TK2280/TK2180 series CNC deep hole drilling and boring machine

This machine tool is a special machine tool for deep hole processing, which can mainly complete the drilling, boring, expanding, rolling and nesting processing of inner holes of large-diameter cylindrical heavy parts. During processing, the workpiece rotates at low speed, the tool rotates at high speed and feeds and cuts; in addition to processing through holes, stepped holes and blind holes can also be processed. This machine tool can flexibly choose the processing method according to the actual needs, and has a wide range of applications.

TK2280/TK2180 series CNC deep hole drilling and boring machine

When the machine tool is drilling, the BTA internal chip removal process is adopted. The oil feeder supplies high-pressure cutting fluid and wraps the chips, which are discharged from the inner hole of the drill pipe tail. When boring, the boring process is adopted. The cutting fluid enters the cutting area through the oil feeder (small diameter) or the tail of the boring bar (large diameter), cools and lubricates the cutting area, and discharges the cutting fluid forward (the head end of the bed) to take away the chips. When nesting, the process of external chip removal is adopted, which needs to be equipped with special nesting tools, tool holders and special fixtures.

T2180 deep hole drilling and boring machine is equipped with a drill pipe box, which can realize double rotation of workpiece and tool, and can also be single-acted to meet the needs of processing technology in different situations; under the condition of fully reducing the speed of workpiece (not suitable for high-speed rotating workpiece), it can effectively Satisfy the processing efficiency and improve the processing accuracy and quality.

The machine tool is clamped by a heavy-duty four-jaw chuck at the head of the bed, supported by the center frame, and the oil dispenser hydraulically presses the workpiece. The oil feeder adopts the main shaft structure, the load-bearing performance is greatly improved, and the rotation accuracy is higher. The machine bed has strong rigidity, high wear resistance and good precision retention. The tool feed adopts AC servo drive system to realize stepless speed regulation. The headstock is driven by a DC motor with stepless speed regulation; the drill pipe box is driven by a high-power motor with gear shifting for speed regulation. Hydraulic device is used for the tightening of the oil feeder and the clamping of the workpiece. All the work is displayed on the instrument, and the clamping of the workpiece and the operation are safe, fast and stable. The machine tool is controlled by PLC and provides a man-machine interface, which fully reflects the pleasantness of the operation of the machine tool.
