The difficulties of laser cutting machine cutting
1. Cutting force is big, high temperature alloy strength is higher than steam turbine alloy steel materials commonly used by more than 30%, under the cutting temperature above 600 ℃, the strength of the data of nickel-based superalloy is still higher than the general steel alloy material. Did not strengthen the processing units of high temperature alloy cutting force in more than 4000 n/was, and alloy steel 2500 n/was only commonly. 2. Data poor heat conductivity, high temperature alloy cutting occurs when a lot of heat cutting apex tap accept by oxidation, point to accept the cutting temperature is as high as 800 ~ 1000 ℃, under the effect of high temperature and large cutting force, will cause a cutting edge occurred plastic deformation, adhesion and dispersion wear. 3. Work hardening tendency: not strengthen treatment of GH4169 was investigated for example about HRC37 matrix hardness, metal laser cutting appearance after boot cut 0 will happen. 3 mm at the mercy of hardening layer, hardness increases to HRC47 mercy, hardening degree as high as 27%. Work hardening has a great influence on the oxidation of apex tap his appearance, which is usually the boundary of the serious wear and tear. 4. Chromium and nickel base alloy principal component for nickel, other also add a few other elements: tungsten, molybdenum, tantalum, niobium, etc. , it is worth noting, tantalum, niobium, tungsten, etc are also used to make hard alloy ( Or high speed steel) Oxidation apex tap the first ingredient, will happen with these apex tap processing high temperature alloy oxide dispersion wear and abrasive wear.
