Transverse rupture strength shows the strength of “three points bending” .The weight of “P” can be counted according to the upward formula,when the rectangular test piece was fractured.

*2　Test of Tensile Strength and Compressive Strength

P

Tensile test test and Compressive test are difficult. Because it is difficult to fix a tensile specimen.And Compressive test is dangerous.

Specimen

Adpter of specimen made by fujilloy.

*2=Broken load ／ cross section

The fracture toughness is often used to measure the easiness of crack expansion after it happens. The bigger the numerical value,the more difficult crack expands.

Hardness of cemented carbide varies by WC grain size and Co content.The grain size finer and Co content lower, alloy shows harder feature. ultra fine grained cemented carbide show less defect and rather higher figure of TRS because almost of them cemented carbides passed through HIP treatment.

Thecnial Data

Definition of Cemented CarbideCemented carbide is a general term for 9 sorts (W, Mo, Cr, Ti, Zr, Hf, V, Nb and Ta) of

carbides combined with Fe Group (Fe, Co, and Ni), and the most popular one is

WC-Co series alloy.

WC grain

Co phase

Charcteristic Comparison of Tool Material VarietyTable.1 shows properties of various tool materials.

Cemented carbide of Fujilloy possesses, in particular, highest value for Young’ s modulus of elasticity

and thermal conductvity compared with SKD, SKH and ceramics.

Cemented carbide Fujilloy shows the hardness wide range.

This 2 factors mean that Fujilloy have the various grade coreesponding to various uses.

Superiority of Cemented Carbide1. Improve the detailed and precise level of tool dimensions.

2. Improve the surface conditions of tools and it affects good outlook of the products.

3. Improve wear-resistance of tools and wear-dust mingled into the products.

4. Improve machinery operation ratio and minmize frequency maintenance through prolong tool life.

5. Above all superiorities contribute the enviroment.

The hardest grade among fujilloy cemented carbide, such as ultra fine grained requires severe grinding condition control.Resin bonded diamond wheel with cocentration ratio 75-90 (3.3-3.96 ct/cc) is suitable for cemented carbide which hardness is over than 90HRA. Table 1 shows typical case of grinding conditions used fujilloy FAW-IC resin bonded diamond wheel. Careful treatment to rough grinding work is required for fine grained type and the hardest type because they are easy to get chipping.At the finishing work, those types of material appear another trend. Photo 1 & 2 show the ground face and edge of a test piece treated in accordance with the finishing grinding condition mentioned in Table 1. Each photo appears WC grain size and Co content ratio efficiency.These photos appeal that grain size become finer, surface roughness and chip defect on edges become smaller.And effected by the certain level of Co content prevent surface roughness and chip defect of edges.Those phenomena are recognized as related to fracture toughness and tensile strength.It means that ultra fine grained cemented carbide with high tensile strength, and which alloy was ground as finishing condition, is suite for the blanking punch tools to which sharp edges are required.

EDM TechniqueIt is necessary to minimize microscopic cracks mentioned as bellows. 1) Lower electric current value, and control fabrication speed slower 50% than standard method. 2) Use diameter less than 0.2 wire electrodes and restrain fabrication power. Above condition showed in Table 2.Fig.1 shows TRS (transverse rupture strength) comparison data in related with grain size and Co content when material is fabricated by grinding method and 3 types of wire cut electric discharge machining (W-EDM) method in Table 3. fujilloy cemented carbide property; in case of grinding method, WC grain sizes become finer TRS become bigger. Incase of W-EDM method, WC grain sizes become finer TRS become smaller in any type of 3 methods. Particularly WC grain size 0.5μm range, it shows obvious lower figures of TRS. Finer grain alloy is easier to get fine cracks pointed by arrow in Photo 3(a). Bigger grain alloy also get them but limited to degenerate stratum showed by arrow in Photo.3(b). Above should be considered for selection of tools strength.TRS shall be recovered to original value by taken off degenerate stratum, which was caused by electric discharge machining, through grinding process.

It is also required to take care of corrosion in electric discharge machining process. Fujilloy prepares appropriate material for it as V series, such as VF12, VD45, TVG60 and others. V series material shows less cracks and corrosion compared with other type material which hardness is similar to V series.
