Okuma M-codes (turning): reference table
Complete reference table of Okuma M-codes for lathes: more than 1,100 codes from M00 to M1255 with descriptions and standard/option designation.
Okuma’s OSP control uses M-codes (miscellaneous functions) to switch machine functions such as the spindle, coolant, chuck, tailstock, and tool change. This reference lists the M-codes for Okuma lathes from M00 to M1255.
Machine-dependent assignment
The “Standard/Option” column shows whether a code is part of the base configuration or requires an optional machine function. Which codes are actually available depends on the model and equipment. When in doubt, your machine’s documentation applies.
