2) Analysis and Simulation
① Analysis and simulation using dynamic state of rotating shaft
Dedicated analysis software allows you to analyze the mode of the dynamic state of the spindle, and predict the state of the spindle with respect to tools and collets.
② Analysis and simulation using rotating shaft, bearing, natural frequency and specific frequency
It is possible to check the results of the analysis of the condition of the rotating shaft and the bearing designed by the exclusive analysis software. It can be applied to the design by grasping the natural frequency of the rotating shaft and designing to avoid the specific frequency. .
Build a complete design using the above features and then use the best processing equipment
We use high quality products to process and minimize errors with various tests.
3) Precision processing
