Large Format Fiber Laser Cutting Machine

Choose a larger format for a defined production task

What the BG technical proposal needs to define

The current STR catalogue identifies BG as an open large-format series. It does not provide a verified BG dimensional, load or cutting-capacity table. Request the following information for the proposed build rather than applying another series' specifications.

BG identity and layout reference: STR's public fibre-laser catalogue, reviewed 22 October 2026. Numerical working areas, laser options, speeds, load limits and tolerances are intentionally left to the BG-specific technical sheet and application review.

Separate stock size, cutting travel and installed footprint

Ask for these dimensions on one coordinated layout. If a proposal includes multiple working zones, extensions or special loading arrangements, confirm their actual configuration and operating restrictions rather than assuming them from the long bed image.

The useful dimension may be width rather than length

A simple rectangular example shows why stock format needs the real part mix. Assume identical 2600 × 1400 mm rectangular parts, a fixed orientation, a 20 mm margin at every stock edge and a 10 mm gap between parts. Compare hypothetical 6000 × 2000 and 6000 × 3000 mm blanks.

Two parts need 2 × 2600 + 10 + 2 × 20 = 5250 mm in the long direction. Two rows need 2 × 1400 + 10 + 2 × 20 = 2850 mm across the width. Area ratio is part count × 2.6 × 1.4 divided by blank area. This is not an optimal nest, yield guarantee or cost forecast. It omits cutting compensation, lead-ins, defects, grain restrictions and process/support constraints; rotation is not evaluated.

Use the example to ask which extra dimension your real nest can use. Compare the purchased-stock price, remaining usable material, processing route and handling effort before deciding that more table area improves the economics.

Plan loading and removal before selecting the envelope

Trace each material state: delivered blank, positioned plate, separated parts and the remaining skeleton. They can require different access, support and movement. Include the heaviest and least rigid relevant pieces, not just the original sheet.

An open bed does not establish unrestricted access during cutting. Confirm the supplied protective arrangement and the approved operating method. Do not assume simultaneous cutting and loading, independent zones or automated handling unless those functions are explicitly included.

Review support, alignment and long-part behavior

Review the delivered structure

The catalogue image shows a long open arrangement. It does not prove modular construction, structural treatment, load capacity or lifetime stability. Ask for the actual assembly and installation method.

Discuss support condition, alignment checks, load assumptions, access and the inspection records associated with the proposed build.

Choose the laser process independently of table size

A large format defines space for the work; it does not define laser power, cutting thickness or acceleration. Select the source, head, gas and control around the material mix and required edge condition, then confirm their fit with the BG layout.

General cutting background: TRUMPF's process explanation describes focus, gas, nozzle, power and feed as related variables. It is not a STR specification or proof of an included control function.

For the power/process question, compare the high-power A configuration discussion. For motion response, see AG. If the drawing requires inclined edges, submit the joint section for an AP bevel review; large format alone does not provide bevel capability.

Bring the grade, stock condition and next operation

Application suitability belongs to the material, configuration and trial result. The large-format label does not establish suitability for every alloy, coating or nonmetal.

Part families worth reviewing on a larger envelope

Inspect representative geometry across the required area

Select a trial that reflects the largest part, critical internal features and repeated work. Agree measurement positions before testing so the acceptance report covers the regions the job will use.

These library images are not BG test records or proof of a large-format capacity. A meaningful BG acceptance report needs the actual drawing, configuration and measured samples.

State the measurement temperature/conditioning procedure where it matters to the agreed tolerance. Use the buyer's drawing and inspection plan; a public machine-axis accuracy claim is not a substitute.

Make the workshop layout part of the proposal

Compare complete routes for the same accepted parts

Compare the current stock/nesting route and the proposed BG route using the same order requirements. Avoid assuming that a larger blank automatically lowers material cost or that a larger nest automatically raises daily output.

• Purchased material: available formats, price, grain/lot constraints, defects, useful remnants and the real nest.
• Processing: programming, piercing, cutting, repositioning and required support/release strategy.
• Handling: plate staging, loading, part sorting, skeleton removal and movement to the next station.
• Accepted result: dimensional checks, edge cleanup, fit, rework and accepted part count.
• Installation and ownership: site preparation, auxiliaries, maintenance access and the actual commercial terms.

Include long-bed service and scrap access

Plan access to the actual support, collection, extraction, guides and auxiliary equipment. The supplied manual should define isolation, cleaning, lubrication, inspection and calibration procedures for the delivered configuration.

Agree the dimensional, supply and acceptance documents

Before ordering, connect the exact BG build to the layout, application test and commercial offer. The delivery plan should identify packing/transport constraints, site preparation, assembly, commissioning and acceptance responsibilities.

List source/head/control, software licenses, auxiliaries, load and work-envelope definitions, installation drawings, sample conditions, inspection records, operator/maintenance training and manuals. State lead time, warranty/exclusions and on-site service scope in the dated agreement.

The current product preview does not establish a shipping-container size, delivery date, warranty period, local certification or service-response guarantee.
