- 【Bullet Point 1】: Complete & Precise Measurement Standard This surface roughness comparators set serves as the definitive on-the-spot reference. The 30 hardened steel blocks cover the entire Ra 0.05-12.5μm (µm) range, providing instant tactile and visual comparison to verify if machined parts meet your design specifications—no batteries or complex electronics needed. It's an essential tool replacement for Mitutoyo or Starrett gauge users who require reliable, physical standards.
- 【Bullet Point 2】: Industrial-Grade Durability for Daily Use Forged from 45# premium carbon steel and treated with a protective oil coating, each roughness test block set is built to withstand the rigors of the shop floor. Their exceptional hardness and wear resistance ensure the surface standards remain accurate for years, making them a cost-effective, long-term investment for your quality control station, replacement for frequently worn-out comparators.
- 【Bullet Point 3】: Intuitive Visual & Tactile Assessment Engineered for clarity and speed, each block in this Ra microfinish comparator is permanently etched with its Ra value. The logical progression from smoothest to roughest allows for rapid visual matching and tactile feel assessment. This enables machinists and inspectors to make immediate pass/fail decisions, dramatically speeding up inspection workflows.
- 【Bullet Point 4】: Universal Application Across Machining Processes This versatile surface finish comparator blocks set is designed for evaluating six key surface finishes: horizontal/vertical milling, turning, plain/external grinding, and flat lapping. It is the trusted machining surface finish gauge for quality assurance professionals in automotive, aerospace, metal fabrication, and precision engineering workshops.
- 【Bullet Point 5】: Complete Professional Kit for Immediate Use You will receive the complete 30-block comparator set, meticulously organized in a protective case. It arrives ready for immediate use in daily quality checks, equipment calibration, and staff training. This all-in-one kit eliminates the guesswork from surface finish verification, ensuring consistency and upholding the highest manufacturing standards.
