Synchronous rotary；
S2：Superfinishing fining-off, stock removal are made to the preceding rear neck end of work spindle using emery wheel on accurate cylindrical grinder
For 0.05mm, within 0.002mm, surface roughness is Ra0.02 μm for circularity and cylindricity error control after mill；
S3：Supporting rack is installed at the left and right roll neck of workpiece, while driving motor rotates workpiece, roll enters workspace
Domain carries out grinding to workpiece surface；
S4：Cooling processing is carried out to the surface of workpiece and roll using grinding fluid in process, then carries out workpiece
Spark-out processing, until stopping after the spark disappearance that roll and workpiece surface generate；
S5：After grinding, emery wheel to roll is pressed into, but is not fed, roll is polished, to further improve
Grinding surface quality.
Preferably, it is top using centre with endlong movement in the step S1, workpiece can be made freely to be extended after being heated, it is curved to reduce its
Song deformation.
Preferably, in the step S2, the linear velocity of emery wheel is 20--25m/s, and the length feed amount of emery wheel is 80--
400mm/min, the lateral feed of emery wheel is 0.003mm.
Preferably, in the step S3, the left and right roll neck junction of supporting rack and workpiece is lined with multi-disc butterfly spring, to subtract
The driving force at slow workpiece both ends.
Preferably, in the step S3, the linear velocity of roll is 20--30m/min, and the amount of feeding of roll is 100--
200mm/min。
Preferably, in the step S4, grinding fluid using magnetic roller type filter device and paper-tape filter device to grinding fluid into
Row double-filtration, the grinding fluid after filtering are precipitated in liquid case is ground, and are recycled.
Compared with prior art, the beneficial effects of the invention are as follows：Processing method of the present invention is simple, high precision machining, production
It is efficient, cooled down using grinding fluid to workpiece and roll, ensure that being smoothed out for processing, the convenient mounting and clamping of workpiece is protected
Demonstrate,prove the processing quality of workpiece.
Description of the drawings
Fig. 1 is flow process chart of the present invention.
Specific embodiment
Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other without making creative work
Embodiment belongs to the scope of protection of the invention.
Referring to Fig. 1, the present invention provides a kind of technical solution：A kind of method for grinding of roll grinder, this method it is specific
Step is as follows：
S1：The both ends of workpiece are processed into centre bore, and respectively installation one is top for two groups of central holes, makes workpiece and main shaft
