One of the most novel EDAF innovations is the use
of built-in Smart Logic as part of Makino’s Hyper-i
Control. Smart Logic provides a consistent and
smooth fl ow rate to prevent agitation of work tank
fl uid debris – see Figure 2.

In addition to the enhancements in tank circulation The new fi lters on the EDAF Series utilize a thin

improvement in machining environment cleanliness.
Surface fi nishes are more consistent and free from
“pin-holing.” Figure 5 shows a highly magnifi ed
surface fi nish registering 1 on the VDI scale.
The surface consistency is clearly evident.
The cleaner machining environment also supports
improvement in corner edge quality.

cutting to determine edge quality. In Hardened D2
tool steel, the EDAF Series machine was able to
achieve a clean, consistent edge with only 0.0003”
corner radius.

The fi lter canisters and fi lters have been improved
as well. The fi lter canisters have been redesigned to
simplify and streamline the fi lter changing process.
There are only two parts to remove to change fi lters.
