lightweight nonmetallic materials digital control processing chip removal device described in the utility model, it is characterized in that: comprise lathe, the air-blowing blowing device, negative pressure air-suction device and scrap collecting box, on the knife bar of described machine tool chief axis, cutter blade is installed, described cutter blade comprises discoidal cutter blade, be arranged on sawtooth and the through hole that is arranged on the cutter blade center on the cutter blade circumference, on described cutter blade between adjacent sawtooth, chip pocket is set, on described sawtooth, blade is installed, described blade is met to the side of cutting direction and bottom surface side blade and bottom surface blade is set respectively, the inner setting with the annular of through hole concentric of described cutter blade blown the bits air flue, arrange and blow the bits notch on described chip pocket, described annular blow bits air flue respectively with the inlet channel that is arranged on cutter blade and blow bits notch be communicated with, the through hole that the bottom surface of described cutter blade arranges two-layer annular table terrace ，Yu center forms suction bits passage jointly, the through hole at described cutter blade center is communicated with described negative pressure air-suction device, the air inlet of described inlet channel is connected with described air-blowing blowing device pipeline.
The described bits notch that blows is arranged on chip pocket near meeting to the position of the blade of cutting direction, and describedly blows wind that the bits notch blows out and can cover the chip surface of whole blade.
The air inlet of described inlet channel is arranged on the end face of cutter blade.
The side blade of described blade and the anterior angle of bottom surface blade all are set to 45 degree.
During use, the cutter blade through hole is arranged on the knife bar of Digit Control Machine Tool, pass through again to connect the pipeline communication of main shaft to negative pressure air-suction device, and the air inlet of the inlet channel of cutter blade is communicated with the air-blowing blowing device, form separate suction bits passage and blow the bits passage, in to lightweight nonmetallic materials machining, the smear metal that produces can the very first time be arranged on offer on cutter blade outer surface chip pocket blow the bits notch in the air-flow that blows out blow open near blade, then inhaled the negative-pressure air-flow of considering the passage generation to be worth doing by cutterhead again and take away, deposit in the scrap collecting box.
The beneficial effects of the utility model are: (1) the cutter blade physical arrangement is strengthened chip removal ability and other encloses the mode of putting the air blowing chip removal outside by changing compared to traditional, pressure-vaccum is in conjunction with having chip removal effect more thoroughly, and adopted uniquely the pressure-vaccum gas circuit to be integrated in form on cutter blade and main shaft in this chip removal mode, simple for structure, be easy to control; (2) main shaft and cutter blade knife bar inner high speed flow and the air-flow that blows out can be arranged loose heat in metal cutting well, can effectively improve the harmful effect that high temperature brings to surface quality and the cutter itself of processing work; While (3) adopting chip removal mode described in the utility model, cutter hub, the knife bar of manufacturing supporting cutter blade out are the hollow-core construction that is provided with air flue, and overall structure is simple, and quality is light, are convenient to control, and be little to the potential injury of main shaft.
