    Centerless through-feed grinding
    Centerless through-feed grinding is a machining process that offers significant advantages over traditional grinding methods. It eliminates the need for clamping or centering the workpiece, allowing for the efficient processing of bar material and thick-walled tubes. This method supports workpieces across the entire width of the grinding wheel, enabling the grinding of very small diameters with higher roundness accuracy. The process is highly automated, resulting in higher speeds and productivity with minimal idle times, making it an efficient and precise grinding method. The RSM 60 modernization project focuses on upgrading and overhauling grinding machines to improve their performance and reliability. This initiative includes refurbishing ten RSM 60 units at the Mönchengladbach service workshop from 2023 to 2027, with plans to reactivate two additional machines. Key improvements involve removing hydraulic components for easier maintenance and integrating pre-assembled modules with Siemens motors. These upgrades have been successfully implemented in several machines, with a complete overhaul scheduled for 2025-2026. 

    HMI Visualization and PLC Siemens S7-TIA
    The Siemens S7-TIA PLC (Totally Integrated Automation Portal) is a state-of-the-art control system integrated into grinding machines to enhance their functionality and efficiency. It provides advanced automation capabilities, including precise control, improved visualization, and seamless integration of hardware and software components. By modernizing grinding machines with Siemens S7-TIA, operators benefit from reduced downtime, optimized processes, and enhanced reliability, ensuring the machines perform at their best.

  • Services for copper tube drawing

    Modernizations & Upgrades

    ProConTube
    A prime example of our innovative thinking is the ProConTube system, which substantially reduces copper tube eccentricity. Wherever it is installed – as part of a complete new production line or in an existing copper tube manufacturing process – you benefit substantially. That’s because every decrease in copper tube eccentricity translates into high material savings and improved cost effectiveness. ProConTube is an independent machine unit positioned directly upstream of the drawing unit.
    ProConTube is based on special sensor technology integrated into the die. This continuously calculates the wall thickness distribution over the circumference of the tube as it passes through the machine. The control system immediately processes the data, then a mechanical unit upstream of the copper tube drawing unit regulates the entry of the material into the die. Plus, there is an ultra-dynamic hydraulic system that ensures fast, precise swivel motions.

    Electrohydraulic Jaw Control
    This service involves replacing maintenance-intensive plungers with a mechanical control block, specifically designed for copper tube production. For sensitive dimensions in copper tube manufacturing, the timing can be individually adjusted on the HMI. This adjustment significantly reduces maintenance needs and improves production efficiency in copper tube facilities.

    Critical major spare parts
    We recommend having ready-to-install assemblies for the core equipment in copper tube manufacturing. Typical examples include a complete main shaft with pre-assembled and aligned cams specifically designed for copper tube production. Another example is a fully assembled spare drawing carriage tailored for copper processing. Quick repairs significantly reduce unexpected production downtime in copper tube lines. SMS group can provide comprehensive lists for all copper tube production lines, detailing recommended parts and assemblies.
