Air Bearing Spindles for Super High Speed Machining
The use of air bearing spindles in machining is becoming increasingly common as manufacturers strive to increase their productivity and efficiency. Air bearing spindles can offer high speed, very precise machining and are typically used in machining tasks that require very intricate and highly precise results, such as grinding, drilling, polishing and milling tasks.
An air bearing spindle, unlike a traditional ball bearing spindle, is designed to have no contact between moving parts — eliminating friction and the associated heat that can lead to deformation and distortion. Air bearing spindles, sometimes referred to as fluid dynamic bearings, are constructed using a series of pressurized air bearings surrounding a spinning shaft. As the bearings encounter pressure changes, the pressurized air causes the shaft to float, which allows it to move with much greater precision and speed than a conventional ball bearing spindle.
Air bearing spindles are well-suited for high-speed machining. They allow for very precise machining and are ideal for applications where accuracy and speed are both critical requirements. Most air-bearing spindles can reach speeds of up to 60,000 to 80,000 rpm, making them ideal for many high-speed machining jobs.
The use of air bearings offers several potential benefits over traditional ball bearing spindles. As noted above, the lack of friction and the associated heat build-up results in increased accuracy and a longer service life. Additionally, the increased speed capability can improve production and reduce cost per part. Air bearing spindles also require less maintenance than ball bearing spindles — making them a cost-effective solution for operators who are looking for extremely high speed machining capabilities.
When selecting an air bearing spindle, there are several important considerations to bear in mind. Firstly, the speed requirements must be taken into account — not all air bearing spindles are capable of reaching the same speeds, and selecting the wrong spindle can result in inadequate performance. Additionally, machine operators must consider the overall construction of the spindle — with the rigidity and precision increasing as weight and overall size decreases.
Overall, air bearing spindles can offer highly accurate, super-high speed machining capabilities in a variety of applications. Compared to traditional ball bearing spindles, air bearing spindles are very reliable and require minimal maintenance — making them an ideal choice for operators looking for a cost-effective solution for their machining requirements.
宇气轴承主轴应用于加工领域的频率越来越高，因为厂家努力提高他们的生产效率和能效。空气轴承主轴可以提供高速，精密加工，通常用于需要非常复杂和高精度的加工任务，如研磨，钻孔，抛光和铣削任务。
与传统的滚珠轴承主轴不同，空气轴承主轴设计没有转动部件之间的接触，消除摩擦和相关的热量，可以避免变形和扭曲。空气轴承，有时称为流体动力学轴承，是用一系列加压空气轴承包围旋转轴杆而构造的。当轴承遇到压力变化时，加压空气使轴浮动，使其能够以比传统的滚珠轴承主轴更高的精度和速度运动。
空气轴承非常适合高速加工。它们允许非常精确的加工，对于精度和速度都是关键要求的应用来说是理想的。大多数空气轴承的转速可达到6万到8万转/分，使它们成为许多高速加工任务的理想选择。
与传统的滚珠轴承相比，使用空气轴承可以带来几个潜在的好处。如上所述，消除摩擦和相关热量的积累可以提高精度和延长使用寿命。另外，增加的速度能力也可以提高生产效率，降低每块部件的成本。空气轴承也比滚珠轴承需要更少的维护，因此对于那些需要高速加工能力的操作者来说是一个高性价比的解决方案。
在选择空气轴承时，有几个重要的因素需要考虑。首先，需要考虑速度的要求--并不是所有的空气轴承都能达到相同的速度，选择不正确的轴承会导致性能不足。此外，机器操作者也必须考虑轴承的整体结构，硬度和精度随着重量和整体尺寸的减小而提高。
总的来说，空气轴承可以用于各种应用场合，提供高精度，超高速度的加工能力。与传统的滚珠轴承相比，空气轴承非常可靠，需要最少的维护，使其成为寻求成本效益解决方案的操作者理想的选择。
