ACCRETECH SURFCOM NEX Contact Profilometer for Surface Roughness and Contour Measurement

Overview

The ACCRETECH SURFCOM NEX is a high-precision, motorized contact profilometer engineered for comprehensive surface topography characterization in R&D laboratories, quality control environments, and precision manufacturing facilities. Utilizing a diamond-tipped stylus operating under controlled force (typically 0.75 mN to 4 mN, configurable per ISO 3274 and ISO 11562), the system measures vertical displacement with sub-nanometer resolution while traversing surfaces at linear speeds ranging from 0.01 to 10 mm/s. Its core measurement principle—stylus-based profilometry—relies on mechanical tracing of surface asperities to generate analog voltage signals, which are digitized and processed to extract standardized roughness parameters (e.g., Ra, Rz, Rq, Rsk, Rku), waviness profiles, and full 2D/3D contour geometry. Designed for metrological traceability, the SURFCOM NEX integrates a thermally stable granite base, air-bearing linear stage, and high-resolution encoder feedback (≤ 0.1 nm interpolation resolution), ensuring repeatable measurements compliant with ISO 4287, ISO 4288, ISO 13565, and ASME B46.1 standards.

Key Features

• Modular dual-sensor architecture supporting simultaneous roughness and contour analysis on a single scan pass
• Motorized Z-axis with 10 mm vertical travel range and programmable lift/lower speed for automated multi-point inspection
• Interchangeable stylus holders accommodating standard 2 µm radius diamond tips (ISO 3274) and specialized geometries (e.g., 5 µm radius for deep groove profiling)
• Integrated vibration isolation platform with active damping, reducing environmental noise influence below 1 Hz
• Real-time scanning feedback via high-speed digital signal processing (DSP) engine, enabling on-the-fly parameter calculation and profile preview
• Compliance-ready firmware with audit trail logging, user access levels (admin/operator/guest), and electronic signature support aligned with FDA 21 CFR Part 11 requirements

Sample Compatibility & Compliance

The SURFCOM NEX accommodates flat, curved, and inclined surfaces across diverse material classes—including hardened steels, ceramics, optical glasses, injection-molded polymers, and semiconductor wafers—with sample dimensions up to 300 mm × 300 mm (standard stage) and optional extended stages for larger components. Its low-force stylus operation prevents plastic deformation on soft metals (e.g., aluminum alloys, copper foils) and brittle materials (e.g., silicon nitride, fused silica). All measurement protocols adhere to international calibration frameworks: traceability to NIST and JCSS-certified reference standards is maintained through factory-accredited calibration certificates (ISO/IEC 17025 accredited labs). The instrument meets electromagnetic compatibility (EMC) requirements per IEC 61326-1 and safety standards per IEC 61010-1, ensuring safe integration into GLP and GMP-regulated production lines.

Software & Data Management

SURFCOM NEX operates with ACCRETECH’s proprietary SURFPAK V8 software—a Windows-based platform supporting full data acquisition, analysis, reporting, and database archiving. Key capabilities include automated report generation (PDF/Excel), customizable parameter templates aligned with customer-specific SPC requirements, batch measurement scripting (VBScript integration), and raw profile export in ASCII, CSV, or ISO-standard X3P format. Data integrity safeguards include time-stamped measurement logs, operator ID tagging, version-controlled analysis algorithms, and encrypted local storage. Optional cloud synchronization enables secure remote review and cross-site comparison of measurement histories, facilitating enterprise-wide metrology harmonization.

Applications

• Quantitative verification of machined surface finish in aerospace turbine blades and medical implant substrates
• Waviness evaluation of precision-ground bearing races and optical lens molds
• Step height and film thickness validation in MEMS fabrication and thin-film coating processes
• GD&T-compliant form error analysis (flatness, straightness, circularity) on critical sealing surfaces
• Root cause investigation of tribological failure modes via correlation of roughness parameters with wear test results
• Validation of additive manufacturing post-processing efficacy (e.g., shot peening, electropolishing)

FAQ

What stylus tip radius options are supported?
Standard configuration includes a 2 µm radius diamond stylus conforming to ISO 3274; optional 5 µm and 12.5 µm tips are available for high-aspect-ratio features or low-noise averaging.
Can the SURFCOM NEX measure inside diameters or narrow grooves?
Yes—using optional miniature probe modules (e.g., 1.5 mm diameter shaft with 90° angled tip), the system achieves profiling in bores down to Ø3 mm and grooves ≥ 0.3 mm wide.
Is calibration certification included with shipment?
Each unit ships with a JCSS-accredited calibration certificate covering vertical scale linearity, stylus tip geometry verification, and reference standard traceability to national metrology institutes.
Does the system support automated multi-location measurement?
Yes—the integrated CNC motion controller supports programmable XY positioning (via optional motorized stage) and sequential roughness mapping across grids of up to 100×100 points.
How is software validation handled for regulated industries?
SURFPAK V8 is supplied with IQ/OQ documentation packages, installation qualification checklists, and pre-validated analysis algorithms compliant with ASTM E2500 and Annex 11 guidelines.
