The customer for this process is Automotive Axles Limited. The input material used is a turned blank, which undergoes the hobbing operation to generate accurate spline profiles as per the required specifications. The process is carried out using BBC Colman Hobbing and Cooper Hobbing machines, ensuring high precision and repeatability in spline formation. The critical parameter in this process is the spline diameter, which must be maintained within a tolerance of +0.03 mm to ensure dimensional accuracy and functional reliability. Additionally, as part of customer-specific requirements, thread protection is ensured by using a thread sleeve, preventing any potential damage to the threads during handling and subsequent processes.
