Operational Guidelines & Care
- Clean reference faces with lint-free cloth and light machine oil before and after each use cycle
- Store in a dry, temperature-stable environment to prevent thermal expansion and surface corrosion
- Avoid dropping heavy workpieces directly on ground surfaces to preserve dimensional accuracy
- Inspect tapped hole grid periodically for thread damage and apply anti-seize compound during reassembly
- Re-verify squareness annually using precision dial indicators or certified gauge blocks
- Transport using designated lifting points or padded cradles to prevent edge chipping or frame distortion
Material & Construction Quality
- Manufactured from high-grade alloy steel selected for exceptional rigidity and wear resistance
- All reference surfaces undergo precision grinding to achieve consistent surface finish and flatness
- Through-hardening process ensures uniform hardness distribution across the entire structural block
- Reinforced internal geometry prevents flex or torsion during high-force clamping and cutting operations
- Factory calibrated to meet ± 0.005 mm tolerance standards before leaving the Crystal manufacturing facility
- Designed for heavy industrial environments while maintaining metrology-grade reference stability
Industrial Applications
- Squaring and securing complex raw castings or machined stock on mill tables, drills, and surface grinders

- Part of the Crystal AA-274 series, engineered to maintain ± 0.005 mm accuracy under load
- Available in standard dimensions like 100 x 100 x 115 mm, scaling across the product family for diverse workholding needs
Frequently asked
Can this angle plate be used with magnetic chucks or vacuum fixtures?
Yes, the flat reference faces are compatible with magnetic chucks, vacuum tables, and custom fixture plates.
How often should the 90° accuracy be recalibrated?
We recommend annual verification with dial indicators or gauge blocks, depending on shop frequency and load conditions.
Is the tapped hole pattern standardized across the AA-274 series?
The multi-point clamping matrix follows industry-standard spacing, though exact pitch varies by plate size in the range.
What is the maximum recommended clamping force?
The solid right-angle frame is engineered to withstand standard machining loads without twisting or permanent deformation.
