In the world of precision machining, the grinder is the final arbiter of quality. I am a 5th-class Surface and Cylindrical Grinder with six years of experience in the tool room of a major defense manufacturing enterprise, specializing in achieving mirror finishes and micron-level tolerances on hardened components.
Between 2018 and 2024, I operated manual surface grinders (3Г71), cylindrical grinders (3У10А), and internal grinding machines (3К227В). My work focused on finishing critical parts for UAV propulsion systems and optical instrumentation. I routinely held surface finishes down to Ra 0.16 and geometric tolerances (cylindricity and runout) within 0.003 to 0.005 mm. I am highly experienced in grinding hardened tool steels (ShKh15, 9KhS), titanium, and duralumin, and I know exactly how to select and dress the appropriate abrasive wheels for each material.
One of my most demanding projects involved grinding the precision shafts and axes for the reduction gears of a UAV's propulsion system. I achieved a deviation from perfect roundness of no more than 2 microns, ensuring the gears operated silently and smoothly under high RPMs. I also optimized the intermediate grinding process for titanium parts, reducing the cycle time per component by 12%.
I hold a vocational diploma in Grinding and Machining, along with a 5th-class state certification. I possess extreme concentration, deep respect for micron-level tolerances, and a personal collection of high-precision measuring instruments, including optimeters and micrometers. I am seeking a full-time, on-site role in a precision machine shop in Detroit, MI, targeting $68,000 USD.
