Precision Medium Parts

Hundreds of CNC Centers. Zero Defects.

Medium Part & High-Volume CNC Machining

While Openex commands global recognition for machining colossal 250-ton megastructures, heavy equipment also requires thousands of precisely manufactured internal components. To meet this demand natively, we operate a dedicated fleet of hundreds of high-speed Horizontal (HMC) and Vertical (VMC) CNC Machining Centers, and multi-axis turning lathes.

Whether your project requires complex fluid valve bodies, multi-stepped aerospace shafts, or medium-scale hydraulic cylinder components, our facilities provide sub-micron precision and unmatched batch consistency. By combining heavy structure fabrication and high-volume precision parts machining under one roof, we eliminate your need to manage multiple disconnected supply chains.

Our Precision Machining Fleet

High speed horizontal machining center (HMC)

Horizontal & Vertical Machining (HMC / VMC)

Outfitted with advanced automatic tool changers and twin-pallet systems, our CNC milling centers ensure highly efficient production cycles. HMCs allow multi-sided machining with phenomenal rigidity for cutting harder alloys.

  • Typical envelop limits: up to 3,000mm length
  • Ultra-fast rapid traverse reducing cycle time
  • Unmanned night-shift batch capabilities
Precision CNC Turning and Lathe Machining

Precision CNC Turning & Mill-Turn

From high-speed multi-spindle turning to robust mill-turn centers. We deliver perfectly concentric shafts, customized fasteners, spindles, and custom industrial flanges without the need to switch machines, virtually eliminating setup errors.

  • Flawless cylindricity and surface finish
  • Mill-turn axes integration for cross-drilling
  • Tightly integrated QA verification protocols
