CNC machining is descended from the traditional manual machining, is based on general CNC lathe and the electronic control system, computer data cad design of 3 d design of product research and development of new CNC lathe processing. Because of the high and new technology trend of sustainable non standard fasteners development, the contemporary industrial supplies demand more and more high precision parts, parts of the robustness and precision is higher and higher standard, therefore, automation technology CNC machined into the development trend of the development of industry. Under the To introduce the difference between traditional manual machining and CNC machining.
Processing processing technology level; In the traditional manual machining, whether it's accurate positioning, clamping, CNC blade, drilling and other selected level can be simple and easy to solve. But CNC machining is relatively complex, must be in the nc machine program considering the elements in the process, Even if the same processing daily tasks, there are Steel investment casting several plans, CNC machining is also able to carry out processing, together with several processing position at the same time the processing precision can reach + / - 0.01 mm, it is also a PuTongJi processing can't reach.

The clamping process level; In PuTongJi processing, the CNC lathe processing ability of itself is limited, so must be clamped several times during processing. And special fixture must be used, resulting in jig cost is higher, aeriform in improved products The cost. And CNC machining precision positioning clamping is use to regulate the dashboard, the vast majority of situation without special fixture, so the cost is low.
Now each of aluminium alloy shell with high quality requirements, the diversity of products during the whole process of processing must summarize out aluminum alloy shell should pay special attention to the preparation of socket screw plug machining, so when using all need to do well the preparation work?
First to plan ahead for the processing of CNC blade, then determine the aluminum alloy shell clamp method, to give to the engineering drawings and aluminum alloy shell stamping mould material picture to carry out the verification, determine the specifications of the aluminum alloy shell and its appearance is deformation, maintain aluminum alloy shell surface cleaning, to ensure that no iron pin, oil stain, dust, writing aluminum alloy shell processing processes, to pay more attention to the processing of the position of the blade with processing will meet jig. Calibration of aluminum alloy shell jig, calibration After necessary to carry out and firm, to ensure that during the whole process of processing is not easy to produce aluminum shell wrong move.
Aluminum shell before CNC machining, CNC machining core length of the knife, the knife is net weight meets the requirements. Before application should check the knife has no harm, sometimes should be moved around, inspection equipment Stainless steel foundry and automatic control system for peripheral blockage is there. Should be To examine whether numerical control lathe to RunHua before using the application requirements of the time, has been done by the time specification shall be immediately filled.
The most important or security awareness must be, be sure to check the automatic switch situation is not good, if some people to the danger zone of mechanical equipment category.
