New qualities and higher performance in the drilling and milling

For this reason, the company has expanded the range of diameters of its Xtra·tec Point Drill bits to has developed a new generation of drill bits made of solid carbide or offers to a greater depth of drilling drill bits XD, among other new features.

Since its release, there have been numerous contributions to the range of Xtra·tec Point Drill bits with interchangeable tip. Walter complies with the requirements of many customers in diameters and depths of holes. And now this development goes one step further: the upper limit for the diameter of the hole reaches the 38 mm.

Xtra·TEC Point Drills are bits of first quality offered to the market an optimum result in performance and quality of hole. This is mainly due to the interchangeable tips of fine grinding have been manufactured using materials for cutting tools Tiger·tec, the seats of Prism of high precision in the body of the drill bit and a solid fit. In the range of diameters up to 24 mm, the variant 10xD (designation of type B4010) now reaches depths within the range of depth of the hole. Variants for depths of hole of 3xD, 5xD and 7xD (B4013 and B4015 B4017 type designations) were already available for hole diameters up to 32 mm. Is there where act these contributions that many users of the fields of mechanical engineering and machinery, as well as many related industries were waiting for: the diameter of 38 mm hole is now the new upper limit for depths up to 7xD. The range between 32 and 38 mm is covered by a large number of important intermediate sizes. For this range of expanded diameter, Walter will initially provide an interchangeable tip type 6003 for grades of stainless steel, material with unfavorable Court properties and structural steels which produce many chips.

Walter is replacing the previous Alpha 4 series by a high-performance drills manufactured in solid carbide included in the range of product X·treme. The name X·treme is due to its advanced features. Associated factors include a broader scope, a significant increase in performance and more reliable process. The most striking feature of the new high performance bits made of solid carbide Walter Titex X·treme are their four edges; the previous generation had only two. Enhanced orientation increases the reliability of the process, not only in drilling situations that are not critical. In particular, the tools maintained your address in the entry or exit of the drill, even when machining is performed on sloped surfaces. This increase enlarges the area of application. In many cases, it reduces the operation time for the components, the user is able to give up operations of preparation such as milling of a flat surface or the drilling of holes Guide. The four edges are also used to ensure a better surface of the hole. Another new feature is the lining XPL chrome-clad aluminum nitride-based. This coating is currently the highest level of development for solid carbide drills. It enables the universal use of the tools for all the groups of materials ISO.

Walter is expanding setting options for the system of milling modular ConeFit introducing new monobloc tool. Maximum stability, the performance of the strawberry is even closer to the limit. With these new monobloc tool, Walter now offers an option with the minimum possible unions to the users of the system of milling modular ConeFit. The tool with a special ConeFit thread conform directly to the spindle of the machine, which means that the usual cutting between the handle of the modular tool and the sleeve area is not necessary for tightening. In 2xD, length of fixation of the strawberry is extremely short. Therefore, setting/tool system maintains an excellent level of stability. During machining, extremely high cutting data can be and the performance of the tool can be used in its entirety.

In order to reach the maximum possible number of users, the monobloc tool come in several versions to accommodate the most common tool spindles of the market. HSK 63A, SK40 and MAS BT40 interfaces are included in the field of machining/milling centers, and in the field of the lathes with driven tools, adapters Walter Capto C5 and C6.

Depth record without returning to the surface: drill bits XD reach a depth of drilling 70xD

XD Alpha 4 of Mark Walter Titex drill bits are capable of drilling "extreme depths" without points. This is particularly timely because it is the first time that a tool of this type reaches a surface of 70xD drilling. Deep holes in an operation: here the XD bit of Walter Titex brand are unbeatable. Something true now more than ever, because they have reached a depth of 70xD. So far the standard depths had been 30xD; reached up to 45xD in special cases. If earlier we were talking about a slow and gradual approach towards greater depths, we now speak of jump. The factors responsible for this large increase in performance are fundamentally three special features structural and manufacturing: Walter is producing solid carbide entrerroscas using a new method that enables this type of solid carbide drills. The finishing procedure also requires a special grinding processes. As with all the XD bit, the cooling is done via internal cooling channels. While the depth of drilling is great, no unity cooling special as, for example, an external high pressure system is not needed. It is enough with a standard cooling unit such as that available in any machining center. "On the one hand the Alpha4 XD70 is based on the technology exhibited by their smaller sisters, on the other hand, its specific details make it a completely new tool," explains Helmut Gschrey, Walter product manager.

