What koch maschinenbau does

Koch Maschinenbau GmbH & Co. KG is a third-generation, family-owned German precision machining company founded in 1946 and headquartered in Limbach-Oberfrohna. It operates two interconnected business lines. The first is high-precision CNC contract manufacturing of small and medium-sized components (1–10,000 piece runs) using a 5-axis Hermle milling fleet, Gildemeister/Weiler CNC lathes, and one of the few 600mm wire-EDM cutting capabilities in Germany; the shop processes steel, stainless steel, aluminium, copper, plastics, titanium, special alloys, and permanently stocks 1.4429 ESR stainless steel with magnetic permeability ≤1.005 for particle accelerator and scientific-instrument customers. The second line is its own product portfolio of stainless-steel precision clamping chucks — the DBF manual series (DBF34 through DBF160, including the marketed world's smallest spiral chuck DBF34), the PSF100 pneumatic chuck, the DDP100 rotary union, custom special chucks, and adapters compatible with Hirschmann PrisFix, Erowa, and System 3R zero-point clamping systems — sold via direct consultation and an in-house bilingual e-commerce storefront.

The company's go-to-market combines direct enterprise sales for CNC contract manufacturing and custom chucks with self-service e-commerce for standard catalog items. Pricing is list-based in EUR excluding VAT (e.g., PSF100 at €1,980; DDP100 at €980; jaw sets ranging €98–€482; zero-point adapters from €346), with 14-day net payment terms and advance-payment requirements for new or international customers. Standard products are shipped globally via GLS. Customers include high-tech and research institutions, vacuum and semiconductor manufacturers, medical device makers, automotive suppliers, and EDM operations across Europe and internationally. Marketing relies on the bilingual corporate website, the online shop, and trade-channel contacts rather than paid digital acquisition.

The business is led by Managing Partners Sandra Koch (purchasing and management) and Martin Koch (production engineering and the Chucks product line), who took over from Werner Koch in September 2016. The company has run a DIN EN ISO 9001:2015 quality management system since 2000 and operates from a single 1,500 m² site (expanded from 750 m² in 2008) in the Kändler industrial park. No external investors, parent company, or subsidiaries are disclosed.

Core offering

Koch Maschinenbau manufactures high-precision custom components via CNC contract manufacturing (1–10,000 pieces) and produces its own line of stainless-steel precision manual clamping chucks (DBF series), pneumatic chucks (PSF100), rotary unions (DDP100), CF flanges for vacuum applications, special/custom chucks, and clamping accessories. The company serves high-tech industries including metrology, EDM, vacuum/semiconductor, medical technology, and research with tolerances down to ≤0.005 mm repeatability and expertise in specialty low-magnetic-permeability stainless steels.

Product overview

Koch Maschinenbau offers two interconnected product lines: precision CNC manufacturing services and precision stainless steel clamping solutions. The CNC manufacturing division produces custom precision components (1–10,000 pieces) for high-tech industries, including CF flanges for vacuum applications. The clamping solutions division manufactures the DBF series of manual precision chucks (DBF34, DBF55, DBF63, DBF100, DBF140x58, DBF160), the PSF100 pneumatic chuck, the DDP100 rotary union, custom special chucks, and comprehensive accessories including adapters for 3R, Erowa, and Hirschmann zero-point clamping systems. All chucks share stainless steel construction, sub-0.02mm runout accuracy, and compatibility with shared accessories across the product range.

Direct peers

• Schunk: German-headquartered global leader in precision workholding, clamping technology, and gripping systems. Direct comparable to Koch in chucking and workholding for CNC machining, though at vastly larger scale and broader product breadth.
• Hainbuch: German manufacturer of precision chucks, clamping devices, and workpiece clamping systems. Highly comparable to Koch's DBF manual and PSF pneumatic chuck lines in target customers (precision machining and turning shops).
• Röhm (Leitz Group): German workholding specialist producing chucks, clamping fixtures, and drill chucks. Comparable product overlap with Koch's chuck portfolio, especially in precision manual and powered clamping for metrology and machining.
• Kitagawa Europe: Japanese-origin manufacturer of precision chucks and workholding, with strong European operations serving CNC turning and machining centers. Direct competitor to Koch in stainless steel and high-precision chucks.
• EROWA: Swiss precision tooling and workholding specialist known for its zero-point clamping system (PPS/ITS) and EDM tooling. Comparable because Koch produces adapters for Erowa's infrastructure and competes for similar metrology and EDM customers.
• System 3R (Hexagon Manufacturing Intelligence): Swiss-origin workholding and palletizing system now owned by Hexagon. Direct comparable because Koch manufactures 3R-compatible adapters and both serve EDM and high-precision machining customers.
• Lang Technik: German precision workholding manufacturer specializing in zero-point clamping systems, vises, and tombstones. Comparable mid-sized German Mittelstand competitor targeting the same precision CNC and EDM customer base.
• Allmatic-Jakob Spannsysteme: German precision workholding manufacturer producing zero-point clamping systems and chucks. Closely comparable to Koch in product type, customer segment, and Mittelstand positioning.
• Hirschmann Precision (a brand of Pfiffner): Swiss/German precision spindle and rotary union manufacturer. Koch both integrates Hirschmann PrisFix and Hirschmann rotary spindles into its products and partners with them; directly adjacent in metrology and EDM applications.

Broad incumbents

• Alfing Kessler Sondermaschinen: German high-precision machining specialist serving automotive, aerospace, and special machinery with complex CNC manufacturing. Comparable to Koch's CNC contract manufacturing stream as a much larger, broader-incumbent precision machining supplier.
