CNC Spiral Bending Machine Supplier in India
Dhanshree Engineering supplies CNC spiral bending machines across India for accurate, repeatable production of spirals, rings, and coils in rebar, pipe, tube, and structural profiles. With programmable radius, pitch, and length, our CNC controls reduce trial-and-error, improve consistency, and accelerate throughput for fabrication workshops, infrastructure contractors, and process equipment OEMs.
Working Principle and CNC Workflow
The machine progressively curves the workpiece between powered drive rollers and an adjustable forming roller. Operators program radius, pitch, segments, and quantities on the CNC interface, then the servo-driven axes and hydraulic pressure synchronize to achieve the target geometry. Closed-loop feedback and digital readouts maintain dimensional accuracy, while job recipes make repeat runs fast and reliable.
Variants of CNC Spiral Bending Machines
- CNC rebar spiral benders for columns, cages, and pile foundations.
- CNC pipe/tube spiral formers for coils, heat-exchanger helices, and railings.
- CNC section benders for flats, angles, channels, and T-sections.
- CNC ring rollers for precision rings, flanges, and circular frames.
- Custom-width machines with extended supports for long workpieces.
