Feed and drill speed
The Feed – penetration speed of a drill unit is provided by a ball circulation spindle
which is controlled by a servo motor.
The speed of the drill spindle is controlled directly from the computer program,
dependant on the entered drill diameter according to the list below.
The rotation speed of a drill spindle is determined by a frequency controlled drill
motor. The drill motor is controlled digitally from the computer program by means of a
frequency regulator.
The default factory settings for Speed and Feed Penetration are set as follows:
Drill diameter Feed/ Penetration Feed Rate Speed
mm mm/min mm/rev RPM M/min

The above data to be used when drilling Steel 37A Grade Material (<30mm deep),
HSS Endfeed drill with air/oil microlubricated cooling and KALTENBACH grinding
method.
For harder materials (50 Grades)or >30 mm deep, reduce the drilling speed (RPM) but
maintain the FEED RATE (mm/rev).
