Specific embodiment
The present invention is further illustrated below by way of specific embodiment.
The embodiment that the invention will now be described in detail with reference to the accompanying drawings.
A method of tandem mill memorial archway is carried out using isometry block and pedestal adjusts, including
Step 1,2 type selecting of isometry block:
Isometry block 2 is selected to use for setting up leveling ruler and inside micrometer is cooperated to use.Two kinds of specification isometry blocks 2 respectively choose processing
10-20 block adjusts needs convenient for multi-frame memorial archway pedestal simultaneously.The outer diameter that isometry block 2 is 0.01mm using preceding service precision grade
Each part thickness of miking monolithic isometry block 2 and muti-piece are superimposed thickness.Width is selected for setting up the isometry block 2 that leveling ruler uses
