It is embedded in the cylinder groove of fixing groove and lower fixing groove composition, upper fixing groove and lower fixing groove diameter can be according to outside bearing blanks
Circular diameter setting, the bearing blank of the different model bearing machining seat different with lower fixing groove diameter using upper fixing groove.It is upper solid
Determine to be additionally provided with binding groove in slot and lower fixing groove, is provided with rubber strip in binding groove, further fixes blank, prevent blank again
Play in process.
Using the bearing machining seat, secured blank can be consolidated, one week uniform stressed of blank outer circle is fixed on solid
It, should compared to the mode that traditional processing seat is positioned using several fixed blocks in the cylinder groove for determining slot and lower fixing groove composition
Kind mode blank is not susceptible to play and displacement in process.The consistency of blanking inner hole processing can be greatly improved, is improved
Processing efficiency.
