Machines
Multiple technologies, one workshop: CNC laser and plasma cutting, MIG, TIG, MMA and submerged arc welding, and cobot and robotic welding — engineered, built and tested in India.
RA Machine is the CNC machine division of R.A. Auto Engineering Works, an engineering company in Kolkata, India, founded in 1989 and building machines since 2008. We make CNC laser and plasma cutting machines, MIG, TIG, MMA and submerged arc welding machines, and cobot and robotic welding systems, and supply them across India and abroad. We are GST registered, hold an Import Export Code for export, and have supplied Indian Railways since 2022 as a preferred vendor for certain safety-critical items. Every machine below is configured to the job and available for delivery and installation across India and for export, backed by our own operator training and after-sales service.
