BACKGROUND OF THE INVENTION The present invention relates to a machining cutter having a base body having milling knives with edges secured to a drive shaft by means of a bushing and which can advantageously be cut with bark for debarking.

- 2 Two types of wood profiles are known to be useful for the machining of όβ wood pellets, which are used to produce uneven bumps in woody stumps and wood chips, eg. branches can be mown in the rain. The thorns can be as expensive as the ones that fall, and the smaller thorns of the smaller ones are preserved. In addition to bson, the formation of snags, the production of grooves in the grooves and the finishing of the wood from the end are also lohozogic.

Cylindrical milling cutters with circular milling knives arranged in their circumference are known in the same way as sand milling cutters; The known solutions have significant drawbacks. If, for example, a woodcutter is cut with a cylindrical milling cutter, the woodcutter can be machined in a narrow band corresponding to the stubble milling cutters. After the rains, the cutter should be lifted with the help of a salt shaker. Ka, on the other hand, for use with a combined cylindrical face milling cutter, which also has milling cutter blades on its face, the feedrate s is also axial. The milling blade must be significantly smaller than the radius of the cylindrical milling cutter because the milling shaft has no or insufficient garden velocity ahhos to ensure that the edges work properly • * · · • · ·

- Become 3 heat. As llyan woodworking with traditional milling cutters •· and time consuming ··. Outside of Ε ·· η, there is a rain company for relatively large drive forces.

In principle, it is possible to have a circular solver, e.g. a fatOrsset is milled in a cavity direction, in which case it is tilted as a function of feed omolkedéoe. To avoid this, the cutter blades should be aligned parallel to the terse axis, despite the inclined position of the cutter. The edges so flattened in the as-so-so-so-so ^M Post-cut are effective, with ani vibration and great pain. In any case, it is not possible for s to use the milling cutters that have been cut down so far to make the tree passes flawlessly. Other types of wood profiles will have neon or even larger nohesgs.

The present invention relates to the development of an improved outboard woodworking mill cutter of the design described in the skylight, which allows one-turn machining of logs and other crosswinds without having to cut the outer contour with ribs or grooves. The invention also relates to increasing the cutting speed and cutting depth, the reduction of the driving force, and the reduction of the germination.

The embodiment of the present invention provides that the milling knives are axially projecting to at least one end of the milling knife body and that the projections have additional edges in addition to the edges disposed on the periphery of the milling cutter and each inner side facing the sleeve. Surprisingly, by modifying the very single molecule as mills for the ion, the disadvantages of the prior art can be overcome to a great extent. Despite placing the naro parallel to the crown, any cylindrical diameter can achieve a cylindrical body where the depth of cut can significantly exceed half the diameter of the naro and everything at an axial feed can be greater than the edge length of every tttras. The present invention provides high performance at a relatively low speed with a milling cutter. The present invention can also be used in other types of machining in addition to machining wood shavings and other circular edges, e.g. slotted, for milling corners, for producing flat surfaces and, finally, for cutting whole wood shavings in a continuous session.

The advantageous properties of the woodworking cutter of the present invention are based essentially on the fact that the milling knives on the cutter face with relatively short frontal lips on the front face of the cutter have narrow curved strips corresponding to the feed of the machined wood olive.

- 5 ▼ branches one after the other and · in the direction of the mard axes they leave a nucleus of matter left behind. After the cutters protrude to the cutter's body, for a long time the cutters have a protruding spike and there is room for this remaining core. But then, on the back side of the mard feed, it is removed on the inside of the mard legs, according to the invention.

In a preferred embodiment of the woodworking mill according to the invention, the projections of the milling knives are formed by spoon-like concave grinders which are delimited by a peripheral edge on the radial outer side, an inner edge on the radial inner side and an anterior face on the axial side. The three edges, meanwhile, are curved along rounded arcs. From this concave design of the Slytherin knives, the nobles have good cutting properties, but the edged knife quickly and unhindered from the cutting process kdrayesetab.

Another advantageous embodiment of the woodworking cutter of the present invention is that the ridges, in particular around their peripheral edges and / or inner edges, are formed radially outwardly in a slightly convex manner with respect to the axis of the cutter. With this solution, you can also improve your cutting properties and avoid the need for razor blades that are noisy but require a lot of power. This design makes it easier to change the direction of the cutter, ie

translate the axis of the far 'sun axis. The protruding arms of the handkerchiefs are slightly oscillating in the radial direction with the axes of the base line of the body, slightly sloping in the rain.

Ahhos, graciously, when the axis of the ridge is set parallel to the axis of the lance, it is possible to obtain a slanting incision, with the lance knives on its base perpendicular to it, but in that case the base body must have a bending angle of at least 10 °. . Thus, even with parallel alignment of the axes of the naro and the moggled fatskin, fatOrss becomes smooth kernal.

Oalssorphins have been shown to have a cutter design with tip lengths exceeding 20 to 50 ares compared to basal body. The ever-present native of the protruding meadow depends on the overall diameter of the cutter, the size of the cutter blades, the intended sow and other hooks, such as the bottom of the wood being worked, its cutting speed, etc.

The circumferential edges and the edges of the radial blades have a radial distance from the radius * of the invention, because the radial distance is the diameter of the base body.

There are 5-10 á-a roasters. To further optimize the cutting behavior, the invention is concerned with the inserts being positioned in front of the circumferential edges, e.g. up to 10 °.

11, the burrs 8 of the knife blades 5 'of the mud 1 on the backside of the naro are cut by an internal cut. Thus, a cutting line 19 is kelotkoskos. The milling cutter 1 thus produces a radial cut surface 20 which is substantially helical in the circumference of the fatOrss 12 and has a height corresponding to the cutting depth of the cutter 1.

After cutting, the cut wood surface becomes a cylindrical surface, with no ribs or grooves, and forms a continuous flow during the incline of the aard as 1 mard. As shown in Figure 5, the axial displacement of the cutter 1 is greater than the native edge of the circumferential edges 7 of the cutter blade cut in the circumferential circumference of the wood blade 12 at each circumference. So every twist of the 12 fatBrss, it has a fairly oscillating strip of it.
