3A Yantra Inc. was established in 2016 by a team of engineers, all carrying more than 25 years of experience in machine building. We design and manufacture automatic, high-production and high-precision machines — Double Disc Grinding Machines, Double End Boring Machines, CNC Polygon Turning, Rotary Transfer Machines, CNC Centering & Facing Machines, and Special Purpose Machines tooled to each customer's component.
Beyond machine building, we execute complete Plant Automation projects — Robotic Automation, Pick & Place, Gantry systems and conveyors for material handling — and build multi-operation machines around Rotary Indexing Tables to raise overall productivity on the shop floor.
Five connected capabilities, one engineering team — from a single grinding spindle to a fully automated line.
Grinding, boring, turning, milling, facing & centering machines built to spec.
CNC, PLC, servo & hydraulic control integration on every machine we build.
Line-level automation that connects machines, handling and inspection.
Robotic pick & place cells that cut manual handling and cycle time.
Overhead gantry systems & transfer conveyors for material movement.
Engineered around your components, built for precision, and designed to scale seamlessly with your production needs.
Precision double disc grinding delivers simultaneous face grinding, consistent accuracy, smooth finishes, and production efficiency.

We take automation past the spindle — connecting handling, transfer and inspection into one coordinated line.
Robotic arms for loading, unloading & component transfer between stations.
Repeatable, high-speed placement synced to machine cycle time.
Overhead gantry automation for heavier components across long spans.
Material-handling conveyors linking machines into a single flow.
What our customers get with every machine we ship.
Solutions built for a real competitive advantage, with complete customer satisfaction as the goal.
Our own design team engineers every machine to the customer's exact process, not a catalogue spec.
Best-in-class manufacturing partners for subassemblies, so quality and timelines stay consistent.
Founded by engineers with a combined 25+ years in machine building — not a startup learning on the job.
Tell us about the component or the line you need to build — our engineers will get back to you with next steps.
Designing & manufacturing precision machines since 2016.
