Large-Bed CNC Machining Guide: 3,500 mm Vertical Milling & Subcontracting Tolerances
Contract large-bed machining on a 3,500 mm vertical machining centre: tolerances and capacity for die plates, frames and large parts.

Large-Bed CNC Machining: Precision Engineering in Heavy Industry
In industrial machinery, press frames, rolling mills and large stamping die sets, one of the most critical challenges is machining oversized components with micron-level tolerances. When part dimensions reach several meters and weights exceed tons, standard machine shops lack both the bed travel and rigidity required.
At OSEL Makine, located in KOBI OSB (Dilovasi / Kocaeli, Turkey), our 2,000 m² facility is equipped with a 3,500 mm vertical machining center and a 40-ton overhead crane, delivering turnkey subcontracting solutions for demanding heavy engineering projects.
Key Capabilities:
- Bed travel up to 3,500 mm with high static rigidity.
- Machining tolerances down to ±0.002 mm.
- In-house 40-ton crane for safe part positioning.
- Stamping die bolster plates, heavy bearing housings and welded chassis surface milling.
