Problems solved by technology

[0002] Existing milling cutters have strong versatility, long chip removal ability and short service life when milling workpieces, and because the waste chips generated during processing cannot be cut off, it often causes troubles and even affects the processing and maintenance of workpieces. Personal safety, generally during the chip cutting process, a lot of heat will be generated. Due to the high cutting temperature at the tip of the existing milling cutter, it is too late to cool down, which will easily cause the milling cutter to wear larger and faster, which not only affects the machining accuracy of the workpiece, but also affect its lifespan

Abstract

The invention relates to a double edge milling cutter comprising a handle and edges, wherein the handle is provided with main spiral grooves positioned between the two edges, the number of the main spiral grooves is two, the main spiral grooves are oppositely arranged on both sides of the edges, one side of the edge is provided with a vice spiral groove, both ends of the vice spiral groove are connected with the two main spiral grooves, the end part of the handle is provided with a clamping groove, the clamping groove is provided with a cooling hole, a lubrication channel is arranged in the handle, one end of the lubrication channel is connected with the cooling hole, the other end of the lubrication channel is provided with a branch channel connected to the edges, a chip breaking block fixed on the handle is arranged below the clamping groove, and the end face of the chip breaking block is an arc shape. The double edge milling cutter has the advantages of simple structure, long service life, and automatic chip breaking and the like.

Description

technical field [0001] The invention relates to the technical field of milling cutters, in particular to a double-edged milling cutter. Background technique [0002] Existing milling cutters have strong versatility, long chip removal ability and short service life when milling workpieces, and because the waste chips generated during processing cannot be cut off, it often causes troubles and even affects the processing and maintenance of workpieces. Personal safety, generally during the chip cutting process, a lot of heat will be generated. Due to the high cutting temperature at the tip of the existing milling cutter, it is too late to cool down, which will easily cause the milling cutter to wear larger and faster, which not only affects the machining accuracy of the workpiece, but also affect its lifespan. Contents of the invention [0003] In view of the above problems, the purpose of the present invention is to provide a double-edged milling cutter with simple structure...
