In CNC treatment, if it is a normal dry cut, it is reasonable that almost all steel cuts are purple. Today we will talk about changes in the color of the iron mouths in CNC treatment.
With the improvement of the cutting temperature, the changes in the color of the iron stumps during the dry cut are: silver white → light yellow → dark yellow → dark blue → blue → gray blue → white gray → purple black. Temperature changes can drop from around 200 ° C to more than 500 ° C.
The process of modifying changes in color of the iron mouths is the process of most merits consumed in the cutting process in the heat cutting process. Passivation process – Scrap) (no accumulation) Process (no accumulation) inda) note that the cutting temperature that we generally call refers to the average temperature.
Dedication color and cutting temperature relationship:
Silver white: <200 ° C below
Light yellow: 0220 ℃
Dark blue: ≈300 ℃
Light gray: 400 ℃
Dark and black purple:> 500 ℃
When the cut color is blue or blue -purple, it is reasonable. Using high speed steel tools, it is advisable to cut it into silver and slightly yellow.
Of course, determining that the reasonable parameter is only one of the methods or means by changes in color.
