.Next, remove the cross feed nut bracket which is made accessible byremoval of the table. See Figure 9.

ASSEMBLY INSTRUCTIONSFOR MOUNTING 2-J VARIDRIVE ATTACHMENT TO RAM ADAPTER

Lift the attachment. Insert the four tee bolts into the ram adapter andposition them to match the bolt holes in the attachment.

Slide the attachment onto the bolts, insert the spacers and washers andsecure with the nuts.

Tighten all the nuts with 25 ft. lbs. of torque, and then repeat with50 ft. lbs.

CAUTIONIMPROPER TIGHTENING OF THESE COULD CAUSEA CHOPPY QUILL MOVEMENT

LUBRICATION:

The useful life of this attachment will be determined to a large extent byproper lubrication. Carefully observe the nameplate recommendations anaavoid substitutions.

OPERATING INSTRUCTIONS:

SPEED CHANGE HANDWHEEL (16, Figure 10): DO NOT attempt to changespindle RPM unless the motor is running. Dial speeds will only beapproximate. Belt wear will cause a slight variation in speeds from whatis indicated on the dial.

When tightening or loosening the drawbar (#14 page 38) it is necessaryto lock the spindle. To accomplish this, use the spindle brake (3) whichis located on the left side of belt housing, turning it either to the rightor left until it binds, then raise the quill feed handle (13).

Drawbar (#14 page 38) has 7/16-20 right hand thread and should betightened with normal amount of pressure using wrench furnished withmachine. To loosen collet back off drawbar and if collet does not openimmediately give knob on top of drawbar a slight tap. Spindle hasnon-sticking taper and collet should release readily.

14

Figure 10. 2J Milling Attachment

15

SPINDLE BRAKE (3, Figure 10): Brake lever can be moved in eitherdirection to stop spindle; however, when locking spindle, lever shouldbe moved to right or left and then raised. When brake is worn out ithas to be replaced. There are no adjustments to be made.

CAUTIONBE CERTAIN THAT THE SPINDLE BRAKE IS RELEASEDBEFORE STARTING THE MOTOR. THIS IS IMPORTANTAS THE MOTOR CAN BE DAMAGED IF SWITCH IS TURNEDON WITH BRAKE IN LOCKED POSITION.

HIGH-LOW RANGE SWITCH (1): This is the motor reversing switch. Whenthe attachment is in direct drive (High Speed) the motor and spindle areturning in the same direction. When the attachment is in "Back Gear"(Low Speed) the spindle would run backwards unless the motordirection is reversed.

The back-gear lever is marked Hi-Lo. This will indicate the properswitch position. They should be alike or the spindle will run backwards.

HI-NEUTRAL-LO LEVER (15): This lever is used to put the attachmentinto either back gear or direct drive. Rotate the spindle by hand tofacilitate meshing of clutch or gears.

Neutral can also be obtained at mid-way position. After a long period ofuse, the neutral position may cause noise (in neutral only) by allowing theclutch teeth to rub each other.

This can be corrected by loosening set screw (#64 page 36) and reversingthe position of the detent plate (#65 page 36).

Neutral is provided to permit free spindle rotation for indicating andset-up work.

In the high speed position (direct drive) the spindle is driven by taperedclutch teeth. If the clutch is not meshed tightly, clutch rattle will beheard. This can be avoided by moving the detent plate upward as theclutches wear. This is also the reason for possible loss of neutral,requiring the reversal of the detent plate.

CAUTIONDO NOT shift Hi-Lo Lever while motor is running.

POWER FEED TRANSMISSION ENGAGEMENT CRANK (4, Figure 10) : En-gages power feed worm gear. When lever is in right hand hole, thepower feed worm gear is engaged. To disengage worm gear, pull knobout and crank handle in clockwise or down direction and move toopposite position.

NOTECRANK CANNOT BE SWUNG AROUND IN COUNTERCLOCKWISE DIRECTION; HOWEVER, NO DAMAGEWILL OCCUR IF MOVED IN THIS DIRECTION. TOENGAGE THE WORM A CLOCKWISE MOVEMENT ISREQUIRED.

CAUTIONPOWER FEED WORM GEAR MAY BE ENGAGED WHENSPINDLE IS ROTATING, HOWEVER, IT SHOULD BEENGAGED GENTLY TO AVOID DAMAGE TO WORMGEAR. THE WORM GEAR MAY BE DISENGAGED ATANY TIME. DO NOT USE POWER FEED AT SPEEDSABOVE 3000 RPM.

IMPORTANT : It is recommended that the Power Feed worm gearbe disengaged whenever the power feed is notrequired. This will avoid unnecessary wear onpower feed worm gear.