Two years after the release of the high-performance cutting tool made of material Tiger·tec Silver, Walter has completed its range of inserts indexable with the full range of strawberries that are used for the machining of steel and pig iron. In many cases, the increases made in the performance by Tiger Silver teeth are up 100%. In this case, for example, for the milling of the faces of the sliding guides made of ST52-2 using a strawberry octógona Xtra·tec F4080. The user has confirmed that the useful life of the tool has doubled. Tiger·TEC Silver has replaced the material for cutting tools so far was the reference point.

As announced the specialist in carbides based Tübingen, the indexable inserts Tiger·tec Silver are already designed for drilling and turning. Developers are currently working to extend the degrees of cutting material. The degree of current universal inclusion WKP35S is being reinforced with degrees whose level of resistance is higher, even with higher levels of hardness.

Package of geometries for tronzado operations

On the other hand, Walter will recommend the trio of Nf6, nf5 and SG4 geometries for tronzado applications. Nf6 and SG4 geometries have been available for about 2 years in the Walter Cut range. Nf6 provides a very sharp edge that is designed in a positive way to low forward speeds and SG4 has been cut to provide maximum stability at high forward speeds. Nf5 geometry is a recent development for the range of progress. This rompevirutas covers the gap between the two previous geometries. Approximately 60% of all tronzado applications can be covered with the nf5. The whole system locked Walter Cut includes stable monobloc tool for inserts of slotted double-edged classified G1011 and XLDE. The XLDE for size GX16 (16 mm in length) cutting inserts is ideal to produce small parts. It has been designed especially for use in machines with linear units. Other tool systems include deep cut with four points autofijación disposable blades, classified under G1042, and multifunctional blades hardened with fixing through screw and classified under G1041.

The multi-functional tools are in fashion, especially when it comes to the production of thread. Walter is, therefore, optimizing its range of tools consistently in this direction through innovations or updates. The most recent update of solid carbide with countersunk threaded Strawberry manufactured by specialized brand concerns Walter prototypes for the range of threads of M3 to M16. In a field test with stainless steel 1.4301, this new variant of threaded solid carbide BUR managed to double the lifespan of the tool compared to the previous generation tools. The test was carried out using a threaded Strawberry in size M8. This progress is based on several new details: a substrate of carbide grain extremely fine and improved that guarantees a high resistance to wear. The Helix angle has increased to 27 degrees (previously 10 degrees), something which is good for the soft cut. With the loss of fewer metal thread, avoiding that chip will enter and damage the adapter. This also allows a shorter fixing system which results in greater stability. Together, all these characteristics lead to a greater operational smoothness, and therefore a minor wear tools, two conditions to ensure a long service life of the tool. The excellent quality of threads is a welcome side effect. The maximum cutting speed is 90 m/min, a still possible value with the hardened steel 42CrMo4, for example.

The countersunk that occurs before the milling of the threads is of 90 degrees with the new version (formerly of 60 degrees). This value has been put into practice and guarantee a start of thread almost without Burr.

The F4338 Xtra·tec is a new Member of the family of Strawberry Hedgehog of Walter and his Constitution is extremely strong. Due to its special design details, this tool offers the maximum reliability of process, especially in the machining of high-strength with large volumes of court. It is clear, the F4338 Xtra·tec with a diameter that varies between 63 and 125 mm moves towards the end of the market: the machining of high resistance. A print that is also underlined with great seats for inserts indexable type AD.T 1807 which can be completely sintered in circumference or connected to Earth in circumference. Therefore, this new Member is who has longer "spikes" of the family of Strawberry Hedgehog Xtra·tec.

Thanks to the smooth cut, or the edges placed helicoidalmente or the depths of sinking up to 95 mm are problem escuadrar with Strawberry and the cut. Even with lower performance machines, are available for cutting speeds higher than the average with this tool thanks to the characteristics Xtra·tec. Equipped with cutting Tiger·tec Silver material, this strawberry is suitable for all types of pig iron and steel, and with the inserts materials coated PVD-Alox, even for difficult-to-cut materials and stainless steel. Along with general engineering, their typical applications are mainly in the energy sector and in the aerospace industry.

In addition to the inserts extremely strong for large capacities of cut, the tool has a special and compelling design feature. The first row insert indexable is supported by an additional axial fixed stop.
