BACK BORING INSTRUCTIONS 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 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 feasibility of the back boring operation and to select the best possible tool combination, these values can be calculated as follows:

C øD 1

Example: Calculation of the minimum entry bore diameter «C». Given: Back Bore Diameter øD=93mm Tool Combination EWN53, with Insert Holder No. 3, øD1=50 mm C= = =71.5mm øD + øD1 2 93 + 50 2 Counter clockwise spindle rotation is required for back boring operations. The cutting edge is at a shorter length than the boring head. Consider total length of tool. Check the space at the back side of the work piece ! CAUTION
