otherwise it will damage the machine due to poor lubrication.

☆ All lubrication points must be injected into the net lubricating oil on time.

☆ Always pay attention to the working conditions of the oil circuit to ensure that

the spindle case and each lubrication point have enough lubricant oil.

☆ Check and adjust the tightness of the V-belt periodically.

☆ When the spindle rotates at high speed, the shift lever must not be turned under

any circumstances.

☆ Every shift must be refueling in the lubricating oil box of the guide rail to ensure

21
sufficient lubrication during the movement of the saddle. Shell lubrication method see

"lubrication of machine tools".

! It is prohibited to use the method of manipulating the spindle in the opposite

direction to brake the machine. If you need to reverse the spindle, stop the spindle

and start the spindle reverse operation.

6.2 Lubrication and Cooling System for Machine Tool

The cooling pump delivers the coolant through the conveying pipe to the cutting tool,

and the nozzle is mounted on the slide rest of the tool carrier, which can follow the

cutter.The maximum flow rate of the cooling pump is 12 litres per minute. When the

coolant is collected from the oil tray, the foot is remitted to the right bed foot. Before

the inflow, the iron chips are filtered out by the filter plate. The tiny iron chips are

deposited at the bottom of the box and cleaned every three months to half a year. The

nozzle has a regulating valve, which can adjust the size of the flow.

The cooling liquid can be generally a mixture of alkaline water and soapy water. It

can also use water-dipping oil (a milky mixture) and dilute diesel oil.

The service life of the machine tool is closely related to the timely and correct

lubrication of the various parts and components. Lubrication oil should be used

Clean, non-acidic, should not contain water and hard particles. It is advisable to use

refined mineral oil. The commonly used oil number is 20# industrial oil

(Engel viscosity 2.6-3.30 at 50°C).

6.5 Cleaning Methods and Precautions for the Cooling System

☆ After the machine tool is used for half a year, the cooling system of the machine

tool should be cleaned to ensure the normal use of the machine tool cooling system.

The cleaning method is as follows:

☆ Cut off the power supply of the machine, close the cooling pump switch, and

disconnect the power plug of the cooling pump from the power cable.

☆ Pull the cooling box out of the rear of the machine and discharge the residual

24
cutting fluid from the drain hole of the cooling box.

☆ Loosen the screw fixing the cooling pump to the cooling box and remove the

cooling pump.

☆ Rinse the cooling pump port with clean water.

☆ Clean the sediment in the cooling tank, clean it with clean water, and wipe the

cooling tank to clean.

☆ Fix the cooling pump to the cooling box.

☆ Push the cooling box to the designated position in the machine.

☆Connect the power supply plug of the cooling pump to the power cord.

Note:

☆ When removing the cooling pump's power plug, do not use excessive force

to avoid damaging the power plug.

☆ When cleaning the cooling pump, do not pour water onto the power plug to

avoid electrical short circuits.
