CNC heavy duty floor type boring machine
*TK69 series machine is widely absorbed the advantages of the china and abroad similar machine tools, well-designed china first class heavy duty CNC floor type milling and boring machine. Equipped with precision CNC rotary worktable and functional attachment, one time load can be for milling, boring, drilling, threading, grooves and consecutive five face machining. Suitable for metallurgy, mining, energy generation (fire, water, wind) ship building, steel, transport large equipment machining.
Customers can choose the optional tool magazine and different CNC rotary worktable, angle milling head, special milling head and face plate for different needs.
The machine features
-The main parts select the high quality casting iron, high intension and high rigidity.
-The machine main transmission (mechanical three step & step less in each step) and feed transmission wide range speed , suitable for all kinds tools and material.
-The main spindle bearing adopt imported angular contact ball bearing, high spindle rotation accuracy, good stability.
-The column (X axis) adopt mechanical or electrical anti backlash double gear rack transmission. Spindle box plate (Y axis), ram (Z axis) and boring tools (W axis) feed by the ball screw transmission power. All feeds shaft realize the zero clearance.
-Ram is made by nodular casting iron. Ram support is in the fully enclosed square hole. The whole spindle box can be one over all pieces and good rigidity.
-Adopt unique spindle box plate couple stress compensation and electric hydraulic ram compensation double technologies to realize ram bowed head compensation.
-Guideway are "one cavity one pump" closed constant hydrostatic guideway with good rigidity, good anti vibration characteristics.
-Equipped with thermostatic system to prevent thermal deformation.
-Equipped with independent hydraulic lifting enclosed work station, in addition to lift up and down, also can be moved on ram direction, easy to operate, to avoid the worker walking to affect the machine accuracy.
-Equipped with independent automatic chip convey and trolley.
-Choose the optional tool magazine can be a mill boring machining center.
-Using Siemens 840 sl CNC system and Austrian AMO scale detection
