M1036 Micro Mill

Collets

The collet chuck (an optional accessory) for the micro

mill offers increased precision and rigidity compared to

the drill chuck. Each collet will only fit tooling with a

specific shaft diameter. This collet set includes

⁄

" collets.

To install the collet chuck, do these steps:

1. UNPLUG THE MICRO MILL!

2. Remove the drill chuck and clean the arbor and

collet chuck tapers with denatured alcohol.

3. Push the collet chuck onto the arbor.

4. Place a piece of wood on the compound slide table

and use the downfeed lever to firmly press the

collet chuck against the piece of wood (see

Figure

23) to seat the collet chuck on the arbor.

To install the collet in the collet chuck, do these steps:

1. Place the grooved end of the collet into the collet nut

until the off-center lip of the collet nut snaps into the

collet groove. See

Figure 24.

Note: This lip and groove pulls the collet from the

spindle when the collet nut is removed.

2. Place the collet nut and collet into the collet chuck

and finger tighten the collet nut onto the collet

chuck.

3. Insert the bit into the collet, place a hex wrench

through the hole in the spindle, and tighten the

collet with a 22mm wrench (see

Figure 25).

To remove a bit from the collet chuck, do these steps:

1. Protect the table surface with a piece of cardboard

or hold the cutter or tool with a shop towel to pre-

vent it from falling out of the collet.

2. Place a hex wrench through the hole in the spindle

and loosen the collet nut with a 22mm wrench until

the bit is free.

Note: Remove the collet chuck in the same manner as

removing the drill chuck.
