Add rounded corners in metal plate Angle place, make it not sharp, increase their sexual contact.
In order to remove the parts because of the machining burrs, also in order to facilitate part assembly, generally at the end of the parts made of Chamfering is 45 ° more, also can be made into 30 ° and 60 °.
