Blind hole machining technology

The invention belongs to the technical field of machining and particularly relates to a blind hole machining technology. The blind hole machining technology comprises the following steps that 1, preparation is conducted, specifically, a drilling tool and a rack with an electromagnet are prepared, and a chip attracting pipe capable of automatically attracting wood chips through the electromagnet isslidably connected into the drilling tool; 2, drilling is conducted, specifically, a workpiece is fixed to the electromagnet, the drilling tool and the chip attracting pipe continuously downwards move to form a blind hole while the drilling tool and the chip attracting pipe rotate, the rotating speed of the drilling tool is 1150-1300 r/min, and the falling speed of the drilling tool is 15-20 mm/min; 3, chip attracting is conducted, specifically, the electromagnet is started, the chip attracting pipe is fixed, meanwhile, in the upward moving process of the drilling tool, the wood chips in theblind hole are automatically attracted through the chip attracting pipe, and the working current of the electromagnet is 1000-1300 A; 4, discharging is conducted, specifically, the electromagnet is stopped, the chip attracting pipe automatically upwards moves, and after the chip attracting pipe moves out of the blind hole, the workpiece is taken down; and 5, chip discharging is conducted, specifically, in the process of continuous upward moving of the chip attracting pipe, the wood chips in the chip attracting pipe are automatically discharged. According to the scheme, the wood chips in the blind hole can be conveniently cleared away.
