Precision Machining & Deep Hole Drilling
Zonap specializes in machining complex and critical components with tight tolerances and excellent surface finish. Our infrastructure includes CNC turning, VMC, HMC, multi-axis machining centers, and advanced deep hole drilling systems. We routinely manufacture parts with challenging geometries, long bores, and multi-operation features in a single setup.
Tight Tolerance Capability
- Dimensional tolerance up to ±0.005 mm on critical features
- Bore straightness up to 0.02 mm per meter in deep hole drilling
- Roundness and cylindricity within 0.01 mm
- Surface finish up to Ra 0.4 µm on precision components
- Parallelism and perpendicularity within 0.01 mm
- Repeatability maintained across batch production
Heavy Fabrication & Structural Manufacturing
Zonap manufactures heavy and complex fabricated structures including machine frames, skids, and welded sub-assemblies. Fabricated parts are stress relieved and machined after welding to ensure dimensional stability and accuracy.
Metallurgical & Special Processes
- Heat treatment: annealing, normalizing, quenching, tempering, stress relieving
- Shot blasting and surface preparation
- Industrial painting and coating
- Plating and corrosion protection
- Wear-resistant and surface enhancement treatments
Assembly & Sub-System Integration
Beyond part manufacturing, Zonap delivers complete sub-assemblies and mechanical systems—reducing customer assembly time and simplifying supply chains with ready-to-install solutions.
