When we cut the diesel engine main shaft (Fig. 1), we must ensure the size of δ_(-0.015)~0mm. Therefore, we hope that the control tolerance of the boring tool adjustment is 0.002mm, so that the surface roughness reaches Rα0.4. Therefore, the precision and fine adjustment of the boring ba.......

The boring block is used for the hole with larger diameter. In order to save the tool material and prolong the service life of the tool, it is generally designed as a boring block with a card slot structure (semi-finished) (see the double-dotted line in the drawing).
