Integrated milling-rutter

Abstract

The invention is a kind of single-blade hobbing with sharp spiral blade and big row swarf slot, and it comprises colter arm, cutter body, the body is made up of side blade which has a ª‰spiral lifting angle, correspondent bottom blade, fore cutter face which is made up of spiral slots, several spiral aft cutter faces, the side blade and the bottom blade are all only one; the fore angle ª†is 25~30íÒ; the cross-sectional of fore blade face slot is a round arc, the volume of the slots accounts 35%~48%; the back cutter is made up of spiral main blade face, several assistant blade faces.

Description

technical field [0001] The invention relates to an integral milling cutter, especially an integral milling cutter for processing flexible materials. Background technique [0002] At present, the integral milling cutters produced and used at home and abroad are all double-edged or multi-edged. Due to the impact of the structure, the single-tooth chip removal space of this milling cutter is small, and the area of ​​the chip flute in the radial section accounts for 10-20% of the total area. The rake angle is also limited, generally less than 15°, which affects the sharpness of the cutting edge. When processing flexible materials such as TEFLON board, nylon resin, carbon fiber, and polymer composite materials, it is difficult to discharge chips, and the edge of the workpiece is prone to burrs, which cannot adapt Finishing needs; especially when processing flexible printed circuit boards, CD discs, and glasses made of resin, due to the small processing surface, aperture and hole ...

When processing flexible materials such as TEFLON board, nylon resin, carbon fiber, and polymer composite materials, it is difficult to discharge chips, and the edge of the workpiece is prone to burrs, which cannot adapt Finishing needs; especially when processing flexible printed circuit boards, CD discs, and glasses made of resin, due to the small processing surface, aperture and hole spacing, high dimensional accuracy and small surface roughness are required, and these materials are tear-resistant High cracking strength and poor thermal conductivity, the chips produced are long strips, which are easy to block and cause thermal deformation and splitting during processing
