To sum up, existing fish-tail cutter exist working (machining) efficiency during Milling Process low and processing after dovetail rooved face thick Rugosity does not reach the problem of requirement.
Utility model content
This utility model be solve existing fish-tail cutter exist working (machining) efficiency during Milling Process low and processing after Dovetail groove surface roughness does not reach the problem of requirement, and then provides cooling fish-tail cutter in a kind of clamped cutting bit chip.
This utility model is to solve above-mentioned technical problem to adopt the technical scheme that:
Cooling fish-tail cutter in clamped cutting bit chip of the present utility model, described fish-tail cutter include cutter hub, handle of a knife, four Individual blade and four holding screws, one end of cutter hub and handle of a knife is fixedly mounted with and is integrated, and cutter hub is four toothings, on each tooth of cutter hub It is machined with a diamond shaped insert mounting groove, four blades are fixed on the diamond shaped insert mounting groove of cutter hub by four holding screws On, handle of a knife along its length on be machined with main Cooling Holes, cutter hub is uniformly machined with four points of Cooling Holes, each point Cooling Holes One end all connect with main Cooling Holes, the other end of each point Cooling Holes and corresponding diamond shaped insert mounting groove rake face are just to setting Put;Blade is 60 ° of diamond shaped insert, and blade is carbide blade, and diamond shaped insert mounting groove is consistent with insert shape to be arranged.
This utility model compared with prior art has the advantages that
In clamped cutting bit chip of the present utility model, cooling fish-tail cutter adopts 60 ° of rhombus cutter blades, machine clip-type formula, works as knife When pad wear is scrapped, the blade that only need to more renew, it is to avoid the entirety of cutter is scrapped, and cutter blade of the present utility model is hard Matter alloy material, substantially increases working (machining) efficiency, and working (machining) efficiency improves more than twice;The indexable use of blade of the present utility model Twice, blade has obtained optimum utilization;
This utility model adopts interior cooling structure, and cooling effect greatly promotes, and not only increases cutter life, and Further improve the suface processing quality of dovetail groove, surface roughness is improved to ra1.6 by former ra3.2.
