10 materials for CNC machining prototypes

Compared with 3D printing, the biggest advantage of CNC prototype is the richness and practicality of materials. The main purpose of the prototype is to verify the feasibility of the product design, so the materials of the prototype are also very particular. Each company’s products are different, and the prototype models that need to be made are also different. Therefore, the production materials may also be different, but the main processing materials include the following:

3 axis, 5 axis CNC milling precision machining

The CNC milling machine can process complex shapes of rotating bodies. In milling, the blank is first fixed, and a high-speed rotating milling cutter is used to move the blank on the blank to mill out the required shape and features. Traditional milling is mostly used to mill simple shape features such as contours and grooves. The CNC milling machine can process complex shapes and features. The milling and boring machining center can perform three-axis or multi-axis milling and boring processing for processing: molds, inspection tools, molds, thin-walled complex curved surfaces, artificial prostheses, impeller blades, etc. When choosing CNC milling parts, the advantages and key functions of CNC milling machines should be fully utilized.

Characteristics and main uses of aluminum profiles

Aluminum profiles are classified by use: Aluminum profiles for construction: architectural aluminum profiles mainly include aluminum profiles for doors and windows and aluminum profiles for curtain walls;
Radiator aluminum profile: mainly used for heat dissipation of various power electronic equipment, LED lighting, and computer digital products.
General industrial aluminum profile refers to:
Mainly used in industrial production and manufacturing, such as assembly line conveyor belts, hoists, glue dispensers, testing equipment, shelves, etc., electronic machinery industry and clean rooms, etc.

choice of tools for CNC turning small precision parts

The commonly used CNC turning tools are generally divided into three categories: forming tools, pointed tools, arc tools and three types. Forming turning tools are also called prototype turning tools. The contour shape of the processed parts is completely determined by the shape and size of the turning tool blade. In CNC turning processing, common forming turning tools include small radius arc turning tools, non-rectangular turning tools and thread tools.

Choose the right tool for CNC machining parts

When finishing large parts, in order to ensure that at least one pass is completed and to avoid changing the tool in the middle of cutting, the tool life should be determined according to the accuracy of the part and the surface roughness. Compared with ordinary machine tool processing methods, CNC machining puts forward higher requirements on cutting tools. It not only requires good steel and high precision, but also requires stable dimensions, high durability, and easy installation and adjustment for breaking and discharging performance, so as to meet the high efficiency requirements of CNC machine tools.

Classification and maintenance of milling machines

The milling machine is a wide range of machine tools. The plane (horizontal plane, vertical plane) can be processed on the milling machine; Groove (keyway, T-slot, dovetail groove, etc.); Gear parts (gears, spline shafts, sprockets); Spiral surface (thread, spiral groove) and various curved surfaces. In addition, it can also be used to process the surface and inner hole of the revolving body and cut off the work.

CNC lathe parts processed by milling and cutting

Processing features: side milling, slotting on the shaft surface. For the two parts, four cylinders protruding longitudinally on the shaft surface are milled on the side, and curved grooves on the shaft surface are milled on the side. CNC lathe processing with power tool head, the tiny milling blade mills out flats or grooves of various sizes.
The two products on the left are made of brass. Nickel-plated connector parts are the connectors of data network cables, and the connection plugs of computers or video equipment are common. The outer diameter is 16mm and the length is 25mm. The other copper part is the copper valve core of the flow control valve, with a maximum diameter of 11mm and a total length of 30mm.

CNC Lathe Turning Complex Shape Parts Groove

An example of a larger CNC lathe turned part.
The left part of the picture is a larger stainless steel turning part. Material SUS304, hexagonal opposite side H (height) 45mm, turning thread, turning inner wall, two-level through hole. Although the shape and installation are simple, the machining volume of turning is large. The big picture is attached.

CNC machine tools in processing aircraft parts

When machining on a CNC machine tool, manual tool control is not required, and the degree of automation is high. The benefits are obvious.
⑴ Reduced technical requirements for operators:
A senior worker of ordinary machine tools cannot be cultivated in a short time. However, the training time for a CNC employee who does not need programming is very short (for example, a CNC lathe worker only needs one week, and he will write simple processing programs). In addition, the parts processed by CNC workers on CNC machine tools have higher precision than those processed by ordinary workers on traditional machine tools, and it takes less time.
