Did you know that the quality of a product’s surface can significantly impact its performance, longevity, and resistance to various forms of wear and tear? In fact, studies indicate that nearly 70% of all mechanical failures are directly related to surface characteristics. This eye-opening statistic highlights the importance of surface treatment processes in the realm of CNC (Computer Numerical Control) machining, especially when it comes to making parts from steel. As industries increasingly demand components that meet high-performance standards, understanding the common surface treatment methods after CNC machining becomes paramount for manufacturers, engineers, and designers alike.
In this blog, we will delve into the various surface treatment methods employed after CNC machining of steel, their advantages, and how businesses can implement these techniques to optimize their operations.
