Condition: used, Year of construction: 1978, Equipment: documentation/manual, emergency stop, foot remote control, I am offering an electro-hydraulic profile bending machine, purchased in 2012, manufactured by Roundo AB, Sweden, type: R-7S (used, workshop-inspected, and partially refurbished with standard configuration, including vertically arranged bending axes, for sale. It is fully operational and can be demonstrated under power after prior consultation. - Control panel on the swivel arm with joysticks and switches - Digital displays for the two side rollers Significant added value: Extensive tool and profile package included! To be able to handle customer orders in an even more flexible and individual manner, significant investments have been made in expanding the range of tools. In addition to the standard tools, you will receive: • 36 additional rollers for a wide variety of profiles. • Special tool for flat and light-duty profiles up to a height of 500 mm. • Tools for square and rectangular tubes. • Tools for various round tubes Ø (88.9 + 114.3 + 139.7 + 168.3) mm. This machine is designed according to the latest findings in the tube and profile processing industry (as of 2012). The fixed bending roller is equipped with an adjustable slip clutch, which automatically adjusts the speed of the bending roller to the workpiece being bent. The three bending axes are mounted on oscillating roller bearings. A set of complete universal bending rollers for bending angle and T-sections with flange facing inwards and outwards, flat sections upright and lying flat, and square material. The rollers are made of wear-resistant and hardened steel. They consist of three adjustable rings, allowing various profiles to be rolled. Two independently adjustable guide rollers, which can be adjusted fully hydraulically on three different axes. The guide roller unit is equipped with small, interchangeable rollers. This allows asymmetric profiles to be held flat. This is especially necessary for angle sections with the flange facing inwards. Maximum pressure valve to prevent machine overload. Thermal overload protection for both electric motors. Main switch, emergency stop switch, 24 V transformer, equipment according to UVV standards. Multi-button switch mounted on the swivel arm for operating the machine. A set of keys and tools including operating manual in German. In practice, it has been shown that the quality of bending angle steel with the existing standard roller sets leads to limited results. Gbodpfjz Nhlijx Aa Esw Extensive investment! In recent years, important core components of the hydraulic system have been professionally renewed. The execution of the work is fully documented with existing invoices: • 2021: All hydraulic hoses were completely replaced. • 2022: As part of an oil leak repair, a brand new Bauer hydraulic motor was installed. The total cost for the motor including professional installation amounted to approximately €21,000 net. • Proof is available for the hydraulic motor: Test Certificate for Hydraulic Motors, Certificate of Conformity, Manufacture Certificate, and invoices. Sales and delivery conditions: • Pricing: Ex works (net, plus VAT). • Logistics: The dismantling, loading and collection must be organized and carried out by the buyer himself or by a freight forwarder commissioned by him. • Technical specifications according to existing documents. Subject to prior sale.

Condition: new, Year of construction: 2025, Edge grinding machine with an overhead feed mechanism What distinguishes the Uniq-S from the Uniq is the feed system integrated into the machine table, featuring a rubberized feed belt and an overhead pressure bar. This significantly simplifies the grinding and production of bevelled and chamfered edges, as well as the serial grinding of workpieces. Furthermore, it provides assistance when processing exceptionally large or small parts. The feed speed can be continuously adjusted between 3 and 15 m/min. A soft conveyor belt at the bottom and rubberized rollers on the upper pressure bar gently convey the material. An optional second, lower conveyor belt is also available. The upper pressure rollers can also be replaced with a rubber band, which is particularly helpful when grinding extremely small parts. The Uniq-S is recommended as an all-rounder that enables all types of processing – from solid wood to fine veneer edges – with high quality. The continuously adjustable feed speed allows for optimal adaptation to the material. 1. Grinding station: “Veneer side” 2. Grinding station: “Solid wood side” 3.

Condition: new, Year of construction: 2026, The BENDMASTER 50 Mandrel-Free Tube Bender is an industrial machine designed for bending steel tubes and hollow sections without the need for an internal mandrel. Its integrated hydraulic clamping system, two operating modes – automatic and manual – and digital bending angle display ensure exceptional precision, repeatability, and ease of operation. The machine is ideal for mass production, prefabrication of piping systems, and workshops requiring precise control over the bending process. Main Advantages of the CORMAK BENDMASTER 50 Tube Bender Mandrel-free bending – bending tubes and hollow sections without cross-sectional deformation and without the need for an internal mandrel. Hydraulic clamping system – precise clamping force automatically adjusted according to the tube diameter. Two operating modes: automatic and manual – full control over the bending process, with the ability to program bending sequences or operate the machine manually. Digital bending angle readout – real-time display of the preset and actual bending angles on the operator panel. 2.2 kW main motor – ensures stable bending die rotation, even when processing large-diameter tubes. Gbjdpsvugw Hefx Aa Eew Bending dies for tube diameters of 25, 32, 38, and 48.3 mm – ready for operation with the most commonly used steel tube sizes. Bending angle up to 180° – enables the production of full bends and closed-shape components. Construction and Technology The BENDMASTER 50 is equipped with two independent motors: a 2.2 kW main motor driving the gearbox and bending die, and a 1.1 kW motor powering the hydraulic pump responsible for the clamping system. In programmed mode, clamping is performed automatically using an adjustable limit switch. This configuration allows optimal clamping parameters to be achieved for each tube diameter, improving bending quality and repeatability. The control panel features a clear digital display showing both the preset and actual bending angles. Precision and Operating Efficiency The BENDMASTER 50 tube and profile bender offers a full bending range of up to 180° while maintaining high accuracy. The bending die rotation speed of 5 rpm provides precise control over the shape of the workpiece while maintaining high productivity. Automatic mode enables repetitive bending in mass production with minimal operator involvement, while manual mode offers maximum flexibility and allows settings to be adapted to specific workpiece requirements. The machine is ideally suited for bending medium- and large-diameter steel tubes in serial production environments. Applications The BENDMASTER 50 mandrel-free tube bender is suitable for a wide range of industries and applications, including: Manufacturing piping systems for plumbing, heating, and industrial installations. Prefabrication of balustrades, handrails, and structural frames. Production of furniture components and decorative elements made from steel tubes. Standard Equipment Digital bending angle readout.
