The Nagpur division of Central Railway has commissioned a Rs 6.80 crore surface wheel lathe machine at routine overhaul (ROH) depot in Ajni with a capacity of turning 20 wheels per shift. Senior divisional mechanical engineer (Sr DME) Akhilesh Choubey said, “The machine has been procured from Central Organization for Modernization of Workshops (COFMOW), a public sector undertaking in the country created in 1979 to modernize the workshops of Indian Railways.”
Choubey said the trials of turning table had begun. The computer numerical control (CNC)-operated systems provide the precise design instructions where the material or part is clamped and rotated by the main spindle, while the cutting tool that works on the material, is mounted and moved in the various axes.
“The CNC machine has a capacity to turn 20 wheels per shift. The fully automatic machine operation requires only 2-3 manpower. It will save railways Rs 32.40 lakh as wheelsets were transported to Kurduwadi and Bhusawal workshops for turning by road,” said Choubey.
The commissioning of this CNC wheel lathe will not only save the cost of transportation but will also reduce the detention of wagons and will increase wagon turnaround, and thus revenue. This will also increase the availability of wheels for increasing the target of ROH of wagons. The maintenance of the machine is covered by the original equipment manufacturer for 7 years.
