1-6. Feed mechanism
[X-direction feeding]
1. When pulse motor X (1) operates, its motion is transmitted to the actuating gear (2), the idle gears (3) and (4), and
the X racks (5) and (6), that finally moves X-feed shaft holder L (7).
2. The X-feed guide shafts A (8) and B (9), which are connected to X-feed shaft holder L (7), move X-feed shaft
holder R (10).
3. The Y-feed guide shafts (11) and (12), which are attached to X-feed shaft holders L (7) and R (10), move the feed
bar (13) in the X direction.
[Y-direction feeding]
1. When pulse motor Y (14) rotates, its motion is transmitted to the actuating gear (15), the idle gear (16), timing
pulley A (17), that finally moves the Y-timing belt (18).
2. The Y-timing belt (18) is secured by the Y-driving shaft holder (19) and the belt holder (20), and that moves the Y
shaft (21).
3. The linear bush (23), which is fitted in the ball bearing (22), is fitted in the Y-guide shaft (24) to move the feed bar
(13) in the Y direction.
