Bangalore: The Rail Wheel Factory (RWF) at Yelahanka in Bangalore is ready to commission a new forging line to manufacture axles at its premises. Trials are currently underway ahead of its launch at the factory which supplies wheelsets and wheelsets for Indian Railways.

A senior RWF official said The new Indian Express, “The objective is to massively increase the production of axles. Currently, we are preparing 70,000 axles in our factory. Our capacity will more than double to 1.6 lakh axles when the new unit is in place. However, the forging unit will only produce rough axles. We will commission our machining unit in July 2023. The full impact on our operations will not be felt until then.

A forging line and two machining lines already exist at RWF. It manufactures axles (two wheels held together by an axle) for Indian Railways and has also won the contract to supply axles for Vande Bharat trains. “We currently have hundreds of wheels ready, but there are not enough axles to assemble them into wheel sets. When our production of axles increases, we can be ready much faster,” he adds.

These axles are intended for wagon manufacturers based largely in the east of the country. It also includes container wagons. “As part of the infrastructure push, the Railway Board plans to acquire 1,00,000 railcars over a three-year period to increase freight capacity in the country. This has resulted in unprecedented demand for RWF wheel sets,” a source said.

Elaborating on the technical aspects of the manufacturing process, another official said: “The axles are made from steel and forged on a long fully automated computer controlled forging machine at approximately 1200 degrees centigrade. To achieve the required properties, they are heat treated. Axles intended for loco operations are hardened to achieve the required properties. After cooling, it is sent to machining.

Machining is carried out on a battery of special computer-controlled machining centers. “The wheel shop’s finished axles and wheels are assembled on an automated wheel assembly press,” he explained.
