The Use of PM Ferritic Matrix for the Processing of Diamond Cutting Tools

This work deals with the use of Fe-Cu alloys for use as matrix for diamonds in cutting tools. In this case it was processed diamond beads for diamond wires - used in the slabbing of dimension stones. Normally, diamond beads are PM processed. The beads of the present work were manufactured using Fe-Cu alloy with addition of 1wt% of SiC as the matrix metallic bond. It was carried out shrinkage/swelling and microstructural analyses, Brinell hardness measurements, as well as the abrasion resistance of beads produced here in confront with commercial ones. The results indicate that it was processed beads with similar abrasion resistance and performance than those of the commercial diamond beads.

The Matrix

The performances of metal-bond of diamond cutting tools were investigated by changing the cobalt and bronze ratio conversely as the matrix material. Diamond tools were fabricated by cold pressing and sintering under pressure at the temperature up to 750 °C. Investigation of the microhardness behavior of the segments was showed that increasing the cobalt ratio causes the increase of the hardness of the matrix material. This caused to decrease of the wear rate of the matrix. Because the matrix wears more slowly than the diamonds, the space between the cutting edges and the matrix is constantly reduced. The swarf cannot be carried away properly, and the segment will continuously lose its ability to cut with higher cobalt contents.

And Performance

Diamond tools suitable for machining operations of natural stones can be divided into two groups: cutting tools, including blades, the circular blades and the wires, and the surface machining ones, involving mills and grinders, that can be of different shapes. For the stone sawing process, the most adopted tool type is the diamond mill, whose duration and performance are influenced by various elements such as: the mineralogical characteristics of the material to be machined; the working conditions such as the depth of cut, the feed rate and the spindle speed; the production process of the diamond segment and the characteristics of both the matrix and the diamond, such as the size, the type and the concentration of the diamonds and the metal bond formulation hardness. This work allows to indirectly assess the wear of sintered diamond tools by signal analysis (in time and frequency domain) of the cutting force components acquired in the process. The results obtained represent a fundamental step for the development of a sensory supervision system capable of assessing the tool wear and hence to modify the process parameters in process, in order to optimize cutting performance and tool life.
