Precision Fixtures & Tooling
Precision-engineered solutions for every need. Custom tailored fixtures designed for unique manufacturing requirements, offering flexible designs that adapt to different applications and engineered to withstand rigorous manufacturing environments.
Technical Definition & Operating Principle
Precision inspection fixtures and tooling are dedicated quality-control holding and measurement assemblies engineered to verify the geometric accuracy of complex manufactured workpieces. Designed directly from customer 2D component drawings and 3D CAD models, AKIRA fixtures utilize high-grade tool steel (HCHCr and OHNS) hardened to 60–62 HRC and cryogenically stabilized for lifelong dimensional integrity. Workpieces are located against precision ground datum pins and resting pads using manual toggle or pneumatic cylinder clamps, ensuring repeatable part orientation without introducing mechanical deformation. Modular mounting brackets support dial test indicators, pneumatic air nozzles, and electronic LVDT inductive probes for multi-point dimensional checking on shop-floor machining lines. Every AKIRA fixture undergoes comprehensive Coordinate Measuring Machine (CMM) verification prior to dispatch, with complete inspection reports and Gage Repeatability and Reproducibility (Gage R&R) studies provided for automotive OEM audit compliance.

Frequently Asked Technical Questions
- What materials and hardening treatments are used in AKIRA inspection fixtures?
- AKIRA fixtures are constructed from premium tool steels including High Carbon High Chromium (HCHCr) and Oil Hardened Non-Shrinking (OHNS) steels, heat-treated and hardened to 60–62 HRC with sub-zero cryogenic stabilization to prevent long-term dimensional drift.
- How is Gage R&R compliance verified for custom fixtures?
- Every fixture undergoes 100% Coordinate Measuring Machine (CMM) dimensional verification and a rigorous Gage Repeatability and Reproducibility (Gage R&R) study with 10 parts, 3 operators, and 3 trials, guaranteeing a total Gage R&R of under 10% for critical automotive dimensions.
- How are component datum points established for complex castings?
- AKIRA fixtures locate workpieces using the classic 3-2-1 principle with precision-ground rest pads and diamond/round locating pins aligned to the primary machining datums specified on the customer's 2D/3D component drawings.
- What is the typical manufacturing and validation lead time for custom fixtures?
- Custom inspection fixtures typically take 3 to 6 weeks from CAD design sign-off through CNC machining, cryogenic heat treatment, Coordinate Measuring Machine (CMM) verification, and Gage R&R sign-off with customer master parts.
