Murata Wiedemann Motorum 2564

A mechanical flywheel punch stores energy in a rotating flywheel and releases it through a clutch-and-brake system to drive the punch ram. Once engaged, the flywheel delivers a fixed force profile — punch velocity and force cannot be adjusted per stroke. A servo-electric drive uses a servo motor to drive the ram directly (through a ball screw or belt), with fully programmable velocity profile per stroke. Advantages of servo-electric: programmable punch velocity enables gentle approach for coated/sensitive materials; no clutch wear or adjustment; energy recovery braking; quieter operation; and precise control of ram position for forming operations. Disadvantages: maximum punch force is limited by servo motor torque vs the flywheel's stored energy reserve.

Auto-index (AI) stations are turret positions equipped with a servo-driven rotation mechanism that rotates the tool holder to any angle under CNC control. Standard turret stations hold tools at a fixed angle set at load time. AI stations allow punching slots, oblong holes, rectangles, and special shapes at any orientation without a separate tool for each angle. On a 64-station turret with 16 AI stations, complex parts with angled slots in multiple directions use one tool set loaded in AI stations rather than multiple fixed-angle tools consuming multiple stations.

Yes, with proper setup. The no-mark repositioning system holds the sheet using clamps with non-marking surface contacts — the sheet can be repositioned across the full 5 x 10 ft work area without the standard workholders marking the finished surface. For punching operations on coated surfaces, the servo-electric drive's programmable punch velocity enables slow approach speed, reducing the shock force at contact that can crack or chip coatings at the punch entry point. Additional measures: polished punch and die surfaces reduce galling; clearance adjustments for coating thickness; and anti-mark tables protect the sheet underside. Complete surface protection on heavily coated materials requires consultation with Murata Wiedemann applications engineering.

The large-station turret position accepts punches up to 4.5 in (114 mm) diameter. This accommodates large round knockouts, large square cutouts, and special-shape punches up to this diameter. For features larger than 114 mm, nibbling (multiple overlapping punch strokes) can produce any profile size in any shape — nibbling is slower but eliminates the need for special large punches. The machine can also be programmed to punch a pilot hole and then laser-cut (if a combination machine) or transfer to a laser for large profile features exceeding the turret's punch capacity.

Both are 25-ton servo-electric turret punch presses. Key differences: Amada EM 2510NT uses Amada's proprietary AMNC controller; Motorum 2564 uses Fanuc 31i — Fanuc is preferred in Fanuc-standard shops. Amada offers 48 stations vs Muratec's 64 stations — more tooling capacity on the Motorum. Amada's maximum sheet capacity is 50 x 100 in (1,270 x 2,540 mm); Motorum 2564 handles 60 x 120 in (1,524 x 3,048 mm) — a meaningful advantage for shops processing full commercial sheets. Amada's tooling ecosystem and application support are larger and more established. Motorum 2564 is typically priced 10–15% lower. For Fanuc-standard shops processing large sheets, the Motorum is the stronger choice; for tooling variety and application support, Amada has the broader ecosystem.
