Carbon fiber is a new type of fiber material with a carbon content of more than 95%, high strength and high modulus. Among them, those with a carbon content of more than 99% are called graphite fibers. It is a microcrystalline graphite material obtained by stacking organic fibers such as flake graphite microcrystals along the axial direction of the fiber and undergoing carbonization and graphitization treatments. Carbon fiber is “flexible on the outside and rigid on the inside”. It is lighter than metallic aluminum, but stronger than steel. It is corrosion-resistant and has high modulus. It is an important material in national defense and civilian applications.
CNC milling is just one method of making parts and can be used in a variety of applications. Below are just some of the most common application areas:

CNC milling is a manufacturing process that uses a rotating tool to advance the tool into the workpiece to remove material from the workpiece. This process can be accomplished using a variety of machine tools, including milling machines and machining centers. After the advent of computer numerical control (CNC) in the 1960s, milling machines evolved into machining centers, which are milling machines equipped with an automatic tool changer, a tool magazine or carousel, CNC capabilities, a cooling system and a housing. CNC milling is a subtractive manufacturing process that uses a 3-, 4-, or 5-axis milling machine to cut solid plastic and metal blocks into final parts. The workpiece is mounted on the workbench, which moves or rotates in different planes so the tool can work at multiple angles. Precision CNC mills can have 5 or more independent axes of motion to create more complex shapes or to avoid moving the workpiece to a separate machine. CNC milling technology allows the processing of parts from a variety of materials, including metals and plastics. CNC milling is suitable for producing high-precision, high-tolerance parts in prototypes, one-offs, and small to medium-sized production runs. CNC milling is suitable for manufacturing general parts and components such as gears and shafts.
Choose the right material: CNC milling services can machine a variety of materials, including aluminum, brass, copper, stainless steel, steel alloys, titanium, ABS, acetal, CPVC, Delrin (POM), HDPE, and LDPE. Choose the material that best suits your needs.
Design the part: Use CAD software to create a 3D model of the part to be milled. Make sure to include all necessary details such as dimensions, tolerances, and surface finish.
Choose the right CNC mill: Choose a CNC mill that can handle the size and complexity of the part. CNC milling machines can have 3-, 4-, or 5-axis milling capabilities.
Set up the machine: Use a clamp or vise to secure the metal block to the milling machine’s table. Make sure the block is level and secure.
Program the machine: Use G-code to program a CNC mill to cut blocks of metal based on the 3D model you create. The G-code will tell the machine where to cut, how deep to cut, and how fast to cut.
Test program: Before milling the final part, run a test program to ensure the machine is cutting the block of metal correctly.
Milling the Part: After verifying that the procedure is correct, start milling the metal block to create the final part. The machine will cut off excess material until the part is complete.
Finishing parts: After milling, parts may require additional finishing processes, such as polishing or coating, to achieve the desired surface finish.
