PE processing


Cutting speed: 3000 - 4000 m/min (for calculating the number of revolutions of your blade diameter)

Feed rate: 0.1 - 0.2 mm per tooth

Material: carbide-coated sheets

Note: Circular saws - the higher the cutting speed, the cleaner the cut surface. Cutting speed limited by frictional heat (can be increased by cooling). Band saws (0.5 mm bevelled), curved cut etc. (feed rate 0.1 - 0.3 mm at approx. 1000 - 1500 m/min).


  • Sägen

PE processing


Cutting speed: 250 - 450 m/min

Feed rate: 0.1 - 0.3 mm per revolution

Material: Tungsten steel (18% tungsten) or carbide

Front rake angle: approx 20°

Clearance angle: 5 - 30°

Note: Planers or dressing machines are commonly used, as in the carpentry industry. Only sharp blades can achieve a smooth surface. Each shaft should have 4 blades.


  • Hobeln

PE processing


Cutting speed: 40 - 70 m/min

Feed rate: 0.1 - 0.3 mm per revolution

Material: Spiral drill, flat drill

Cutting angle: 15 - 25°

Clearance angle: Angle of twist approx. 16°, A = 70 - 90°

Note: Drills/boring and milling machines. Compressed air can be used for cooling. Intermittent drilling creates smoother holes and clears chippings more effectively as well as preventing overheating.

  • Bohren

PE processing


Cutting speed: 200 - 800 m/min

Feed rate: 0.1 - 0.3 mm per revolution

Material: Tungsten steel (18% tungsten) or carbide

Cutting angle: 15 - 25°

Clearance angle: 15 - 25°

Note: Regular milling machines, particularly with high-speed routers. Milling tools with fewer teeth are most effective for clearing chippings.

PE processing


Due to the melt viscosity, Wefapress St 1000 can only be joined together using friction and butt welding techniques.

Butt welding involves heating the clean welding surfaces to 200 - 220°C under low contact pressure until a layer of around 4mm on each side becomes malleable. Under a contact pressure of 10 - 20 kp/cm², the parts are pressed together until cooled.

If the parts for welding are blocks over 30 mm thick, a contact pressure of 50 kp/cm² or more is required. A press or special welding equipment is often used for this purpose.
