Twin cutter boring heads for highest performance
Rough boring with a tool that allows different cutting methods without the need for length adjustments or additional accessory components – this was the challenge for the design of a new twin cutter boring head.
The solution is simple and with a touch of genius:
A tool body with supports for insert holders of different heights, and insert holders of different lengths permit the adjustment of the cutting edges to the same length or to different lengths, just by a transposed mounting of the insert holders.
An adjust screw with a defined pitch permits individual diameter setting in both directions for each insert holders. Accordingly both cutting edges can be set to the same diameter for rotationally symmetrical roughing (RSS) or in diameter and length displaced, for double offset roughing (DVS). The selection of the roughing method is made according to the stock to be removed. With the RSS method approx. 10 % of the final diameter and with the DVS method approx. 20% of the final diameter can be removed in one cut.
Ground serrations on the mating surfaces of both tool body and insert holder permit a rigid connection and an accurate tool length. A diameter scale on the insert holders allows diameter adjustment without presetter. Tool body and insert holders are completely protected against corrosion by a high quality coating.
The new twin cutter tool program consists of 8 boring heads for roughing in the diameter range from Ø 20 – 203 mm. The boring heads with the KAISER connections CK1 to CK7 are equal in length and adjustment range to the KAISER precision boring heads EWN and EWB.
