PEEK CNC Turning

PEEK is a high polymer composed of repeating units containing one ketone bond and two ether bonds in the main chain structure, and is a special polymer material.PEEK has physical and chemical properties such as high temperature resistance and chemical corrosion resistance. It is a kind of semi-crystalline polymer material with a melting point of 343°C, a softening point of 168°C and a tensile strength of 132-148MPa. It can be used as a high-temperature resistant structural material and electrical insulating material. , which can be composited with glass fiber or carbon fiber to prepare reinforcing materials.

PEEK CNC Turning Parts

  • Self-lubricating with low friction coefficient, can realize oil-free lubrication, long-term work in medium such as oil, water, steam, weak acid and alkali.
  • Easy to process Parts can be directly processed by injection molding process. Post-processing such as turning, milling, drilling, tapping, bonding and ultrasonic welding can be performed.
  • Low-smoke and non-toxic combustion, the amount of smoke and poisonous gas is very low.Compatible with ultra-high vacuum applications.
  • High temperature resistance US UL certification Long-term use temperature is 260 ℃, even when the temperature reaches 300 ℃, it can still maintain excellent mechanical function.
  • Wear resistance PEEK compound and its composite materials have excellent wear resistance in many extremely harsh environments such as high temperature, high load and strong corrosion.High strength has the best mechanical strength among plastics. It also has high rigidity and surface hardness.
  • Corrosion resistance, insoluble in common solvents, and has good corrosion resistance to various organic and inorganic chemical reagents.
  • Hydrolysis resistance When soaked in steam with a temperature over 250℃ or in high pressure water, PEEK products can still work continuously for thousands of hours without obvious functional decline.

How PEEK Turning Work


PEEK turning is a precision machining process in which mental stock is held in spindle chuck and rotated while cutting tools remove material by spinning workpiece contact. Computer instructions control machinery movement to create extreme precision and repeatable PEEK parts. PEEK turning is different from CNC milling, in which cutters rotate and direct to stationary work-piece form multiple angles. While PEEK turning rotating work-piece in a chuck, it’s generally to create round or tubular shapes, and achieving far more accurate rounded surfaces than PEEK milling or other machining process.

PEEK turning machines hold material blocks, which is removed to create designed shape by rotated mechanism. PEEK lathe machine tooling is mounted to a turret, this component is programmed with certain movement and removes material from raw material block to desired shape. PEEK turning can be used for rapid manufacture of either prototypes or end-use PEEK parts. CAD file will transfer into a PEEK-readable program G-code in PEEK turning centers, the stock materials is rotating on metal rod, while PEEK turning software control cutting tools remove materials to dictated shape. PEEK turning is typically used to manufacture cylindrical-type forms in straightforward process. PEEK turning can be used for rapid manufacture of either prototypes or end-use PEEK parts. PEEK parts can be left as- machined, or for further bead blasted and finished smooth.

PEEK Turning Operations – Types of PEEK Turning


There are many types of PEEK turning operations for PEEK lathe services can be performed on a live tooling lathe in PEEK turning factory, including Hard turning, Parting, Facing, Boring, Reaming, Taper turning, Drilling, Knurling, Threading, Grooving, etc., comes in varying tools, cost and set-up time.

  • PEEK Tapered turning: produce a cylindrical part of which diameter decrease from one end to another.
  • PEEK Hard turning: suited for materials with a Rockwell C hardness greater than 45, typically performed after heat treated.
  • PEEK Spherical generation: create a spherical finished surface, turning around fixed rotary axis.
  • PEEK Facing: a turning operation in which the workpiece is machined to its center.
  • PEEK Parting: create deep grooves that remove a completed or part-complete component from its parent stock.
  • PEEK Grooving: similar to parting, but only cut to a specific depth from outside or inside of workpiece.
  • PEEK Drilling: remove materials to drill holes from the inside of a workpiece with drill bits held stationary in the tail stock or tool turret of the lathe.Boring: enlarge or smooth an existing hole.
  • PEEK Knurling: cut serrated pattern onto the surface of workpiece with knurling tool, to change or enhance visual effect or hand grip.
  • PEEK Reaming: remove a small volume of materials from a drilled hole, for highly accurate diameters.
  • PEEK Threading: turn standard and non-standard screw threads, generally means single-point threading.
  • PEEK Polygonal turning: non-circular forms machining operation without interrupting the rotation of the raw material.
