3, Super Power Motorized Spindle
Configure the 18000rpm AFMING spindle. Fully consider parts processing, mold processing and other special processing conditions, to provide customers with tailor-made spindle solutions, expand the processing range, improve processing efficiency.
Internal cycle cooling: Motor cooling&Bearing cooling
With internal circulation cooling, effectively solve the temperature difference between the inner and outer rings of the bearing, and achieve high rigidity and precision of high-speed operation of the spindle.
Features
- Low rotor temperature rise: The whole rotor of the main shaft, including the iron core of the motor rotor, is cooled by internal circulation to achieve low temperature rise.
- The thermal elongation of the spindle is small: The temperature rise of the spindle rotor is low, and the thermal deformation of the material is small.
- The thermal stability time of the main shaft is short: The internal circulation cooling of the spindle can quickly reach the state of thermal balance
- Spindle rigidity: Bearing temperature rise is low, the same speed can be applied to larger size bearings and larger preload, improve rigidity
- Spindle limit speed is high: Bearing temperature rise is low, the same specification bearing can achieve higher speed operation
- Low bearing temperature rise: When the bearing is cooled, the bearing temperature rise is low and the lubrication life is long
18000rpm electric spindle HSK-A63: Suitable for high finish surface processing
4, Using finite element analysis and dynamic optimization, engineers greatly improve the performance of the whole machine.
During the design, engineers use FEA for dynamic optimization to achieve the best match of the structure quality, stiffness, and damping of the whole machine, reducing the cross dynamic flexibility between the tool tip and the workpiece, improving the regeneration flutter limit during rough machining, enhancing the cutting amount of rough machining, and achieving the purpose of efficient cutting. At the same time, engineers reduce the relative amplitude between the tool tip and the workpiece, improving the surface finish during processing, decreasing the vibration speed of the tool tip, and reducing tool wear.
- Dynamic optimization through FEA, effectively improve the anti- vibration of the whole machine
- Accurately calculate the optimal dynamic rigidity under actual working conditions
- Improve the natural frequency and cutoff frequency of the feed drive system, effectively reduce the positioning time and the lag of the feed system, and achieve highly responsive dynamic performance and high-speed machining profile accuracy
