Six characteristics of 316L stainless steel angle cutting

Because of the 316L stainless steel angle plastic deformation, high ductility, thermal expansion coefficient and other characteristics, 316L stainless steel angle cutting production processing difficulty factor is relatively high, its cutting production processing has six characteristics must pay attention to

First, the cold hardening is more serious: due to the plastic deformation of stainless steel plate, plastic deformation when the character distortion, strengthening index is very large. Coupled with the chemical residues in the cutting heat effect, easy to dissolve is diffuse throughout, which prompted the 316L stainless steel angle in cutting production processing is very easy to produce “hard bottom layer. Before – the first knife or a process caused by the cold work hardening condition will also be more serious impact on the smooth implementation of the process afterwards.

Second, the cutting force: 316L stainless steel angle in the cutting process plastic deformation is large. Promote cutting resistance to enhance. At the same time, 316L stainless steel angle more serious plus I hardened with a higher thermal compressive strength to further expand the cutting resistance, cutting the roll fracture is also more difficult. Thus, the production and processing of 316L stainless steel angle cutting resistance is large.

Third, the cutting temperature is high: 316L stainless steel angle cutting plastic deformation, its friction with the CNC blade is very large, resulting in more cutting heat: coupled with the high heat transfer coefficient of stainless steel plate, a lot of cutting heat is concentrated in the cutting area and the knife – chip touching the page, the heat exhaustion standard is weak.

Fourth, cutting is not easy to fracture, easy to bond: 316L stainless steel angle car production processing cutting stretches. At high temperatures, high pressure, 316L stainless steel angle and other metal materials, strong affinity, easy to cause adhesion conditions, and chip tumors, both aggravate the damage to the CNC blade, and will occur pulling conditions and thus have been produced and processed surface malignant.

Fifth, the CNC blade is easy to damage: cutting 316L stainless steel angle in the whole process of affinity effect, so that the knife and cutting between the bonding, spreading, and then the CNC blade caused by bonding damage, spreading damage, resulting in the CNC blade before the edge of the crescent pits, cutting edge will continue to produce fine shedding and vacancies; coupled with the 316L stainless steel angle in the carburized body particles of high strength, cutting immediately with the CNC Blade touch, friction, rubbing CNC blades, cold hardening conditions aggravate the CNC blade damage.

Six, the coefficient of thermal expansion: 316L stainless steel angle coefficient of thermal expansion of about 1.5 times the alloy steel, in the cutting temperature effect, very easy to cause thermal deformation, specification precision is difficult to manipulate.