QUILL FEED SELECTOR (5): This crank is used for selecting thethree feeds; .0015", .003" and .006" per revolution. It is shifted bypulling knob out and turning from one position to the other. Feeds arestamped on cover below indentation hole. Feed is more readily engagedwhen spindle is running.

FEED REVERSE KNOB (7): Position of this knob depends upon directionof spindle rotation. If boring with right hand cutting tools, pull feedhandle towards operator until clutch becomes engaged.

Neutral position is between forward and reverse position. It is recom-mended that the handle be left in neutral position when not in use.

MANUAL FEED HANDWHEEL (6): Feed reversing knob should be inneutral position and feed control lever (8) engaged. Clockwise rotationof handwheel moves quill down. The Manual Feed Handwheel and theQuill Feed Handle may be disengaged by moving them outward about1/8".

17

NOTEThe feed control lever must be engaged in orderto use manual feed controls. The Quill FeedHandle and Manual Feed Handwheel may be takenoff when not in use.

FEED CONTROL LEVER (8): Engages over-load clutch on pinion shaftwhen positioned left and will stay engaged until either quill stop comes incontact with micrometer adjusting nut, forcing feed control lever to dropout automatically, or released manually by engaging lever to right.

NOTEThe Feed Control Lever is carefully set at plantto disengage automatically when quill stop goesagainst micrometer adjusting nut or against throwout pin at top. However, if this should go out ofadjustment, it may easily be brought back byregulating the socket set screw located at bottomof tripping rod (item no. 144 page 35).

CAUTIONWHEN ADJUSTING THE SOCKET SET SCREW,CHECK AUTOMATIC DISENGAGEMENT IN BOTHDIRECTIONS; THAT IS WITH QUILL-STOP NUT(#161 PAGE 35) AGAINST THE FEED TRIP LEVER(#145 PAGE 35) FOR DOWN POSITION, ANDAGAINST REVERSE TRIP BALL LEVER (#183PAGE 35) FOR THE UP POSITION.

QUILL FEED HANDLE (13): May be removed by simply pulling handleoff. It is recommended that handle be disengaged when using powerfeed.

QUILL STOP KNOB (14): Is used to disengage automatic feed in eitherdirection as well as the setting point for working to given depths.

MICROMETER NUT (11): This nut is used for setting of depths. Eachgraduation on nut indicates .001" of depth, it reads directly to scalemounted along side of it. Depths may be obtained by setting micrometernut in conjunction with quill stop.

QUILL LOCK (12) : This is a friction quill lock to be used when quill isin stationary position such as milling operations. It is recommended thatthis lock be used whenever quill movement is not desired.

18

POSITION OF RAM: Can be regulated by loosening two Ram Lock Studs(#119 page 26) on turret (#124 page 26) and pulling the ram (#10 page 26)in or out to desired position.

CAUTIONCARE SHOULD BE TAKEN TO LOCK RAMSECURELY AFTER SETTING.

NOTEIt is recommended that on heavy milling work,head should be kept as close to column aspossible, where maximum rigidity is obtained.

RECOMMENDATIONS:

Use 2, 3, or 4 flute end mills. Eight flute end mills are usually not assatisfactory for general milling. When using shell mills, face mills or anyother tooling, proper machining practice should be observed.

Power feed can be used for drills up to 3/8" in diameter. Use manualfeed for drills larger than 3/8".

Overload clutch is set at factory to hold up to 200 lbs. down pressure onquill, which will accommodate drills up to 3/8" diameter in mild tool steel.

CAUTIONTHIS CLUTCH SHOULD NOT BE TAMPEREDWITH IN THE FIELD.

OPERATING INSTRUCTIONS

CAUTIONDO NOT TRY TO CHANGE SPEED POSITIONUNTIL MOTOR IS RUNNING. THIS COULDCAUSE BREAKAGE OF PARTS.

Spindle Speeds are adjusted by turning speed change handwheel (#21 page36) on the front of the belt housing. There are two ranges shown; 60 to500 and 500 to 4200.

60 to 500 is obtained through the back-gear drive and is referred to as thelow range. To engage the back-gears, use the lever marked Hi-Neutral-Loon the right rear side of the attachment. Move this lever to the "LO"position and use the low range on the down switch.

When shifting to "LO," DO NOT FORCE THE LEVER if the back gears do notmesh. Hold the lever so that the gears are clear of one another, rotate thespindle nose by hand until the gears line up, then put the unit in "LO"(back gear)

10

500 to 4200 is obtained through direct drive and is the high range. Thesame lever and switch as above are used; selecting the "HI" range.

When shifting to "Hi," do not force the lever if the clutch teeth do notmesh. It is a simple matter to engage the brake and rotate the spindlenose by hand until the clutches engage.

