CNC Machining Titanium Flange
As a high-precision and high-efficiency processing method, CNC machining provides strong support for the manufacture of titanium flanges and can meet various complex shapes and high-precision requirements. CNC technology includes turning, milling, drilling, grinding, etc.
- CNC Turning
CNC turning is the main process for processing the outer circle, inner hole, end face, etc. of titanium flanges. Through the rotation of the lathe and the feed movement of the tool, the excess material is removed so that the size of the titanium flange meets the design requirements.
- CNC Milling
CNC milling is used to process the plane, groove, keyway and other features of titanium flanges. The material is removed by the relative movement of the rotating tool and the workpiece of the milling machine. Pay attention to the selection of tools and the optimization of cutting parameters.
- CNC Drilling
CNC drilling is the process of making bolt holes or other connecting holes on titanium flanges. According to the size and accuracy requirements of the hole, select the appropriate drill bit and drilling equipment for processing. Such as high-speed drilling, deep hole drilling, etc.
- CNC Grinding
CNC grinding is a process for finishing the surface of titanium flanges to improve surface finish and dimensional accuracy. CNC grinding removes tiny dimensional errors and brings its surface quality to a higher standard.
Forging Titanium Flange
Forging is one of the commonly used processes in the manufacture of titanium flanges. Through forging, the organizational structure of titanium alloy can be improved, and its strength and density can be increased. Forging methods can be divided into free forging and die forging. Free forging is suitable for the production of small batches of titanium flanges with simple shapes. Die forging is suitable for the production of large batches of titanium flanges with complex shapes. Through the constraint of the mold, the blank is accurately formed into the shape and size set by the mold during the forging process, but the manufacturing and maintenance costs of the mold are high.
Casting Titanium Flange
Casting is also a method of manufacturing titanium flanges, especially for manufacturing flanges with complex shapes. The casting process is to melt the titanium alloy into a liquid state, and then inject it into a pre-made mold cavity, and form the shape of the titanium flange after cooling and solidification. The casting process can be divided into sand casting, investment casting, centrifugal casting and other types.
Sand casting has relatively low precision and poor surface quality. Defects such as pores and sand holes may occur, which need to be processed in subsequent processing.
Investment casting, also known as lost wax casting, is suitable for manufacturing titanium flanges with complex shapes and high dimensional accuracy requirements, such as the connecting flanges of some key components in the aerospace field. However, the process of investment casting is relatively complicated and the cost is relatively high.
Heat Treatment
Heat treatment is an important process to improve the performance of titanium flanges. Appropriate heat treatment processes are used to eliminate the internal stress generated during forging or casting, and improve the processing performance and corrosion resistance of the material. Common heat treatment processes include annealing, normalizing, quenching and tempering.
Annealing is the process of heating the titanium flange to a certain temperature, keeping it warm for a period of time and then slowly cooling it. Annealing can improve its plasticity and toughness and improve processing performance.
Normalizing is the process of heating the titanium flange to an appropriate temperature above the phase transition point, keeping it warm and then cooling it in the air. Normalizing can refine the grains, improve the strength and hardness of the material, and improve its comprehensive mechanical properties.
Quenching is the process of heating the titanium flange to a high temperature above the phase transition point, keeping it warm and then cooling it rapidly. Quenching can enable the titanium alloy to obtain a high-strength organizational structure such as martensite, significantly improving the strength and hardness of the material.
