RS TEC GmbH

What RS TEC GmbH does

RS TEC Spindeltechnologie GmbH is a privately held, ISO 9001 certified spindle technology service and manufacturing company headquartered in Neuweiler, Baden-Württemberg, Germany. Founded in January 2011 by Manasse Röll, the company operates as a manufacturer-independent specialist serving industrial CNC machine operators and machine tool manufacturers across Germany and internationally. Its core technology encompasses spindle design, manufacturing, repair, and testing, supported by in-house spindle test benches, HOFMANN UHK 12.1 dynamic balancing equipment, and a ZEISS Contura G2 coordinate measuring machine for quality inspection.

The company generates revenue across multiple streams: new custom spindle manufacturing (single-piece production with runout accuracy below 2 µm, motor power 6-50 kW, speeds up to 75,000 rpm), spindle repair and overhaul services (with a 6-month or 3,500 operating hours guarantee), spindle exchange hardware sales, preventive maintenance contracts, dynamic balancing services per DIN ISO 1940, CNC machine repair and maintenance, electric motor service, precision parts manufacturing, clamping fixture production, Cobot-based manufacturing automation integration, and machine transport and company relocation services. Pricing is quote-based, with typical repair tiers ranging from approximately €2,000 for bearing replacement to approximately €7,000 for complete overhauls, and a 40-70% cost advantage versus new spindle purchase.

The company employs a sales-led, direct B2B go-to-market model with field sales representation, structured consultation/quote/brochure request forms, and a content marketing strategy through its website blog and LinkedIn presence. Customers include German precision manufacturers such as C. Josef Lamy GmbH, Zerspantech, and G.u.K. Ihle e.K. Strategic partnerships include HSTec for spindle unit design, BIG DAISHOWA SEIKI for BIG PLUS® spindle system certification, and MATRANS for factory relocation services. The firm is founder-owned with a five-person team and actively hiring additional mechatronics engineers.

Direct peers

• HSD S.p.A. Italian manufacturer of electrospindles, milling and high-speed spindles for CNC machines, with global service support — a comparable high-frequency spindle manufacturer competing for the same European machine tool builders.
• Setco (Setco Precision Spindles): US-headquartered spindle manufacturer and repair specialist offering high-speed precision spindles and remanufacturing services, mirroring RS TEC's combined manufacture-plus-repair model for CNC machine tools.
• GMN Paul Müller Industrie GmbH & Co. KG: Germany-based precision spindle manufacturer (high-frequency, motor, milling and grinding spindles) that competes directly with RS TEC in custom spindle design, manufacturing, and service across CNC machine tool builders.
• Weiss Spindeltechnologie GmbH: Germany-based spindle specialist combining new spindle manufacturing with repair services and covers the same manufacturer-independent niche CNC operator customer base as RS TEC.

Broad incumbents

• NSK Ltd. (Spindle & Machine Tool Bearings): Global bearings manufacturer that also produces precision spindle units and offers spindle remanufacturing/services for machine tools, operating at much larger scale than RS TEC across the same end-application.
• SKF (Spindle & Precision Bearings): Large bearings and rotating equipment supplier whose spindle bearing and remanufacturing capability overlaps with RS TEC's repair and precision balancing services at industrial scale.
• Siemens Industry (Machine Tool Business): OEM of CNC controls, SINUMERIK, and main spindle motors referenced by RS TEC (SIEMENS motor service is part of its portfolio); represents the OEM service network against which independent repairers like RS TEC position themselves.

Others

• Hoffmann Maschinen- und Apparatebau GmbH: Manufacturer of dynamic balancing machines (the HOFMANN UHK 12.1 unit used by RS TEC for in-house and on-site balancing); adjacent ecosystem supplier for spindle balancing services rather than a spindle competitor.
