The combination of a compact six-piece surface reference set, clear Ra grading and lightweight handling supports faster shop-floor decisions and consistent process control; ideal where repeatable turning finishes must be checked quickly. Order the set directly via Metav Werkzeuge or consult the Metav advisors for application-specific guidance.

Surface comparison plates "Turning" — six-piece reference set for turned finishes (Ra 12.5–0.4 µm) — Metav IndustryLine

A surface comparison plate set "Turning" for immediate visual and tactile assessment of turned surface roughness across common production grades.

• Six-piece set for turned surface comparison
• Covers Ra 12.5–0.4 µm (500–16 µin)
• Lightweight and portable at 0.2 kg
• Suitable for workshop and quality control environments

Fast verification of turned surface quality on the shop floor

A compact set of reference plates enables quick, non-instrument checks that complement tactile inspection and laboratory measurements. The six surfaces represent standard turned finishes so that comparative assessment becomes a repeatable, documented step in routine quality control. By matching a component’s feel and visual texture against the graded plates, process deviations on the lathe can be identified earlier, reducing rework and scrap. The clear gradation between plates supports objective communication between operator and quality engineer and speeds up corrective action.

Designed for practical use and portable storage

The set is conceived for daily workshop use: durable contact faces with a slim, handled format minimise handling effort, and the total weight of 0.2 kg keeps the set truly portable. Being a compact reference kit, it fits easily into inspection benches or tool drawers and is useful at the machine or at the incoming inspection desk. The six-piece composition means typical turning finishes are covered without excess bulk, improving ergonomics and encouraging regular checks during set-up and tool changes.

Clear specification for process control and staff training

The plates cover Ra values of 12.5, 6.3, 3.2, 1.6, 0.8 and 0.4 µm, which correspond to the commonly used guide values of 500, 250, 125, 63, 32 and 16 µin; this dual notation helps bridge workshop practice and technical documentation. Using reference plates is an established method to align subjective tactile assessment with objective measurement systems. For training purposes, the graded surfaces are an effective way to teach apprentices and operators how feed, speed and tool condition influence final surface finish.

FAQ

What surface grades are included in the set?
The Metav IndustryLine surface comparison plate set includes six grades covering Ra 12.5, 6.3, 3.2, 1.6, 0.8 and 0.4 µm (500–16 µin), intended to represent typical turned finishes.

Can the plates replace a profilometer for quality control?
The plates are designed as a rapid comparative tool for shop-floor verification; they complement rather than replace instrumented profilometry for quantitative measurement.

Is the set suitable for operator training on lathes?
Yes; the graded surfaces are effective for training operators to recognise the influence of tool condition, feed and speed on final surface quality.

How does the set support process control?
By providing fixed reference textures, the set helps standardise subjective inspection, speeding up detection of deviations and informing corrective adjustments during turning operations.
