What STOPP does

STOPP Werkzeugmaschinen GmbH is a German family-owned CNC machine tool manufacturer headquartered in Weinheim, founded in 1938 and currently operating under third-generation leadership of Managing Director Dipl.-Ing. Bernd Stopp (since 2011). The company employs 11-50 people and operates as a system provider rather than a standalone machine vendor, combining CNC turning machines, automation cells, production metrology, and special machines into turnkey production cells delivered to industrial manufacturing customers.

The product portfolio spans horizontal and vertical CNC turning machines (AUTOturn, STOPPturn 300/400, LS3100, VDR, PU3100), multi-spindle configurations (LDS3100 Linear Double Spindler, LT3100 Linear Transfer), and a comprehensive automation stack including 6-axis articulated arm robots, SCARA robots, pallet magazines, portal loading, and blister packaging modules. A manufacturing metrology line covers 100% in-process inspection, dynamic run-out measurement, mobile measurement cells, and Q-das-compatible data feedback. STOPP also builds special machines—rotary indexing tables, superfinishing machines, roller burnishing cells, and custom projects—using a modular building block system. Products integrate with third-party platforms including FANUC robots (under FANUC System Partner status), Siemens 828D CNC controls, Renishaw Equator gauging, Tesa probes, Studer and Liebherr grinding machines, and Profinet-based industrial networking. The proprietary Linear Spindle (LS3100) architecture, where the spindle stock moves in both axes for very short gripping distances, and dual-spindle (LDS3100) parallel-machining configurations represent STOPP's core mechanical differentiators.

STOPP sells direct to industrial manufacturing customers via consultative enterprise field sales, with custom-configured systems and project-based pricing that is not publicly disclosed. Customers are primarily German precision component manufacturers seeking turnkey automated turning and quality-control solutions. Distribution is direct with no dealer network or e-commerce channel; geographic footprint is concentrated in Germany with no disclosed international operations or subsidiaries. Revenue is not publicly disclosed.
