Four processing requirements that are easy to overlook<\/h2>\n<h3>Cutting and edge finish<\/h3>\n<p>Edge chips and microcracks can affect performance under thermal cycling or mechanical load. A drawing should define allowable chipping, chamfer, edge condition and inspection method rather than merely asking for \u201csmooth edges.\u201d<\/p>\n<h3>Holes, slots and stress concentration<\/h3>\n<p>Openings and notches change local stress. For laser or CNC features, assess diameter, spacing, minimum edge distance, thickness and final assembly from the drawing. The glass grade alone cannot justify a machining-limit promise.<\/p>\n<h3>Residual stress and annealing<\/h3>\n<p>Some thermal or machining routes may introduce residual stress. The 560 \u00b0C annealing point is a material datum, not a universal annealing recipe. Whether to anneal, the dwell and cooling profile, and stress inspection depend on part geometry and actual equipment.<\/p>\n<h3>Mounting method<\/h3>\n<p>Rigid clamping, local temperature differences and mismatched frame expansion can add stress to glass. Support points, clearance, interface pads, load and cycling belong in the material-selection review.<\/p>\n<h2>8.

Four processing requirements that are easy to overlook<\/h2>\n<h3>Cutting and edge finish<\/h3><p>Edge chips and microcracks can affect performance under thermal cycling or mechanical load. A drawing should define allowable chipping, chamfer, edge condition and inspection method rather than merely asking for \u201csmooth edges.\u201d<\/p>\n<h3>Holes, slots and stress concentration<\/h3><p>Openings and notches change local stress. For laser or CNC features, assess diameter, spacing, minimum edge distance, thickness and final assembly from the drawing. The glass grade alone cannot justify a machining-limit promise.<\/p>\n<h3>Residual stress and annealing<\/h3><p>Some thermal or machining routes may introduce residual stress. The 560 \u00b0C annealing point is a material datum, not a universal annealing recipe. Whether to anneal, the dwell and cooling profile, and stress inspection depend on part geometry and actual equipment.<\/p>\n<h3>Mounting method<\/h3><p>Rigid clamping, local temperature differences and mismatched frame expansion can add stress to glass. Support points, clearance, interface pads, load and cycling belong in the material-selection review.<\/p>\n\n<h2>8.
