Electromechanical Round Bending Machine Rollmak SM3 SM70-10/1.8


Rollmak SM3 is an electromechanical three-roll round bending machine that combines high-precision technology with the legendary reliability of a cast-iron construction. It is perfectly suited for the precision processing of shaped parts, cylinders, and modular forms. The Rollmak SM3 is a versatile and durable solution for sheet metal bending. Its structural features—including convenient adjustments, conical bending capability, electric drive, and a robust body—make it ideal for craft workshops, vocational training centers, and small-batch production.

Features and Advantages

  • Swivel-out Top Roll: A quick-opening mechanism facilitates the easy and damage-free removal of finished cylindrical workpieces.

  • Wire Grooves: Integrated at the ends of the rolls for forming wire-reinforced edges or intermediate profiles.

  • Manual Adjustment: Precise handwheels for the rear and bottom rolls ensure simple and accurate setup for various material thicknesses.

  • Cone Bending Device: The ability to tilt the rear roll enables the creation of conical shapes.

  • Cast-Iron Construction: The rigid cast frame guarantees long-term durability and vibration-free stability during operation.

  • Pedal Control: A separate foot pedal increases operator convenience and safety.

  • Gear-Driven Electric Drive: Ensures smooth and reliable rotation of the rolls.

Options

  • Hardened Rolls: For processing tougher materials and extending tool life.

  • Digital Position Indicator: A readout for the rear roll to enhance repeatability and accuracy.

  • Motorized Rear Roll Adjustment: Automates the positioning process to reduce setup time.

  • Two-Speed Motor: Provides a choice between high-speed production and a slow, high-precision mode.

  • Variable Speed Control: Offers maximum flexibility across different production scenarios.

  • Extended Shafts & Profile Rolls: Allows for the mounting of specialized rollers to bend specific profile geometries.

  • Custom Voltage: Adaptation to specific regional electrical requirements.
