Multiple trends in machine-tool spindle design are currently being used to meet the needs of different industries. The trends in spindle design have been essential in ensuring that different industries can keep up with the ever-changing demands. Unfortunately, some individuals don’t understand the best trends that have helped the industry move forward. To help clear things up, here are the spindle design trends in the market.
1. New Lubrication System
Traditionally, spindles were lubricated using oil-based lubricants. However, this system was ineffective in preventing the formation of chips and other debris. As a result, a new lubrication system was developed that uses air-cooled mist. This system is much more effective in preventing the formation of chips and debris. It is also more efficient in terms of energy consumption.
2. Improved Spindle Taper
The spindle taper is the portion of the spindle that connects to the tool holder. The taper secures the tool holder and provides support during cutting operations. In the past, spindles were designed with a 60-degree taper. However, this taper is no longer sufficient for the demands of modern machining operations. Spindles are now being designed with a 70-degree taper. This improved taper provides better support and stability during cutting operations.
3. Higher Speed Ratings
The speed rating of a spindle is the maximum speed at which the spindle can operate. In the past, spindles were designed with speed ratings of 10,000 RPM. However, this is no longer sufficient for the demands of modern machining operations. Spindles are now being designed with speed ratings of 20,000 RPM. This higher speed rating allows for faster and more efficient machining operations.
4. Improved Thermal Stability
The issue of stability is a critical one for machine-tool spindles. It’s essential to communicate that spindles were not designed with thermal stability. They would expand and contract during operation, which caused them to vibrate. This vibration would lead to reduced accuracy and increased wear. Spindles are now being designed with improved thermal stability. This seems to be a welcome change as it reduces vibration and increases accuracy.
5. New Support Bearings
In any system that involves rotating parts, there will be moments when those parts are not perfectly balanced. This can cause problems such as vibration and premature wear. It’s worth indicating that spindles were designed with two support bearings. However, this is no longer sufficient for the demands of modern machining operations. As reports show, spindles are now designed with four support bearings. This provides better stability and prevents premature wear.
6. Maintenance and Refurbishment
The issue of maintenance is a critical one for machine-tool spindles. Spindles are designed to be durable and long-lasting. However, they will eventually need to be refurbished or replaced. When this time comes, choosing a company specializing in spindle maintenance and refurbishment is important. This will ensure that your spindle is properly taken care of and will last for years.
Conclusion
As you can see, multiple trends in machine-tool spindle design exist. These trends have been essential in ensuring that different industries can keep up with the ever-changing demands. Knowing these trends is important to make the best decision for your needs. Contact Fischer Precision Spindles, Inc. for more information about these trends and how they can benefit you.
