Question 16

How to adjust parameters when cutting different metal materials on a metallographic abrasive wheel cutting machine?

Accepted Answer

When cutting different metal materials with a metallographic abrasive cutting machine, cutting parameters need to be adjusted reasonably.
For metals with lower hardness, such as pure copper and aluminum alloys, the cutting speed can be appropriately increased, and the feed rate can also be appropriately enlarged. Because these metals have a soft texture, the resistance generated during cutting is small; increasing the cutting speed and feed rate can improve cutting efficiency without significantly affecting the quality of the cutting surface.
As for metals with higher hardness, such as stainless steel and cemented carbide, it is necessary to reduce the cutting speed and decrease the feed rate. High-hardness metal cutting generates a large amount of heat; reducing the cutting speed and feed rate can reduce heat generation, avoiding premature wear of the abrasive wheel and changes in the metallographic structure of the metal workpiece due to overheating.
In addition, the flow rate and spraying method of the coolant should be adjusted according to the toughness of the metal. Metals with high toughness are prone to deformation during cutting, necessitating an increase in the coolant flow rate to strengthen the cooling effect.
