Surface speed reduction ratio at cutting end of a very-deep-hole drilling cycle/decremental very-deep-hole machining cycle
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.
What it does
Surface speed reduction ratio at cutting end of a very-deep-hole drilling cycle (through hole)
Set the surface speed reduction ratio at cutting end of a very-deep-hole drilling cycle (through hole) during the point machining. If the surface speed during drilling is S, the surface speed S’ at cutting end is calculated using the following calculation expression: S’ = S × D59/100 The surface speed is reduced to S’ by “speed reduction distance immediately before the hole bottom” (hb specified in the program).
