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 Lard olive oil colza oil soybean oil, 

Vegetable oil castor oil 

(2) Capacity of the cutting oil tank is about 9.25 gallon. 

(3) Cutting oil should be supplied through an oil strainer into the cutting oil intake provided on the 

lower part of the column. 

Warning: 1. To avoid fire, prohibited use low flash point cutting oil for machining magnesium, 

aluminum or similar pyrophoric or explosive articles. 

2. Do not dump waste cutting fluid at any place. Dispose the waste fluid under 

regulation of local low for environmental 

protection. 

2-6 Wiring 

The power cable should be connected to the terminals R.S.T. 

(1) (Fig.4). On completion of the connection, turn on the 

power switch provided on the cabinet. 

After finishing the above preparations, start the main spindle. 

(See section for spindle starting, spindle stopping). 

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 

cable. 

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 gears and sideways.

The lubrication oil to be used for each part is also listed in tables 2, and 3, it can be used

for 

selecting the correct lubricant to keep the machine in its best condition.
