Hale Machining

What is this technology?

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

Example 1

The example shows us three different paths using PCD tools:

Inside: Flat bite - 6 mm - F=1,000mm/min - machining time: 2 minutes 33 seconds

Middle: Turning bite R 0.8 mm - F=23,000 mm/min - machining time: 1 minute 55 seconds

Outside: Turning bite R 0.8 mm on a 80mm offset holder - F42,000 mm/min - machining time: 1 minute 25 seconds

Example 2

The example shows us three different paths using PCD tools:

Inside: Flat bite - 6 mm - F=25,000mm/min - machining time: 45 seconds

Middle: Turning bite R 0.4 mm - F=25,000 mm/min - machining time: 2 minute 36 seconds

Outside: Turning bite R 0.4 mm on a 160 mm offset holder  - F75,000 mm/min - machining time: 1 minute 36 seconds
