Problems solved by technology

[0002] At present, the PCB industry usually uses double-edged and multi-edged milling cutters to process flexible boards, flexible boards, PTFE, PP sheets and other soft board materials. Due to the limitation of the chip removal space and the sharpness of the cutting edge, chip removal is easy to occur during processing. Bad problems, resulting in poor roughness of the processed surface, and the phenomenon of knife breaking, and also the problem of board edge burrs, which affects the performance

Abstract

The invention discloses a single-blade milling cutter applicable to the technical field of milling cutter structures. The single-blade milling cutter comprises a cutter handle and a cutter body connected to one end of the cutter handle. The cutter body is provided with a spiral cutting blade, a chip discharging groove and a main cutting blade. The chip discharging groove and the spiral cutting blade are spirally arranged around the axis of the cutter body in the direction from the front end of the cutter body to the cutter handle. The spiral cutting blade and the chip discharging groove are same in the spiral angle. The main cutting blade is arranged at the front end of the cutter body and is adjacent to the chip discharging groove. The cutting edge of the main cutting blade is of an arc concave structure, and the main cutting edge is provided with an arc-shaped relief angle. Through the single-blade milling cutter provided by the invention, the overall stiffness strength of the milling cutter and the sharpness of the cutting edges can be improved, and meanwhile, the effect that chips are discharged smoothly is ensured.

Description

technical field [0001] The invention belongs to the technical field of milling cutter structures, in particular to a single-edged milling cutter. Background technique [0002] At present, the PCB industry usually uses double-edged and multi-edged milling cutters to process flexible board materials such as flexible boards, flexible boards, PTFE, and PP sheets. Due to the limitation of chip removal space and the sharpness of cutting edges, chip removal is easy to occur during processing. Bad problem, resulting in poor surface roughness, as well as the phenomenon of knife breakage, and the problem of burrs on the edge of the board, which affects the performance. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to overcome the above-mentioned deficiencies of the prior art, and provide a single-edged milling cutter, which can improve the overall rigidity of the milling cutter and the sharpness of the cutting edge, while ensuring the smooth discharge of ...
