Embodiment Construction
[0018] Taking the grinding and polishing of measuring cone mandrel taper 1:15000 as an example, the specific implementation of the invention is described.
[0019] The oil stone guide rail 1 and the precision oil stone for grinding are ground through three planes to obtain higher plane precision. Check the flatness of the oilstone guide rail with a long flat crystal. The direction Moiré fringes on the length of the guide rail should be close to parallel and symmetrically distributed in the width direction. Regardless of the sag area, the coverage area of two moiré fringes is not less than 50% of the total area of the guide rail and one moiré fringe is about 0.29 μm.
[0020] Firstly, the center hole of the taper mandrel 4 to be processed is repaired to improve the precision of the rotary reference. Then pass the cone mandrel into the hole of the oilstone guide rail 1, and support the cone mandrel with a 60°elastic tip. Adjust the screw A21 on the bearing seat to make the...
