Description

Technical field

[0001] The invention belongs to the technical field of spindle high-speed dynamic balance, and relates to an online dynamic balance measurement and control system for high-precision machining spindles. Background technique

[0002] The development direction of modern machining is high-speed, high-precision, and high-efficiency. The high-speed of machine tools has become the current development trend of machine tools. This trend puts forward higher requirements for machine tools, and the spindle is the core component of machine tools to a large extent Determines the processing performance of the machine tool. In the actual processing engineering, due to the influence of factors such as manufacturing error, material unevenness and installation error, the spindle must have an imbalance. Unbalance usually leads to spindle vibration, which is particularly obvious on high-speed machine tools. Excessive spindle vibration will directly affect machining accuracy, and at t...
