Drill Chuck Arbor

 

Collet Adapters

 

 

 

 

 

 

Your machine includes an R-8 drill chuck arbor and MT#3 drill chuck. Before use, the drill chuck must be installed onto the arbor. This drill chuck installation is intended to be semi-permanent.

Tip: For a permanent installation, chill the arbor in the freezer for 15 minutes before performing the following procedure. The taper will expand as it returns to room temperature, permanently locking the chuck.

To install the drill chuck onto the arbor:

1.Clean the grease off the drill chuck and all taper mating surfaces. Pay particular atten- tion to the MT#3 bore in the drill chuck—it must be free from all grease, oil, and debris.

2.Retract the drill chuck jaws fully by turning the body of the drill chuck counterclockwise.

3.Insert the arbor into the drill chuck. Tap the arbor lightly with a brass or other soft-headed hammer, as shown in Figure 38 to get a good fit.

Note: While it may not seem like there is anything keeping the drill chuck in place, the MT#3 taper fit provides a strong bond and will hold the drill chuck tightly.

Use the adapters as necessary to fit the tooling you wish to install. If you are using a tool with an MT#2 taper, you will need to use both adapters.

If the adapters become stuck together or tooling becomes stuck in one of the adapters, use the drift key to separate them.

To use the drift key:

1.DISCONNECT MACHINE FROM POWER!

2.Insert the pointed end of the drift key into the adapter slot so that it is against the top end of the lodged adapter or tooling.

3.Support the lodged adapter or tooling with a gloved hand to prevent it from falling out dur- ing the next step.

4.Gently tap on the broad end of the drift key. The drift key's wedge shape will force out the lodged adapter or tooling.
