Mounting the dead centre:
Verify that the dead centre and the tailstock bore are clean without any dirt, dust, grease or
oil. If there is dirt or excessive oil on the equipment surfaces, the Morse drill chuck taper will not
be locked tightly.
Turn the tailstock handwheel to make the fixed component extending about 20MM.
Place the dead centre Into the tailstock bore and the dead centre will be fixed in its suitable
central position.
When taking out the dead centre, rotate the turn plate on the tailstock to make the fixed
component retracted into the tailstock and, in this way, the dead centre will be jacked out of it.
4.3 Tool Post
The tool post can be rotated to the predetermined 4 90-degree position or any angle in-between and can
fix 4 tools one by one at most.
Tool use
:
Tool is selected according to the requirement.
The tool bit exposed out of the tool post shall be
as little as possible and shall be fixed securely with
two nuts, which is helpful to
maintain its
sturdiness.
Ensure that the tool bit is just on the
center line of the workpiece. If not, use the
gasket to have it just on the center line.
Notice: Check the tool bit to find out
whether it is at the correct height and ensure that the tool bit should be kept on a same
height with the dead centre of the tailstock.
If both the tops are at the same height or the top of the tool bit is lower than the top
of the dead centre, then the height is correct.
If the tool bit is higher than the dead centre, then grind the tool to a suitable position
or replace it with a correct tool.
4.4 Longitudinal Carriage
Move the longitudinal carriage so that it is
perpendicular to the longitudinal axis and the precision
displayed on the dial plate on the hand crank is
0.025mm.
Adjust the longitudinal carriage:
Rotate the hand crank to draw back the longitudinal
carriage from the starting point for 0.5mm at least and then
move it forward to its starting point.
Note: This step will eliminate any non-controlled move
of the lead screw (or backlash), so that the readings on the
