Rotatable type machine tool

Abstract

A rotatable machine tool such as a precision boring tool has a head (2) that is detachably mounted on a shank type driving element (3). The head carries a removable cutting tip (9) and includes a bearing point (8) that wedgingly seats within a transverse slideway (7) in driving element (3). A slide (11), which is mounted in through bore (20) in head (2), has a male member (10) attached thereto which passes through a slot (24) extending between the bore (20) and an end face (19) of the head (2). Male member (10) is received within a bore (12) in driving element (3). A clamping screw (13) in drive element (3) interacts with male member (10) to cam it inwardly thereby clamping head (2) in position on drive element (3). The head (2) is transversely adjustable within slideway (7) by loosening screw (13) and adjusting opposed screws (32, 33) in head (2) which act on male member (10). The invention provides a driving interconnection between the drive element (3) and head (2) that is highly rigid, provides for easy diameter-wise adjustment of the head and is readily able to be assembled and disassembled for exchange of one head for another.
