Machining PE at Wefapress®: precision at every step
At Wefapress® we are experts in the processing of PE (polyethylene). Our process includes various techniques such as sawing, planing, drilling, milling and even welding to ensure that our products are made to our customers’ exact specifications. Each technique has its own specific parameters and requirements to achieve optimal results. From selecting the right cutting speed to choosing the right material for the tool, we pay attention to every detail to ensure the highest quality of our products.
Cutting speed: 40 – 70 m/min
Feed rate: 0.1 – 0.3 mm per revolution
Material: twist drills, pointed drills
Rake angle: 15 – 25 °
Clearance angle: Twist angle approx. 16°, A = 70 – 90°
Remark: Drilling machines or automatic drilling and milling machines, cooling can be done by compressed air. Pulsating drilling produces smoother hole walls and better chip evacuation, it also avoids overheating.
Cutting speed: 200 – 800 m/min
Feed rate: 0.1 – 0.3 mm per revolution
Material: Tungsten steel (18 % tungsten) or carbide
Rake angle: 15 – 25°
Clearance angle: 15 – 25°
Note: Normal milling machines, but especially high-speed routers. Milling tools with a low number of teeth provide good chip evacuation.
Cutting speed: 250 – 450 m/min
Feed rate: 0.1 – 0.3 mm per revolution
Material: tungsten steel (18 % tungsten) or hard metal
Rake angle: approx. 20
Clearance angle: 5 – 30 °
Note: Thickness planes or jointers as used in woodworking. Only sharp knives produce a smooth surface. There should be 4 knives on the shaft.a
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 tipped blades
Remark: Circular saws, the higher the cutting speed, the cleaner the cut surface, height of cutting speed limited by frictional heat (can be influenced by cooling). Band saws (0.5 mm set), curved cutting etc. (feed 0.1 to 0.3 mm at approx. 1000 – 1500 m/min).
