8.1.5 Deep-hole drilling (CYCLE83)
Function
With the "Deep-hole drilling" cycle, the tool is inserted in the workpiece with the programmed
spindle speed and feedrate in several infeed steps until the depth Z1 is reached. The
following can be specified:
● Number of infeed steps constant or decreasing (via programmable degression factor)
● Chip breaking without lifting or swarth removal with tool retraction
● Feedrate factor for 1st infeed to reduce the feedrate or increase the feedrate (e.g. if a
hole has already be predrilled)
● Dwell times
● Depth in relation to drill shank of drill tip
