MG Multi-Head CNC Plasma Cutting Machine (3-6.5m Span, Rails to 40m) | Jinfeng, Ningbo, China

MG Multi-Head Plasma Cutting Machine

Jinfeng (Ningbo Jinfeng Welding & Cutting Machinery Manufacture): Cixi, Ningbo, China

CNC gantry cutting machine with a 3 to 6.5m span, rails of 8 to 40m, and one or two torch carriages, for plasma cutting of complex shapes and rapid strip cutting from plate, with optional flame, bevel, and marking units.

The MG Multi-Head Plasma Cutting Machine is a CNC gantry for cutting plate. Its CNC cutting head handles complicated shapes, and with a plasma source fitted it cuts sheet quickly. A straight cutting head cuts strips (steel bars) from steel plate efficiently and with little deformation.

The machine is made in a range of sizes: the span can be anywhere from 3,000 to 6,500mm, the effective cutting width is the span less 800mm, and the rail is 8 to 40m long, with an effective cutting length of the rail less 2m. It has one or two cutting torch carriages, bilateral drive, and uses a plasma source of up to 200A with arc-voltage height control. The plasma dust removal system can be dry, shallow water, or underwater.

The structure is built to hold accuracy: the cross beam and end frames are welded in an automatic welding centre to reduce distortion, and all stressed parts are stress-relieved. Jinfeng says it machines its frames on its own multi-axis CNC machining centres, which keeps the beam parallel to the rail and the holes accurately positioned. The torch base has 360° anti-collision protection and a heavy torch lifter with manual, electric, and automatic height modes, and the machine is controlled by an imported PLC.

Why Choose a Multi-Head Plasma Cutter?

Long rails and multiple torches let one machine cut large plates and long strips efficiently. Choosing the dust removal method (dry, shallow water, or underwater) lets you match the machine to your fume and noise requirements.

• Very long cutting travel. Rails up to 40m for long plate and strip work.
• Flexible spans. 3 to 6.5m to match your plate widths.
• Choice of dust control. Dry, shallow water, or underwater plasma cutting.
• Multiple torches. One or two carriages, with twin and triple torch options.
• Add-on functions. Flame cutting, bevel cutting, powder marking, and inkjet marking.

Frequently Asked Questions

What sizes can it cut?
Spans from 3,000 to 6,500mm (cutting width is span less 800mm), on rails of 8 to 40m.

How many torches does it have?
One or two cutting torch carriages, with optional single flame, twin, and triple torch units.

Which plasma source does it use?
A plasma source of up to 200A. The brand isn't stated (see notes).

How is dust controlled?
The plasma dust removal can be dry, shallow water, or underwater.

Can it cut bevels?
Yes, with the optional flame bevel station (0 to 45°) or rotating contour bevel torch.

Can it mark parts?
Yes, with the optional powder marking and inkjet marking devices.

Is financing or staged payment available?
Yes. A deposit secures your order and begins production, with the remaining balance due only once your machine has been built, inspected, and is ready to ship.

Should I buy new or used?
This machine is available new, built to order.
