VersaMax Boring System<br />
Balanceable Fine Boring Head<br />
Setup Instructions<br />
.787-6.024” (20-153)<br />
<br />
Setup Instructions<br />
1. Clean the pilot, bore, and both faces before attempting to assemble. The Alpha connection is assembled by inserting the pilot<br />
into the toolholder bore and threading together. Tighten the connection to the recommended torque value.<br />
MAXIMUM TORQUE VALUES FOR ALPHA CONNECTION<br />
Alpha 1 = 37 ft-lbs<br />
Alpha 2 = 59 ft-lbs<br />
Alpha 3 = 118 ft-lbs<br />
Alpha 4 = 295 ft-lbs<br />
2. Mount the Fine Boring Insert Holder to the Fine Boring Head using the button head screw.<br />
3. CAUTION: before turning the fine adjustment dial, be sure to loosen the side locking set screw (1). If the locking screw is not<br />
fully loosened and the dial is turned, the life and accuracy of the adjustment mechanism will decrease. Loosen the side locking<br />
set screw and turn the dial (2) to achieve the desired size. Tighten side locking set screw (1) (CAUTION: DO NOT OVER TIGHTEN).<br />
4. To balance the head, adjust the top collar (closest to the cutting edge) such that the desired bore diameter marking on the head<br />
and collar line up (3). Some interpolation may be necessary. Lock the collar in place. Next, line up the bore target marking on<br />
the bottom collar with the marking on the top collar (4). Lock the bottom collar in place.<br />
5. You are now ready to bore a test hole. Measure the test hole size and adjust the boring head, if necessary, to compensate for<br />
cutting pressure (see step 3).<br />
6. After use, disassemble, clean, and oil parts to prevent rust while in storage.<br />
