The key advantage of the SJ220 is its portability. Check critical parts without moving them, increasing inspection efficiency and throughput. It stores thousands of measurements and seamlessly transfers data to a PC for reporting and SPC analysis, ensuring full traceability.

As an ISO 1997 compliant instrument, the Mitutoyo SJ220 guarantees reliability you can trust. For ensuring product quality, from automotive to aerospace, this Portable Surface Roughness Tester is an indispensable tool for maintaining the highest standards.

One Machine, Two Critical Measurements

Manufacturers constantly seek ways to streamline their quality control (QC) process without sacrificing accuracy. The FORMTRACER Avant delivers a powerful solution. This cutting-edge hybrid system measures both surface roughness and contour features using a single platform. You eliminate the need for two separate instruments, immediately saving space, setup time, and capital investment.

This innovative design significantly improves efficiency. You simply exchange the detector to switch between contour and roughness analysis. The system recognizes the detector automatically, minimizing user error and maximizing workflow speed. This rapid conversion capability ensures you analyze complex parts faster than ever before.

High-Speed Performance Defines the Avant Series

Time is money in modern production environments. The FORMTRACER Avant boasts best-in-class drive speed. The X-axis (drive unit) moves at up to $80\text{ mm/s}$, and the Z2-axis (column) moves at $30\text{ mm/s}$. The instrument drastically reduces the total measurement time. Mitutoyo also minimized the positioning distance before data acquisition to an industry-leading $0.05\text{ mm}$. This enables precise, quick analysis of edges and narrow features where measurement access is often difficult.

The Avant offers a cable-less design and an X-axis inclinable drive unit (±45∘ range). This eliminates the need for complex, time-consuming jigs for inclined surfaces. You achieve superior operability and maximize productivity for every single workpiece.

The FORMTRACER Avant uses precision arc scale technology for direct reading of the stylus trajectory. This ensures high accuracy across a wide range, delivering reliable data for complex components like gears, screw threads, and tablet molds.

Invest in the FORMTRACER Avant today. Give your inspection process the speed, versatility, and precision it truly deserves.

Mastering Quality Control: The Surface Roughness Comparator

In precision manufacturing, "smooth enough" is rarely sufficient. Achieving the correct finish is vital for part functionality and longevity. This is where the surface roughness comparator becomes an essential tool on the shop floor.

What is a Surface Roughness Comparator?

A surface roughness comparator is a reference standard used to estimate the texture of a machined surface. It consists of a plate featuring several segments. Each segment represents a specific roughness value, typically measured in $Ra$ (Arithmetical Average) or $Rz$ (Mean Roughness Depth).

How to Use It Effectively

Using a comparator is straightforward yet highly effective. It relies on two primary methods:

1. Visual Inspection: You place the comparator next to your workpiece under good lighting. By comparing the light reflection and pattern, you can estimate the finish.

2. Tactile Comparison: This is often more accurate. You run a fingernail across the workpiece and then across the comparator segments. If the "feel" matches, the roughness is likely within that specific range.

Why Your Shop Needs One

While digital profilometers provide exact data, they are expensive and delicate. Comparators offer a cost-effective alternative for quick checks. They help operators monitor tool wear and ensure parts meet engineering specifications before moving to the next production stage.

Using these tools reduces scrap rates. It also ensures consistency across different batches. Whether you are milling, turning, or grinding, a comparator provides a reliable baseline for quality.

Conclusion

A surface roughness comparator is a small investment that yields significant results. It bridges the gap between raw machining and precision engineering. By integrating these into your workflow, you maintain high standards and keep customers satisfied.
