Description

A kind of grinding attachment of boron carbide air-bearing
Technical field
The present invention relates to precise machine machining field, more particularly to a kind of grinding attachment of boron carbide air-bearing.
Background technology
Boron carbide air-bearing part is hollow cylindrical structure, and material is boron carbide ceramics, its bearing air supporting working face It is endoporus and two end faces, because the ultrahigh hardness of boron carbide material is only second to diamond and cubic boron nitride, main processing side Method is to be ground using diamond abrasive and attrition process, and because boron carbide material has the low i.e. fragility of Fracture Toughness big The characteristics of, less cutting data must be used in grinding, therefore processing efficiency is low.
The grinding process method of the usual boron carbide air-bearing is:Directly filled with the chuck of grinding machine or using collet Cylindrical, then grinding endoporus and the both ends of the surface of card boron carbide air-bearing, due to grinding other end or remove part and survey Axial dimension is measured, it is necessary to multiple clamping again, but the repetitive positioning accuracy of this installation way is not high, so being difficult to by mill The precision index for reaching requirements above is cut, it is necessary to reach precision by hand lapping again.
And boron carbide air-bearing part during endoporus and cross grinding because skive can not be carried out Line is repaired, it is necessary to repaired again after skive is dismantled from grinding machine, and skive is attached into grinding machine again Afterwards, it can cause boron carbide material bearing parts machining accuracy and surface roughness all do not reach to use to want due to alignment error Ask, influence part processing precision and efficiency.
The content of the invention
The invention aims to solve shortcoming present in prior art, such as:Traditional clamping positioning method is carried out The grinding of boron carbide air-bearing inner bore of part and both ends of the surface, is repeatedly loaded and unloaded and finishing skive, it is difficult to reach institute It is required that size and the accuracy of form and position and the grinding attachment of a kind of boron carbide air-bearing that proposes.
To achieve these goals, present invention employs following technical scheme:
