Combination Tools
Combination tools are modular tool systems for drilling, countersinking, milling and thread milling which are primarily used in serial production. These sytems can often be applied when the use of a solid carbide tool is uneconomical. This is especially the case by machining large countersinking and chamfering, as the diameter differences between the operations are very large. Thus, significant time savings, rationalisation and quality improvements are possible in the machining of serial parts on CNC machining centers.
Components of combination tools
-
Basic holder in different shank designs
-
Central tool for drilling, rough boring or threading
-
Any reversing or changing inserts for spotfacing and chamfering operations
Advantages
-
Reducing the primary and secondary time
-
Association of multiple machining operations
-
Increasing flexibility by modular construction
