Hale machining is a technology where we use the spindle rotation as an additional axis (C axis). This allows precise positioning of the tool at a specific angle. Machining is carried out with the spindle rotation stopped. The hale byte removes material by scratching the workpiece.
Why should we do this? There are several applications including:
Using a boring bar for creating bigger bores than its own diameter
Using a diamond insert to make seal slots for housings
Using an engraving tool
Using specially shaped tools to create special contours

The example shows us three different paths using PCD tools:
