Introduction

Obsoletion of main pcb tooling holder shaft has created inability to supply replacement spindle units that have failed on site. This procedure will extract required parts from failed units to provide a supply of parts required to create exchange units for R0000164 spindles

Étape 1 - Remove drive pulley

1. Remove 2 off M6 grubscrew from pulley
2. Remove pulley from shaft

...If pulley is tight to remove, use lever bars to prise pulley off

Étape 2 - Remove Grubscrew and extract internal assembly

1. Remove locating grubscrew
2. Remove blanking grubscrew
3. Apply heat to spindle housing to swell bores

...The housing needs to be heated just enough to allow the internal assembly to be pressed out. To check when the correct temperature is obtained, use a hide hammer to gently hit the end of the spindle. If the spindle moves in the direction shown the correct temperature has been reached

4. Use tool press to push internals out of housing in direction shown

5. Use a drift to remove remaining bearing from housing

...Caution should be used when using a drift to remove bearing as damage can easily be caused to internal side wall of housing

Étape 3 - remove quill coupling

1. Remove 2 off M6 grubscrews from Quill
2. Apply heat with heat gun to area indicated 2 to melt adhesive holding the quill on to the tooling spindle

...Use an M6 bolt in the m6 grubscrew hole to stop the quill rotating in the vice when rotational force is used

3. Change spindle to a vertical position and use a 22mm spanner to undo the quill housing from the probe

...This will be extremely tight, so controlled rotational force will be required to separate the two parts

4. The two parts shown separated. M6 studding visible is the mechanical connection between the two parts.

Étape 4 - Remove m6 stud from tooling spindle

1. Clamp M6 studding in vice to hold in position

...If M6 studding slips in vice when rotation the tooling spindle, file 2 small opposing flats onto the M6 studding to stop rotation in the vice jaws

2. Apply heat with a heat gun in the area indicated to melt and break the stud lock that will have been applied. Use a 22mm spanner on the flats indicated to rotate the tooling shaft off the m6 studding

3 Studding and tooling shaft shown separated

Étape 5 - Remove components from tooling shaft

1. Use tool press to push tooling shaft through bearings

2. If tooling press is unable to split bearings from shaft , impact must be used.

To do this, add a m6 set bolt to the hole shown. This will act as protection for the tooling shaft from the impact

Hold the assembly in the vice as shown and impact the set bolt with a hammer in the direction shown to break the seating of the bearings on the shaft

3. components shown removed from the tooling shaft

Étape 6 - Parts Required to be reused

IF requested, the following parts will require refurbishing and reusing for a new spindle rebuild.

1. Spindle Housing D0006018
2. Tooling spindle and Nut H0006011

Étape 7 - Refurbishing D0006018

1. Check internal
