MUMBAI, India, Jan. 9 -- Intellectual Property India has published a patent application (202531128225 A) filed by Indian Institute Of Technology (Indian School Of Mines, Dhanbad), Dhanbad, Jharkhand, on Dec. 17, 2025, for 'a bench-top knurling machine for micro-texturing on flat surface.'
Inventor(s) include Dr. Suman Saha; Mr. Piyush Sharma; and Dr. Mohan Kumar.
The application for the patent was published on Jan. 9, under issue no. 02/2026.
According to the abstract released by the Intellectual Property India: "A bench-top knurling machine for micro-texturing on flat surface The knurling machine is built upon a rigid mild steel base plate (100) with two vertical side plates (101,111) being welded to it forming the main structural columns of the machine. A precision XYZ translation stage (103) is mounted upon the base plate (100). A knurling tool holder (106) having two knurling tools (107) each of diameter of 20mm mounted on it, is clamped in a three-jaw self centring chuck (15). This entire tool and chuck assembly are fixed to the side plates (101,111). A mechanical vice (104) is disposed firmly on the translation stage (103) to hold the workpiece (108). The dual knurling tool head is adapted to work with interchangeable wheels of different surface patterns to generate straight, cross, diamond or customized textures. The translation stage provides incremental motion along two linear axis to control feed rate, depth of engagement, and texture geometry. As the workpiece is fed against the freely rotating knurling wheels, the applied contact pressure produces predefined microtexture by plastic deforming on flat surfaces."
