Extrusion: Servo Cutter for Pipe, Profile, Tubing
Brushless AC servo motors with a fully digital multi-axis control system generate precise cuts at high speeds.
Debuting next month at K 2019, Gillard Cutting Technology of England will show a Servo-Torq Plus cutter that combines the latest Lenze brushless AC servo motors with a fully digital multi-axis control system to activate the rotating knife blade. According to Gillard, this generates precise cuts at high speeds. A new Siemens widescreen touch panels allow easy operator control of the machine.
The new Servo-Torq cutters are available with maximum cutting capacities of up to 150 mm dia. Integral twin-belt Accra-Feed caterpillar infeeder/puller machines are provided to match every cutter model. These feature direct drive AC motors amd planetary gearboxes. Gillard says that this gives improved speed control at high extrusion speeds.
A high level of connectivity is standard as well as Industry 4.0 cloud support. Remote service is available via the Internet using the built-in VPN router. ProfiNet communications allows networking with the rest of the extrusion line.
If a little cooling is good, is a lot of cooling better?
Die buildup, also called die drool, die bleed, or plate-out, can plague any extrusion process.
A poorly designed profile die—one that does not permit the part to be extruded with the same dimensions from run to run—coupled with a lack of understanding of the extrusion process, is a recipe for scrap generation.
