LARGE DIAMETER BORING HEADS
ROUGH BORING COMPONENT SELECTION The table below determines the components such as extension slide (1), clamp bases (2) and insert holders (3) for each diameter range (ØD) and shows in which position (1 or 2) the clamp bases (2) have to be mounted on the extension slide (1). Further, this table also serves for the coarse diameter setting of the cutting edges by means of the scale on the clamp base (2) and the marking (4) on the insert holder (3). The required scale value is calculated by the difference between bore diameter and correction value ( α ). The insert holder has to be adjusted to the scale value. See example below.

FULL PROFILE ROUGHING The VPS boring process enables large material additions (up to 60 mm in diameter) to be bored in one operation with a relatively low drive power. Set cutting edge A to the drilling diameter and cutting edge B according to the material allowance according to the table.
