## Description

Features:* For Rapid quality sampling of batch workpieces in industrial production, efficient screening of roughness defective products.* Quickly judge the adaptability of parts in the absence of on-site installation and maintenance scenarios of for instruments.* for Unify standards for acceptance by both supply and demand parties to reduce disputes caused by detection differences.* Help understand the state corresponding to different roughness parameters in teaching and training.* Before spraying, electroplating and other processes, assist in judging whether the workpiece meets the pretreatment requirements.Specifications:*Part name: roughness comparison sample* Material:steel*Size: 8*6*3cm* Color: As the picture*Optional specifications：* Lathe Ra0.8-6.3um wooden box 4pcs* Vertical milling Ra0.8-6.3um wooden box 4pcs* Flat milling Ra0.8-6.3um wooden box 4pcs* Flat grinding Ra0.1-0.8um wooden box 4pcs* External grinding Ra0.1-0.8um wooden box 4pcs* Grinding Ra0.025-0.1um wooden box 3pcs* Planer Ra0.8-6.3um wooden box 4pcsPackage Content:1 x roughness comparison sample

## Features

- Roughness: For quality sampling in industrial production, this steel comparison test block set includes 4pcs lathe (Ra0.8-6.3um), 4pcs vertical milling (Ra0.8-6.3um), 4pcs flat milling (Ra0.8-6.3um), 4pcs flat grinding (Ra0.-0.8um), 4pcs external grinding (Ra0.-0.8um), 3pcs grinding (Ra0.025-0.um), and 4pcs planer (Ra0.8-6.3um), all stored in a protective wooden box for organized use and long-lasting durability
- Comparison Test Block: Helps efficiently screen roughness defective products without on-site instruments by enabling quick tactile and visual inspection, for verifying finish compliance during batch processing or incoming material checks
- Roughness Test Block: Unifies acceptance standards between suppliers and buyers to reduce disputes caused by measurement variations, especiuseful in manufacturing environments where precise Ra value consistency is required across teams and facilities
- For Roughness Evaluation: Assists in determining if workpieces meet pre-treatment requirements before spraying, electroplating, or coating processes, with clearly labeled samples ranging from coarse to ultra-fine finishes (Ra0.025-6.3um) for accurate reference
- Inspection Gage Solution: Supports teaching and training applications by illustrating the physical state corresponding to different roughness parameters; size 8*6*3cm per sample, steel construction ensures stable over, as shown with slight variation due to and screen settings
