Deburring tools engraflexx

The core element of the engraflexx EC tool type is the radially deflecting tool spindle, which is held in a central position by a pre-tensioned spring mechanism.
When the workpiece contour moves down, the router bit that is used therefore always automatically positions itself at the workpiece edge that is to be effectively deburred – even if this differs somewhat from the programming.

This means that each workpiece is automatically provided with even deburring independently of any dimensional or position deviations.

This special design with lateral deflection is used for fine deburring and reworking tasks on a wide range of workpieces. Processing tools suitable for use here include radial brushes, grinding bits and other grinding and polishing tools.
Mass and position differences in the processing surface are automatically compensated for by the deflecting spindle. The deflection force of the spindle can also be steplessly adjusted, so that work can always take place at the optimum pressure.

Upshot: using the engraflexx EC-E it is possible to take on previously unimagined deburring and rework tasks – with the greatest possible process reliability and automatic wear compensation of the processing tools.

Range of application

Defined, fine deburring and rework of arbitrary workpiece contours
with radial brushes, grinding or polishing tools.

Function of the stop system
Due to the special geometry of the stop nose and the smooth-running bearing, the stop automatically rotates around the spindle axis so that the stop tip is always directed against the edge to be machined.
This allows workpieces with various internal and external contours to be reworked or deburred with absolute process reliability.

The engraflexx LC-U/BA tool type is based on the engraflexx LC-U, which is also equipped with a spring-mounted, ring-shaped brush attachment.
The tool was designed for deburring workpieces where there is a demand for absolute deburring freedom, i.e. where no secondary deburring whatsoever is permitted.

Dimensional and position differences are compensated for by the spring-mounted spindle in accordance with the deburring process with the engraflexx LC-U, i.e. the actual deburring is carried out by the router bit clamped in the tool. Any secondary burring that occurs is eliminated again in the same work step by the ring brush.

The lateral workpiece stop attachment can be used in conjunction with the tool types engraflexx AP, ESP, and SX.
Due to the special geometry of the stop nose and the smooth-running bearing, the stop automatically rotates around the spindle axis so that the stop tip is always directed against the edge to be deburred. This means that workpieces with a wide variety of internal and external contours can be reliably reworked or deburred.

The lateral workpiece stop attachment is used if dimensionally tolerated chamfers or seamless radii have to be milled on workpieces.

Special feature of the stop system:
the router bit positions itself directly onto the workpiece edge during “conventional” use of the deflecting spindles. Accordingly, the thickness of the burr can have an influence on the dimensions of the deburring, i.e. with different burr formation thicknesses, the deburring can also have some differences.

If the deflecting spindle with workpiece stop attachment is used, this supports itself at the side on the edge of the workpiece. The main benefit: the milling cutter clamped in the spindle is always held at the same defined distance from the spindle regardless of the position difference or burr thickness.
Therefore, neither the burr thickness, feed speed or the lateral pre-tensioning force has an influence on the dimensions of the edge machining.

Application area

Precisely defined reworking of workpiece edges
with deviating positions or dimensional differences, e.g.

• Milling off of protruding burrs

Solid carbide conical router bits are used for most deburring tasks.
Depending on the respective requirements (desired size and quality of the deburring, workpiece contour to be deburred, etc.), these are standard products or reworked or specially manufactured router bits.

On the side you can see a selection of the conical router bits offered by us, all of which are available from stock.

Conical router bits with extended shank are used for deburring contours whose accessibility is restricted due to interfering edges etc.
The deburring of recessed workpiece edges is also a classic application of these router bit versions.

On the side you can see a selection of the conical router bits we offer with an extended shank.
A certain standard range is available from stock. Special router bits with shanks of any length can also be manufactured, taking into consideration the respective delivery time.

The use of special router bits is required for deburring rear-side edges.
For this application we essentially offer two versions of router bits:

• Version with simple reverse cutting toothing (for deburring of rear-lying edges)
• Version with double-sided toothing (for deburring front and rear-lying edges)

On the side you can see a selection of the special conical router bits we offer, of which a standard range is available from stock. For special applications, the router bits can also be manufactured in various sizes and designs to customer specifications.

Depending on the respective application, router bits with different shapes are required. In addition, we offer a wide range in various sizes and shapes.
The selection of the router bit always depends on the task at hand. If this cannot be solved with a standard product, special router bits can also be produced to customer specifications in any shape.

 On the side you can see a selection of the router bits we offer, most of which are available from stock.

Router bits in cylindrical form are often used for milling off protruding residual material.
A typical application is e.g. the milling off of protruding parting lines on castings etc.

The router bits are available in different sizes and toothings as standard. For special applications, the cylindrical router bits can also be manufactured in any dimensions.

In principle, a distinction is made between two types of cylindrical router bits:

• Standard version with gear teeth on the circumference (for use in tool types with laterally deflectable spindles)
• Version with additional spur toothing (for use in tool types with axially spring-loaded spindles)

On the side you can see a selection of the router bits we offer, most of which are available from stock.

Milling cutters with integrated workpiece stop are used in conjunction with the tool types engraflexx EC- or ESP- and SX with a laterally deflectable spindle.

The main area of application is the deburring or reworking of workpieces, where there are increased demands, such as:

• Precise milling of protruding material residues or burrs without damaging the actual workpiece contour
• Milling of minimal, often narrowly tolerated chamfers
• Milling of larger, dimensionally accurate chamfers
• Milling of seamless radii

Depending on the requirements, the milling cutters are fitted with ball bearings or rotating stop pins as stop elements.

On the side you can see a selection of the stop milling cutters offered by us and available from stock.

For certain applications, grinding bits or special grinding elements are used in conjunction with the deflectable tools.

Especially in robot applications, the deflectable tools manufactured by us are often equipped with an automatic tool changing system.
As actual grinding bits or grinding elements, the most diverse tools available on the market or specially manufactured tools are used.

As a user, you do not need to worry about the selection in this respect either, as we offer our customers the complete tool solution for each new application: this consists of the deflectable deburring tool and the actual machining tool such as a router or grinding bit, etc.
