Have the most progressive.Cutter of the present invention, when entering small-bore, can be at contraction state and enters, i.e. flexible by turning clockwise
The adjusting nut of cutter right-hand member, makes adjusting rod and adjustment seat pull the small boss of front tool rest right-hand member, makes front tool rest and rear tool rest
Center is horizontal enters processing workpiece.After the cutter head of Telescopic cutter enters in workpiece, by rotary extension car counterclockwise
The adjusting nut of cutter right-hand member, before making adjusting rod and adjustment seat promote, the small boss of tool rest right-hand member, makes in front tool rest and rear tool rest
After the heart is at an angle, the internal bore profile of process larger sized, machine and can recover to contraction state, facilitating cutter to remove
Go out.
