Servo Feeders in the Manufacturer's Catalogue
A servo feeder advances coil stock by a programmed length each press stroke, and its feed length can change at the control panel instead of by changing gears. The manufacturer's platform catalogue documents the servo branch of its feeding range in three listings this page is built on: the NCF numerical control feeder, the NLF2 3-in-1 NC servo uncoiler-straightener-feeder, and a servo feeder machine listed at 700 mm width class. Every figure below is that catalogue's listing data, stated as published there; the combined-line data is also summarised on the coil feeding lines page.
| Item | Published catalogue data |
|---|---|
| NCF feed precision | Within ±0.03 mm, per the listing's closed-loop computer control description |
| NCF feed programming | 20 groups of different feeding lengths; up to 999 punches per group (listed as an option) |
| NCF feed roll | Hollow roll, hard chromium plated, surface hardness HRC 60 |
| NLF2 material window | 0.3-3.2 mm thickness; 11 levelling rollers |
| Servo feeder (700 mm class) widths | Coil widths 200 / 300 / 400 / 500 / 600 / 800 / 1,000 / 1,200 / 1,300 mm |
| Servo feeder thickness and speed | Max 3.2 mm; feeding speed 0-22 m/min; feed accuracy ±0.1 mm per the listing |
What the Listings Describe
The NCF listing describes a computer closed-loop feeder whose precision is held within ±0.03 mm, with a phase-style feeding function (listed as an option) — twenty stored groups of different feed lengths, each repeatable for up to 999 punches, which is the pattern multi-part and special-product work runs on — three-phase manual speed for setup, a quick-set release device matched to the press cam signal, and direct feed-length input on the controller panel. The 700 mm class servo feeder listing describes high-torque, low-inertia servo drive with a pneumatic release system, automatic, manual and setup modes, a rigid frame and a desk-type control cabinet with a 7-inch touch screen. The NLF2 listing folds the feeder into a combined machine: decoiler, straightener and NC servo feeder in one unit for 0.3-3.2 mm material, its straightening section carried on 11 levelling rollers.
Servo, Roll or Gripper?
- Servo feeder: programmable pitch and stored feed-length groups (the phase-style stored-group function is a listed option on the NCF), set at the control panel instead of by changing gears.
- Roll feeder: the documented listing is servo-driven, its pitch set at the panel.
- Gripper feeder: clamp feeding for short pitches and delicate surfaces, up to the high-speed small-parts work the gripper listings document.
Feeding accuracy is a system figure — feeder, straightener and die pilots together — and the catalogue's per-listing figures above are the starting point, not a line guarantee: the configuration for your coil width, thickness and pitch is confirmed in the written quotation. Upstream of the feeder, the coil is handled by the decoiler and levelled by the straightener.
Frequently Asked Questions
What feed accuracy do the servo feeder listings publish?
The NCF listing states precision within ±0.03 mm under its closed-loop control; the 700 mm class servo feeder listing states ±0.1 mm. Both are the catalogue's figures for those listings, confirmed per configuration in the quotation.
Can one servo feeder store several feed lengths?
The NCF listing describes 20 groups of different feeding lengths, each providing up to 999 punches — the multi-product pattern of its phase-style feeding function, which the listing marks as an option.
What coil widths do the servo feeders cover?
The 700 mm class listing publishes width steps from 200 to 1,300 mm and a maximum material thickness of 3.2 mm; the NLF2 combined unit covers 0.3-3.2 mm material.
Is the servo feeder sold separately or only in a line?
Both patterns are in the catalogue: the NCF as a standalone feeder and the NLF2 as a combined decoiler-straightener-feeder. Lines are quoted as a configuration — see the stamping production lines page.
