Situation two, using free abrasive grain lapping mode grind ferromagnetism material processed convexity taper roller when, it is described Second abrasive disk built-in magnetic structure, to increase quilt of the working face to the ferromagnetism material of the second abrasive disk helicla flute Processing convexity taper roller rotates generated sliding friction driving moment around own axes so that the quilt of the ferromagnetism material Convexity taper roller is processed around own axes continuous rotation not by the material of the working face of the first abrasive disk imploded arcs line trenches The matching of material and the material of the working face of the second abrasive disk helicla flute restricts.
The case where for magnetic texure is arranged inside the second abrasive disk of the abrasive disk external member in milling apparatus of the present invention Under processing is ground to the rolling surface of convexity taper roller, roller in milling apparatus of the present invention cycle disk external system also wraps Roller demagnetizer is included, roller demagnetizer is arranged in the roller transport system in roller disk outer circulation path or roller is defeated It send before system for by the processed convexity circle of the magnetized ferromagnetism material in magnetic field of the second abrasive disk built-in magnetic structure Roller demagnetization is bored, is only with previously described grinding method difference：
In step 3, while starting roller demagnetizer；
In step 6, initialization pressure is being applied to the processed convexity taper roller being distributed in the H of attrition process region Before power, magnetic texure enters working condition；It is being processed convexity taper roller to each of being distributed in the H of attrition process region While applying the initialization pressure of 0.5~2N, the magnetic field intensity of magnetic texure is adjusted so that the second abrasive disk helicla flute Working face rotates generated sliding friction driving moment more than the first grinding to being processed convexity taper roller around own axes The working face of disk imploded arcs line trenches rotates generated sliding-frictional resistance to being processed convexity taper roller around own axes Square makees continuous rotation movement to which driving is processed convexity taper roller around own axes；
In step 9, after the relative rotation speed for adjusting the first abrasive disk and the second abrasive disk to zero, magnetic texure switching To off working state, stop the operation of roller demagnetizer.
In first abrasive disk and the second abrasive disk for the first time before use, the processed convexity using identical geometric parameter is justified It bores roller and break-in is carried out to the working face of the first abrasive disk imploded arcs line trenches and the working face of the second abrasive disk helicla flute； Break-in method is identical as the processed grinding method of convexity taper roller；For step 8, to participating in the processed convexity of break-in Taper roller is inspected by random samples, when surface quality, form accuracy and the ruler of the processed convexity taper roller rolling surface inspected by random samples When very little consistency reaches technology requirement, the period of adjustment enters step nine；Otherwise, continue step 8.
Compared with prior art, the beneficial effects of the invention are as follows：
During attrition process, work in the working face of the first abrasive disk imploded arcs line trenches and the first abrasive disk helicla flute In each attrition process region H made of face is surrounded, be processed convexity taper roller rolling surface respectively with the first abrasive disk Line contact occurs for the working face one of the two sides of the working face of imploded arcs line trenches and the second abrasive disk helicla flute, is processed convexity The stub end ball basal plane or stub end rounded corner of taper roller or the working face of small head end rounded corner and the second abrasive disk helicla flute Two occur line contact, and convexity taper roller is processed under the friction-driven of the working face of the second abrasive disk helicla flute around itself axis Line rotates, and the working face for being processed convexity taper roller rolling surface and the first abrasive disk imploded arcs line trenches occurs to slide relatively It is dynamic, to realize the attrition process to being processed convexity taper roller rolling surface.The material removal of rolling surface and rolling table Face is directly related with the contact stress of imploded arcs line trenches working face, when larger-diameter processed convexity taper roller rolls table When the high point of face or processed convexity taper roller rolling surface is contacted with imploded arcs line trenches working face, rolling surface and indent The contact stress of camber line groove working face is larger, and the material removal amount of the rolling surface of contact position is larger；When the quilt of small diameter The low spot for processing convexity taper roller rolling surface or processed convexity taper roller rolling surface works with imploded arcs line trenches When face contacts, the contact stress of rolling surface and imploded arcs line trenches working face is smaller, and the material of the rolling surface of contact position is gone It is smaller except measuring.To realize that convexity taper roller rolling surface high point material removes more, low spot material removes less, it is relatively large in diameter Convexity taper roller rolling surface material remove more, the material of the smaller convexity taper roller rolling surface of diameter is gone less It removes.
Due to the opening Design of the first abrasive disk imploded arcs line trenches and the second abrasive disk helicla flute, deposited in attrition process It is fed along the circular arc of imploded arcs duct alveolobasilar line between the first abrasive disk and the second abrasive disk in processed convexity taper roller With via roller recycle disk external system collection, conveying, arrangement, feeding cycle, and via roller recycle disk external system when quilt The processing original order of convexity taper roller can be disturbed.
On the one hand, the opening Design of the first abrasive disk imploded arcs line trenches and the second abrasive disk helicla flute is adapted to very much High-volume convexity taper roller rolling surface finishes；On the other hand, that upsets when recycling disk external system via roller is processed Convexity taper roller order so that " convexity taper roller rolling surface high point material removes preceding feature more, low spot material is gone less It removes, the material much smaller convexity taper roller rolling surface of removal, diameter for the convexity taper roller rolling surface being relatively large in diameter Material remove less " entire processing batch can be diffused to, to which the convexity taper roller rolling surface of entire batch can be improved Form accuracy and dimensional uniformity；When another further aspect is due to attrition process, the first abrasive disk imploded arcs line trenches are ground with second Mill helicla flute has dozens of to as many as hundreds of confluces, i.e., has dozens of to hundreds of processed convexity circular cones to roll simultaneously Son participates in grinding, so as to improve the processing efficiency of convexity taper roller rolling surface, reduces processing cost.
