Question 1

Which laser power should I choose for my sheet metal thickness?

Accepted Answer

Match power to your thickest regular production material, not the occasional maximum. 1.5kW-2kW suits up to 6 mm mild steel and 3 mm stainless. 3kW-4kW handles 12-16 mm mild steel and 8 mm stainless economically. 6kW is the practical starting point for 20 mm plate, while 12kW-30kW is intended for 25-40 mm plate and very high-speed thin-sheet production using nitrogen bright cutting.

Question 2

What is the difference between a single table and an exchange table fiber laser cutting machine?

Accepted Answer

A single table machine uses one fixed bed, so loading and unloading happen while the laser head is idle. An exchange (dual pallet) table shuttles two beds: one sheet is cut while the next is loaded, typically recovering 20-35% more spindle-on time per shift. Exchange tables are recommended above roughly 6 hours of daily cutting or for nested job-shop work with frequent sheet changes.

Question 3

Can fiber lasers cut reflective metals such as copper, brass and aluminium?

Accepted Answer

Yes. The 1064 nm fiber wavelength is absorbed far better by highly reflective metals than a CO2 beam. With back-reflection protection in the laser source and the correct cutting head optics, our machines process aluminium, brass, copper, galvanised steel and titanium in addition to mild and stainless steel.

Question 4

What are the running costs of a fiber laser cutting machine?

Accepted Answer

The main operating costs are electricity, assist gas and consumables. A 3kW machine typically draws 11-14 kW total including chiller and extraction. Oxygen is used for thick mild steel, nitrogen for oxide-free stainless and aluminium edges. Consumables are limited to nozzles, protective windows and ceramic rings; there are no lamps, mirrors or laser gas to replace as with CO2 systems.

Question 5

Do you provide installation, operator training and spare parts support for export orders?

Accepted Answer

Yes. Every machine ships with foundation and utility drawings, sea-worthy packing, commissioning support, trial cutting of customer samples, operator and CAM nesting training, and a documented spare parts list. Remote diagnostics and video-assisted troubleshooting are available for overseas installations, along with recommended first-year and second-year spares kits.

Question 6

Can Marvel Industrial Solution build a custom special purpose machine for our part?

Accepted Answer

Yes. Special purpose machines such as auto metal polishing systems, gantry robot loaders, stamping press transfer robots and material handling lines are engineered from your part drawings, cycle time target and available floor space. The process covers concept layout, simulation, build, factory acceptance testing and on-site integration with your existing presses or machines.
