FAQ (Frequently asked questions)

Profile bending machines are used to precisely bend metal profiles — such as steel, stainless steel or aluminium — with maximum repeat accuracy and efficiency. This includes not only achieving the required radius but also maintaining the shape stability of the profile cross‑section and producing clean transitions without deformation.

PBT’s CNC‑controlled profile bending machines feature open interfaces and can be integrated with a wide range of systems. Whether partially or fully automated, PBT enables flexible, efficient and future‑proof bending solutions.

With more than 35 years of experience, PBT develops CNC profile bending machines known for exceptional precision, reliability and energy efficiency.
Customers can choose between manual, NC or fully digital control systems, all designed for reproducible, economical bending processes.

  • ARKUS12®: Compact, ideal for small steel or aluminum profiles in tight spaces.

  • PBT15®: Latest model, available with 40 mm or 65 mm shafts, versatile and space-saving.

  • PBT25®: Modular design, quick tool changes, three individually driven shafts, suitable for profiles up to 300 mm high.

  • PBT35 Servo Wide®: Servo-driven, high torque reserves, wide range of applications.

  • HELIX Servo®: Designed for extra-large profiles, with up to 65 t of X-axis force.

PBT machines are suitable for a wide range of materials, including:

  • Aluminium

  • Stainless steel

  • Structural steel

  • Brass and copper

  • Special lightweight or construction profiles

  • Thin‑walled decorative or sensitive profiles

With custom‑made tools, even complex geometries can be processed safely and accurately.

Yes. PBT designs and produces custom bending tools precisely matched to the profile geometry, material, wall thickness and required bending radius.

PBT supports customers early in the profile design phase, providing recommendations to improve bendability and reduce deformation.
In addition, PBT offers test bending in its facility to validate feasibility, determine optimal tool design and ensure maximum process reliability — before purchasing a machine.

Depending on the machine model, four control options are available:

All systems run on Windows 10, featuring graphical program visualization and intuitive, fast programming.

Yes. All PBT machines can be integrated into partially or fully automated production lines.
Automation options include:

  • Automatic loading and unloading systems

  • Robotic handling solutions

  • Inline measurement systems

  • Digital interfaces to ERP/MES

  • Custom automation concepts

This allows production processes to be efficient, consistent and future‑proof.

The right choice depends on:

  • Profile size and geometry

  • Material (e.g. aluminium, steel, stainless steel)

  • Required bending radius

  • Production volume (one‑offs, small series, large series)

  • Desired automation level

PBT offers free consultation and test bending to determine the ideal machine and tool configuration.

Yes. The service portfolio includes:

  • Installation & commissioning

  • Operator training

  • Maintenance & inspections

  • Fast spare parts supply

  • Remote support

  • Retrofit services for older machines

This ensures PBT machines remain accurate and productive over many years.

Delivery times depend on the machine model, configuration and current production capacity.
PBT provides transparent delivery information and can offer priority delivery or interim solutions if required.

Yes. All PBT profile bending machines are compatible with a mandrel bending device.
PBT offers various sizes and designs—from manual units to fully CNC‑controlled mandrel feeds.

Custom mandrel tools are manufactured to match the specific profile geometry and material.
A precise mandrel feed allows very tight radii, typically down to 2.5 × the profile width.

Automatic feed and optional lubrication ensure accurate, repeatable and gentle bending results.
