Condition: repair required (used), Year of construction: 2010, operating hours: 7,700 h, functionality: not functional, machine/vehicle number: 15158-10, working range: 4,000 mm, sheet thickness (max.): 12 mm, sheet thickness steel (max.): 12 mm, CNC plasma cutting system BACH ThermoCut 2000 with pipe cutting device, TEKA dust extraction system, and plasma source. Manufacturer: BACH Maschinenfabrik GmbH Type: ThermoCut 2000 Year of construction: 2010 For sale is a used CNC plasma cutting system BACH ThermoCut 2000, including pipe cutting device, plasma source, dust extraction system, and complete piping. The system was used in our machine manufacturing company until recently and is suitable for cutting sheet metal as well as processing pipes. Technical data: Working area: 4,000 x 2,000 mm Plasma source: Thermal Dynamics Ultra-Cut 100 CNC control: myBach Pipe cutting device included Pipe diameter: min. 50 mm max. 320 mm Max. cutting thickness: Mild steel: up to 12 mm Stainless steel: up to 10 mm TEKA filter and dust extraction system included Complete dust extraction piping system included CE marking available Maintenance and condition The system was regularly maintained during its entire service life. Official maintenance by the manufacturer was last performed on August 20, 2013. After that, ongoing maintenance was carried out in-house. Filters of the TEKA dust extraction system were renewed approximately 6 months ago. Cutting torch head was renewed approximately 4 years ago. Cooling water filter is changed regularly, approximately once a year. The operating hour counter of the dust extraction system currently shows approximately 7,700 hours. Since the system was operated exclusively with the dust extraction system running, this value can be used as a good indication of the total operating time of the system. Known defect The system is currently not operational. After consultation with Voortman and Mr. Sobiech from Magma Industries, the cause is likely to be in the cooling circuit of the plasma source. According to the experts, the most likely causes of the fault are: Defective cooling water pump Defective flow sensor Leakage on the suction side of the cooling water system A final fault diagnosis has not yet been carried out. Spare parts for the installed Thermal-Dynamics plasma source are now only available to a limited extent. The machine is therefore explicitly sold as a system requiring repair or for refurbishment.

Condition: new, Year of construction: 2025, operating hours: 30 h, Panel benders (also known as swing bending machines or folding machines for sheet metal) are used across various industries where precise, automated bending of sheet metal components is required. The main sectors include: 🏭 Metalworking & Sheet Metal Processing Contract manufacturers / Sheet metal processing companies Series and single-part production Enclosures, housings, cassettes, boxes 🚗 Automotive Industry & Suppliers Structural and body components Brackets, covers, interior components Especially suited for mass production requiring consistent repeatability ⚡ Electrical Engineering & Electronics Njdpfx Abeyb Hu Nszowi Switchgear and distributor manufacturing Enclosures for controls, servers, industrial electronics Very common use due to numerous 90° bends and complex contours ❄️ Household Appliances & White Goods Washing machines, refrigerators, ovens Internal frames, covers, claddings 🏗️ Construction Industry & Architecture Facade elements Roof and wall claddings Metal panels, cassettes 🚆 Transport & Public Transit Rail vehicles, buses, commercial vehicles Interior claddings, technical housings 🛠️ Mechanical & Plant Engineering Machine frames Protective claddings Switchgear enclosures 🌬️ HVAC / Air Conditioning Technology Ventilation ducts HVAC unit enclosures Air distribution systems 🏥 Medical Technology Equipment enclosures Stainless steel claddings High requirements for precision & surface finish Why Panel Benders in these sectors? ✔ High degree of automation ✔ Excellent repeat accuracy ✔ Ideal for complex bent parts ✔ Gentle processing of painted or coated sheets ✔ Fast processing for small to medium batch sizes

Condition: new, Year of construction: 2025, functionality: fully functional, operating hours: 30 h, ✅ 1. Metalworking companies with medium to high volumes 🔹 Series production / repeat parts If you produce many identical or similar parts, automation pays off as it reduces the cost per part and ensures consistent quality. 🔹 High production > 1,000 parts/month The higher the output, the faster the investment pays for itself through increased productivity. ✅ 2. Companies facing skilled labor shortages or high workloads 🔹 Difficulty finding or retaining qualified staff A robot can partially replace skilled operators and safeguard production capacity. Nsdpoyb I Azjfx Abzswi 🔹 Night shifts / 24/5 production Robots can work longer and without fatigue → higher output without additional personnel. ✅ 3. Companies with complex bending processes or high quality requirements 🔹 Tight tolerances / minimizing errors A robot ensures consistent repeatability. 🔹 Complex downstream processes (e.g. handling, deburring, stacking) An integrated robot can take over tasks that would otherwise be performed manually. ✅ 4. Manufacturers facing tight deadlines or cost pressure Short delivery times required Automation reduces throughput times. 🔹 Cost pressure due to competition Longer machine utilization and lower unit costs improve competitiveness. ✅ 5. Future-oriented companies 🔹 Industry 4.0 / digitalization An automated press brake can often be integrated more effectively into IT/MES systems. 🔹 Scalable production If you plan to grow in the future, you have a flexible foundation.
