Vertical Spindle Manual Feed Operation - Sharp VH3 Mill Operations Manual & Parts List

3-7 Vertical spindle manual feed operation

There are two types of manual vertical spindle adjustment, namely, adjustment by hand
wheel (Fig.11 (1)) and rapid adjustment by the main vertical spindle adjustment lever (Fig.12
(4)).
For general milling, the hand wheel for the vertical spindle adjustment should be used.
The handle wheel for the vertical spindle adjustment is providing with a scale collar (Fig.12
(2)).
A full rotation of the collar denotes 3mm of feed and rotation per one division is
0.02mm of feed. If the scale collar is locked at an operational position with the clamping
screw (Fig.12 (3)), the vertical feed amount can be read easily.
When using the main vertical spindle rapid adjustment, turn the knob to the right and
the clutch will be engaged. Now the lever is ready for use. It is convenient to use the lever
when it is necessary to affect spindle vertical feed quickly or when operation similar to that
of a drilling machine is required.
The main vertical spindle rapid adjustment lever and hand wheel for the vertical spindle
feed may not be used simultaneously.
