Specific embodiment
Intensity and extreme hardness when nickel base superalloy room temperature, belong to typical difficult-to-machine material.In usual machining
Under the conditions of, carbide-tipped milling cutter process velocity is extremely low, and usual cutting speed only has 30~60m/min, and processing efficiency is extremely low.This master
If will cause that cutting temperature is higher due to improving cutting speed, the Binder Phase cobalt in hard alloy ingredient can be lost, to lead
Cause cutter sharply wear, the service life decline to a great extent or even occur moment failure be not available situation.
However, if machining temperature is more than 800 DEG C, nickel-base high-temperature closes for nickel base superalloy roughing
Thermal softening can occur for metal working part surfacing, and the intensity and hardness of material sharply decline at this time, so that machining becomes light
Very much, processing efficiency dramatically improves, and cutter life can also greatly improve.
Roughing bulk ceramics milling cutter of the present invention, it is intended to by developing and being substituted using high temperature resistant Sialon ceramics current extensive
The sintered carbide tool material used, then bulk ceramics milling cutter optimization cutting edge roundness geometric parameter is matched, as core is thick, rake angle
With relief angle, chip pocket end face inclination angle, end clearance angle etc., increase the intensity of bulk ceramics milling cutter, so that with high cutting
When speed processes nickel base superalloy, whole Sialon ceramics milling cutter performance and precision keep stablizing, and on the other hand high cutting heat
Lead to workpiece surface material thermal softening, processing efficiency can be improved 10 times it is even higher, while the cutting tool service life also obtain into
Improve to one step.
The attribute for the Sialon ceramics of exploitation and existing cemented carbide material compares as shown in table 1.It can be seen that Sai Longtao
Porcelain fracture toughness is lower than hard alloy, but coefficient of friction only has the 1/4~1/5 of hard alloy, and ceramic milling cutter high speed can be improved
Chip removal performance when cutting reduces tool wear, improves cutter life.In addition, in terms of thermal characteristics, the thermal conductivity of Sialon ceramics
Extremely low, high cutting heat when high-speed cutting is difficult to be transmitted to Sialon ceramics cutter hub.And on the other hand, Sialon ceramics linear expansivity
It is lower, it is ensured that in high-speed and high-temperature cutting, Sialon ceramics milling cutter has better precision stability.Particularly, Sai Longtao
Porcelain can bear 1600 DEG C of high temperature of highest, far more than hard alloy material, thereby may be ensured that whole Sialon ceramics milling cutter in height
Cutter stable material quality when fast high-temperature machining, corresponding intensity and hardness are substantially unaffected, the progress that cutter can be relatively stable
High speed, high efficiency cuts nickel base superalloy.
In addition, compared with hard alloy material, since Sialon ceramics has lower chemical affinity, in High-speed machining nickel
When based high-temperature alloy, Sialon ceramics milling cutter is more difficult that oxidation occurs and diffusive wear, cutter life are higher.
