Combination laser cutting system ideal for sheet/tubular components

BLM Group’s LT Combo ‘combination’ laser cutting system is designed for laser cutting of both sheet and tube in cases where production volumes are small or factory floor space is restricted. This versatile ‘two-systems-in-one’ solution provides automatic laser cutting of tube from 16-225mm diameter and sheet

ranging in size from 3,000mm x 1,500mm to 3,000mm x 8,000mm. It takes less than three minutes to change automatically from a tube machining configuration to flat steel sheet machining – and vice versa. With a modular design, the LT Combo can be configured to suit individual requirements in terms of productivity, floor

space and degree of automation involved. This makes the LT Combo highly suited to job shops where short batch runs are the norm or for longer-run production applications within sub-contractors and OEMs. these situations, unmanned machining is possible because of Often in

automation levels up to the integration of multi-column pallet warehousing. › Tubes up to 225mm diameter and flat st eel sheet up to 3,000mm by 8,000mm can be machined on the BLM Adige LT Combo laser cutting system An integral database with a complete range of cutting parameters guarantees repeatability of cutting quality, with the machine control generating the optimum working parameters (cutting power and speed) at any point in the machining cycle. Machining of flat sheet is completed to a positioning accuracy of 0.05mm and a positioning repeatability of 0.03mm, while 3D design and programming of tubular components and complex tubular structures (frames) is simplified with Adige CAD/CAM Artube software. Programs can be completed in minutes rather than hours, drastically reducing the time and cost of translating a completed design into a prototype or a full-scale production component. The end result in either case is improved product quality, especially when the opportunity is taken to re-engineer existing designs of sheet/tubular structures to gain the maximum benefit from the dimensional and profiling accuracy of the LT Combo laser cutting system.

Cut-off machines for optimising production capacities Sinico SpA, Italy, produces flexible, modular machines for use in the automotive, bicycle and motorbike industries. These machines can be used for hydraulic components, electric motors and power transmissions, chains, earth moving machinery and contract machining.

The cut-off unit features the AVTC™ electromechanical drive system, that allows a constant amount of material to be removed by continuously varying the feed speed. The software automatically generates the ISO program for the ideal cutting speed curve based on the set type of tube (size and shape). company’s

› Sinico’s cut-off machine can be used to manufacture parts from 10-40mm in length

The main advantages are reduced cutting time, increased service life of the saw blade, reduced noise levels, and the ability to use saw blades with carbide inserts. Parts can be produced in lengths from 10-640mm, with diameters ranging from 3-120mm. The stock length of loaded bars is from 3-6.5m as standard, or up to 12m on request.
