Guangdong machinery processing plant to share with you = surface finishing processing mechanism
Guangdong Machinery Processing Factory has obtained five basic mechanisms that have an impact on processed products after years of processing experience:
(1) The basic geometry of the cutting process of Guangdong Machinery Processing Factory. The single-point turning tool will advance a constant axial distance, and the resulting surface will be on it. When the tool feeds in the vertical direction, a series of sharp points form the cutting The basic shape of the tool.
(2) Guangdong Machinery Processing Factory Cutting efficiency: It has been mentioned that unstable edge will produce a surface with hardened edge segment. This fragment reduces the surface finish. It can also be proved that the use of large feed, small rake angle and low cutting speed under unfavorable cutting conditions, in addition to production conditions will also lead to unstable built-up products, the cutting process becomes unstable instead of continuous cutting in the shear zone , Breakage occurs, uneven intermittent chips appear, and the surface is not smooth enough. This is especially true when processing tough materials.
(3) Guangdong Machinery Processing Plant. The stability of the machine tool: According to certain combinations of cutting conditions, workpiece size, clamping method and relative rigidity of the machine tool structure, instability is caused by tool chatter. Under certain conditions, this vibration will reach and maintain a certain amplitude, and vibration according to other conditions will also occur, unless the cutting prevents considerable damage, otherwise the cutting tool and the workpiece may vibrate. This phenomenon is called chatter, and axial turning is characterized by long spiral belts on the workpiece and short pitch fluctuations on the temporary machining surface.
(4) Effectiveness of chip removal. In intermittent chip production and processing, such as milling and turning of brittle materials, it is expected that the chips will leave the cutting zone regardless of gravity or cutting fluid, and will not affect the cutting surface under any circumstances. Continuous chips are obvious. If no measures are taken to control the chips, it may affect the cutting surface and leave marks. Inevitably, this signifies what can only be expected.
(5) Guangdong Machinery Processing Factory Effective relief angle of cutting tools: For small cutting edges and relief angles with a certain geometric shape, it is likely to cut on the main cutting edge and polish on the secondary cutting edge. This produces good surface accuracy, but of course this combination of strict metal forming cannot be recommended as an actual cutting method. However, due to these occasions, tool wear will cause changes in surface characteristics
