Sprocket Wheel

Descripción

HALLA Industries Co. Ltd. - a subcontracting company to the automotive and the fittings industry - is located in South Korea. Among the components produced are flanges, sprockets and drive shafts.

Previously, the customer used a full carbide drill for the hole and a front and back deburring tool for removal of the burrs. The cycle time for all 12 bores amounted to 320 seconds. Since the deburring tool failed to produce a consistent chamfer, the sprockets had to be reworked manually outside of the machine.
