Fruit is good；It is convenient for the discharge of scrap by chip space, guarantees processing quality, helps to improve the technologies such as cutting-tool's used life
Effect, elaboration as detailed below.
To achieve the above object, the utility model provides following technical scheme:
A kind of interior cooled Polycrystalline diamond reamer provided by the utility model, including knife handle, the knife handle bottom end peace
Equipped with knife bar, it is provided with cutting edge and chip space on the outside of the knife bar, the cutting edge and the chip space are interspersed；
The knife handle and the knife bar are internally provided with liquid injection hole, and the liquid injection hole is blind hole；It is set inside the chip space
It is equipped with fluid hole, the fluid hole is connected with the liquid injection hole.
Using a kind of above-mentioned interior cooled Polycrystalline diamond reamer, when use device, to the liquid injection hole inside inject it is cold
Coolant liquid is infused in the cutting edge side by the fluid hole, is cooled down using coolant liquid to cutting edge by but liquid, by
It is blind hole in the liquid injection hole, can guarantees that coolant liquid is fully injected into the cooling in the cutting edge side, to the cutting edge
Effect is good, can guarantee machined surface quality；Hole wall is processed by the cutting edge, the scrap of generation enters the row
It considers to be worth doing inside slot, with the injection of coolant liquid, coolant liquid can be discharged along the chip space, while by scrap out of described chip space
Portion releases, and chip removal effect is good, helps to ensure that machined surface quality, improves cutting-tool's used life.
Preferably, the chip space uses herringbone structure.
Preferably, the chip space is along the extending direction of the cutting edge, depth is gradually increased from top to bottom.
Preferably, the top of the knife bar is provided with crumb loading groove, the chip space is connected with the crumb loading groove.
Preferably, the fluid hole is uniformly distributed at least provided with three, and along the extending direction of the cutting edge.
Preferably, the section of fluid hole structure in an inverted cone.
Beneficial effect is: 1, coolant liquid can be injected to the cutting edge side by the liquid injection hole and the fluid hole
Face cools down the cutting edge, and the liquid injection hole is blind hole, can guarantee that coolant liquid is fully injected into the cutting edge side
Face, good cooling results；
2, it is convenient for the discharge of scrap by the chip space, guarantees processing quality, helps to improve the use of cutter
Service life.
Detailed description of the invention
