Custom aluminum machining for medical robots CNC machining of aluminum alloy parts

The technical method of aluminum alloy auto parts processing:

1. Machining datum selection: machining datum should be consistent with the design datum, assembly datum, and measurement datum as far as possible, and the machining process should give full consideration to the stability, positioning accuracy, and clamping reliability of the parts.

2. Rough machining: As the machining dimensional accuracy and surface roughness of some aluminum alloy parts are not easy to meet the requirements of high precision, some parts with complex shapes need to be rough machined before processing and cut in combination with the characteristics of aluminum alloy materials. The heat generated in this way will lead to cutting deformation, increase the error of part size in different degrees, and even lead to deformation of the workpiece. For the rough machining of generally flat surfaces, milling and planing are used. Coolant is added to cool the workpiece to reduce the impact of cutting heat on machining accuracy.

3. Finishing machining: In the processing, high-speed cutting will produce a large amount of cutting heat, although the debris can take away most of the heat, the blade can still produce a very high temperature, due to the low melting point of aluminum alloy, the blade is often in a semi-molten state so that the strength of the cutting point is affected by high temperature, easy to produce aluminum alloy parts in the process of forming concave and convex defects. In the finishing process, usually choose the cutting fluid with good cooling performance, good lubrication performance, and low viscosity. In lubricating tools, timely take away the cutting heat, reduce the temperature of tools and parts processing surface, and reduce the temperature deformation of parts.

4. Reasonable choice of tools: Compared with ferrous metals, aluminum alloy materials produce relatively small cutting forces in the cutting process, you can use a larger cutting speed, but it is easy to form a chip tumor. The thermal conductivity of aluminum alloy is very high. Due to the high heat of debris and parts during the cutting process, the temperature of the cutting area is low and the durability of the tool is high, but the temperature rise of the part itself is faster and easily causes deformation. Selecting the right tool material, choosing a reasonable tool angle, and improving the surface roughness of the tool are very effective in reducing the cutting force and cutting heat.

5. Use heat treatment and cold treatment to solve the processing deformation: heat treatment methods to eliminate the processing stress of aluminum alloy materials include: artificial promptness, recrystallization annealing, etc. The simple structure of the parts process route is generally used: rough machining, manual just-in-time, and finishing. For the process route of parts with complex structures, generally use rough machining, artificial promptness (heat treatment), semi-finishing, artificial promptness (heat treatment), and finishing. While arranging a manual just-in-time (heat treatment) process after roughing and semi-finishing, a stable heat treatment process can be arranged after finishing the part to prevent small dimensional changes in the process of part placement, installation, and use.

Aluminum alloy parts processing five kinds of methods:

1. Aluminum alloy parts stamping processing

Stamping is the workpiece-forming processing method of applying an external force to plates, strips, tubes, and profiles through presses and dies to produce plastic deformation or separation according to the shape and size of the required workpiece.

2. Aluminum alloy parts mechanical processing

Mainly with turning, milling, planing, drilling, grinding, and other general-purpose machine tools to process mold parts, assembled into a variety of molds. Aluminum alloy parts machining can also be called CNC precision machining or automatic lathe machining, CNC lathe machining, etc.

3. Aluminum alloy parts precision casting

Parts obtained by this method generally do not need to be machined again. Precision casting is higher than the shape and casting accuracy obtained by traditional machining methods.

4. Aluminum alloy parts powder metallurgy

Powder metallurgy is the technology of using metal powder as raw material, through mixing, molding, and sintering to manufacture materials or products.

5. Aluminum alloy parts injection molding

The solid powder and organic binder were evenly mixed, after granulation, and then a heated plasticized state injection molding machine was injected into the mold cavity curing molding, chemical or thermal decomposition of the binder in the forming blank to remove, sintered densification to get the final product
