Abstract: A special end cutting edge attached cutter for carbon fiber reinforced polymer/plastic with designable micro-tooth configuration, having an end cutting edge, a peripheral cutting edge with variation inverse helical groove, a peripheral cutting edge with constant inverse helical groove and a shank. Two parallel V-shaped chip pockets are designed on the end cutting edge of the cutter in two cutting edge directions which are symmetrical around a cutter axis as a center. The structure may enhance chip removal performance during high-speed milling of impenetrable slots and impenetrable windows, reduce wear of the end cutting edge, conduct configuration design for micro-teeth of the peripheral cutting edge, reduce the cutting thickness of the micro-tooth cutting edges, and effectively solve the problem of damage of the micro-tooth edges. A section of peripheral cutting edge with variation left-hand inverse helical flute angle is designed near the end cutting edge.

Abstract: A method for machining a drill with tilting blade slot structures for composite machining is provided. In the machining method, a face of the drill produces a downward component force for the inlet material to inhibit the inlet material from turning up; and a cutting edge inclination of an end surface at an outer turning point in a corner region of the drill is a positive value. The face and a flank are firstly partially ground in the corner region of the drill. The face at the outer turning point is ground with a grinding wheel to obtain two tilting blade slot structures. After grinding, a new face and a new cutting edge are obtained; and the cutting edge inclination on the end surface formed by the new cutting edge and a reference plane is a positive angle.

Abstract: Multi-adaptive fast loading attached air-cooled dust removal equipment is disclosed. The equipment is mainly composed of five parts: a spindle clamping mechanism, a link mechanism, a bearing connecting mechanism, an axial telescopic mechanism and a dust treatment mechanism. The equipment is connected with a tool holder through an axial connecting mechanism and installed on a machine tool. The axial telescopic mechanism forms a cavity with a processing surface, the gas flow generated by a negative pressure vacuum cleaner forms negative pressure in the cavity, and the telescopic mechanism is fixed to a machine tool spindle housing through the link mechanism to prevent the rotation of the spindle from driving the equipment to rotate and interfere with a workpiece, finally realizing rapid collection and treatment of chips.
