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.
