Smithy GN1300 - Manual (Page 26)

B. Cross-Slide Handwheel - This handwheel moves the table toward and away from
the operator along the Y-Axis. Rotating the handwheel clockwise moves the table away
from the operator while moving it counterclockwise moves the table toward the operator.
C. Longitudinal Handwheel - This handwheel is located at the bottom left of the
carriage assembly. Manually rotating the handwheel clockwise will move the carriage
assembly along the X-Axis towards the tailstock end of the machine. Rotating the
handwheel counter clockwise will move the the carriage assembly towards the headstock
end of the machine.One revolution moves the assembly approximately .040”.
NOTE: This handwheel is for coarse movements only. Use the handwheel at the end of
the leadscrew for fine movement (0.001”)
D. Half-Nut Engagement Lever - This lever closes the half-nut on to the leadscrew.
When the half-nut is engaged, in the down position, the table assembly will be powered
to move right and left along the X-Axis leadscrew.
E. Longitudinal and Lateral Powerfeed Selector - This selector determines whether
the carriage will be powered to move along the X-Axis (longitudinal axis) or the Y-Axis
(lateral axis). When the lever is in the upper position the table will move along the Y-Axis.
When moved into the lower position, the table will move along the X-Axis. Center
position is neutral.
F. Threading Dial - The threading dial is used to coordinate consecutive cuts when
cutting threads. Restarting each cut from the same point on the dial ensures that each
cut follows the same path, leading to accurately machined threads.
G. Saddle - The saddle supports the cross-slide table and moves along the X-Axis of the
machine.
H. Apron - The apron houses the gear mechanism for the X and Y-Axis powerfeed.
! NOTICE !
The half-nut engagement lever is only engaged for rapid
travel or threading operations.
! NOTICE !
The threading dial can only be used when cutting inch
(SAE) threads.
