Suorita nämä toimenpiteet laitteiden DM-1 tai DT-1 osalta. Tässä toimintaohjeessa kerrotaan, miten kara vaihdetaan. Tammikuun 2014 jälkeen rakennetuissa koneissa käytetään keskipistevoideltavaa (MPO) karaa. MPO-karaa käytetään, kun kara vaihdetaan.

Clean the spindle head bore.

Stone the mating surface [1] on the spindle head casting.

Clean the motor adapter where it touches the spindle [3].

Do not stone the spindle lubrication port [2]. Keep all contamination out of the port.

Replace the spider coupling [1] if it is worn or damaged.

Replace the transfer tube [2] if it is worn or damaged.

Attach the red protective cap [2] to the bottom of the MPO spindle.

Put a 6" x 6" x 6" (152 mm x 152 mm x 152 mm) wood or aluminum block [3] on the table.

Put the MPO spindle on the block.

Make sure that the spindle lubrication port [1] is in the front.

Put a long 5/16"-18 screw [4] through the rear hole on the motor adapter. This screw helps you align the motor adapter to the spindle.

Put an indicator against the spindle coupler [1]. Zero the indicator.

Slowly turn the spindle with your hand to find the highest point on the coupler.

Put a mark on the point with a permanent marker.

Examine the coupler on the motor [2].

If the motor coupler has a mark, proceed to step 3.

If the motor coupler does not have a mark:

• Put an indicator against the motor coupler [2]. Zero the indicator.
• Slowly turn the motor by hand to find the highest point.
• Use a permanent marker to mark the point.

Apply grease to the transfer tube at these locations:

• the o-ring [1] at the top
• the socket [2] for the o-ring on the draw bar.

Push the transfer tube [4] onto the top of the draw bar [5].

Install the spider coupler [3].

Remove the tape [1] from the spindle lubrication port.

Apply a small quantity of grease to the spindle seal o-ring [2].

Insert the o-ring into the lubrication port [3].

Put the tape over the lubrication port of the spindle that was removed.

Slowly jog the Z Axis in the negative (-) direction until the head mount [1] is 0.5" (13 mm) above the spindle flange [2].

Use your hand to slowly turn the spindle coupler [5] until the mark on the spindle coupler aligns with the mark [4] on the motor coupler [3]. Align the (2) marks as closely as possible.

Slowly jog the Z Axis in the negative (-) direction.

 Caution: Lower the lift as you jog the Z Axis. The motor must be supported by the lift until the spindle is connected to the motor adapter.

Make sure the spindle is centered in the spindle bore.

Make sure the couplers engage smoothly.

Remove the temporary screw you used in step 1.

Install (4) motor mount screws [1] into the motor mount adapter [2].

Torque the screws. Refer to Haas Fastener Torque Specifications.

Remove the motor support lift.

Attach the oil supply fitting.

Connect the oil supply tube.

Put (4) screws [1] into the upper inside bearing block of the rocker assembly.

Put (4) screws [9] into the outer bearing block.

Put the rocker assembly [3] onto the spindle casting. Use the lower bearing block [2] on the inside as a guide.

Use a dowel pin [8] to align the outside bearing block.

Put the rocker arm [7] through the yoke [5] on shaft from the air cylinder.

Push the clevis pin [4] through the arm and the yoke.

Put the C-clip [6] onto the clevis pin.

Torque all of the screws. Refer to the Haas Fastener Torque Specifications.

Make sure the rocker assembly is correctly adjusted.

 Note: The illustration does not show the spindle and spindle motor.

Use the spring installation tool to attach the spring to the striker block.

Refer to DT-1 - Spindle Rocker Arm - Spring Installation Tool - Instructions.

Install the fan assembly onto the top of the spindle head.

Install the spindle head covers.

Liikuta nykäyssyötöllä Z-akselia liikealueen pohjaan.

Paina[EMERGENCY STOP].

Poista Karan tuuletinkokoonpano.

Irrota keinuvarsikokoonpano. Toimi seuraavasti:

• Irrota C-pidike [5] haarukkatapista [6]. Poista se painamalla haarukkatappia.
• Irrota jousi [4] vastalevystä.
• Löysennä sisäpuolen laakerilevyn [2] (4) ruuvit [1].
• Löysennä ulkopuolen laakerilevyn [8] (4) ruuvit [7].
• Irrota keinuvarsikokoonpano koneesta
• Älä poista sisäpuolen laakerilevyn alapuolta [3].
• Irrota laakerilevyjen lieriösokat.

 Huomautus: Kuvassa ei näy karaa eikä karamoottoria.

Nykäyssyötä X- ja Y-akseleita, kunnes taulukko on suoraan karan alla.

Paina [EMERGENCY STOP].

Aseta 6" x 6" x 6" (152 mm x 152 mm x 152 mm) puinen tai alumiinilevy [2] pöydälle.

Kiinnitä suojus [1] koneeseen asennettuun karaan.

Vapauta [EMERGENCY STOP].

Paina [RESET] (Nollaus) -painiketta hälytysten kuittaamiseksi.

Nykäyssyötä Z-akselia negatiivisessa (-) suunnassa, kunnes kara on levyn päällä.

Paina[EMERGENCY STOP].

Kiinnitä nostin kiinnikkeeseen [3] enkooderia varten.

 Varoitus: Kun akseli on erotettu moottoriadapterista, nostimen on tuettava moottorikokoonpanoa.

Irrota öljynsyöttöputki.

Irrota öljynsyöttöliitin.

Irrota (4) ruuvit [2], joilla moottoriadapteri on kiinnitetty [1] karaan.

Irrota (6) pidinruuvit [4] karan laipan [3] osalta.

Vapauta [EMERGENCY STOP].

Paina [RESET] (Nollaus) -painiketta hälytysten kuittaamiseksi.

Nykäyssyötä hitaasti Z-akselia 0,001" suuruisin inkrementein positiivisen (+) suuntaisin askelin 0,04" (1 mm) etäisyydelle.

 Huomautus: Kara [2] putoaa 1/32" (1 mm) karan valusta [1].

Jos kara ei putoa, käännä karaa kiristysavaimella 1/4 käännöstä myötäpäivään, jotta se löystyy.

Nosta moottorikokoonpanoa [3] nostimen avulla samalla, kun nykäyssyötät Z-akselia.

Nykäyssyötä Z-akselia positiiviseen (+) suuntaan, kunnes voit irrottaa karan [4].
