Revolutionizing Machining: The Untapped Potential of Tool Presetters in Indian Manufacturing

The Evolution of Machining Culture

To comprehend the significance of tool presetting, a journey back 30-40 years into Indian machining culture is essential. The initial foray into machining around the 1960s involved conventional milling machines. However, the 1990s witnessed the emergence of CNC machines, albeit with a hefty price tag. As a cost-effective alternative, retrofitting conventional machines to semi-CNC gained traction. Although this transition boosted productivity, the practice of verifying tools and components directly on the machine persisted.

Transition to CNC Machines

With the surge in exposure to high-speed CNC machines, entrepreneurs shifted their investments from retrofitted to dedicated CNC machines. However, the operating practices of machine operators remained rooted in traditional approaches, even as CNC machines offered automatic tool-offset functions.

Challenges and Mistrust

Entrepreneurs identified two primary reasons for the resistance to adopting tool presetters. Firstly, machine operators harbored a fear of measuring tools outside the machine. Secondly, companies investing in conventional and low-cost tool presetters experienced internal inaccuracies in the presetters, leading to component rejections blamed on over-hang tools, spindle runout, temperature variations, and vibrations on the shop floor. This created a pervasive mistrust in tool presetters.

Understanding the Need for Tool Presetter

Contrary to a prevailing myth that tool presetters are only for boring bars, the tool’s precise measurement is crucial, regardless of its type. Ensuring accurate measurements and relaying the data to the machine allows for more efficient control over machine operations, leading to consistent part production.

Why Tool Presetters Are Not Popular in India

Tool presetters have struggled to gain popularity in India due to prevalent myths, operator apprehensions, and past experiences with inaccurate presetters. The need for a tool presetter arises from the demand for machining intervention-free processes to enhance machine utilization and cost-effectiveness.

Choosing the Right Tool Presetter

Reflecting on the past 10-15 years, the initial high prices of tool presetters led to investments in cheaper alternatives, resulting in unsatisfactory experiences. The challenging manufacturing conditions in India, with non-temperature-controlled shop floors, necessitate selecting a tool presetter suitable for these conditions.

Justifying the Cost of Tool Presetter

As the landscape of machining has evolved, with higher machine costs compared to operator costs, the focus should shift from monitoring operator performance to maximizing machine efficiency. The cost of a tool presetter is justified by its potential to significantly enhance machine utilization, reduce operator costs, increase efficiency, and save valuable space on the shop floor.


In the contemporary manufacturing scenario, operational costs, rather than operator costs, should be the primary concern. The inefficiencies that hinder competitive pricing can be addressed through the strategic adoption of tool presetters, ultimately contributing to a more competitive industry.
