2019 saw the development of the new cold circular saw family “RAPTOR” launched by Linsinger. The manufacturer of heavy circular saw and milling machines based in Steyrermühl, Upper Austria, is expanding its product portfolio with thin-cut circular saws for mass cutting applications especially for the steel industry.
In its 80-year existence, LINSINGER has been able to place over 400 large circular saws for a wide variety of applications on the global market. In the past 20 years, the company has even managed to attain the leading position, with 90% market share, in the sawing of forged railway wheels and axles.
The know-how gathered in this multitude of projects is now applied in the new RAPTOR product line, together with numerous innovations and technology advancements. The stable construction of the mechanical components, together with Linsinger’s in-house competence center developing and building gearboxes, guarantee durability and low costs per cut.
In this new machine type, LINSINGER completely refrains from using hydraulics. As a result, bulky components such as pumps, pipelines, hoses, or accumulators are completely eliminated. The removal of hydraulics allows for a quieter machine overall, with a significant reduction in noise pollution. Over the life cycle of the machine, the cost of consumables in the form of hydraulic oil, seals and filters is further reduced. The reduced risk of pollution caused by leaking oil, fires or accidents at work underlines the "green philosophy" of this machine once again.
In the future, the RAPTOR family will only use low-maintenance electromechanical components with high energy efficiency. These also allow best positioning and repetition accuracy to be achieved. In combination with thin-cut circular saw blades, optimum utilization of the material over the entire length is guaranteed.
"The properties of modern electromechanical components have led us to take the step away from hydraulics with the RAPTOR. The RAPTOR impresses in terms of modularity, clean maintenance and condition monitoring of individual machine components and offers our customers significant advantages. Today, more than ever, we are driven by the idea of caring for our environment. To this end, we want to contribute by avoiding hydraulic oils and instead utilizing the high energy efficiency of electromechanics," says Dr. Stefan Dierneder - Technical Director of Sawing and Milling Technology at LINSINGER Maschinenbau.
Cycle times can also be substantially reduced by the properties mentioned. For example, depending on the material dimension, the clamping jaws of the machine can be prepositioned into an optimized initial position much more simply. As a result, time is saved with each sawing cycle. The clamping force can be varied depending on the material or wall thickness (e.g., in pipes or profiles) and thus helps to prevent deformation.
A look at the serviceability of the hydraulic-free machine is also worthwhile. In an electromechanical system there are fewer wear parts than in a hydraulic system. Many potential sources of error such as valves, filters and seals are not present. Troubleshooting is easier. In addition, the machines are equipped with a remote diagnosis system. Defective components can be replaced and reintegrated into the system in a short time without draining hydraulic oil. Machine downtimes are thus shortened and can be further minimized by intelligent spare parts management. Machine availability is increasing.
RAPTOR - CONDITION MONITORING
In times like these, modern mass cutting plants understand the rule: "Time is money". Unforeseen machine stoppages are therefore a circumstance which must be avoided as far as possible.
The simple integration of electromechanical actuators into the electrical control of the circular saw, as well as the multitude of available sensor options, in conjunction with intelligent evaluation algorithms, make extensive condition monitoring possible. With modern integrated sensors, for example, all spindle elements of the saw and the transmission are constantly monitored. The diagnostic system of the machine evaluates the collected data and informs the machine operator in good time about measures to be taken to avoid an expensive, unplanned shutdown.
LINSINGER TOOL TECHNOLOGY - TOOL AND MACHINE FROM A SINGLE SOURCE
20 years ago, LINSINGER took a bold step. The manufacturer of special machines and equipment for the steel industry created an in-house tool technology center.
In today's production industry, machine costs are calculated in life cycles (life cycle costs). We found the running costs for tools, calculated over the life of the machine, amount to a multiple of the investment price of the machine.
LINSINGER also takes responsibility for the complete solution of machine and tool from a single source. The machine know-how and the specially tailored tools enable LINSINGER to provide the customer with a reliable view of the tool costs already in the project planning. When commissioned in-house, this package is further refined and precisely tailored to customer requirements. This eliminates the need for lengthy tests after commissioning at the customer. Production runs, in the shortest time, with the agreed output.
Should there be a need for further optimization at a later point in time, there is no need for lengthy third-party discussions where the customer could suffer, the partnership with Linsinger provides the optimum solution. LINSINGER, working as sole supplier, is solution-oriented and offers comprehensive after-sales support via our service technicians and tool specialists worldwide.
