2. Apply to high speed feeding, long stroke length feeding, significantly improves productivity and feeding accuracy (within±0.03mm).
3. User-friendly operation panel makes it easier to input amount of feeding length directly. The range of feeding length is from 0.1mm to 9999.99mm.
4. Input 20 sets of different feeding length. Each group provides stamping for 999 times to satisfy the processing and production of special products (option).
5. Manual mode: It is available to input 3 phases manual speed so that users operate easily and freely.
6. Job storage provides maximum flexibility and reduced set-up time.
7. All high-hardness and anti-friction rolls are made from heat-treated alloy steel with hard chrome plating and precision ground. The hardness is up to HRC60.
8. Feeding rolls are power driven through a precision gear train.
9. Servo feeder is generally divided into two categories: pneumatic servo feeder and mechanical servo feeder. The feeding principle of these two feeders is exactly the same; the difference is how to achieve the release action. Our engineers can analyze your application to determine mechanical release or pneumatic release.
10. Set up release angle quickly.
11. All electrical components are from advanced worldwide famous brands, such as Siemens, Yaskawa, Mitsubishi, Schneider etc. stable and efficient.
12. Simple but rugged construction allows a longer lifetime, easy in installation and maintenance.
13. NCF models can combine with the press lines, cut to length lines and stamping systems for coil materials of all manufacturers.
14. Custom and application specific solution is available.
There are a few kinds of coil feeder for middle and low speed mechanical punch machines and pneumatic punching machines. Such as NC servo roll feeder, mechanical roll feeder, air feeder or pneumatic feeder, 3 in 1 uncoiler straightener feeder etc. Air feeder have long history and its structures are simple, price is low, so it has been widely used in sample stamping parts producing area. But it exists many weak points such as can’t ensure precision feeding accuracy, easy failure and need frequent maintenances, consume much air source etc. (Refer to Fig 1)
Mechanical roll feeder is advanced than air feeder, it can ensure precision feeding accuracy, machine is reliable etc. But it also has some weak points such as feeding length is limited, a little complex of installation and operation etc. (Refer to Fig 2)
NC servo roll feeders are very popular all over the world now and widely used in metal stamping parts producing area. NC servo roll feeder was comprised of main machine and control box equipping with servo motor, servo driver system, PLC, HMI etc. (Refer to Fig 3)
3 in 1 uncoiler straightener feeder is usually for above 400mm width coil feeding, high tensile material and thicker material etc. This machine’s feeding part is also driven by servo motor. Controlled by PLC, HMI etc. (Refer to Fig 4)
