Thread Rolling and Gear Cutting Tools for Metalworking

The LMT Tools Group, represented by the LMT Fette brand, took over the sales and customer support for components from the insolvent Adam Rollsysteme GmbH on May 1, 2026. This measure ensures the continuous supply chain of spare parts, rolling heads, and thread rolls for industrial metalworking. In parallel, the company is concluding the one-year integration phase of the machines and skilled workers from PWS Präzisionswerkzeuge GmbH, significantly expanding the internal capabilities for reconditioning gear cutting tools at the Schwarzenbek site.

Component Supply for Thread Rolling Systems
This measure does not involve a legal takeover of Adam Rollsysteme GmbH, but focuses exclusively on the continued hardware supply for the user base. Affected machine operators will in the future source required thread rolls and rolling heads directly from the LMT Fette product portfolio. Through integration into the group's global sales network, users also receive technical support and process-specific application advice directly at the processing machines on site.

Equipment Integration for Gear Cutting Tools
The expansion of the Schwarzenbek site results from the transfer of equipment and industrial expertise from PWS Präzisionswerkzeuge GmbH (previously based in Schmölln) into the structures of LMT Tools. The integration of the associated machines focuses on the quantitative and qualitative expansion of tool reconditioning in the gear cutting tools segment. LMT Tools will present its latest hardware-based tool solutions and manufacturing technologies from September 15 to 19, 2026, at the AMB trade fair in Stuttgart (Hall 3, Booth D20).




Additional Context: This section details technical specifications not included in the original announcement.
In industrial metalworking, thread rolling (cold forming) is a mechanical process for producing external threads. In strict contrast to thread cutting or turning, where material is removed by chip formation and the material grain is severed, thread rolling plastically deforms the material structure using hardened profile rolls. This forming process systematically compresses the material fibers in the thread root. This leads to significantly higher dynamic fatigue strength, superior surface quality, and increased wear resistance of the finished component. Since the process is chipless, material usage is also optimized, and the risk of chip jams in the machine tool's working area is eliminated. In the area of gear cutting tools, such as those now being reconditioned through the PWS integration at the Schwarzenbek site, these are typically high-precision hobs and shaper cutters. After a certain degree of wear, these tools must be reground and recoated to the exact thousandth of a millimeter to maintain the exact geometric profiles (such as involute gears) for transmission components.
