1.
Work hardening tendency.
After laser cutting machine for cutting surface will produce a 0.
3 mm or so of hardening layer, hardness increased to about HRC47, hardening degree as high as 27%.
Work hardening phenomenon has a great influence on the oxidation of apex tap life, often produce the boundary of the serious wear and tear.
2。 Materials thermal conductivity. Plenty of cutting heat generated when cutting high temperature alloy by oxidation apex tap, under point under the cutting temperature is as high as 800 ~ 1000 ℃, under the effect of high temperature and large cutting force, will cause the cutting edges produce plastic deformation, adhesion and diffusion wear.
3。 Cutting force is big. High temperature alloy strength is higher than steam turbine steel materials commonly used by more than 30%, under the cutting temperature above 600 ℃, the strength of the material nickel-based superalloy is still higher than ordinary steel materials. Not improved processing units of high temperature alloy cutting force in more than 4000 n/was, and ordinary alloy steel 2500 n/was only.
