Grind Master Machines Private Limited

What Grind Master Machines Private Limited does

Grind Master Machines Private Limited, incorporated in 1984 in Aurangabad, Maharashtra, designs and manufactures specialized precision surface-finishing machines used to produce engineered finishes on metal components, with core product families organized under the NANOFINISH (microfinishing and superfinishing using film-backed abrasives and finishing stones, including SMP series superfinishers, GBQ/NF microfinishers, BRV bearing-raceway and NB ballscrew machines), METALFINISH (centerless belt grinding and finishing for tubes, bars, rods, rolls), and DEBURR (conveyorized, shaft, and pin deburring) sub-brands. The technology stack combines proprietary contact tooling (NANOTOUCH), a proprietary IoT-enabled controller (NANOSMART) supporting major PLC/CNC platforms, and embedded machine-learning process optimization (NANOPRAGNA), with 30 patents and 100+ documented innovations including the globally patented NANOSCREW ballscrew process and homegrown bearing-raceway superfinishing technology co-developed with IIT Madras.

The company operates a direct enterprise sales model selling custom-built, quote-priced turnkey machines to automotive OEMs and Tier-1 component manufacturers (e.g., Tata Motors, Ashok Leyland, Maruti Suzuki, GM, Ford, Toyota, Honda, SGM, BYD, Bosch, Bharat Forge, Cummins), bearing manufacturers, and heavy/general engineering customers, with revenue coming from hardware sales, recurring consumable abrasives and NANOTOUCH tooling, and lifecycle service contracts including AMC, retooling, and remanufacturing. Distribution is hybrid: wholly-owned operations in India (HQ plus Waluj MIDC manufacturing) and Beijing (a WOFE serving a 25% NANOFINISH market share and 200+ installed machines), supplemented by channel partners across Europe (England, Germany), East Asia (Japan, Korea), Southeast Asia (Thailand, Singapore, Indonesia), and North America (USA, Mexico). The company is privately held and founder/family-owned (Kelkar family) with no external PE or VC disclosed, professionalized management since 2015, ISO 9001/14001/45001/27001 certified operations, and a stated Net Zero 2030 sustainability commitment.

Recently, management has explicitly refocused the portfolio by divesting the ROBOFINISH robotic-grinding line to DiFACTO and licensing gear-deburring technology to Mii robotics in 2024, while accelerating new-product expansion in bearing raceway superfinishing (IMTMA Best Design Award 2025) and establishing a remanufacturing business with a 20% revenue target by 2030.
