About LWS – Precision from Feuchtwangen
LWS GmbH (Lechner Werkzeug Service), based in Feuchtwangen, has been manufacturing superhard cutting tools and cutting inserts made of polycrystalline diamond (PCD), cubic crystalline boron nitride (CBN), carbide, CVD diamond, ceramics and HSS for over 30 years. The range of services includes cutting inserts, rotary tools such as milling and drilling tools made of solid carbide or with brazed PCD, CVD and CBN cutting edges, hard-material wear parts (cutting and punching knives, slide rails, stops, measuring probes) as well as mould making and development. The manufacturing processes include CNC machining, contract vacuum brazing in the company's own high-vacuum furnace, and since 2020 a laser system for cutting edge preparation, laser-inserted chip breakers and chip guide steps. An in-house HighLife Tool Service handles reconditioning and regrinding to extend tool life and improve tool economics. The tools are used mainly in the aviation, automotive and mechanical engineering industries. The company is certified to DIN EN ISO 9001 and was featured in the magazine Werkzeug-Technik in 2024.

Cutting Materials & Processes
Polycrystalline Diamond
Extremely hard, wear-resistant cutting material made of sintered diamond particles for high-performance machining.
Cubic Crystalline Boron Nitride
Second-hardest known material for extremely wear-resistant tools for machining hard materials.
Carbide
High wear resistance and hot hardness, can be tailored to the specific application and is economical with coatings.
CVD Diamond
Binder-free diamond cutting material offering clear advantages over PCD in highly abrasive applications; manufactured by vacuum brazing onto a carbide base carrier.
Ceramic Cutting Material
Lightweight, very hard cutting material for cast iron and hard cast steel, usable without coolant and often regrindable.
High-Speed Steel
Material for cutting knives and wear parts such as punching and cutting knives.
Cast Iron & Cast Steel
Typical materials machined with ceramic cutting inserts in grooving, face turning and milling processes.
