Quality Testing, Calibration Fixtures, Machining Capabilities
Based on the experience of our specialists, we are confident that CNC multi-axis machining centers and modern coordinate measuring machines (CMM) will allow us to achieve the desired quality and, at the same time, take full advantage of CNC machining the Calibration Fixtures for Quality Testing. With a proven performance for thousands of calibration cycles, each part, be it a single-parameter measuring block or complex systems with thermal stabilization, multi-parameter reference standards or master calibration assemblies, is engineered to optimal criteria.
For reference surfaces, we do precision CNC milling, then do high-precision grinding for any dimensional standards with tolerances of ±0.005 mm. Additionally, we surface-ground for optical flatness to attain λ/4 at the 633 nm wavelength to do specialized lapping for ultra-smooth reference surfaces exhibiting roughness values under 0.1 Ra microns. Thermal stability testing alongside CMM dimensional verification is also performed. Each calibration fixture is created from tool steel (A2, D2) for both wear resistance and dimensional stability, stainless steel 17-4 PH for its corrosion resistance and hardness properties of 44 HRC, tungsten carbide for its extreme hardness and thermal stability, or specialized items like ceramic gauge blocks (ZrO₂) that have ultra-low thermal expansion and high wear resistance, granite for its exceptional flatness and thermal mass, and Invar 36 for its precision zero thermal expansion coefficients for metrology applications. For different calibration applications, we provide excellent dimensional accuracy of ±0.005 mm, superior thermal stability with the expansion coefficient ranging from 0.5 to 12 µm/m·°C (depending on the material), and surfaces finishes of 0.05 to 0.8 Ra microns, across temperature operating ranges 18°-22°C with drift below ±0.2 µm/°C.

FAQs: Calibration Fixtures for Quality Testing Applications
Calibration fixtures refer to precision-engineered reference standards employed to confirm and adjust measurement devices, dimensional gauges, and inspection systems within the scope of semiconductor manufacturing. The calibration fixtures include NIST traceable gauge blocks, reference plates, and standards for thread gauges that exhibit close dimensional tolerances. These are: gauge blocks to ±0.0005 mm, reference plates ±0.010 mm for CMM, thread gauge pitch diameters to ±0.005 mm, and ISO 4287 traceable surface standards. Calibration of these fixtures exhibits stability and thermal drift of less than ±0.5 µm/°C, planar deviations of ±0.003 mm in 100 mm spans, and overall non-parallel tolerances of ±0.005 mm for the reference surfaces. Recalibration periods exceeding five years are available for certification to national and international standards.
Tool is distinguished in the industry for it`s excellent wear resistance and has a hardness level of 62 HRC after heat treatment and in dustrial level heat treatment it has a hardness level of 62 HRC, it has low distortion during thermal cycling, is good for machining when hard, can achieve surface finishes in microns, and has a thermal expansion coefficient of 11.5 micro m/ m.degrees celcius which is low enough for it to be suitable for controlled ambient conditions. Tungsten carbide gives good and satisfying operational wear and thermal expansion, and is corrosion resistant. Invar 36 has the lowest thermal expansion coefficient of 1.2 micro m/ m.dregrees celcius and is good for metrology, and is good for calibration standards. Invar 36 has a drift of +/- 0.1 microns per degree celcius as a low drift measurement. Invar 36 had a significant stability for calibration standards over time which makes it perfect for master calibration standards. Invar 36 has a significant repeatability over time which has a thermal expansion coefficient with a measurement system of +/- 0.5 ppm/ degree celcius.
Multi-axis CNC milling can construct intricate reference geometries with a total dimensional accuracy of ±0.008 mm and surface finishes (notable for their smoothness) in the region of 0.8 Ra microns. Precision grinding on critical measurement surfaces provides the following tolerances: ±0.005 mm on the dimensioning and ±0.003 mm on the flatness in the critical surfaces. Additionally, surface grinding yields optical-quality flatness of λ/4 for master reference standards at 633 nm. In the process of cylindrical grinding, diameter tolerances of ±0.003 mm with a corresponding cylindricity of 0.002 mm are achieved. In wire EDM (Electrical Discharge Machining) complex profiles and intricate calibration features embedded in hardened materials are made with tolerances of ±0.005 mm. Precision lapping furnishes ultra-flat surfaces with flatness of 0.001 mm per 100 mm and surface roughness is below 0.05 Ra microns. Diamond turning produces unrivaled (mirror) surfaces for optical metrology with roughness below 0.025 Ra microns. For multi-dimensional reference standards, coordinate grinding provides and guarantees the following, in normal engineering parlance, that is, ±0.003 mm of parallelism, ±5 arc-seconds of perpendicularity.
We maintain dimensional accuracy of ±0.005 mm for reference features ensuring measurement traceability to national standards, surface flatness of ±0.003 mm over 100 mm span for gauge block and master plate applications, parallelism between opposing surfaces within ±0.003 mm for thickness standards and parallel blocks, perpendicularity within 5 arc-seconds for angle references and square standards, cylindricity of ±0.002 mm for pin gauges and cylindrical references, concentricity within ±0.005 mm for rotational calibration features, and surface finish from 0.05 to 0.8 Ra microns depending on calibration application. These tolerances support measurement system accuracy verification within ±0.001 mm, gauge repeatability and reproducibility (GR&R) studies with variation below 10 percent, thermal stability maintaining dimensional accuracy during ±1°C temperature changes, and calibration certification traceable to NIST, PTB, or equivalent national metrology institutes for 3 to 5 year calibration intervals.
Yes, we provide rapid prototyping to verify fit and test assembly, with same-day CAD-to-part capability available for critical projects. For custom automation cells and research platforms, we perform low-volume production of 20 to 500 brackets. For standardized robot models, we perform high-volume production of thousands to tens of thousands of brackets annually, incorporating complete dimensional inspection, flatness verification, and material certifications.
