Checking Fixtures FAQ
1. What is the typical lead time for checking fixtures?
Standard checking fixtures typically have a lead time of 3-4 weeks from order confirmation. For custom configurations requiring specialized components or materials, the lead time may extend to 6-8 weeks. We offer expedited production options for urgent requirements, with a 30% premium fee reducing lead times by up to 50%.
2. How do I maintain my checking fixtures for optimal performance?
Regular maintenance includes weekly cleaning with isopropyl alcohol to remove contaminants, monthly verification of alignment using master samples, and annual recalibration by certified technicians. Store fixtures in controlled environments (40-70% humidity, 60-80°F) when not in use. Avoid impacts or excessive force during operation that could affect measurement accuracy.
3. Can checking fixtures be modified after initial production?
Our modular checking fixtures allow for post-production modifications with 85% of models supporting at least three major revisions. Common modifications include adding new measurement points (typically $75-$200 per point), adjusting clamping mechanisms ($150-$400), or expanding the base platform (20-50% of original fixture cost). Submit your modification requirements for a detailed engineering assessment.

Material Options Comparison
Selecting the right material is crucial for checking fixture performance:
| Material | Advantages | Limitations | Ideal For |
|---|---|---|---|
| Aluminum (6061-T6) | Lightweight, corrosion resistant, cost-effective | Lower impact resistance | High-volume production |
| Stainless Steel | Excellent durability, thermal stability | Higher cost, heavier | Precision aerospace applications |
| Carbon Steel | High strength, impact resistant | Requires protective coating | Heavy industrial components |
| Reinforced Polymer | Non-conductive, chemical resistant | Limited temperature range | Electronics manufacturing |
Additional Checking Fixtures FAQ
4. What certification standards do your checking fixtures meet?
Our checking fixtures comply with ISO 9001:2015 quality management standards and are manufactured according to ASME Y14.5-2018 dimensional tolerancing specifications. Each fixture ships with a certificate of conformance documenting material certifications, measurement system analysis results, and accuracy verification data. Industry-specific certifications (IATF 16949 for automotive, ISO 13485 for medical) are available upon request.
5. How do you ensure measurement accuracy across multiple checking fixtures?
We employ a master fixture calibration system where all production checking fixtures are verified against certified master components. Our quality process includes statistical process control (SPC) monitoring with CpK > 1.67 for critical dimensions. For multi-fixture applications, we offer matched set services guaranteeing <0.0015" variation between fixtures through coordinated manufacturing and validation processes.
6. What support services accompany checking fixture purchases?
All checking fixtures include comprehensive support: 24-month warranty covering manufacturing defects, free initial operator training (on-site or virtual), lifetime technical support, and discounted recalibration services. For enterprise customers, we provide dedicated engineering contacts, preventive maintenance programs, and inventory management solutions for fixture components.
