Walter Xtra•tec, dish of high advance F4030 and dish with plate heptagonal F4045

In the industry of the automotive sector, the tendency of greater performance with lower displacements and lower consumption brings achieve a greater mechanical load on the block engine. This requires materials of high quality done of grey foundries (GG) and foundries of compact graphite (GGV). The compenetración of the plates Tiger•tec Silver and of the system of bodies of milling Xtra•tec form an almost perfect union for the mechanised economic and efficient of this type of materials.

The maximum dimensional accuracy, the best superficial finishing possible and increase the productivity until in 100%, can reach today using a combination between dishes to mill, broaches of high performance and tools of threaded of our marks Walter, Walter Titex and Walter Prototyp. This also is the way to reach a cost by piece in the productions in series of complex pieces.

The dish heptagonal Walter Xtra•tec F4045 is of fundamental importance in this sense. Instrumented with the powerful plates Tiger•tec Silver of 14 edges of cut, is perfectly adapted for the planned in desbaste of the camera of combustion. The standard rank includes two sizes of plates and dishes with rank of diameters from 63 to 200 mm. The niquelado in hard provides protection in front of the corrosion, the wear and favours the evacuation of shaving.

The F4045 Xtra•tec can supply in two different steps. The narrow step allow to be used with the maximum productivity in lines transfer with voladizos small. The half step is adapted for machines feebler or conditions of tie up different in a big fan of machining centres. In conditions of stability limited, this variant with the half step, offers us the conditions of cutting higher possible.

The stable plates and heptagonales of the F4045 Xtra•tec offer a total of 14 edges of cut because of being negative plates, this reduces us the cost of the tool and increases us the stability of the process. The positive geometry of the edges of cut gives place to a soft cut. The deep faces of support of the plates guarantee us a perfect evacuation of the shaving, this allows us a high capacity of mechanised (high Qmax) even in machines of low technology.

The system of fixation by coins holds with hygiene the plates in his accommodations. Three rompevirutas —stable, universal and soft cutting— allow to adapt to the different applications. Besides, this system of tie up by coin, positions he only with some fly of the grub screw, with what the plate has very easy access. These properties of the tool guarantee a stable process during the mechanised.

Some conditions of cutting and a life of upper tool to the average are guaranteeed by the rank of coatings Tiger•rtec. The F4045 Xtra•tec can instrument for example with the coatings of high performance Tiger•rtec Silver WKP25S and WKP35S or with the coating PVD Tiger•tec WKK25 for conditions of cutting especially difficult. Designed for depths of past of four to six millimetres, the F4045 Xtra•tec is particularly good for mechanised of piece of grey foundries, for example, motors, transmissions, boxes of crankshafts and carcasas of bomb. The useful life of the tool is sometimes until 75% elder to the available tools in the market.

Another member of the family Xtra•tec of milling is the dish of high performance Walter Xtra•tec F4030 with plates of six edges of cut, which is a dish of high advance. The distinctive characteristics of escuadrado, plunge and copied of the Xtra•tec F4030 are that his plates trigonas are done of a material of cut characterised by his high performance, the Tiger•tec Silver, with degrees WKP35S and WKP35S. His plates of double expensive with negative geometry are extremely stable and guarantee the greater conditions of cutting and life of tool, by the combination of the properties of a soft cut with a greater stability.

On the other hand, an angle of attack of 20º gives us a positive geometry and guarantees us the typical characteristics of the family Xtra•tec, like the soft cut and the little request of power. In combination with the stable design of the body, the tendency to the vibration is reduced to the minimum. This improves the reliability of the process of the tool, even when have big voladizos. Six edges of cut by plate with negative basic form keep us the cost of the low process. This innovative tool is available in a very extensive rank, from 25 to 100 mm. The positioning of the negative plates with angle of attack of 0º to 21º allows us advances by tooth until 3,5 mm and depths of past from 1 to 2 mm.

By his special properties, the F4030 Xtra•tec is particularly very adapted for the mechanised of steel, stainless, foundries and difficult materials when you plan to high advance, entrances in rampa, circular interpolations and plunge. This dish to mill can be used universally in almost all the sectors.

Is precisely with pieces of mechanised that the F4030 Xtra•tec guarantees us a high tax of volume of start of shaving with past drops and high advances. At the same time, a high stability of process is reached by the low tendency to the vibration, even with big voladizos, and the use of stable plates reduce the time of mechanised. For example, When the application is the milling of a cashier, the time of mechanised reduces around 18% if it uses the universal plate P23696 (for mechanised from half conditions to desfavorables) beside the degree WSP45, which does that it was not an insignificant economic profit or, what results an appreciable economic profit.
