Description

Technical Field

[0002] Five-axis machining is an advanced CNC machine tool processing technology that can achieve precise processing of complex-shaped workpieces by controlling the movement of five coordinate axes simultaneously or separately on the basis of three-dimensional space. This processing method can cover multiple sides and angles of the workpiece without re-clamping the workpiece, thereby improving processing efficiency and accuracy. Five-axis machining is widely used in aerospace, automobile manufacturing, molds, medical and energy fields because it can process complex workpieces with free-form surfaces and meet the production needs of high precision and high efficiency. However, the manufacturing cost of five-axis machining equipment is relatively high, and the operating technology is relatively complex, which to a certain extent limits its popularity.

[0003] A significant advantage of a five-axis machining center is that it can complete the machining of multiple surfaces in one clamping. However, current five-axis machining centers need to make slight adjustments to the position of the workpiece after it is placed. For workpieces with higher machining precision, if the axis coordinates of the clamping body cannot be guaranteed to be accurate, the shape of the machined workpiece may deviate. Current stable fine-tuning devices usually find it difficult to perform fine-tuning operations on spherical objects. Therefore, a multi-faceted stable fine-tuning device for spherical drilling five-axis machining is proposed to solve the above problem. Utility Model Content
