Precision Wafer Edge Geometry
Sharp square-edged master split wafers scrape against the cylinder plug edge during shear line rotation, creating abrasive brass burrs.
Precision Micro-Chamfering
- Edge Radius: Master wafers undergo vibratory barrel tumbling or precision CNC chamfering to produce $0.05\text{ mm}$ edge radii.
- Smooth Rotation: The rounded edges glide smoothly across the shear line without gouging the brass chamber bore.
Frequently Asked Engineering & Selection Questions
Q1: Why must master wafers have rounded chamfered edges?
Sharp-edged wafers scrape the brass chamber walls under rotational torque; rounded edges prevent burrs and keep the lock turning smoothly.
