Böni Quick-change Tool Holders have been made for more than 70 years
Constructional characteristics of the Böni Quick-change Tool Holders are its extremely solid, stable and of simple design. The tool post is made of forged steel which has been carefully case hardened. Its square shape is best suited to the bearing surface of the cross slide. A square bearing surface is very important because it creates a positive connection with the machine up to a point just below the tool cutting edge. This means there is less strain an the cross slide of a lathe than from a relatively small bearing surface at the centre of the cross slide. A strong bolt prevents the tool post from turning, but it can be released at any time if it has to be moved to another position. Precision-ground veeways on both, tool post and exchange holders interact with hardened and ground eccentric shafts, which are seated in precision-honed bores, to connect these Parts rigidly, allowing heavy and interrupted cuts to be made without difficulty. Since the veeways suffer virtually no wear there's no limit to accuracy or rigidity. The BOENI quick-change tool holder can be cleaned quickly and easily without the aid of compressed air.
The Exchange Tool Holders Type A are supplied with a smooth, ground bearing surface for turning tools. The Exchange Tool Holder Type K can serve as a holder for boring bars, as well as collets. Likewise suitably as a holder for taper-shank tools, when the hardened and ground KH taper sleeve is fitted in it. Drills etc. having a Morse taper can then be used with automatic feed.
Selection of tool post size
The size is selected according to the drive power of the lathe, the centre height and the cross slide width.
