About This Article
Descriptions
The hardness of this roll is 581 Hv. and considered to be difficult for cutting. For the selection of the suitable tools, an experiment on the tool wear is carried out. A summary of the results is as follows. (1) The suitable tools show larger length of the cracks around the vickers cavity than 500μ. (2) Although the cutting temperature is 600℃～700℃ at the cutting speed of 20m/min, the tool failure is mainly caused by the mechanical wear due to the hard carbide particles on the underside of the chip and the surface material of the tool.
