The customer for this process is Automotive Axles Limited. The input material used is a turned blank, which undergoes sequential machining operations including hobbing, spline rolling, and keyway milling to achieve the required spline and keyway profiles with high precision. These operations are performed using Pfauter Big Hobbing, MTS Spline Roller, and Jyothi Milling machines, ensuring consistency and accuracy throughout the manufacturing process. The critical parameter in this process is the spline diameter, which must be maintained within a tight tolerance of +0.03 mm to meet the required dimensional accuracy and ensure proper functional performance. Additionally, in line with customer-specific requirements, thread protection is ensured by using a thread sleeve, preventing any potential damage to the threads during handling and subsequent operations.
