The customers for this process are Automotive Axles Limited and Bharat Forge Limited. The input material used is a forging, which undergoes a sequence of precision machining operations including OD turning, chamfering, threading, bore turning, and punching to achieve the required dimensional and functional specifications. These operations are performed using advanced machines such as the Moriseki Turner and Spectra Turn Turner, ensuring high precision, surface finish, and process consistency. The critical parameters for this process are the bearing diameter, which must be maintained within a tight tolerance of ±0.025 mm, and the spline diameter, which requires a tolerance of +0.03 mm to ensure proper fit and performance. In accordance with customer-specific requirements, VMS inspection is carried out for all critical parameters, and punching is performed as part of the final verification process to ensure product traceability and compliance with quality standards.
