What is the General Roughness of the Surface During CNC Machining?

CNC Machining is generally about 3.2 for ordinary machine tools, and high-speed machines can achieve a finish of 1.6; pay attention to the tools and cutting parameters used in machining.

Whether it is Plastic Precision Machining, Steel Precision Machining, Brass Cnc Lathe Machining, Copper Cnc Machining, Aluminum Precision Machining,Titanium Precision Machining, Metal Machining or Grinding Machining Parts .Surface roughness is generally formed by the processing method used and other factors, such as the friction between the tool and the surface of the part during CNC machining, the plastic deformation of the surface metal when the chips are separated, and the high-frequency vibration in the process system. Due to different CNC machining methods and workpiece materials, the depth, density, shape and texture of marks left on the machined surface are different.

Surface roughness is closely related to the matching properties, wear resistance, fatigue strength, contact stiffness, vibration and noise of mechanical parts, and has an important impact on the service life and reliability of mechanical products. Ra is generally used for marking.
