Electronics

This product is from European customers .This product is used in the field of electronic products,it’s an instrument case. Material: 6082 T6. The difficulty of machining for this product lies in the case, which is only 1mm thick and easily deformed. After discussion by our technical team, we use aluminum die-casting drawing molds. Product length 55.5mm. It is a big difficulty to make the seal of the case top. We use CNC machining as per the product top drawing make Each size to 1mm thickness, and then we are welded by argon arc welding. Before welding degreasing treatment is required because the thin casing of this product encountered difficulties in the welding process is that the thin casing is easy burning through the product is easy to scrap. Aluminum material dissipates heat quickly, has a high melting point, and has a low material density, so welding is troublesome. Through our unremitting efforts to solve the problem of difficult product welding. Processing technology: the thin shell is not easy to be processed on the machine tool, and it is made by manual grinding after welding. Ensure product welding light leakage is not allowed securely. The length of the drawing is processed according to the picture, and the hole size is accurate at each hole position to remove burrs! Surface treatment: black hard oxidation, this product needs to be protected from the cavity port to the inner wall 12mm four sides Oxidation treatment, we use 3M high temperature resistant tape to protect it before oxidation. It needs to be cleaned up after oxidation. Check whether the appearance requirements are intact. Get praise from our customers. Responsibility for our production and processing, process and technology staff highly rated. Let us do better with high precision and high quality requirements.

Example . Cooling sleeve

skills requirement

1.Material: 45 steel.     2.The acute angle is blunt.     3.Heat treatment: tempering 235HBW.     4.All chamfering C1.

1.Part drawing analysis

1) The part material is 45 steel.

2) The reference is the center line of the outer circle of ϕ175h6.

2.Process analysis

1) The wall of this part is thin, and there are many annular grooves on the outer circle, which makes turning processing more difficult. Be sure to pay attention to clamping deformation.

2)) ϕ175 h6  outer circle has high requirements for dimensional accuracy and coaxiality, and the process arrangement is for grinding.
