2-5 Cutting oil
There are two general types of cutting oil, i.e., water-soluble cutting oil and
water-insoluble cutting oil, and these are further divided into many groups. As selection of
the cutting oil depends on each cutting condition, particular trade names or groups cannot be
specified here but it is necessary to observe the following:
(1) Use of water-insoluble cutting oil.
Examples:
Mineral oil Light oil, machine oil and spindle oil
Animal and vegetable oil
Lard, olive oil, colza oil, soybean oil and
castor oil
(2) The capacity of the cutting oil tank is approximately 9.25 gallons.
(3) Cutting oil should be supplied through an oil strainer into the cutting oil intake
provided on the lower part of the column.
2-6 Wiring
The power cord should be connected to the
terminals R.S.T. (Fig. 4-2). On completion of
the connection, turn on the power switch (Fig. 4-1)
provided on the side of the power box and turn the spindle
rotating direction indicating change over switch to the right.
After finishing the above preparations, start the main spindle.
(See section for spindle starting, spindle stopping and spindle
brake).If the rotation direction of the main spindle is
clockwise, connections are correct. If rotation is counter-
clockwise, exchange connections of two of the three wires
of the power core.
2-7 Lubrication
Prior to starting, each moving part must be lubricated with suitable lubricating oil. Refer
to (Table.1) for instructions to lubricate the spindle head gears, quill and slide ways.
The Lubrication oil to be used for each part is also listed in Table 2 and 3. It can be used
for selecting the correct lubricant to keep the machine in its best condition.

3-5 Change of vertical spindle speed
The vertical spindle speed should be chosen according to work piece material, cutter
diameter and cutter material tables 5 and 6 for you reference.
To change the vertical spindle speed, operate the high-low speed change lever (Fig.7-5)
and rotating speed change handle (Fig.7-7).R.P.M. can be read out from the indicator (Fig.6
(2)). The rotating direction of the speed change handle is opposite to the direction of the
indicator.
The brown area of the indicator represents low speed, the blue area represents high
speed. Put the high-low speed change lever at the position “-“, when the vertical spindle
R.P.M is at the low speed range (120-720 rpm).Put the high-low speed change lever at the
position”+”, when the vertical spindle R.P.M.is at the high speed range (600-3600 rpm).
By putting the high-low speed change lever at the position “N”, the spindle gears can be
then disengaged, and the vertical spindle can be rotated by hand. Operation of high-low
speed change lever: hold the handle, push it slightly, the lock pin will then disengage, move

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. f 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. t 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.
