X-axis position detection section
In order to detect the X-axis position, photointerrupters (sensor) are installed
at the right and left stroke end limit.
NOTICE
The machine uses photointerrupters to detect an axis position.
The photointerrupter provides the reference for the axis origin
position. If the axis origin is displaced from its proper position, this
may lead to a failure of the machine. Therefore, if any associated
parts need to be replaced, contact your nearest DISCO Service
Office.

Rightward stroke
end limit
- Provides the reference position for
initialization, setup, cutting and
alignment operations.
- Detects the right end limit of the X-
axis maximum stroke.
- The reference (origin) position is
located at 9.5mm left of right soft-
end, which is fixed at 0.5mm left of
the right-end sensor.
Left-end sensor Leftward stroke
end limit
- Detects the left end limit of the X-
axis maximum stroke.

Y-axis section component names
The Y-axis section consists of the following components.
FRONT
Linear guide
Ball-bearing leadscrew
Y-axis base
Y2-axis AC servomotor
Y1-axis slider
Y2-axis slider
Y1-axis AC servomotor
Y-axis drive section mechanism
The Y-axis drive section is structured as follows:
Driving source Driven by AC servomotor with the aid of the ball-
bearing leadscrew.
Slide mechanism Employs a linear guide to assure smooth linear motion.

Y-axis position detection section
For Y-axis position detection, photointerrupters (sensor) are installed at the Y-
axis origin and front and rear stroke end limit.
NOTICE
The machine uses photointerrupters to detect an axis position.
The photointerrupter provides the reference for the axis origin
position. If the axis origin is displaced from its proper position, this
may lead to a failure of the machine. Therefore, if any associated
parts need to be replaced, contact your nearest DISCO Service
Office.
Sensor Name Sensor Position Operation
Rear end sensor Rear stroke end
limit
- Provides the reference position for
initialization, setup, cutting and
alignment operations of Y1-axis.
- The Y1-axis reference (origin)
position is located 20mm front from
the rear end sensor.
- Detects the rear end limit of the Y1-
axis maximum stroke.
Front end sensor Front stroke end
limit
- Provides the reference position for
initialization, setup, cutting and
alignment operations of Y2-axis.
- The Y2-axis reference (origin)
position is located 20mm rear from
the front-end sensor.
- Detects the front-end limit of the
Y2-axis maximum stroke.
Approach end
sensor
A sensor located
at Y1-axis front
end and a slit plate
at Y2-axis back
end, which are
used in a pair.
- Prevents collision between Y1- and
Y2-axis.
- Detects the approach threshold value
(30mm), which is the distance
between the blade center of spindle1
and spindle2.
