The controller is according to the processing aperture (R of input0) control fine tuning actuator by first gear, second gear, worm screw drive
Driving member rotation to drive ontology mobile and by the processing aperture adjustment of the boring cutter to preset theoretical pore (R1)；
Starting the processing unit (plant) rotates the boring cutter according to the revolving speed (n) of setting, and detector detects the knife bar and the blade phase
Radial displacement (x) for the central axis of the knife handle simultaneously feeds back to the controller；
Radial displacement (x) the control counter-driving element for the knife bar and the blade that the controller is fed back according to the detector, which drives, to be adjusted
Part is mobile to make the boring cutter reach the dynamic balance accuracy grade (G of setting0) tolerance；
The processing unit (plant) drives the boring cutter to carry out hole machined, aperture (R of the detector to preliminary processed hole to workpiece2) carry out
It measures and feeds back to the controller；
Aperture (the R that the controller feeds back the detector2) and preset theoretical pore (R1) compare to control fine tuning drive
The processing aperture that moving part adjusts the boring cutter carries out poor benefit, to process aperture (R needed for reaching0) tolerance；
The boring cutter continues to process according to the processing aperture after above-mentioned adjusting to the workpiece, is finally completed the hole machined to the workpiece.
10. as claim 9 uses the method in boring cutter processing hole, it is characterised in that: the controller is calculated because of the knife bar and is somebody's turn to do
Dynamic balance accuracy grade (the G that the radial displacement of blade generates1), the controller calculate dynamic balance accuracy grade [G] allowable=
G0* W*9550/n, wherein G0For the dynamic balance accuracy grade of setting, n is boring cutter revolving speed, and W is entire boring cutter quality, the controller
Calculate the dynamic balance accuracy grade G that need to be compensated2=[G]-G1, the controller is according to the dynamic balance accuracy grade (G that need to be compensated2)
Controlling the counter-driving element drives the regulating part is mobile to generate dynamic balance accuracy grade (G3) and offset the dynamic balancing essence that need to be compensated
Spend grade (G2), so that the boring cutter is reached the dynamic balance accuracy grade (G of demand0)。
