6.3 INSTALL A COLLET IN THE MODEL 301
1. Select the proper size Collet for the outside diameter of the tube or pipe to be
squared. The size of the Collet is determined by the outside diameter of the
tube or pipe to be squared.
2. Do not drop the Collet.
3. Always place a hand under the Collet when installing or removing it from the
Model 301.
4. Remove the Knurled Nut from the end of the Model 301.
5. Insert the Collet into the tapered end of the Model 301.
6. Screw the Knurled Nut back onto the Model 301.
7.
Be sure that there is a light film of grease on Knurled Nut threads at all times
to prevent them from galling or freezing during use.
8. Back the Knurled Nut off just enough to allow insertion of the tube or pipe into
the Collet.
9. Partially tighten the Knurled Nut until the tube or pipe may still be moved into
position.
10. Move the tube or pipe approximately 1/16” (1.6 mm) from the Tool Bit.
11. As the Collet closes, the tube is drawn toward the Tool Bit.
12. Do not let the Tool Bit touch the tube or pipe. If it touches it will cause damage
to the Tool Bit or the Tube Squaring Machine when power is applied.
13. Tighten the Knurled Nut to prevent the rotation of the tube or pipe during
machining.
