Spindle box and spindle
.The spindle box of spindle direct connection type adopts thermal symmetry to reduce the influence of thermal deformation ofspindleonthe dimensional accuracy of parts.
.The front end of the spindle is equipped with large size bearings with diameter of 45, which greatly improves the rigidity and stability of the spindle.
.The design of the main shaft structure of the heat insulation source reduces the thermal displacement. Improve the accuracy and life of the spindle.
Structural Design with High Rigidity and High Precision
Introduction to machine tools
.The rigidity of the body of the integrated box-type bed is the basis to ensure that the machine tool is not deformed. The low center of gravity (the design center of gravity of the whole machine tool is 600 mm high) makes the machine tool’s amplitude small and not easy to be resonated. The long-span fulcrum (the four-point support distance is 1200 mm X840 mm) guarantees that the center of gravity of the machine tool is offset by the influence of the workpiece without the large-distance offset of the center of gravity of the In order to prevent the vibration superposition of different self-excitation frequencies and excitation frequencies, the unequal-distance net-shaped staggered bars are designed to avoid the same amplitude.
.X/Y/Z feed shaft (60m/min) optimization is a method to improve the dynamic performance with HRV control technology. The method of improving the dynamic characteristics of feed shaft by increasing transmission ratio is suitable for high-speed mobile machine tools. The output speed of servo motor does not reach the rated speed. The matching performance can be improved by increasing transmission ratio.
.Imported precision ball screw, precision linear guide rail and P4 angular contact bearing are used in all three axes.
Pursuing High Acceleration
Z-axis acceleration: 1 .1 G
|Because the Z-axi$ moves most frequently, the acceleration of the Z-axis is about two times higher than that of the old model.
|The most appropriate acceleration according to the load|
(Load 150 kg):
.The most suitable XY acceleration setting function can be set according to the load of the table.
.The acceleration load of S500 needs to be set according to the parameters
