Surface comparison plates — 30-piece reference set from Metav IndustryLine, covers Ra references for turning, milling and grinding

Surface comparison plates provide a tangible way to compare and classify surface finishes across common machining processes, acting as fast visual and tactile references for production and quality checks.

• 30-piece set for standardised surface comparison
• Ra coverage from 500 to 0.05 µm
• For turning, milling, grinding and lapping checks
• Compact, workshop-ready reference plates

Faster visual control of surface quality for routine production

The set functions as a practical reference collection that translates numeric roughness values into visible and tactile examples. By comparing a workpiece directly with the plates, shop-floor staff can make quicker pass/fail decisions without immediate reliance on profilometers. The plates support basic process control and first-line inspections, reducing downtime caused by ambiguous surface assessments and improving throughput in small-batch and series production.

Clear mapping between processes and roughness classes

The plates cover process-oriented roughness classes, with Ra steps provided for turning, vertical/horizontal milling, plan and round grinding, and lapping. The set lists arithmetic roughness ranges (Ra) and equivalent amplitude values for the typical processes, which helps to interpret machine settings and tool condition. This direct mapping simplifies communication between setup, quality and production teams by linking machining parameters with expected surface outcomes.

Practical benefits for workshop and quality departments

The compact 30 plates fit into bench kits and inspection trolleys, enabling repeatable checks during setup and run-in phases. They are especially useful for incoming inspection, quick tool comparisons and operator training, where a standardised visual language for surface texture speeds decisions. Because the examples span coarse to very fine finishes, the collection supports a broad scope of parts—from turned housings to finely lapped faces—without excessive handling or instrument changeover.

Durable reference, clear identification and easy integration

Each plate is lightweight and marked for quick identification; the set is supplied as a complete reference pack for straightforward storage and retrieval. The plates are intended for comparative assessment and process alignment rather than as a substitute for traceable profilometer measurements. For buyers seeking a reliable supplier, Metav IndustryLine provides consistent availability and a broad portfolio of metrology aids that integrate with workshop quality systems.
