Slender Shaft Processing

Bar stock with a length to diameter ratio of more than 20 is known as slender shaft. Due to its large aspect ratio and poor rigidity, it is highly susceptible to deformation by cutting force and cutting heat during processing, which brings great challenges to the machining. However, WELLTECH, with its outstanding technical strength and innovative spirit, has successfully overcome the problems of unstable machining quality, high machining cost and low efficiency by deeply optimizing the geometric parameters of the tool and the technological scheme, and by adopting specially designed special jigs and fixtures. It has achieved the processing of workpieces with a maximum length of 4500mm, a diameter of Φ55, a material removal of up to 50%, and workpieces with complex cavities, with straightness up to 0.2, and both the shape and position accuracy and dimensional accuracy meet the product quality requirements.
