IIIInstallation requirements for use

1Operator requirements: This machine tool is a high-precision CNC grinder, and the operator is required to have basic skills in operating CNC grinders. They must receive training from Party B and master safety operating procedures before they can use it.

2Installation and environmental requirements:

The fluctuation of power supply voltage±10%Internally, the working temperature is generally required to be installed in a constant temperature room（20℃±1℃）Internal useThe humidity is less than75%, installation should be away from the seismic source. If conditions permit, isolation trenches can be made. The horizontal placement of the equipment should be less than 0.02mm, and adjustable shims can be used to adjust the level.

3The compressed air source requires three-stage filtration. This machine tool is equipped with a precision three-stage filter, but the supply air source needs to be processed by a dryer, requiring a pressure of0.5-0.7MPa range, moisture content less than 90%, oil content less than 90%, temperature 17-19 ℃, impurity content less than 1um.

4. The spindle cooling water requires constant temperature, with a temperature range of 17-19 ℃, a flow rate of 2L/min, and a pressure of 2-3kg.
