Gundrilling | GO2cam Help Center

Deep drilling, also called gundrilling is a specific process to drill deep holes

Key Points for Deep Drill

Special options are applied, such as the management of feed and spindle speed at the start and end of machining and when intersecting other holes or cavities.

Mandatory rules to program a deep drilling operation:

A pre-drilling operation must be done in the hole,
the intersected holes and cavities must be machined before to be taken into consideration by the deep drilling.

Strategy Parameters

Dialog Area	Parameters
Depth	Depth/Reference	Depth
Depth	Retract
Leadin Strategy	Starting distance in reduced feed	Reduced Spindle Speed for lead in
	Coolant postponed	Stop for leadin control
	Spindle for entry	Feedrate for entry
Leadout Strategy	Distance before going through	Retract Distance(Peck)
	Spindle for retract	Feedrate for retract
	Final dwell	Reduced Spindle Speed for lead out
Speeds	Feedrate reduction coef	Reduced feedrate
Speeds	Spindle speed reduced	Feedrate in cavity
Intersections	Distance before intersection	Distance after intersection
Cavities	Distance after entering cavity	Mini size of cavity
Cavities	Distance before leaving cavity
