CNC Mills
If you have not already done so, download and familiarize yourself with the Users Guide, the Programming Guide, the Macro Instructions and the macro itself.

The fundamental motion of the tool is helical. The machine tool controller should be capable of helical interpolation, i.e. simultaneous 3-axis motion control. For mills without helical interpolation capability, a helix can be crudely approximated by combining circular interpolation with step-wise advancement of the tool in the Z-axis.

We offer a macro written in FANUC Macro B. This macro can be adapted to other controllers by knowledgeable programmers. Customized macros can be provided as well. Contact J.W. Done for details.

CNC Lathes
With lathes the helical motion is accomplished by offsetting the tool axis with respect to the axis of the hole, then advancing the tool in the Z-axis. Lathes with live tools are easiest to outfit with ORBITOOL deburring tools. Lathes without live tools can be fitted with moderately priced devices to run ORBITOOL deburring tools. The devices are either coolant- powered or driven by a motor and a flexible-shaft. Contact J.W. Done Co. for details.
