Company
Lerchenmüller-Systeme GmbH is a family-owned company based in Bernbeuren (Upper Bavaria) that has been in the market since 1990 and has its roots in grinding technology. The company processes wear-resistant materials such as tungsten carbide, ceramics, tungsten, molybdenum and heavy metals into customer-specific semi-finished products, blanks and precision parts. Its range of processes includes cut-off grinding, polish grinding, end machining, peel grinding, universal grinding, centerless grinding, profile grinding as well as straightening. Core customers are the cutting tool industry, for which stepped blanks, carbide rods and finished components are manufactured. In addition to series production of lot sizes from 1 to 1,000,000, the company develops samples and prototypes and supports customers in product development. Production takes place entirely in-house on CNC grinding machines with automation; air-conditioned production and measuring areas ensure precision. The quality management system is certified to ISO 9001:2015.
