Si3nN4-BASED CERAMIC LESS IN HEAT RELEASING PROPERTY, AND TIP EXCHANGE TYPE CUTTING TIP, END MILL AND ANTIFRICTION TOOL USING THE SAME |
摘要 |
PROBLEM TO BE SOLVED: To provide SiNceramic less in heat releasing property and excellent in abrasion resistance at high temperature, a tip exchange type cutting tip and an end mill containing the same and a roll for plastic processing.SOLUTION: In a SiNceramic, WOof 1 mass% to 7.9 mass% is blended with a raw material powder, set in a carbon case and filled in a vacuum sintering furnace using a carbon heater and sintered under nitrogen atmosphere. WOis reduced and carbonated to W, WC and WC by sintering, and a cutting tool for Inconel processing excellent in durability can be made by setting WC at 50 mass% in the same, WC amount in the sintered body at 0.44 mass% to 3.85 mass%.SELECTED DRAWING: Figure 5 |
