High machining data demand high process reliability. These primary demands on a reamer in the modern production process regularly present many users with great problems, because only tool solutions that meet these demands offer the preconditions for an inexpensive product that can be produced in high quantities and with a consistently high quality.
In the field of fixed reamers, a design was therefore integrated which allows enormous machining speeds and at the same time close tolerances and the highest surface qualities in the sense of high-performance cutting. The tool concept of the HPC version is characterised by its wide range of application possibilities. At the same time, machining qualities are achieved comparable with those produced by grinding or honing.

An important expansion to this range of HPC Cermet reamers is the expandable variant. It combines the advantages of the solid tool with those of adjustability. The adjustment mechanism can easily absorb the enormous loads of HPC machining. By contrast with the solid variant, the tools are fitted with soldered Cermet blades. The adjustment range is approx. 0.03 mm above the nominal diameter. The main fields of application of the expandable variant are the compensation of wear-related reductions in diameter and the allowance for material-specific and clamping-related influences on the machining diameter.

MR REAMERS :

With the newly developed high-performance reamers from the MR series 01, 02 and 03, BECK is providing the first standardised system for multi-bladed reamers. The reduced number of variants in these series covers a large number of possible applications in fine machining with significant rationalisation effects.
The MR reamers in this programme are available as fixed, expandable or finely adjustable variants that have interchangeable primary dimensions and in this way cover a wide spectrum of applications. As straight or left-hand fluted versions they are suitable for through bores or blind bores and can be designed with suitable cutting materials, coatings and cutting leads to suit the material of the part.

Advantages :

Due to the compatibility between the series, it is possible to straightforwardly change to the optimum system reamer for the specific case if general conditions change in production,for example different quantities or bore tolerances. In this way the flexibility of the MR system guarantees the most cost-effective solution.

RR01 REAMERS:

In order to meet these demands, Beck has developed the RR 01 product family.The extensive range available from stock offers through bore and blind bore variants as well as an expandable version for through bores to quickly meet customers' needs.

Advantages :

The main field of application of our RR 01 reamers lies in the machining of steel and cast iron (GGG50). The outstanding feature of this product range is the optimum guidance of the cooling lubricant to prevent thermal shock at the start of material cutting. The extremely unequal spacing in relation to the geometry is also a major determining factor for the good machining results of this product range, and due to the fact that the standard sizes in the diameter range from 4-40 mm are available from stock, our RR 01 reamers can be delivered without long waiting times. From the economic point of view, too, the RR 01 Series is an interesting variant to tools previously used, as the RR 01 can be conditioned by our regrinding service and is then inexpensively ready for use again.

VR01 REAMERS:

A crucial criterion for the performance of multi-bladed reamers is the number of blades. A design limit on the number of blades is defined by both the diameter of the reamer and the space required for blades and chip spaces.The VR01 multi-tooth reamers push back the existing limits by eliminating the chip spaces and creating room for more blades. At the same time effective coolant supply directly to the blades is still ensured.
The coolant is supplied via a streamlined duct that is formed at the periphery between the blades and the wall of the bore and therefore also ensures cooling and lubrication of the blades for high speed machining.

Advantages :

The blades on the reamer body can be easily replaced and reconditioned several times. At the same time, the additional blades on the VR 01 create several other positive effects for machining. The machining time is drastically reduced,the tool lives are increased and the bore quality, in particular the circularity of the bore, is improved. The shape of the tool, which is defined by the design, ensures the chip is intentionally discharged forward. In addition, the coolant also ensures reliable chip transport forward.The chips therefore do not come into contact with the part of the bore already reamed.
The strengths of the VR 01 multi-tooth reamer include the machining of steel and castings. Reaming using the multi-tooth reamer is so effective that, for instance, honing during fine machining of bores for hydraulic components is often no longer required.

HNC REAMERS:

This series particularly suitable for high-performance machining impresses with its high performance,the high cutting data that can be achieved and the resulting high productivity.An outstanding feature is the special design which allows a selective coolant supply directly to the blade.The production from solid carbide with various high-strength coatings makes this tool series an interesting solution for the machining of a wide range of materials..

Advantages :

In its preferred field of application of steel machining, the HNC reamer is a real "work wonder".But in the machining of aluminium, CFRP, GFRP, stainless steel or for hard machining,The HNC reamers with their specially developed blade geometry provide outstanding work results.Furthermore, our HNC reamers in the diameter range between 3 and 20 mm are a particularly cost-effective alternative to other methods of machining. The HNC reamers are designed with extremely unequal spacing in their geometry and are available in many fitting diameters from stock.

In order to counter the rising tool costs, BECK has developed a modular tool system that offers a high degree of flexibility as the tool holders can be fitted with different reaming heads via defined interfaces.
The advantage here lies in the fact that only one holder adapted to the machine interface is required for different machining operation and the optimum reaming heads can be selected with respect to cutting material, coating and blade geometry to suit the material to be machined. Short tool change times, generally without remeasuring, make this type of tool attractive for medium and large lot sizes as the change can be carried out directly at the machine.
The basic holders are so stable and designed with µ-precision so that the additional interface compared with monoblock tools presents no limitations. A further positive aspect for replaceable head tools is the high savings potential with respect to the material costs, particularly with large diameter.

XR REPLACEABLE HEAD REAMERS

Precision and stability are crucial for a modern, high-performance replaceable head system for reaming.The new XR replaceable head reamers from BECK satisfy all these demands to the letter.The connection is designed such that the best possible stability and rigidity are achieved by a taper and a face connection. The special design and manufacture of the thread and taper-face section guarantee the highly precise radial run-out accuracy .

Advantages :

Thanks to the simple and safe handling, the reaming heads can be replaced in the machine tool quickly and easily. That saves setup costs. The range of XR replaceable head reamers covers three different series of replaceable heads in the diameter range from 8 to 40 mm for through holes and blind holes.
The most important elements of the new connection are the taper and plane face.The exact interplay of these elements ensures maximum stability and rigidity. Taper and plane face are complemented by a threaded journal directly adjoining the taper and connected to the taper in one piece. These three characteristics coordinated perfectly with one another ensure the highest changeover accuracy, high clamping force and very simple handling at the new connection.
Modern production facilities allow plane face and taper to be manufactured with the highest accuracy, and hence to reliably achieve a radial run-out of ≤ 5 µm. The high stability of the system results from the pretension of the taper. When tightening completely, the taper expands slightly in the holder and the plane face has a perfect contact.

XR HOLDERS

The advantage of the XR replaceable head system derives to a great extent from the fact that only a small number of holders have to be kept is stock, for example different lengths, leading to a significant cost saving. The heads can be selected with respect to cutting material, coating and blade geometry to suit the material to be machined. The exact interplay of plane face and taper supplemented by a threaded journal creates a high-precision interface with maximum stability and rigidity.
