  • Three dimensional linear processing machine and a method of composing and controlling machining program in the three dimensional linear processing machine
    Patent number: 6522941
    Abstract: The chuck 10, for positioning and holding a pipe at any rotational angle position around the axial center, is provided with the three dimensional linear processing machine. When the machining program PRO is composed, a plurality of the shape patterns KPT classified machining modes concerning pipes by machining shape is displayed on the display 23. Furthermore, dimensional data item concerning selected shape pattern is displayed on the display 23. Then, the machining program PRO is composed on the basis of the input code parameter CP and the selected shape pattern KPT. Besides, shift quantity TMz and TMy are measured when the pipe to be machined is installed on the chuck 10, and on the basis of this, the machining program PRO is amended and executed.

  • Machining method for the use of a complex machining machine tool
    Patent number: 5191817
    Abstract: A complex machine tool has a single frame having a chip collecting space at a center portion thereof, first and second spindle stocks on the frame, relatively free to move and drive in a Z axis direction and holding the chip collecting space therebetween, workpiece spindles on the spindle stocks free to rotate and drive and facing each other, and tool rests. The tool rests have turrets and can assume various kinds of movement. Complicated and varied types of machining can be performed combining the rotation control of the workpiece spindles and the spindle stocks.
