Cutters
For an optimal result, the cutter should be regularly checked
•
The cutting edges should be exempt of chocks and chips.
•
The lubrication holes should be clean up and the lubricant should flow to the tip of the cutter.
•
In case of deviation on the hole geometry, check the concentricity between the cutter body and
the edge as well as the concentricity between spindle and cutter : The deviation shall not
exceed some thousand of inches.
•
The countersinkings drilling need an adjustment of the "Belleville washer" 93 440 599 thrust.
Generally the repeatability of the countersinking depth is better when the thrust is low. Consi-
dering the amount of parameters, we recommend to adjust the thrust according the Apex Tool
Group specification or to perform a drilling test to determine the retract signal linked to the dril-
ling thrust end of Work feed cycle. Then screw 90 810 996 the but 1/16 rev to increase the
thrust in place.
