Turn engineering plastic stock into custom components with pockets, holes, steps, and shaped surfaces.
CNC milling uses programmed cutting tools to remove material from a solid blank. The right approach depends on the polymer grade, component geometry, tolerances and operating conditions.
CNC (Computer Numerical Control) milling is a subtractive manufacturing process in which a rotating cutting tool removes material from a workpiece to produce a specified shape. A programmed machine controls the tool and workpiece movement along multiple axes. Standard machines operate on three linear axes (X, Y, and Z), while four- and five-axis machines add rotational movement to reach more complex surfaces and reduce the need to reposition the part.
Machine more than an outline
Create pockets, stepped faces, and hole patterns within one component.
Develop parts without a mould
Machine from stock while assessing prototypes or evolving a design.
Work with high-quality engineering polymers
Use the best temperature-, chemical-, and wear-resistant materials for your project needs.
Specify critical dimensions
CNC machining creates accurate and correct tolerances in every component.
PEEK
It's high dimensional stability and melting point means it can handle mechancial stress and high-speed cutting tools.
Nylon / PA
Polyamide can cut cleanly into components, however heat and moisture absorption management is required to maintain quality and tight-tolerances.
PE / PP
Both these materials require careful temperature management to avoid melting or burr deformation during the machining process.
Reinforced Polymer: PEEK GF30, RENY, PA66 GF60
Specialist end mills are required to reduce abrasions damaging tooling. Feed rates and spindle speeds must be adapted to avoid delamination.
Acetal / POM
POM's high crystallinity offers a hard cutting edge that creates a clean edge. Its relatively high melting point avoids immediate thermal degradation.
PTFE
PTFE is unable to be injection moulded, so it is CNC machined. It requires suitable clamping and sharp tools to avoid smearing damage.
PEI / PPS
Both these materials are dimensionally stable enough to be CNC machined to a tight tolerance
Milling suits many parts with flat faces, pockets and features at different depths.
