Plastic milling and turning parts

Plastics for CNC machining by milling and turning

A wide variety of plastics with different properties are used for CNC machining with turning and milling. Plastics are versatile, electrically insulating and easy to machine. They are generally characterized by significantly lower manufacturing costs for turning and milling than the metallic materials. 

The ideal plastic for your turning and milling parts

Our product range includes low-cost standard plastics, engineering design plastics and high-performance plastics for specific requirements. This overview provides you with a compact overview of the materials available at Spanflug and helps you select the ideal plastic for your turned and milled parts. All plastics can be selected for instant price calculation at Spanflug Buy.

Our plastics

Please select the plastic with the optimum fit to your requirements. 

PA6
Polyamide

Material costs: €€€€

Tensile strength: 71 - 80 N/mm²

PA is a construction plastic that is particularly suitable for the manufacture of structural and sliding elements with dynamic loads.

good damping properties
good mechanical properties
good gliding properties
high wear resistance
good machinability

PE-HD
Polyethylene

Material costs:

Tensile strength: 20 - 30 N/mm²

PE is a standard plastic with low strength and hardness and high thermal expansion. PE has excellent chemical resistance as well as good impact strength.

good damping properties
very good chemical resistance
very good electrical insulating properties
applicable up to -50° C

PP-H
Polypropylene

Material costs:

Tensile strength: 21 - 37 N/mm²

PP is a versatile standard plastic. Compared to PE, PP has slightly better mechanical properties, while its chemical resistance is somewhat lower. At temperatures below 0 °C, the plastic is susceptible to impact.

good chemical resistance
very good electrical insulating properties
very low specific weight

POM
Polyoxymethylene

Material costs: €€

Tensile strength: 70 - 78 N/mm²

POM is a versatile engineering plastic with high strength and dimensional stability. Its excellent sliding properties make it particularly suitable for dry friction applications.

very good mechanical properties
very good gliding properties
good creep resistance
very good machinability

PEEK
Polyetheretherketone

Material costs: €€€€€

Tensile strength: 100 - 116 N/mm²

PEEK is a high-performance plastic with particularly high mechanical strength, stiffness and temperature resistance.

very high mechanical strength
very high surface hardness
excellent wear resistance
high thermal load capacity
very good chemical resistance
good radiation resistance
good machinability

PTFE
Polytetrafluoroethylene

Material costs: €€€€

Tensile strength: 15 - 35 N/mm²

PTFE is a high-performance plastic characterized by an exceptionally broad thermal application range from -200 °C to +260 °C. It has a relatively low strength.

very good chemical resistance
very good gliding properties
light, weather and radiation resistant
non flammable
very good electrical insulating properties

PA66 GF30

Material costs: €€€

Tensile strength: 112 - 135 N/mm²

PA66 GF30 is a polyamide reinforced with 30 % glass fiber with improved mechanical and thermal properties than unreinforced PA.

good damping properties
very good mechanical properties
good heat resistance
rather unsuitable for sliding applications
good machinability

PMMA (acrylic glass) Polymethyl methacrylate

Material costs:

Tensile strength: 70 - 76 N/mm²

PMMA / Acrylgals is a transparent plastic with excellent resistance to weathering and UV light.

very good electrical insulating properties
light, weather and radiation resistant
high transparency

PC
Polycarbonate

Material costs: €€€€

Tensile strength: 112 - 135 N/mm²

PC is a transparent plastic with high strength, impact strength and rigidity. PC is characterized by very high dimensional stability. Compared to PMMA, however, it is somewhat less transparent and has a significantly higher scratch sensitivity.

very high dimensional stability
good electrical insulating properties
good machinability
low water absorption
rather unsuitable for sliding applications

PVC-U
Polyvinyl chloride

Material costs:

Tensile strength: 35 - 60 N/mm²

PVC-U, or rigid PVC, has very good chemical resistance, good sliding properties and good mechanical properties.

good gliding properties
flame retardant
very good chemical resistance
very good electrical insulating properties

PVDF
Polyvinylidene fluoride

Material costs: €€€€

Tensile strength: 35 - 55 N/mm²

PVDF is a high-performance plastic that has good thermal resistance and is much harder and stiffer than PTFE.

non flammable
very good chemical resistance
light, weather and radiation resistant
good electrical insulating properties

PE-1000/PE-UHMW
Polyethylene

Material costs: €€

Tensile strength: 20 - 25 N/mm²

PE-UHMW is a standard plastic with low strength and hardness and high thermal expansion. Compared to PE-HD, it has significantly higher toughness and better wear and sliding properties. In addition, this material is suitable for applications in the ultra-low temperature range (-200°C to -270°C).

very good chemical resistance
good wear resistance
good damping properties
very good electrical insulating properties
use down to -270 °C possible
