What is the normal service life of cast iron disc?

The service life of cast iron fixed plates does not have a fixed period, and it mainly depends on four factors: manufacturing quality, service strength, maintenance level, and environmental conditions. A high-quality (such as HT250 or above material, fully aged) and properly maintained fixed plate can serve as a reliable benchmark for a lifespan of 15-25 years or even longer in general industrial environments; Poorly maintained or overloaded fixed plates may result in serious accuracy failure within a few years.

Precision life and structural life are two different concepts. Even if the platform itself is intact, the flatness accuracy of its working surface will gradually decline due to wear, scratches, and stress release. Through regular professional scraping and repair, the accuracy can be partially restored, significantly extending its effective service life, which is the core value of high-quality cast iron fixed plates.

The most critical influencing factor is the method of use and maintenance. Strictly adhering to operating procedures (such as avoiding hard object impact, prohibiting illegal dragging of workpieces), insisting on daily cleaning and rust prevention, and conducting annual flatness testing are fundamental to maximizing the service life. In short, cast iron fixed plates are more like "process equipment", and their lifespan directly reflects the user's level of process management.
