BACK BORING INSTRUCTIONS<br />

For back boring, it is required to enter into the bore off centre, with a tool adjusted to the back bore diameter. In this respect, the back<br />

bore diameter «D» as well as the diameters of the entry bore «C» and the tool body «A», are related to each other. In order to check the<br />

feasibility of the back boring operation and to select the best possible tool combination, these values can be calculated as follows:<br />

Example:<br />

Calculation of the minimum entry bore diameter «C».<br />

Given:<br />

Back Bore Diameter øD=93mm<br />

Tool Combination EWN53, with Insert Holder No. 3, øD1=50 mm<br />

CAUTION<br />

Counter clockwise spindle rotation is required for back boring<br />

operations. The cutting edge is at a shorter length than the boring<br />

head. Consider total length of tool. Check the space at the back<br />

side of the work piece<br />
