Fracturing

” Fracturing” occurs when the cutting forces exceed the strength of the insert’s cutting edge causing catastrophic removal of a large piece of the cutting tool(tungsten tile cutting wheel), as shown in the figure. Several circumstances can cause [Read More]

cutting tool mechanical failure

Extreme temperature fluctuations and mechanical shock may cause thermal mechanical failure. Stress cracks are generally perpendicular to the cutting edge(tungsten tile cutter tool). Thermo-mechanical failure is most likely to occur during the milling operation, sometimes turning large quantities [Read More]

tool failure-build-up edge

   “Build-up edge”  occurs when the extreme forces at the point of contact between the cutting tool (tile cutter tool)and the workpeice weld small particles of the workpiece to the cutting tool(tungsten glass cutter tool). This type of failure is [Read More]
