1、 Selection of surface processing method selection of surface processing method selection of surface processing method selection of surface processing method:
The selection of surface processing scheme shall be based on the machining accuracy required for each surface of the part
According to the surface roughness and structural characteristics of parts, the corresponding processing methods and schemes are selected.
1. According to the technical requirements of the machined surface, the economical machining precision scheme should be adopted as far as possible.
2. According to the properties of workpiece material and heat treatment, select the corresponding processing method.
For example: quenching steel finishing to use grinding, computer gongs processing, Dongguan computer gongs processing, Shenzhen computer gongs processing, mechanical parts processing, Guangzhou computer gongs processing of non-ferrous metals, in order to avoid blocking the grinding wheel during grinding, adjust the cutting method such as fine turning or fine boring.
Consider the structure, switch and size of the workpiece.
4. Productivity and economy are considered in combination with production type.
5. Consider the existing equipment and technical conditions of the plant (or workshop).
2、 Division of processing stage division of processing stage division of processing stage division of processing stage:
When the machining quality of parts is high, the whole processing process should be divided into the following stages:
1. Rough machining stage rough machining stage rough machining stage rough machining stage
The main task is to remove most of the machining allowance, so how to obtain high productivity should be considered.
2. Semi finishing stage. Computer gong processing, mechanical parts processing, CNC machine tool processing, Dongguan high-speed computer gong processing, complete the secondary surface processing, and prepare for the finishing of the main surface.
3. Finishing stage finishing stage finishing stage finishing stage finishing stage finishing stage. Make the main surface meet the quality requirements specified in the drawing.
Finishing stage finishing stage finishing stage finishing stage finishing stage finishing stage finishing stage. In order to further improve the dimensional accuracy and reduce the surface roughness value, it is necessary to finish the surface with high quality requirements.
3、 Process centralization and decentralization process centralization and dispersion process centralization and dispersion: process centralization and process dispersion are two different principles for determining the number of operations when drawing up a process route.
4、 Arrangement of processing sequence arrangement of work sequence arrangement of work sequence: the machining process route of complex workpiece must go through cutting, heat treatment and auxiliary processes.
Therefore, when drawing up the technological route, the technologists should take the cutting, heat treatment and auxiliary processes into consideration.
5、 Selection of machine tool and process equipment selection of machine tool and process equipment selection of machine tool and process equipment
1. Selection of machine tool equipment selection of machine tool equipment selection of machine tool equipment selection of machine tool equipment.
2. Computer gong processing, mechanical parts processing, CNC machine tool processing, Dongguan high speed computer gong processing, process equipment selection, process equipment selection, process equipment selection.
