HEULE has been reducing cycle times in the automotive industry successfully for over 30 years now. Today, car manufacturers ask for simple and process capable tool system. Terms like "time saving activities", "labor costs saving“ and "CIP continuous improvement process“ are common practice in the automotive industry
Our customer has been machining the connecting rods manually for years.
|Deburring size||Ø63.5 mm|
The HEULE proposal stipulates a cassette solution with the COFA tool. The standard COFA cassette can be adapted easily to large bore diameters by using a customized tool holder. This method gives the freedom to use the standard cassette also for other deburring applications.
The burrs will be removed at the front and at the back without any problems. Due to the unevenness of the bore edge, the radial deburring will be slightly irregular.
The connecting rod is clamped on an undefined surface. As a result, the deburring surface is also undefined which is asking necessarily for a spring-guided deburring system that compensates for the variance.
The COFA blade does not hurt the already finished bore surface when traversing the hole. It is recommendable to apply low cutting values in order to allow the COFA blade to adapt to the contour.
