1-2 Operation Theory (Mounting Mechanism)
The machine has 12 mounting heads, each head being equipped with 5 nozzles. Each head
carries out the following operations from 1 to 12 simultaneously at each station (the station ad-
vances two steps during one rotation of the indexing unit) (rotary method).

1-3 Operation Mode of the Double Feeder Stage
In order to flexibly respond to your various types of production, the CM88C provides the following 3
types of production mode. It is possible to exchange the feeder in all modes during running the
machine.
a) Exchange mode
This mode is effective when the parts for mounting is less than 70 types of component.
When the components on the B stage run out, production is automatically continued on the Astage.
Producing of A type
b) Priority exchange mode
This is effective when wishing to use one stage by priority in exchange mode.
When the specified stage is available, this stage is used by priority. (After the board being pro-
duced currently has been mounted, the stage is switched over automatically.
A Stage Priority Specified
∗ Set them at “Option configuration” in the machine parameters.
c) Spare mode
This mode is effective for the changeover (change of board to produce).
(But number of parts placed on the board is less than 70.)
