Based on above-mentioned purpose the utility model provides a pair of a multiple-cutting-edge milling cutter for glass processing, including PCD tool bit and handle of a knife, PCD tool bit fixed mounting in the tip of handle of a knife, the PCD tool bit has and is cylindric base member, the lateral wall axial of base member is provided with a plurality of cutting edge portions, the quantity of cutting edge portion is 50-100, the sword footpath of PCD tool bit is 2-20 mm.

As an alternative embodiment, the PCD bit and the shank are welded together.

As an optional implementation manner, two axial ends of the PCD cutter head respectively protrude outwards to form a first limiting portion and a second limiting portion, and the first limiting portion is fixedly connected with the end portion of the cutter handle.

As an optional implementation manner, the wall of the first limiting portion and the wall of the second limiting portion, which are connected to the side wall of the base body, are provided with an auxiliary blade portion integrally formed with the blade portion.

As an alternative embodiment, the width of the edge of the knife edge part is 0.01-0.02 mm.

As an optional embodiment, a blade groove is formed between two adjacent blade parts, and the depth of the blade groove is 0.08-0.015 mm.

From the above, can see out, the utility model provides a pair of a multiple-blade milling cutter for glass processing, through with the whole fixed mounting of PCD tool bit on the handle of a knife, then process out the sword type through spark erosion's mode on the PCD tool bit, rethread laser machine processes out a plurality of cutting edge portions, the quantity of cutting edge portion is 50-100, very big improvement the quantity of cutting edge, cutting ability is good, be difficult for tipping, thereby can be applied to 3D glass's processing, and because the improvement by a wide margin of cutting edge portion quantity, the flute that forms between the adjacent cutting edge portion can be used for processing the discharge of sweeps, be difficult for blockking up.
