高速主轴系统是超高速机床的核心部件。目前使用的主轴系统支承部件一般均是滚动体为钢球的滚珠轴承,滚动球轴承的润滑问题是决定高速主轴系统,乃至超高速机床是否能够正常工作的关键。轴承润滑方式主要有油脂润滑、油雾润滑、油气润滑和喷油润滑等,它们所适应的主轴转速依次递增,成本也依次增大。因此如何针对不同的 High-speed spindle system is the core components of ultra-high-speed machine tools. Currently used spindle system support components are generally ball rolling ball bearings, rolling ball bearing lubrication problem is to determine the high-speed spindle system, and even ultra-high-speed machine tool is the key to the normal work. The main bearing lubrication methods are grease lubrication, oil mist lubrication, oil and gas lubrication and fuel injection lubrication, etc. They adapt to the spindle speed increased in turn, the cost increases in turn. So how to target different
