I. The machine is a special machine designed and produced by our company specially for users in accordance with market requirements on the basis of general deep hole drilling and boring machine. The machine tool absorbs the advanced design and manufacturing technology, adopts CAD Optimization design method, carries out the latest national accuracy standard and the rigidity standard of our factory, configures advanced functional parts, and has the characteristics of long-term rigidity of the bed, safe and reliable movement, long service life and high processing efficiency.
The machine can complete the drilling process of the inner hole. During machining, the workpiece is fixed, the cutter rotates and feeds, the cutting fluid enters the cutting area through the oil feeder, cools and lubricates the cutting area and takes away the chips. The chips and coolant are discharged backward through the drill pipe to the rear chip hopper and then into the chip conveyor. BTA bit is used for drilling, and the processing method of internal chip removal is adopted.
