High-speed machining is a critical technology in modern manufacturing, offering significant improvements in production efficiency. One of the key advantages of high-speed cutting is the ability to achieve faster material removal rates while maintaining precision and surface quality. To support such operations, machine tools must meet specific requirements, including high spindle speeds, advanced control systems, and robust structural design.
The SuperMach large-scale high-speed machining center from Cincinnati, USA, features a spindle speed of 60,000 revolutions per minute (r/min), while the high-speed CNC boring and milling machine from Mikron, Switzerland, operates at 42,000 r/min. These machines exemplify the cutting-edge capabilities of today's high-speed machining equipment.
High-speed spindle systems are essential for achieving optimal performance in these machines. Leading manufacturers of electric spindles include companies from various countries:
- **Switzerland**: Fisher, IBAG, Step-up
- **Germany**: GMN, FAG
- **United States**: Precise Corporation
- **Italy**: Gamfior, Foemat
- **Japan**: NSK Corporation, Koyo Corporation
- **Sweden**: SKF Corporation
These companies are known for producing high-quality, reliable electric spindles that can operate at extremely high speeds with minimal vibration and maximum accuracy.
There are several types of bearings used in high-speed spindles, each with its own advantages:
1. **Rolling bearing** (up to 80 m/s)
2. **Hydrostatic bearing**
3. **Magnetic bearing** (up to 200 m/s)
4. **Angular contact ceramic ball bearings**
Each type of bearing is selected based on the application’s speed, load, and precision requirements.
Electric spindles often use rolling bearings for their durability and cost-effectiveness. However, for ultra-high-speed applications, magnetic or hydrostatic bearings may be preferred due to their lower friction and higher precision.
