2. Brief Introduction:

2.1TK6920 Floor Type Boring and Milling Machine is a machine equipped with advanced techniques such as mechanics, electrics and hydraulics. Many key techniques are adopted: Hydrostatic guideway (constant flow), No back-lash rack-pinion drive system, ram feed auto compensation, etc. The machine is equipped with advanced CNC control system Siemens 840D or Fanuc 18i MB with FAGOR/HEIDENHAIN position sensor system, to make the machine in close-loop. All these well know and advance equipment make the machine with high rigidity, great efficient, easy operating and maintenance.To assure the accuracy and big torque at the same time, we improve the structure of ram to add another 4 sets (totally 8 piece INA bearings) to support.The machine has many self independent lubrication systems for different parts, especially for the boring head, to assure the effect of lubrication for the boring head.Except the casting of the machine, all the components are imported from German, Switzerland and America.The machine can complete boring, milling, drilling, reaming and tapping etc. machining procedures with once clamping. Optional equipped with right angle milling head, universal milling head, rotary table and other optional accessories, it can do heptahedron machining.
