About Edge Breaking

Standard Values for Edge Breaking

Model Example	Part Example	Standard Value
Model Example	Part Example	Light Edge Breaking	C/R Edge Breaking Option Name: “All Around R0.2 or Larger / Corner C1”
	①Corner	Not Available	Chamfer model corners with C1 Corners less than 30° or greater than 170° are excluded Image of chamfered corner
	②Edges of sheet metal surfaces	Finish burrs and flash generated during sheet metal punching to approx. R0.1	Finish burrs and flash generated during sheet metal punching to R0.2 or larger (approx. R0.3)
	③Narrow Slit Area	No burrs or flash of 0.1 mm or larger	Finish burrs and flash to approx. R0.1
	④Narrow width, small holes	No burrs or flash of 0.1 mm or larger	Finish burrs and flash to approx. R0.1

There is a possibility of minor scratches on the appearance because a double-sided deburring machine is used for eliminating 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.

Edges of sheet metal surfaces are chamfered to R0.2 or larger using a double-sided deburring machine, and product corners are chamfered to C1 by laser processing.
Fine scratches may occur on the surface during Edge Breaking of edges of sheet metal surfaces.
C/R Edge Breaking is not available when combined with engraving service, as characters may become faint.

Caution

Cases Where Edge Breaking is Restricted

Since Edge Breaking is performed by a deburring machine before bending, narrow slit areas will have a fine chamfer finish (approx. R0.1).

Caution

Cases Where Corner Edge Breaking is Not available

1. Model corner includes curves

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