Deburring – highly efficient processes and methods
The special feature of the engraflexx deburring tools developed by us is the flexible tool spindle bearing. This enables the automated deburring of parts with undefined edges, where the effective workpiece edge deviates from the programmed contour.
As standard, all tool versions are equipped with a cylindrical Weldon shank of 20 mm.
In principle, however, all tools can also be supplied with integrated tool holders such as HSK etc., some of which are even available from stock.

Only the pressure with which the milling cutter is pressed against the workpiece is affected by this adjustment.
The maximum deflection measurement is not affected by it.
No, the position of the router bit remains unchanged with the adjustment of the lateral contact pressure.
Because both deflection directions would mutually influence each other, these are not combined in a single tool.
We offer the two deflection processes in different tool versions: the EC- version with radial deflection principle and the LC- version with the axial spring-preloaded spindle.
There are various parameters such as workpiece contour, material, burr formation etc. which have an influence on the tool selection. This means that a lot of practical experience is required, which is why every new application is clarified by our application technicians by telephone.
The lateral pressure force remains practically unchanged over the entire scope of spindle deflection, no matter whether it is deflected by 5 or 1 mm only.
The engraflexx deburring tools can be used for practically all machined materials.
However, it should be noted that different deburring cutters must be used depending on the material of the workpiece.
Depending on the materials to be processed and the deburring requirements, a wide variety of grindig bits can be used in the tools.
As a standard we use conical router bits with a point angle of 90° with our tools.
Depending on the task, however, routers with a wide variety of contours are also used.
This depends essentially on the desired results.
As a basic rule, with larger milling cutter diameters the abrasion performance (deburring thickness) increases.
Whether a secondary burr arises and how thick it is normally depend on the deburring cutter that is used as well as on the various adjustment parameters.
When processing aluminium as well as various other materials the use of coolant reduces the formation of secondary burrs.
If there is a requirement for absolutely burr-free edges, we offer appropriate tool solutions with an integrated brush, whereby the deburring and smoothing of any secondary burr take place in a single working process.
The milling of precisely defined chamfers is possible, although this requires special milling cutters with an integrated side stop.
Appropriate special milling cutters can be acquired from us ex stores.
The milling of smooth run-out radii is possible, although this requires special milling cutters with an integrated side stop.
Appropriate special milling cutters can be acquired from us ex stores.
It is essential to note that milling bits are always inserted in the tools, in the same way as these are used in hand-held grinders.
Milling bits in standard versions can be used for many applications.
However, this does not always produce the desired result. Depending on the deburring quality required or the respective machining material, it may be expedient to use reworked or specially produced milling bits.

Experience has shown that the wear on the milling bits is almost insignificant.
Even if used in three-shift operation, it is usually only necessary to replace them after a number of weeks.
No, the operation of all deburring tools we produce is completely maintenance-free.
However, it is necessary to ensure that the maximum permissible spindle deflection is not exceeded.
This can have various causes, which can be remedied as follows:
This can usually be rectified with ease by optimising the machine parameters.

The following always applies: in particular with engraflexx EC tool types with lateral deflection, it is not possible to achieve the same visual surface quality as with securely clamped deburring millers.
This is due to the characteristics of the deflecting spindle. However, due to the often very small deburring thickness, these visual quality defects are insignificant in the majority of cases.
If you require higher deburring quality then this is possible with a range of measures.

This phenomenon can arise in particular with the use of engraflexx EC- tool types and can be caused by the following:

This decision depends on a wide range of criteria and is not always simple.
That is why we always have an initial discussion on the telephone with every new interested party. Due to our many years of experience, we are then able to recommend the optimum respective tool type for the customer.
