Coolant: 冷 却液

The coolant m anagement (or the air supply on the workpiece) is carried out whether in m anual mode or in aut o m atic. Doubtfully the first 

one prevails on the second one.

可手动和自动控制冷 却液（或气用于工件）。毫无疑问，手动优先。

For this purpose, it has been provided on the m ain control panel a two positions selector key: m anual or aut o m atic mode. 

为此，主面板上设置了一个2位置选择键：手动或自动模式。

When the selector is in the aut o m atic mode the key for the external and internal coolant is inhibit and its control is assigned to the NC.

如果该选择键处于自动模式位置，则控制内外冷 却液的按钮停止而由NC控制。

In fact, by the functions M7, M8, M97, M98 it is possible to control the internal and external coolant, the air supply inside and outside the 

workpiece respectively, while the function M9 disables all these functions.

事实上，M7,M8, M97, M98功能可以分别控制内外冷 却液，工件内外气体供给，但M9关闭了这些功能。

The la mp relevant to the internal, external coolant or the air supply (led on the push button INTERNAL AIR – EXTERNAL AIR on the operator 

control panel) will be ON when the function is active, and OFF on the contrary.
