MUMBAI, India, Feb. 13 -- Intellectual Property India has published a patent application (202641008163 A) filed by Achariya College Of Engineering Technology, Pondicherry, India, on Jan. 28, for 'automatic multi-stage surface-finishing machine with integrated polishing, puttying, levelling, water-misting, and spray-painting modules.'
Inventor(s) include Dr. S. Bhanuchandar; Dr. S. Gurulingam; Dr. S. Sridevi; Dr. G. Anand; V. Sasidharan; R. Gokulakrishnan; S. Rajalakshmi; S. Symala Gowri; Dr. A. Geetha; and Dr. K. Sethuraman.
The application for the patent was published on Feb. 13, under issue no. 07/2026.
According to the abstract released by the Intellectual Property India: "The invention relates to an automated multi-stage surface-finishing apparatus (100) integrating polishing, putty application, levelling, misting, and spray-coating within a unified motion-controlled platform. The system comprises a structural base (1) supported by wheels (2) and stands (3), vertical columns (5) with lead screws (6), and a horizontally translatable carriage (9) driven by servo motors (10). A LiDAR scanner (16) generates real-time surface maps used to adaptively control process parameters across multiple modules, including a polishing mechanism (11), a putty-spreading assembly (12), a screw-extrusion unit (13), a levelling module, a misting module, and a spray-painting module (14). Coordinated multi-axis motion ensures uniform abrasion, filler deposition, smoothing, and coating without manual repositioning of the workpiece. The apparatus enables precise, repeatable finishing of metal, composite, wooden, and moulded surfaces, supporting continuous operation across industrial production environments requiring high-quality, automated surface preparation and coating workflows."
