SK machine service

What SK machine service does

SK Maschinen-Service GmbH is a privately held German limited liability company (GmbH) founded in 1984 and headquartered in Tönisvorst, North Rhine-Westphalia, Germany. The company is an owner-managed specialist dealer in the international trade of used metalworking machine tools, operated by Managing Directors Jutta Krins and Valentin Wienert with a headcount in the 11–50 range. It sources equipment primarily from German and Swiss manufacturers for quality reasons and resells it worldwide to manufacturing and industrial buyers, with secondary specialization in the gear manufacturing (Verzahnungsbranche) segment.

The company's core product is a catalog of used machine tools spanning CNC lathes, milling machines, boring machines, radial drilling machines, vertical turning machines, grinding machines, and supporting equipment such as measuring tools, conveyor systems, and accessories, drawn from brands including DMG-GILDEMEISTER, HESSAPP, MEXPOL, SIP, DIXI, KOLB, DÖRRIES, Greif, DECKEL, MAHO, KLINGELNBERG, and PFAUTER. Inventory is presented on a bilingual (German/English) website with machine videos under power. Around the trading activity, SK Maschinen-Service wraps a full-service package: dismantling supervision, loading and packaging, land and sea transport, customs clearance, assembly and commissioning via specialists, electrical/mechanical inspection, machine valuation, complete facility liquidation, and expert consultation in gear technology applications.

Revenue is generated through two streams: transaction margins on purchased and resold machinery (transaction fee model) and professional service fees for the dismantling, logistics, assembly, inspection, valuation, and liquidation services. Distribution is sales-led and inquiry-based: customers contact the company through website forms or directly, with no e-commerce or self-service purchasing. Pricing is fully quote-based with no public price list, billed per transaction. Marketing is concentrated on the website (online stock list, machine videos, newsletter via CleverReach) and on membership in the LAGERMASCHINEN.DE European dealer network for extended inventory reach. The company has no disclosed revenue, no funding rounds, no subsidiaries, no patents, and no AI or proprietary technology components.
