Custom Car Parts

Today, we are going to introduce a Custom Car Parts for the auto motor. TThis custom cnc milling part requires two-time machining,so cnc machining prices will be expensive whose process needs to be handled with more care than that of one-time machining, so it is a big challenge for both the operators and engineers of a custom CNC machining service provider. Let’s find out how Yijin Hardware has successfully manufactured this custom CNC milling part.

Product dimensions: Φ190mm*60mm

Product material: casting aluminium

Product introduction: Electric vehicles have been widely accepted by consumers all over the world gradually. According to the current world-wide situation, Japan is one of the few countries with the fastest development of electric vehicles. Especially in the product development of hybrid electric vehicles, Japan is leading the whole world. Next, Yijin Hardware is going to share the CNC milling on seal covers for auto motors with you. This part is a semi-finished product after previous pressure casting, and next Yijin Hardware will complete the rest of machining for this part by using cnc milling and tell how to reduce cnc machining prices

Cautions for the Custom CNC Milling on Seal Covers for Auto Motors

This custom CNC milling part requires two-time machining whose process needs to be handled with more care than that of one-time machining. Because the custom car parts is clamped twice, there must be an error due to repeated positioning. Therefore, the accuracy of custom car parts may be unstable during machining. To solve the problem of large repeated positioning error, Yijin Hardware suggests that a custom dedicated fixture be used for part clamping.

1)In order to keep directional consistency between the custom car parts setup orientation, the machine tool’s coordinate system, and the programming coordinate system, the fixture should provide guaranteed directional setup. A certain coordinate dimension relation is also required to be maintained between the part’s locating surface and the machine tool.

2)In order to keep all of the surfaces to be machined in this process fully exposed for the workpiece, the fixture should be made open as much as possible. Therefore, a certain safe distance should be kept between the clamping mechanism component and the surface to be machined, and the former is also required to be as low as possible. This is to avoid collision between the fixture and the milling machine tool’s spindle sleeve, cutter case or blade.

3)The fixture must have good rigidity and stability. Try not to use the design which requires the change of clamping points during machining. If it is inevitable, pay extra attention to avoiding the damage of fixture or tool positioning accuracy due to the change of clamping points.
