Alternative polishing techniques have emerged as a significant advancement in surface finishing, offering considerable time savings and improved outcomes compared to traditional methods. Among these, “film polishing” stands out for its ability to achieve an excellent finished surface rapidly. This method also greatly reduces the likelihood of polishing unevenness and scratches, marking a notable improvement over conventional techniques.

For instance, a roll manufacturer in the steel industry faced challenges with removing feed marks left by whetstone polishing on large rolls. Before adopting new technology, the machining time stood at an extensive 9 hours per piece. However, the introduction of the “Super Finisher” technology marked a turning point. Remarkably, after its implementation, the process required just 30 minutes per pass, with a total of 4 passes, culminating in a dramatically reduced machining time of 2 hours per piece.

This transition signifies a monumental reduction in processing time to less than a quarter of the original duration. Consequently, the adoption of film polishing and similar advanced techniques represents a pivotal shift in the industry, enabling manufacturers to achieve superior surface finishes more efficiently and effectively.
