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.

The solution from HEULE reduces the processing time and improves the process capability. The workpiece is not to be moved in any case in order to keep the tolerance simply and safely.

The customer is very satisfied by the result and the achieved time savings. The high spindle speed reduces the fluttering of the blade due to the interrupted cut considerably.

Our customer has been machining the connecting rods manually for years.

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 a 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.

The production of bores and counterbores in the aluminium wheel is requiring 4 different tools. In addition, the production sequence includes a turning of the workpiece. Time and effort invested into the maintenance and the down time for the readjustment of the repaired tools are considerable. The high tool costs for the existing tools and the not assured process capablity were the reasons why the present production method has been questioned.

The new approach by HEULE proposes to unify all four existing tools into a single one. To do that HEULE combines two tool systems and their advantages in an ideal way. The new tool eliminates the time-consuming turning of the workpiece.

The customer is very pleased by the result and the achieved time savings. When combining different processes in one tool, it is important to adjust the working feed and also the speed of the countersinking and  the chamfering. An internal cooling system is absolutely necessary to flush the chips away. HEULE is opting for an utmost sturdy tool design in order to avoid vibrations. Herefore, the given space sets out the framework for the dimensioning of this special combination tool. 
The HEULE special tools are renowned for their simplicity and their process capability. Furthermore, all tools are designed consistently that no turning of the workpiece is required. The tools machine the front of the workpiece just as well as the back. The blades of the designed tool start to cut only when they touch the work piece. Tool repair and blade change are carried out easily and without any readjusting. These typical HEULE features guarantee extremely short machine down times.
