Overview of Flat Rulers:

Flat rulers, essential for precise measurements in various industries, are typically crafted from materials like fine gray cast iron or alloy cast iron. Their surfaces must be meticulously crafted to ensure they are free from defects such as sand holes, pores, cracks, and more, which could impair both appearance and performance. The optimal hardness for their working surface ranges between 170 to 220HB.

Overview of Rock Rulers:

Rock rulers, including granite and marble varieties, are crafted from "Jinan Qing" stone using advanced mechanical processing and meticulous manual grinding. Known for their sleek black luster, uniform texture, and exceptional stability, these rulers boast high strength, allowing them to withstand heavy loads and normal temperature variations. Their non-rusting, non-magnetizing, and non-deforming properties ensure reliable performance over time. In contrast, cast iron rulers feature meticulously scraped measuring surfaces that retain lubrication and prevent dust accumulation, thus enhancing stability and reliability as precision tools. These attributes make them ideal for both measuring and grinding applications.

Key Features of Flat Rulers:

In geometric measurements, flat rulers simulate datum straight lines crucial for accuracy. The most prevalent types are cast iron and rock variants. The primary indicator of a flat ruler's quality lies in the straightness of its measuring surface, determining its accuracy level. Aligning manufacturing and selection processes with specific accuracy standards aids in standardizing equipment precision and tool tolerance values. This systematic approach ultimately enhances manufacturing and usage accuracy across diverse applications.
