Ball turning device hapfo® KPF-400

The hand rest or tool rest lower part of the PERFORMER 400-FU can be used. Optionally for other makes, the ball turning attachment KPF-400 can also be ordered with hand rest lower part. Please select!

The ball turning attachment KPF-400 has been specially developed for the hapfo PERFORMER 400-FU (center height 402 mm) and adapted to the dimensions and forces of this machine. It can be used to quickly and effectively produce balls up to 650 mm in diameter. Mounted on a solid cast iron rotary table, the existing hand rest base can be slid on. The included trapezoidal spindle with handwheel can be fed very sensitively. Alternatively, the KPF-400 can be supplied as a complete unit and adapted to other woodturning machines. The KPF-400 is equipped with two cutting systems. One side of the tool holder holds a carbide insert, with which the complete ball is pre-machined. This eliminates the otherwise tedious regrinding of the tools. The diamond shape and the large cutting edge radius of the insert effectively prevent "hooking" into the workpiece. For fine machining, an HSS cup tool is available on the same tool holder. This is simply exchanged for the insert by turning the tool holder 180°.

The tool holder is designed in such a way that both tools are always at the same height at the tip. To prevent hooking in the workpiece, a chip depth limiting screw is used with the HSS cup steel .

Maximum ball diameter approx. 650 mm
