Excerpts:
Shubhline Automation Pvt Ltd was founded with a vision to address the growing need for high-quality machine tool solutions in India. Initially, the company specialized in reconditioning and retrofitting machine tools. This phase involved refurbishing old and worn-out machines, upgrading their components, and enhancing their performance to meet modern industrial standards.
During this period, Shubhline Automation honed its expertise in machine tool engineering. The team gained invaluable experience in understanding the intricacies of various machine tools, their operational challenges, and the specific requirements of different industries. This foundational knowledge set the stage for future innovations.
The primary motivation behind Shubhline’s transition into manufacturing CNC machines was the growing demand for high-precision and efficient machining solutions. The industrial sector in India was rapidly evolving, with increasing emphasis on automation, precision, and productivity. This shift necessitated advanced machining solutions that could meet the stringent requirements of modern manufacturing processes.
Despite India’s vast population and industrial potential, a significant portion of high-quality machine tools were being imported from smaller countries like Taiwan, Italy, and Germany. This reliance on imports highlighted a gap in the domestic production of top-notch machine tools. Recognizing this disparity, we were motivated to contribute to the local manufacturing landscape by producing world-class CNC machines within India.
Shubhline plays a significant role in contributing to the Atmanirbhar Bharat initiative by manufacturing advanced CNC machines domestically. By producing high-quality machine tools within India, the company reduces dependence on imports and strengthens the local manufacturing sector. This aligns with the broader vision of making India self-reliant in critical industrial sectors.
Developing India’s first double column CNC machining center with a W-axis represents a significant technological advancement in the country’s manufacturing capabilities. This innovation places Shubhline at the forefront of CNC machine tool technology in India, showcasing the company’s ability to develop complex and highly sophisticated machinery.
The inclusion of a W-axis in the double column CNC machining center enhances the machine’s capabilities. The W-axis allows for vertical adjustment of the cross rail, providing additional flexibility and precision in machining operations. This feature is particularly beneficial for machining large and complex workpieces, as it enables the machine to handle varying heights and maintain accuracy across different machining tasks.

The use of a honeycomb structure in the casting of Shubhline Automation’s CNC machines significantly enhances their robustness. This innovative design provides superior strength-to-weight ratio, offering high rigidity while maintaining lightweight characteristics.
The honeycomb structure effectively dampens vibrations during machining operations, improving precision and surface finish quality. This leads to higher accuracy and consistent performance, especially during heavy-duty operations.
The use of FG350 grade cast iron in the casting process further enhances the robustness of the machines. FG350 is known for its excellent tensile strength, wear resistance, and durability, making it ideal for high-stress machining environments.
FG350 cast iron provides excellent thermal stability, reducing thermal deformation and maintaining accuracy even under prolonged use and varying temperature conditions.
We employ a two-time stress-relieving process in the manufacturing of our CNC machines. This process effectively reduces residual stresses in the material, which can cause distortions and affect machining accuracy over time. By performing stress relief twice, the dimensional stability of the cast components is significantly enhanced, ensuring that the machines retain their precise alignment and geometry throughout their operational life. Finite Element Analysis (FEA) is used to simulate and analyze the design of CNC machines under various load conditions. This advanced analysis helps identify potential stress points and optimize the design for maximum strength and durability.
FEA provides predictive insights into how the machine will perform under real-world conditions, allowing for design modifications and improvements before the actual manufacturing process. This results in a more robust and reliable final product.
