Abstract:

This paper presents an enhanced CNC machine tool specifically tailored for the precision manufacturing required in biotechnological equipment production—the segment grinding machine. Designed with a programmable logic controller (PLC), this machine significantly boosts operational efficiency and achieves high precision in error-free manufacturing. Segment grinding machines are engineered to form segmented outer diameters on parts, which are crucial in the precise assembly of biotechnological devices. Common models in the market, however, face limitations such as small movement tracks and lack of stabilization when processing elongated parts, often leading to oscillations that compromise accuracy. Addressing these challenges, this study introduces an innovative grinding wheel dressing mechanism. This key device is central to CNC grinding machines and has been specifically developed to support automatic dressing, thereby enhancing both the precision and efficiency of the grinding process. The implementation of this advanced mechanism ensures substantial improvements in the quality of the finished biotechnological components, aligning with the stringent requirements of the biotech industry for both functionality and reliability.
