How To Ensure The Accuracy Of Gantry Milling Machine in Operation
To ensure the accuracy of the gantry milling machine in operation, the foundation of the gantry milling machine must have sufficient strength, rigidity and stability. The power of the gantry milling machine mainly depends on the motor, but there is another important point that can not be ignored, that is, the lead screw. If the quality requirements of the lead screw cannot be met or the lead screw is too thin, when the motor power is too high, the machine tool speed is fast, or the cutting capacity is large, the lead screw may be deformed or even broken. Therefore, in this case, the bearing capacity of the lead screw should be considered.
The design should be carried out in strict accordance with the machine tool load diagram provided by the machine tool manufacturer. It is necessary to ensure the contact accuracy and rigidity of the gantry milling machine base, supporting block and cement foundation, which is the key to ensure the installation quality and machine tool accuracy of the gantry milling machine, It is of great importance to the machining accuracy and processing capacity of the gantry milling machine. The gantry milling machine has high machining accuracy and productivity. It is suitable for processing the plane and slope of large workpieces in batch and mass production. In addition, doing a good job in the calibration of the gantry milling machine is also good for the accuracy of the gantry milling machine. We can calibrate the gantry milling machine through the following steps.
Correct the perpendicularity between the fixed clamp and the spindle axis of the gantry milling machine with a probe. When machining long workpieces, a pair of fixed clamp shall be installed at the vertical position of the spindle axis of the milling machine. At this time, the probe can be used for correction. After, use a dial indicator to correct the perpendicularity or parallelism between the fixed clamp opening and the spindle axis line of the gantry milling machine.
