The distance which the boring bar is fed in at 70% of the original feed rate and milling spindle speed to finish the hole bottom The feed rate is reduced to 70% of the original value before the hole bottom is reached. Note : Not valid if the setting for the roughness (RGH) of the boring (tool sequence) is 1.

Machine-specific. This parameter list is specific to the Mazak INTEGREX e-670H / e-670H-S with the MAZATROL SmoothX control (manual HA64HA0035E). Other Mazak models and control generations use different addresses, ranges and meanings — verify on your own control before changing anything.
