(1) Please start operation from a state that the liquid temperature

and the

room

temperature are the same as much as possible, and measure

average liquid temperature in the tank. The time indicates the time

elapsed from the start of operation.

(2) Please operate the machine in a maximum heat-generating state.

(3) Please continue the m

easurement until the difference between the

liquid temperature and the room temperature becomes constant.

(4) If because of too large heat generation

(or extremely poor heat

dissipation), you cannot continue the measurement until the difference

between the

liquid temperature and the room temperature becomes

constant, then

please continue the measurement up to as high

temperature as possible.

(5)

If cooling is conducted using a water tube provided inside the tank to

cope with large heat generation, then please measure the temperature

without running water (which uses a water cooler, etc.) as much as

possible. Then, after releasing water to make the liquid temperature

constant, please measure the liquid temperature, water flow rate,

and

temperature at the water inlet and outlet at that moment.

 Estimated calculation of the amount of heat generated by main spindle

If you need estimated calculation of the amount of heat generated by main spindle, then please contact us with the following information:

♦ Type of machine tool

♦ Capacity of main spindle motor (continuous output / 30-minute rated output)

♦ Maximum number of rotation of main spindle

♦ Type and model (manufacturer) of bearing, quantity used, precompression, and load of bearing

♦ Bearing lubrication (grease lubrication, etc.) method and cooling (jacket cooling, etc.) method

♦ Type of lubricant (or cooling) oil
