Definitions
- the invention relates to carbide tools that are suitable for drilling or milling processing of materials.
- tool geometries which are characterized in that the tool consisting of hard metal has a longitudinal axis, which is the axis of rotation in the machining of materials at the same time, and a perpendicular thereto cross section, which is surrounded by a circle.
- the diameter d of the tool (corresponds to the diameter of the enveloping circle) is smaller by the ratio l / d than the length of the tool, where l is the length of the axis of rotation.
- Chips are generated by the cutting edge at the end of the tool, which, as soon as the borehole has reached a certain depth, are conveyed out via one or more helical or rectilinear grooves located in the cylinder surface of the tool.
- the ratio l / d can be between 5 and 20, but reaches in the case of miniature drills for the processing of printed circuit boards for the electronics industry quite a factor of 200.
- the tool is also designed so that not only at the end, but also effective laterally in the cylinder surface cutting grooves, the chips promoting groove can be omitted in whole or in part.
- Can transmit torque which is composed of the cutting forces and the conveying forces of the chips in the groove. Falis jam chips, stress peaks occur.
- the groove (s) represent a reduction in the loadable cross-sectional area and are potential starting points for catastrophic crack growth that results in tool breakage. Due to the continuing trend towards miniaturization, a reduction in the diameter of the tool results in a quadratic decrease in the transmittable torque, while the cutting forces only fall linearly. Processing safety decreases due to increasingly probable tool breakage. In particular, tools for drilling and milling printed circuit boards for the electronics industry as well as deep hole drills are affected.
- the maximum forces to be transmitted of the tool depend on the material properties of the hard metal material, and can be determined by commonly known mechanical characteristics such as bending strength, or crack toughness (Kic).
- the fracture toughness in the hard metal industry is usually calculated from the crack lengths of the Vickers hardness impression, the hardness and the stress according to the Shetty formula. While the flexural strength describes a real body containing fracture-inducing defects, the Kic value characterizes the fracture toughness of the material itself and thus the strength potential of a material with complete freedom from defects, and is therefore more suitable for systematic comparisons of materials regardless of the quality of the structure.
- the wear resistance of a tool correlates positively with the hardness. However, hardness and strength can only be improved at the expense of the other property. Desirable for the tools described, therefore, would be an increase, for example, the strength without loss of hardness, or an increase in hardness without FesttechniksverSust.
- Hard metals that is composites of metals of the iron group as a binder on the one hand (“binder phase”) and hard materials (carbides, nitrides, "hard material phase”) on the other hand, have as materials for processing
- binder phase composites of metals of the iron group as a binder
- hard materials carbides, nitrides, "hard material phase”
- the metallic binder used is predominantly cobalt. As a result of the sintering process, this also contains, in addition to W, C, also fractions of Cr, for example, if chromium carbide is used as the hard material.
- the metaltic binder may also contain Fe and Ni.
- EP 1 007 751 A1 describes that by using Fe-, Co- and Ni-containing binders, a hard metal with better plasticity is obtained, which is attributed to a purely austenitic binder phase after sintering.
- WO 99/10550 describes tools for boring and milling machining with austenitic binder phase, wherein the metallic binder contains 40-90% by weight of Co, and in each case 4 to 36% by weight of Ni or Fe, Fe and Ni being in the ratio 1.5 to 1 to 1: 1.5 stand. It is known that by varying the ratio Fe: Co: Ni in the metallic binder phase of hard metals, the phase inventory can be varied very widely.
- WO 99/10550 shows the advantages of a stable austenitic lattice state of a FeCoNi binder alloy after sintering.
- the binder alloy contains between 90 and 60% by weight of Co, the remainder being 100% by weight of Fe and Nt, the Fe to Ni ratio being about 1 +/- 0.5.
- Such purely austenitic binder phases due to their stable lattice type, offer advantages at all temperatures up to the melting point.
- Object of the present invention is to increase the strength of milling and drilling tools made of carbide and thus their strength, so the process reliability is increased. At the same time, the hardness should remain comparable.
- This object is achieved by a milling and drilling tool with an optional two-phase (austenitic / martensitic) binder phase, which satisfies the conditions Fe 50 to 90 wt .-%, and Co: Ni less than 1.
- the metallic binder phase can advantageously contain further alloy additions such as Cr in order to increase the hot hardness.
- the tool can therefore be shaded, ie that only the actual tool is made of carbide, and the transition to the machine tool from another material, such as steel! The transition can be accomplished by a joining process such as shrinking, or by soldering.
- the invention therefore relates to a hardmetal tool rotating about its own longitudinal axis with a! / D ratio (ratio of length to diameter) of 2 to 200 for the exciting machining of materials, comprising an at least two-phase austenitic / martensitic binder phase and a hard material.
- the invention relates to a rotating around its own longitudinal axis carbide tool with a l / d ratio (ratio of length to diameter) of 2 to 200 for exciting machining of materials containing a binder phase and a hard material, wherein the binder phase of a Hard metal binder phase with the Hauptbinderberetemaschine iron, nickel and cobalt is and the iron content between 50 and 90 wt .-%, the nickel content between 10 and 30 wt -% and the maximum cobalt content is 30 wt .-%.
- the cobalt content is thus 0 to 30 wt .-% or 5 to 30 wt .-%.
- the contents of the binder components of Fe are advantageously from 70% by weight to 90% by weight, in particular from 75% by weight to 85% by weight or from 70% by weight to 80% by weight, Ni 10 Wt .-% to 20 wt .-%, in particular 15 wt .-% to 20 wt .-% or 18 wt .-% to 20 wt .-% and optionally cobalt in amounts of 4 to 15 wt .-%, or from 5 to 12% by weight.
- the Co: Ni ratio is preferably less than or equal to 1, more preferably from 0.5 to zero, wherein the ratio refers to the amount of these metals in the binder, indicated in weight percent (wt .-%).
- binder compositions are particularly advantageous if the ratio Co: Ni is less than or equal to 1 or 0 to 0.5.
- Particularly preferred individual binder compositions are, for example, FeNi 85/15, 82/18 and 80/20, FeCoNi 70/12/18, FeCoNi 80/5/15, 70/10/20, 65/20/15 and 75 / 20.5.
- the contents of the binder components are given in weight percent, based on the composition of the binder.
- the above-mentioned ratio of cobalt to nickel of less than or equal to 1 or less than 0.5 refers to the amounts of these metals one weight percent.
- the binder has no other ingredients than those listed above, except for unavoidable impurities.
