The surface quality of workpiece is determined by corner radius size, cutting-in and the amount of feeding.Uniformity, round and smooth blade subtracts
Cutter peeling is lacked（The fritter work in-process dialysis of coated cutting tool and matrix material）Tendency.It is most of to pass through chemical gaseous phase
The cutter of (CVD) process coating is deposited, the reinforcing cutting edge for having circle.Reinforcing is prepared for coating, especially to thicker
CVD coatings, passivation make coating material have enough mating surfaces.
It is always metal cutting development that stock-removing efficiency, cutter life are improved in machining and reduces manufacturing cost
Major subjects.In recent years, the good and in light weight new material of many high-strength hots hardness is used in Design of Industrial Product, such as
High temperature alloy, titanium alloy and composite etc..The common processing characteristic of these new materials is that stock-removing efficiency is low, cutter life
It is short.When being processed with hard alloy cutter, the knife of use cuts only more than ten meters per minute of speed, and cutter life also only has 30 minutes left sides
The right side, crudy can not also be guaranteed（Roughness, dimensional accuracy and form and position tolerance）.It is also more preferable, more effective in order to research and develop
Cutter.Substantial amounts of work has been done to cutter structure, material and raising cutter properties both at home and abroad in the past 20 years, and achieved very
More scientific achievements.But some achievements are not satisfactory in the practical application effect of factory.To be necessary to grind on the basis of original
Hair, innovation have more advanced cutter, while research and develop can make processing efficiency raising, the supporting skill of the metal cutting of tool bit life
Art.It facts have proved that its life-span of the cutter through transpassivation, quality, efficiency have different degrees of raising wherein tool bit life most
To be obvious.
The content of the invention
In view of the above the shortcomings that prior art, it can extend cutter it is an object of the invention to provide one kind and use the longevity
Life, improve the cutting tool dulling technique of cutter quality and efficiency.
In order to achieve the above objects and other related objects, the present invention provides a kind of cutting tool dulling technique, and it includes following step
Suddenly：
1）At least one to be incited somebody to action to be fixed on a rotating device cutter, the rotating device can rotate with cutter around a central shaft,
Simultaneously can be with cutter rotation itself；
2）Fixed cutter on the spinning device is placed in a container, grinding agent is placed with the container, by rotating dress
Put and drive the cutter rotation and revolution, cutter is passivated；
3）Cutting tool dulling 5-20 minutes, you can complete passivation.
Preferably, the R values of the cutting edge roundness are less than 0.005mm.
Preferably, also doped with walnut powder in the container.
As described above, the cutting tool dulling technique of the present invention has the advantages that：, can be effective using the passivation technology
The cutting edge to cutter be passivated, extend cutting-tool's used life, the operating efficiency of cutter is higher.
