High precision machining device for large-scale key parts of aluminum alloy

Abstract

Abstract A high precision machining device for large scale curve groove of aluminum alloy key parts has been developed, the device is composed of a workpiece spindle drive system, a lathe bed, a hydraulic clamp system, a cutter spindle drive system, a deep feed shaft drive system, a linear feed shaft drive system, a data acquisition feedback system and a numerical control system, it improves the manufacturing precision and the whole strength and rigidity of the curve groove of the large aluminum alloy key parts, especially can be used for the whole precision machining of the curve groove of the high strength and high rigidity aluminum alloy key parts, and reduces the production cycle and cost, the key technical problems of cutting tool deformation and vibration control in NC milling and grinding wheel wear and correction in NC grinding are solved, it can meet the requirements of high-strength, high-rigidity and high-precision machining of large-scale aluminum alloy key parts.
