TRANSMISSION
)
Headstock spindle speed change：
The motor power is transferred to Headstock axle I through V-belts and then to
headstock main spindle through sliding gears on axle I and axle V, so the main
spindle gets 12 kinds of different speeds.
)
Feeding speed change and thread tooling：
The main spindle works on the gears on axle III and IV through feeding gears, the
different meshing of sliding gears on axle III achieves forward and reverse
rotation.
。
Through a set of final reduction gear and change gears A, B, C to drive
the input axle in feeding box, then through complex gears on second motion shaft,
to make the output axle achieve two different rotation directions and 15 different
