Question
Download Solution PDFStatement I): The ceramic tools used in machining of material have highly brittle tooltips
Statement II): Ceramic tools can be used on the hard-to-machine work material.
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFCeramic tools are sintered or powdered metallurgically produced (Aluminium Oxide) tools that are superior to carbide attached to the tool bit by brazing.
- They have less tendency to adhere to metals during cutting.
- Therefore, lower tendencies to form a built-up edge. That’s why ceramic tools can be used on the hard-to-machine work material.
Ceramic tooltips are highly brittle. So, they are usually attached to the shank through epoxy resins. Cutting speed of 4m/min can be achieved by these tools and its hardness is 2200 HV.
Therefore both the statements are individually true.
