The choice of laser cutting machine is a lot of metal processing enterprises.
Compared with ordinary steel, high temperature alloy cutting processing difficulty is mainly manifested in the following aspects:
1. Work hardening tendency. Such as not strengthen treatment of GH4169 was investigated about HRC37 matrix hardness, laser cutting machine cutting surface after 0. About 3 mm 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.
4。 Nickel-based alloy ingredient of nickel and chromium, also have small amounts of other elements added: tungsten, molybdenum, tantalum, niobium, etc. , it is worth noting, tantalum, niobium, tungsten, etc. Is also used to produce cemented carbide ( Or high speed steel) The main components of oxidation apex tap with the oxidation apex tap processing can produce high temperature alloy diffusion wear and abrasive wear.
laser industry development look promising, but with the same industry keeps increasing, the competition is increasing, the laser equipment market oversupply situation. Laser equipment, therefore, the development of electronic commerce do help traditional industrial enterprises to change the mode of production, deeper surface developed another industrial product market, but also avoid the backlog of products, production rules and other problems. Because by purchasing sites for big buyers, usually by big buyers purchasing requirements in terms of production, not only meet the demand of big buyers purchasing standards, more enterprise core suppliers to save fund development technology, improve product performance to guarantee, in order to win more profit growth.
