Abstract

As widely known, the better machining accuracy, higher machining speed and heavy-duty cutting capability can be facilitated with secure grasping and accurate holding of both the work and the tool. In due course, there are a considerable number of the devices called the attachment for such purposes, and in general the attachment can be roughly classified into those for work and tool holding. In this context, we must be aware that some devices may change their roles from work to tool holding depending upon the machining requirement.

The fixture and jig is an assembly of a considerable number of parts, and thus the joint of both the parts determines its performance to large extent. From the viewpoint of the machine tool joint, there are various interesting research subjects extremely considering the differing magnitude of the joint deformation at each clamping point in the fixture and jig. In retrospect, there have been no noteworthy researches since 1960s apart from those of Shawki and Abdel-Aal (Inter. J. Mach. Des, Res. 1965; 5:183 and 6:31).

In the independent four-jaw chuck, in general, the jaw is monolithic, and thus should be once released from and again engaged to the screw for travelling the jaw after reversing the gripping surface for either the outer or inner surface of the work.

Face driver with hardened multiple burins is called “der Stirnseitenmitnehmer” in German term. Thus, the face driver appears not adequate translation by nature.

This driver was exclusively contrived by GF for its own automatic copying lathe, for example, type KDM-9/80, in the 1960s, in which the allowable work diameter in maximum is 200 mm. The driver is thus called the “GF Work Driver”.

IWF (Institut für Werkzeugmaschinen und Fertigung; Institute for Machine Tools and Fabrication) of Technical University of Berlin once developed a prototype of higher-speed chuck made of CFRP. This chuck is available for machining of the work of 90 mm in diameter while rotating up to 15,000 rev/min. The chuck is furthermore designed in consideration of the directional-orientation properties of CFRP adequately.
