Test conditions for high accuracy turret and single spindle coordinate drilling and boring machines with table of fixed height with vertical spindle. Testing of the accuracy - Portal type machines with moving table Ingestion-build-159183 It is conditional upon the1 Scope This part of ISO 3686 specifies, with reference to ISO 230 1, both geometric tests and machining tests on vertical spindle, portal type coordinate drilling and boring machines. It also specifies the applicable tolerances corresponding to the above mentioned tests. It should be noted that, besides drilling and boring operations, it may be possible to carry out light milling operations with these machines. However, this part of ISO 3686 does not
