Metal cutting machine processing high temperature alloy easy to use?

Although metal cutting machine has many advantages, but not for all materials can be very good finishing cutting, such as high temperature alloy. Use metal cutting machine processing high temperature alloy is a not easy thing, in the process of operation will be known to ask what to say so.

1。 Work hardening tendency.

2。 Materials thermal conductivity. Not improved processing units of high temperature alloy cutting force in more than 4000 n/was, and ordinary alloy steel 2500 n/was only. 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. Work hardening phenomenon has a great influence on the oxidation of apex tap life, often produce the boundary of the serious wear and tear. 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 influence of high docile large cutting force, will cause the cutting edges produce plastic deformation, adhesion and diffusion wear. Like not strengthen treatment of GH4169 was investigated about HRC37 matrix hardness, metal cutting machine cutting after surface will produce a 0. 3 mm or so of hardening layer, hardness increased to about HRC47, hardening degree as high as 27%.

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。 Chromium and nickel base alloy ingredient for nickel, also have small amounts of other elements added: tungsten, molybdenum, tantalum, niobium, etc. , keep in mind, the 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.

the above is the use of metal cutting machine processing cutting the difficulty of high temperature alloys, in the hope that we can avoid after operation of high temperature alloy processing
