CNC Machining PEEK Services
RALLY Provide PEEK machining services
CNC Milling
This process uses rotary cutters to remove material from the PEEK workpiece. It can create a wide range of shapes and is often done on a CNC machine for precision and consistency.
CNC Turning
In this process, PEEK material is rotated while a single-point cutting tool is moved parallel to the axis of rotation. Turning can be performed manually, but it's usually done using a lathe or CNC machine.
CNC Drilling
Drilling creates holes in the PEEK material. The process can be performed with a variety of machine tools, including drill presses and CNC machines.
Common PEEK Machined Parts
PEEK (Polyether Ether Ketone) is a versatile high-performance thermoplastic material used to create a wide variety of machined parts. Its high strength, chemical resistance, and excellent thermal stability make it ideal for numerous applications. Here are some of the most common PEEK machined parts:

Applications of PEEK in machining
PEEK, or Polyether Ether Ketone, is a high-performance plastic that's used across several industries due to its exceptional properties. It's lightweight, strong, and resistant to many types of damage. Below are some specific applications of PEEK in machining:
Aerospace Industry
PEEK's light weight and high strength make it suitable for several aerospace applications, such as components for engines and cabin modules. It's also resistant to flame, smoke, and toxic gases, further enhancing its applicability in this sector.
Electronics Industry
PEEK is used to make connectors, sockets, and insulators because of its excellent electrical properties. It has low dielectric constant and high insulation resistance, which are desirable features in the electronics industry.
Medical Industry
PEEK's biocompatibility, sterilizability, and radiolucency make it ideal for several medical and dental applications. It's used for producing surgical instruments, implants, and components for diagnostic equipment.
Automotive Industry
PEEK is used for making a variety of parts, including gears, bearings, seals, and electric components due to its high wear resistance, low friction, and ability to withstand high operating temperatures.
Oil and Gas Industry
Because of its chemical and heat resistance, PEEK is suitable for components that are exposed to harsh environments in the oil and gas industry, like seals and compressor components.
Food Processing Industry
PEEK is also used for parts in food and beverage processing machinery due to its ability to withstand repeated cleaning and sterilization cycles.
PEEK Machining: A Quick Guide to Machining PEEK
PEEK (Polyether Ether Ketone) is a high-performance engineered polymer that is often used in machining applications due to its excellent mechanical and chemical resistance properties. Here are some frequently asked questions (FAQs) about PEEK machining:
PEEK (Polyether Ether Ketone) is a colorless, organic thermoplastic polymer that boasts exceptional mechanical and thermal properties. It is known for its strength, dimensional stability, and resistance to chemicals, wear, and radiation.
Due to its outstanding properties, PEEK is used in a variety of industries like aerospace, automotive, chemical processing, electronics, and healthcare. It's commonly used to create components that need to withstand harsh conditions, such as gears, seals, pump parts, electrical insulators, medical implants, and more.
PEEK can be machined to precise tolerances, and it maintains its physical properties even in high-temperature environments. It is also resistant to chemicals, wear, and radiation. Moreover, it's a lightweight material making it ideal for applications where weight is a factor.
Machining PEEK requires sharp, hardened tools to ensure a clean cut and to prevent material buildup on the tool edge. Carbide tools are often recommended due to their hardness and heat resistance. The machining parameters such as spindle speed, feed rate, and depth of cut should be carefully set according to the specifications of the part being machined.
While PEEK can withstand high temperatures, it's still important to manage heat during machining. Coolants can be used to prevent overheating, but care should be taken to avoid rapid cooling, which can cause thermal shock. Air cooling is often sufficient for most machining operations.
PEEK is softer and more lightweight than most metals, which can make it easier to machine. However, it also has a high melting point and high abrasion resistance, which can cause wear on tools if not properly managed.
PEEK has excellent chemical resistance, which can make some traditional finishing processes, like painting or coating, more difficult. However, PEEK's surface can be mechanically or chemically etched to improve adhesion for these finishes. PEEK can also be polished to a high gloss if desired.
