How to control the mechanical hardware parts machining surface roughness

In the mechanical hardware parts processing industry, the workpiece surface roughness, also known as finish, the general precision Machining Parts of the surface roughness requirements are relatively high, in the Machining process, how do we control the mechanical hardware parts processing surface roughness! Our company specializes in mechanical hardware parts processing industry for many years, has accumulated some processing experience to see the impact of mechanical processing surface roughness of what factors? The following sums up some points ...

1. The amount of cutting: refers to the cutting feed can be, may be appropriate to reduce the amount of surface processing.
2. The choice of tool geometry parameters: from the processing tool geometry parameters, may be appropriate to reduce the sub-deflection angle and increase the radius of the nose, if necessary, grinding grinding edge. Making cutting easy and reducing surface roughness.
3. Control machine vibration: from the tool to reduce the friction between the workpiece, squeeze on the start, so that the tool sharpening sharp, filling the cutting fluid and some of the toughness of the workpiece material for proper heat treatment.
4. Choose a reasonable processing technology: the precision machinery parts processing process, the processing process is also very important, such as unreasonable process may affect the processing quality and production efficiency. Many precision machined parts require rough finish finishing finish finish finish.
5. Different choice of raw materials: mechanical equipment spare parts, composed of many different raw materials processing, according to the different density of raw materials, processing tools and machine tools directly related to the use of surface roughness.
