Bihler LEANTOOL Technology

Standardized Tooling System

With the LEANTOOL system you now implement new radial and linear forming tools easier, faster and cheaper. The perfect consistency of the standardized tooling kit – from planning to design, manufacturing to production – reduces the realization times and manufacturing costs of your new tools by up to 70 percent.

At the same time, you benefit from very fast “time-to-market” for your new stamped and formed parts and assemblies. As tailor-made platforms for the radial and linear LEANTOOL forming tools, the RM-NC and GRM-NC servo machines and the BIMERIC servo production and assembly system guarantee a flexible and efficient production.


Benefit from these advantages:

  • Very fast “Time to Market” for classic stamped and formed parts, wire parts as well as more complex progressive components
  • Quick feasibility statements and precise quotations
  • Simple and structured design methodology of bNX Software (design support with applications and templates)
  • Very short tool production times (up to 70 % standard machine and tool parts)
  • Up to 70% lower manufacturing costs compared to conventional forming tools
  • Extremely fast, 100% reproducible setup operations (automatic slide positioning, quick clamping systems, data retrieval from VC 1 control system)
  • Significant material savings, especially with the LEANTOOL Radial (strip width equal to part width)
  • Lower logistics and maintenance costs

Implementing new tools according to the radial principle

Highlights at a glance

  • Up to 70% standard tools regardless of task
  • Up to 70% lower manufacturing costs compared to conventional radial tools
  • Significant material savings due to part width equal to strip width
    Consistently high product quality due to bending in the ideal grain direction
  • Optimum bending angle infinitely adjustable

LEANTOOL Radial is an intelligent optimization of the existing Bihler radial principle. Thanks to the innovative features of the (G)RM-NC servo machines and the servo-controlled bending units, the number of parts in a LEANTOOL radial tool can be reduced to a minimum. The tool parts also consist of 70% standard parts, and do not have to be reworked or only have to be reworked slightly.

Implementing new tools according to the linear, progressive and progressive component principle

Highlights at a glance:

  • Up to 70% standard tools regardless of task
  • Up to 50% lower manufacturing costs compared to conventional progressive tools
  • Simpler tool technology, since tool movements from 3 sides are performed by the machine by default
  • No strip lifting in the tool
  • Less material waste compared to conventional progressive tool solutions

LEANTOOL Linear combines the strengths of traditional progressive tool technology with the strengths of Bihler machine technology. The tools consist of a large number of standardized tool parts made of standard parts and blanks. The machine allows individually controllable movements that can be implemented from above, from below and from the side. All this reduces the overall effort and complexity in the tool and guarantees simplicity, speed and safety.


In close cooperation with Meusburger, Bihler has developed standardized stamping and forming frames with Meusburger standard parts for Bihler NC presses. The new frames “tunnel cut” and “spring-loaded guide plate” are available for NC presses with forces up to 400 kN. The standard stamping and forming frames are significantly more cost-effective, and they are also directly available from stock.

Quickly and Easily

Producers of stamped and formed parts already using a Bihler NC press can obtain the exclusive stamping and forming frames quickly and easily from Meusburger. If you are considering the purchase of a new Bihler servo stamping and forming machine RM-NC or GRM-NC including tool, you will receive an overall offer from Bihler consisting of the NC stamping and forming machine including the suitable standard stamping and forming frame from Meusburger.
