2) Analysis and Simulation
① Analysis and simulation using the dynamic state of rotating shafts
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 shafts, bearings, natural frequency, and specific frequency
It is possible to check the results of the analysis of the condition of the rotating shafts and the bearings designed by the exclusive analysis software. It can be applied to the design by calculating the natural frequency of the rotating shafts and designing them to avoid specific frequencies.
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
CNC Grinding Machine
Ensuring machining quality of high-performance spindle precision parts through the best processing equipment and optimized internal environment
4) Precision measurement
The high precision roundness meter is used to measure the shape precision of the finished spindle parts such as roundness and concentricity to achieve the best products.
5) Performance Analysis
① NRRO experiment
Nanometer-class capacitive non-contact sensors use dynamic runout and NRRO measurements TIR: Total Indicator
Run out NRRO: Non-Repeatable Run Out NRRO has a direct impact on machining accuracy.
② Thermodynamic experiment
Measuring displacement that expands due to heat generation when the spindle is driven using a nanometer-class capacitive non-contact sensor. A thermocouple is used to measure the main heat generating part of the spindle, the coolant temperature, and the ambient temperature, while simultaneously analyzing along with the expansion state of the spindle.
③ Vibration analysis
Real-time waveform, FFT spectrum verification
Vibration analysis by checking the water fall spectrum through the sweep of the spindle speed.
FRF: Frequency Response Function.
When checking the natural frequencies of spindles and structures, resonance areas can be predicted and avoided, and dangerous speeds can be detected.
⑤ Reliability tests
When a spindle reliability test for a long period of time (more than 3 months), durability verification (no load) and vibration RMS,FFT spectrum, etc. are checked in real time to improve the reliability of the product.
Tests for the anti-rust and waterproof functions of the spindle are carried out by putting the spindle in a water tank and running it normally.
