Loading Tooling

Your Model G0704 features an R-8 spindle taper, which gives the freedom to use standard R-8 cutting tools and collets. These optional collets come in many sizes, typically ranging from 1⁄16" to 7⁄8" and 3mm to 20mm, and should be matched to your cutting tool shank size.

To install the tooling:

1.DISCONNECT MILL/DRILL FROM POWER!

2.Remove the drawbar cap.

3.Carefully clean the surface of the tooling and spindle taper. Ensure that it is free of debris and is lightly oiled.

4.If you are using a cutting tool and collet, insert the cutting tool into the collet, then insert the collet up into the spindle taper, making sure the slot in the collet lines up with the pin in the spindle.

if you are using a cutting tool that installs directly into the spindle, insert the tool into the spindle taper, making sure the slot in the tool lines up with the pin in the spindle.

5.slide the tooling upward until it makes con- tact with the drawbar threads.

6.Hand thread the drawbar into the tooling until the tooling draws up into the spindle taper.

7.Use the included spindle pin to prevent the spindle from turning while you use an 8mm wrench to tighten the drawbar.

Note: Do not overtighten the drawbar. Overtightening makes collet removal difficult and will damage the drawbar threads, collet, and the spindle taper. Keep in mind that the taper keeps the collet and tool in place. The drawbar simply aids in seating the taper.

To remove the collet:

1.DISCONNECT MILL/DRILL FROM POWER!

2.Remove the drawbar cap.

3.Lock the quill in place with the quill lock lever.

4.Use the included spindle pin to prevent the spindle from turning while you use an 8mm wrench to loosen the drawbar 2–3 turns. DO NOT continue loosening the drawbar without supporting the collet or it will fall from the spindle.

LACERATION HAZARD! Leading edges of end mills and other cutting tools can be very sharp. Protect your hands with gloves or a shop towel when handling.

NOTICE

The Model G0704 drawbar will extract the arbor from the spindle. Once the arbor or collet has broken free from the spindle taper, be sure to properly support it while continuing to loosen the drawbar. Failure to properly support the arbor or collet while loosening the drawbar will result in the arbor or collet falling out of the spindle, causing damage to machine components.

5.protect the table surface with a piece of cardboard and hold the cutter/tool with a shop towel to prevent it from falling out of the collet. Continue loosening the drawbar until the collet is freed from the spindle.
