About Edge Breaking

Edge Breaking Standards

Model Examples	Feature Example	Standard Values
Model Examples	Feature Example	Light Edge Breaking	Heavy Edge Breaking
	①External Corner	None	External Corners chamfered C1mm. Corners less than 30° or greater than 170° are excluded. External Corner Chamfering
	②Sheet surface Edges	Remove burrs and flash and break edges to approx. R0.1	Remove burrs and flash and break edges to R0.2 or larger (approx. R0.3)
	③Narrow Slit Area	No burrs or flash of 0.1mm or larger	Finish burrs and flash and Break Edges to approx. R0.1
	④Narrow cutouts and small holes	No burrs or flash of 0.1mm or larger	Finish burrs and flash and Break Edges to approx. R0.1

There is a possibility of minor scratches on appearance surfaces from the double-sided deburring machine used to eliminate burrs.
Edge breaking and engraving cannot both be specified on the same model. The edge breaking process can cause the engraving to fade.
Transparent resin parts will have the edge breaking finish as standard.

Sheet surface edges are broken to R0.2 or larger using a double-sided deburring machine, and external corners are chamfered to C1 by laser cutting.
Fine scratches may occur on sheet surfaces when Edge Breaking sheet surface edges.
Heavy Edge Breaking is not available with engraving, as characters may become faint.

Caution

Cases Where Edge Breaking is Restricted

Since Edge Breaking is performed by a deburring machine before bending, narrow slits will have a fine edge break finish (approx. R0.1).

Caution

Cases where External Corner Chamfering is Not Applicable

1. Model corner includes curves

2. Acute angles less than 30° and obtuse angles greater than 170°
