TK6916A CNC horizontal boring machine
This machine is applies to the coarse and fine processing as well as drilling and reaming processing of surface and hole for large, heavy and over heavy complex components. It is suitable for general machinery manufacturing industry, especially for single pieces and small batch production of high precision and complex components. It has features of reducing manufacture number of process equipment and shortening production preparation period. The machine can complete the processing of milling, boring, turning, drilling and hole boring only in condition that workpiece is prepared on machine. This machine uses circular interpolation process (x, y coordinate axes) as well as small diameter milling cutter which can process any plane curve type surface. The adoption contouring control method for milling of inclined plane, square plane and big hole end plane narrowed operating space, improved production efficiency and relieve labor intensity. This machine is equipped with high precision rotary work table and square-edge milling head and other functional components which can complete the processing of pentahedron.
Main transmission system of TK6916E machine adopts variable frequency motor, which can realize stepless speed regulation. It also has 6 mechanical variable speed regulations by using handle for control. Reversible motion of spindle can be realized by the reversible motion of motor.
Cross feed of column (x coordinate axis), vertical feed of spindle box (y coordinate axis), axial feed of boring spindle (z coordinate axis) and vertical feed of square ram (W coordinate axis) can be realized by 4 Siemens manufactured AC servo motors driving ball screw to do motions of distance feed, minim feed and carry out function of stepless speed regulation. Maximum feed speed is taken as rapid moving speed. Reversible motions of all moving parts can be realized by reversible motion of motor
