Processing Multiple solutions are possible, with multiple machining parts and machining tools as the main line of the process arrangement, the process has a variety of characteristics.10 Data machining process is more complex, need to fully consider these factors, positioning reference, clamping methods, tools, cutting methods and other aspects can be simplified processing10
Clamping and fixtures Clamping process as long as the positioning and clamping of this effective control, positioning can be used to debug the instrument, in most cases do not need to carry out the design of special fixtures, so relatively speaking, its cost is relatively low.10 Due to the limited machining capacity of the machine tool itself, it is necessary to carry out multiple clamping during the machining process. Also, special fixtures are required, which results in higher costs for the design and manufacture of fixtures.10
Tooling Requirements High-speed cutting on the cutting tool demand increases, the use of high-speed cutting to improve machining efficiency, to protect the quality of machining, reduce the chances of cutting deformation, shorten the machining cycle10 General performance requirements for tools10
Applicable Scenarios Suitable for large quantities, complex shapes and precision parts1 Suitable for small-lot, simple part production.1
4 How to choose the right machining service
Bei der Auswahl von Bearbeitungsdienstleistungen gibt es mehrere Faktoren zu berücksichtigen, um ein erfolgreiches Projekt zu gewährleisten:

4.1 Component Complexity
