MITS' 3-axes-regulation machine can alternately perform the
two types of
milling operations, by simply switching between "incremental
milling" and
"absolute milling".
This is the MITS original technology.
Absolute milling
You can numerically control the height (depth) of Z axis by
CPU.
Although the flatness of the table and the deflection of the
processed material
might influence the depth, it is effective in limited processing
on the not deflective
material in limited area.
Incremental milling
Detecting the surface of the board, and keeping the depth
of the milling bit on
the uneven surface makes the processing unaffected to the
flatness of the table.
Particularly it is advantageous when processing with the Pointed-end
milling bit

Pressure foot
There are two types of pressure foot, contact method
and non-contact method.
Contact method
By holding the circuit board with the foot attached
to the processing head, the machine detects the surface
of the board.
The surface of the soft material can be damaged because
the pressure foot moves with touching the surface by
the force of approximately 1.4kg.
Non-contact method
Instead of holding down directly by the pressure foot,
the air blown out by the head hold and mill the board,
leading to process the surface without damaging.
(You need an air compressor.) |
