Description
Technical field
This utility model is related to cutting tool design field, specially a kind of Assembled rotary cutting tool.
Background technology
Cutting tool is indispensable important tool in machining, especially commonly uses rotation in drilling machine or boring machine
Cutting tool, but existing rotary cutting tool is primarily present two problems：One is existing cutter when being cut
When mainly being cut using outer rim, and using complex cutting tool to process, such cutter is generally pointed to the area at center cutter position
Domain cutting power is poor, and easily because blade discontinuity fractures, and two is the easy wear out failure of cutting edge of cutter, if
Change that whole cutter is clearly uneconomic, it has been mainly doing for existing cutter production that therefore cutting edge is separated with knife bar
Method, but most of cutter of existing setting also only has cutting edge change, and the cutter in practice for labyrinth, especially
Be multi-knife-head cutter long-time use after, once knife bar connection blade position distortions just necessary integral replacing, therefore cost according to
So expensive, if it is possible to invent a kind of knockdown cutter and just can solve the problem that problems, we provide a kind of combination for this
Formula rotary cutting tool.
