Headquartered at Hollého 201/48 in Rajec, Slovakia, JDK-tech s.r.o. is a professional mechanical engineering and CNC subcontracting company focused on advanced metal machining. Our workshop is equipped with modern CNC turning, 3-axis and 5-axis milling, grinding and EDM machines for complex custom part production.
We hold ISO 9001 and ISO 14001 quality and environmental management certifications. Every batch goes through input, in-process and final inspection, with measurement protocols, material test certificates and surface treatment documentation provided to customers.
Our customers come from Slovakia, Czech Republic, Austria, Germany and other EU countries. We work closely with machine builders, automation integrators, energy equipment manufacturers and engineering offices, delivering single prototypes, small batches and serial production runs according to technical drawings and STEP / IGES CAD files.
Large diameter & long workpieces
Complex shaped components
High surface finish
Heat & coating services
From prototype development, CAD drawing review, CNC programming, production, metrology inspection to final surface treatment and packaging, we provide a full turnkey subcontracting service for mechanical parts.
Precision CNC lathe work including large diameter turning up to 1090 mm and turning length up to 4000 mm. Suitable for shafts, rollers, flanges and rotational components from steel, aluminium, brass and stainless steel.
Advanced milling with 5-axis simultaneous machining for complex geometry, mould inserts, fixture parts and custom mechanical assemblies. Working envelope up to X:3000mm, Y:850mm, Z:800mm for large workpieces.
Rotary and surface grinding for tight tolerance and low roughness requirements. Ideal for functional contact surfaces, bearing seats and parts where smooth surface quality is critical for wear resistance.
Electroerosive cutting and sinking for hardened steel, thin slots and intricate internal profiles that cannot be easily achieved with conventional milling tools. Maximum working area 600×400 mm.
We coordinate certified subcontract partners for heat treatment, hardening, anodizing, galvanizing, powder coating and other surface treatments. All processes come with test certificates and material attestations.
3D coordinate measurement, roughness testing and dimensional inspection. Every delivered order includes measurement reports, material certificates and inspection logs to support your internal quality and audit requirements.
Our production follows STN EN ISO 9001 quality system. Process control, operator training, machine calibration and continuous improvement are embedded in all manufacturing workflows.
We maintain an environmental management system to reduce waste, optimise material usage and manage cutting fluids, packaging and industrial waste according to Slovak and EU environmental regulations.
Material test reports, 3D measurement protocols, coating and heat treatment attestations are supplied with each shipment, fully traceable back to production batches and raw material lots.
We deliver prototype parts, small custom runs and serial production for machine builders, automation, energy and transport equipment across Central Europe.
