Installation method of the lightest machine bed

Installation method of machine tool

1 Lifting and transportation

5. Displacement measurement: the lifting and positioning of the machine tool with a resolution of 0.01mm should use the special lifting tools provided by the manufacturer, and other methods are not allowed. Special lifting tools are not required, and wire ropes should be used to lift and place according to the positions specified in the instructions

2. Foundation and position

the machine tool should be installed on a solid foundation, and the position should be far away from the vibration source; Avoid sunlight and thermal radiation; Place it in a dry place to avoid the influence of humidity and airflow. If there is a vibration source near the machine tool, high-precision and powerful data must be set around the foundation. 1 Let's have a look at the processing capacity; Anti vibration ditch

3. Installation of machine tool

the machine tool should be leveled in a free state when placed on the foundation, and then the anchor bolts should be locked evenly. For ordinary machine tools, the reading of the level meter does not exceed 0.04/1000mm. For high-precision machine tools, water greatly reduces the interference caused by the peak current caused by the transient conduction and cut-off of the current load, and the level meter does not exceed 0.02/1000mm. When measuring the installation accuracy, it should be carried out at a constant temperature, and the measuring tool should be used after a period of constant temperature. When installing the machine tool, try to avoid the installation method that causes forced deformation of the machine tool. When installing the machine tool, some parts of the machine tool should not be removed casually. The removal of parts may lead to important new distribution of internal stress in the machine tool, thus affecting the accuracy of the machine tool

4. Preparation before commissioning

after the geometric accuracy of the machine tool passes the inspection, the whole machine needs to be cleaned. Cotton cloth or silk cloth soaked with detergent shall be used, and cotton yarn or gauze shall not be used. Clean the antirust oil or antirust paint applied to protect the guide rail surface and machining surface when the machine tool leaves the factory. Clean the dust on the outer surface of the machine tool. Apply the specified lubricating oil of machine tool on each sliding surface and working surface

carefully check whether all parts of the machine tool have been filled with oil as required and whether there is enough coolant in the cooling box. Whether the oil of the hydraulic station and automatic room lubrication device of the machine tool reaches the specified position of the oil level indicator

check whether the switches and components in the electrical control box are normal and whether the plug-in integrated circuit boards are in place

power on and start the centralized lubrication device to fill all lubricating parts and lubricating oil circuits with lubricating oil. Make all preparations before the action of all parts of the machine tool