Wear on the vari-drive belt will cause a slight change in the speeds to thatshown in windows (#22 page 36) on the dial. This can be corrected asfollows. Crank the speed change handwheel (#16, Figure 10) snuglyagainst the high speed stop. (This will be near the 4200 reading on thedial.) Use a tachometer to determine the spindle speed, then turn thepivot stud (#16 page 38), after loosening the jam nut (Item #7 page 38)until the spindle speed registers 4200 on the tachometer; tighten jamnut.

Now reposition the speed dial plate to match the tachometer reading. Thisis done by loosening the Hex nut (#1 page 36) until the spindle speedregisters 4200 on the tachometer; tighten jam nut.

CAUTIONTRY TO AVOID SHIFTING THE HI-LO LEVERWHEN THE FEED WORM IS ENGAGED.

DO NOT LOOSEN the 3 hex nuts (#61 page 36) on the upper part of theQuill Housing (#192 page 34). These are set at the factory and are usedonly for alignment.

SWIVELING THE VARI-DRIVE may be accomplished by loosening the lower3 hex nuts (#47 page 36) attaching the Vari-Drive unit to the quillhousing and then swiveling to any desired position. See arrangement ofT-Bolts (#45 page 36) in Gear Housing(#44 page 36) for this purpose.

WARNINGCARE MUST BE TAKEN TO SECURE THE NUTS(#47 page 36) WHEN THE ATTACHMENT IS INPOSITION, BEFORE THE MOTOR IS TURNED ON.

REMOVING THE MOTOR (See Figure 11): Run the attachment to thebottom of either speed range and shut off the motor. This puts thevari-drive belt in the best position for disassembly.

DISCONNECT THE POWER and then remove the switch fromthe side of the belt housing.

Remove the cover (#76 page 36) (B, Figure 11) at the lowerend of the motor shaft. Use two cover screws (#75 page 36)(A) to fasten the spring (#44 page 38) (C) on the lower endof the motor shaft, to the lower motor vari-drive pulley(#43 page 38). This will reduce the hazard of personalinjury that is always present when a heavy spring is undercompression. When the pulley, spring retainer (#45 page38) and spring are securely fastened as a single unit,crank the speed change handwheel (#16 Figure 10) to topspeed position.

Now remove the screws (#9 page 38) (D) that fasten themotor to the belt housing. The motor should be liftedslightly and pulled firmly away from the spindle andtoward the rear of the belt housing. This will pull thevari-drive belt (#27 page 38) deeply into the spindlepulley (#25 page 38), providing the slack needed to shipthe belt over the motor pulley (#43 page 38).

Now lift the motor high enough to rest the motor baseGENTLY on the adjusting screw (#16 page 38) (E) seendirectly in front of the motor flange. The belt can nowbe slipped over the lower pulley and the motor removedfrom the housing.

CHANGING VARI-DRIVE BELT (Figure 12)

Complete the above procedures for removing the motor, then remove thethree screws (#1 page 38) (A, Figure 12) and lift out the top bearing cap(#2 page 38) (B). Looking down inside of the housing, locate and re-move two socket head cap screws (#17 page 38) and sleeves (#19 page 38)(C). Next, remove the four screws (#6 page 38) (D) and the screw(#55 page 38) (E) holding the belt housing (G) to the base (#53 page 38).Unscrew and remove the two lower screws (#25 page 36) in the speedchanger bracket just below the speed dial (#2 page 36) (F).

NOTEOn Models with plastic face plate (#27 page 36)remove screws (#23 page 36) first.

Figure 12. Removing the Vari-Drive Belt

The belt housing, complete with speed changer bracket, is now removedfrom its belt housing base (#53 page 38). A slight blow under the speedchanger bracket (#5 page 36) may be needed to separate the belt housing(#10 page 38) from the belt housing base (#53 page 38).

Remove the old belt (#27 page 38) and replace it with a new belt. DO NOTuse a substitute belt purchased from other than a Bridgeport Dealer.Vibration and heat could result from the use of the wrong belt.

22

CHANGING TIMING BELT (Figure 13)

Complete the operation for removing the motor. Then put the Hi-Neutral-Lo lever (#15, Figure 10) in the Lo position, remove the drawbar(#14 page 38) (A, Figure 13) and lower the spindle.

Remove screws (#55 page 38) (B) holding the upper and lower housings(#63 page 38) together, including the two lower screws (C) in speedchanger bracket just below the speed dial.

Figure 13. Removing Timing Belt

A slight blow under the speed changer bracket (#5 page 36) may beneeded to separate the upper housing (D) from its base.

As the housings are being separated, the HTD belt (D) (#36 page 36)still connects them, resisting the separating movement. The separationcan be assisted by gently pushing the belt off the large pulley (#86 page36) as the upper housing is being raised.

Remove the old belt and replace with a new belt.
