HEULE X-BORES
Deburring of Cross Bores.
With X-BORES HEULE takes up the challenge to provide solutions for the automated deburring of cross bores. Existing technologies soon run into their limits. The deburring by means of a defined cutting edge in a chip making process brings up major advantages.
Modern components increasingly have more complex geometries and are made of new materials or material combinations. Furthermore, the demans on the deburring quality, the process capability and the efficiency that have to be met are rising continuously.
HEULE as an experience problem solver offers customer-optimized solutions based on four different tool systems:
SNAP – The economic chamfering tool.
Economic front and back chamfering in One Operation, with very easy blade changes.
The SNAP tool is an efficient front and back chamfering tool that is easy to use and which allows quick blade changes, making it a convenient solution for any manufacturing environment. Without any need to turn the work piece or to stop the spindle, it removes the burrs and chamfers the edges. The SNAP tool has been designed for automatic operation involving large production lots.
Specifics/Benefits
- Front and back chamfering of bore edges in One Operation.
- Manually exchangeable carbide blade with material-specific coating.
- The compact design ensures easy handling and high process reliability.
- No injury of bore surfaces during penetration of the bore.
- Can be used for bore diameters of 2.0 mm and larger.
Function
The SNAP chamfering blade is held by a spring-loaded control bolt inside the tool body so that it can move. The specially ground SNAP blade for front and back or only back cutting generates the desired chamfer by forward feed. As soon as the defined chamfer thickness has been achieved, the SNAP blade radially enters the tool body. The chamfer thickness and angle are geometrically defined on the SNAP blade and can only be modified by inserting a SNAP blade with different specifications. When it exits the bore, the SNAP blade returns to its home position via the spring-loaded control bolt. A specially designed sliding section prevents the bore from being injured. It is also possible to penetrate reamed bores without risk of damage. The result is exceptional front and back chamfering in One Operation.
Operation method
The operation is very simple. The tool blade is moved by rapid motion to a point ahead of the top bore edge. The top bore edge is machined by forward feed and with the working RPM. When the chamfer thickness has been achieved, the SNAP blade automatically enters the tool body. Now the tool moves by rapid motion and without stopping the spindle through the bore until the SNAP blade has again been extended at the back of the work piece. Now the back bore edge is chamfered by backward feed. When the chamfer has been produced, the tool moves out of the bore again by rapid motion.

Proposed solution by HEULE Werkzeug AG
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.
Benefits of the solution
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.

Proposed solution from HEULE Werkzeug AG
This application represented a challenge to HEULE Werkzeug AG because of the relatively small bore as well as the height of the uneveness. The use of the standard blade with a countersink angle of 90° was not sufficient for this special application in order to make all of the contour of the bore edge absolutely free of burrs. A special blade with a 60° countersink angle has been developed for this reason. This blade enabled a deeper deburring with the same deburr diameter. Hence, a constantly even broken edge breaking and a clean surface became reproduceable.
Benefits of the solution
The customer is satisfied by the result and the achieved process capability. Having passed the approval procedure successfully, the tool has been released for serial production and is operated on two production line during 24 hours per day. The customer is excited about the reliability and the simple handling of the SNAP2 tool system.
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.

Counterbore Tools from HEULE to reduce process time and improve efficiency
Cylinder head / Back Spot Facing Tool
Cycle time - the decisive factor
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.
Customer application
The manufacture of countersinks, in particular screw head countersinks, are carried out mostly by back machining and are very time consuming. Either the workpiece is machined on the front surface which entails a turning of the workpiece. After the turning, it is evident that readjusting is inevitable and the time needed has tripled - or the machining is done backward. Most commonly a screw-on-type countersink or counterbore tool is used. The issue here is that - having to machine serveral hundreds of bores - all bores have to be approached individually because the countersink cap has to be fixed first every single time. Needless to mention that this takes a lot of time.
The high amount of time invested in each bore and the lacking process capability have led to rethinking this process.

Cycle times - the decisive factor
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.
Customer application
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.
Proposed solution by HEULE Werkzeug AG
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.
Benefits of the solution
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.
