There are challenges of developing and manufacturing spindle motors.The improvement in the production of Machine- tool-industry requires uninterrupted developed spindle solutions. This can be done through higher speeds, improved power density and multipurpose operations.
A machine tool may have several spindles, such as the headstock and tailstock spindles on a bench lathe. The main spindle is usually the biggest one. References to “the spindle” without further qualification imply the main spindle. Some machine tools that specialize in high-volume mass production have a group of 4, 6, or even more main spindles. These are called multispindle machines. For example, gang drills and many screw machines are multispindle machines. Although a bench lathe has more than one spindle (counting the tailstock), it is not called a multispindle machine; it has one main spindle.
Increasing globalization with standardization of components and systems, greater international collaboration and marketing activities have marked the general trend in machine industry. The productivity in the sector has improved through higher speeds, greater flexibility, improved power densities and and machine tools capable of multipurpose operation.
New modern machine tools are capable of performing an array of programmed tasks. Spindles play a key role in all machine tools. They are used to execute a range of cutting operations. They also find application in automotive and aerospace industries.
Effective and Innovative Design trends
The innovative design trend point towards the three predominant types of spindle configuration suitable for different needs of different application. The spindle configurations are :
- Belt-driven spindle units are best suited for machines with high torque.
- For general application that demand flexibility and automatic spindle change, spindle units coupled with motors are the norm. They fairly respond to high productivity,where there is limited space for the spindle, high flexibility in case of service and improved dynamic behavior.
- Engineering solutions for precision measuring and spindle monitoring
- Maintenance and refurbishment of all brands of spindle systems
