Rolling, rolling knife
Rolling knife is the use of the principle of mechanical extrusion, to obtain a smooth mirror of the metal surface of a mechanical non-cutting plastic processing method. The rolling cutter can make use of the plastic deformation of the metal at room temperature, so that the micro unevenness of the surface of the workpiece can be rolled flat so as to achieve the purpose of changing the surface structure, mechanical characteristics, shape and size. No matter what kind of metal processing tool is used, the surface of the part will always leave fine convex and uneven knife marks, there are staggered peaks and valleys. Rolling knife is the use of the principle of mechanical extrusion, to obtain a smooth mirror of the metal surface of a mechanical non-cutting plastic processing method. Features It is a kind of pressure finishing, is the use of metal in the normal temperature state of the cold plastic characteristics, the use of rolling tool on the surface of the workpiece to apply a certain pressure, so that the surface of the workpiece metal to produce plastic flow, filled into the original residual low concave valley, and to achieve the workpiece surface roughness value reduced. Due to the plastic deformation of the rolled surface metal, the surface tissue is cold hardened and the grains become fine, forming a dense fiber shape, and forming a residual stress layer, which improves the hardness and strength, thereby improving the wear resistance, corrosion resistance and compatibility of the workpiece surface. Rolling is a non-cutting plastic processing method, so this method can achieve both finishing and strengthening purposes, grinding, turning can not do. The rolling tool has no blade, the processing technology is safe and convenient, and can be used in all metal processing industries. It can accurately control the accuracy and has several advantages: 1, improve the surface roughness, roughness can basically reach Ra≤ 0.08um. 2. Correct roundness, ovality ≤ 0.01mm. 3. Improve the surface hardness, eliminate the stress deformation, and increase the hardness by HV≥ 4 ° 4. There is a residual stress layer after processing, which improves the fatigue strength by 30%. 5. Improve the quality of coordination, reduce wear, and extend the service life of parts, but the processing cost of parts is reduced.

Product Description
Rolling knife is the use of the principle of mechanical extrusion, to obtain a smooth mirror of the metal surface of a mechanical non-cutting plastic processing method.
rolling knifeIt can make use of plastic deformation of metal at room temperature to flatten the microscopic roughness of the surface of the workpiece so as to achieve the purpose of changing the surface structure, mechanical characteristics, shape and size. No matter what kind of metal processing.CutterProcessing, in the surface of the parts will always leave fine uneven knife marks, the emergence of staggered ups and downs of the peak and valley phenomenon.rolling knifeIs the use of the principle of mechanical extrusion, to obtain a smooth mirror of the metal surface of a mechanical non-cutting plastic processing method.
Features
It is a kind of pressure finishing, is the use of metal in the normal temperature state of the cold plastic characteristics, the use of rolling tool on the surface of the workpiece to apply a certain pressure, so that the surface of the workpiece metal to produce plastic flow, filled into the original residual low concave valley, and to achieve the workpiece surface roughness value reduced. Due to the plastic deformation of the rolled surface metal, the surface tissue is cold hardened and the grains become fine, forming a dense fiber shape, and forming a residual stress layer, which improves the hardness and strength, thereby improving the wear resistance, corrosion resistance and compatibility of the workpiece surface. Rolling is a non-cutting plastic processing method, so this method can achieve both finishing and strengthening purposes, grinding, turning can not do.
RollingThe tool has no blade, the processing technology is safe and convenient, and it can be used in all metal processing industries. It can accurately control the accuracy and has several advantages:
1, improve the surface roughness, roughness can basically reach Ra≤ 0.08um.
2. Correct roundness, ovality ≤ 0.01mm.
3. Improve the surface hardness, eliminate the stress deformation, and increase the hardness by HV≥ 4 °
4. There is a residual stress layer after processing, which improves the fatigue strength by 30%.
5. Improve the quality of coordination, reduce wear, and extend the service life of parts, but the processing cost of parts is reduced.
