Five-Axis CNC Machining Centre
Complex elements are where stone projects most often go wrong: the drawing is buildable on paper but will not assemble on site. Hengsheng runs the Italian Breton NC260 five-axis CNC centre, linking 3D modelling through to finished machining in one automated flow with accuracy to 0.1mm. Measured against previous practice, complex-work accuracy improves significantly and site rework falls noticeably.
Core Strengths
- Micron-level accuracy: five-axis motion under full computer numerical control holds error to 0.1mm, so lines and curves of complex elements follow the model.
- Automated from model to part: programs are generated straight from the 3D model with path simulation, cutting manual setting-out and trial work, and shortening drawing-to-part time.
- Complex and curved work together: complex cutting, carving and curved surface machining run on one machine, suited to shaped columns, sculptures and facade elements.
- Quantified client value: complex-work accuracy improves significantly, on-site grinding and adjustment time falls, and rework and waste fall with it.

Service Process
- Model received: the design 3D model is taken, or built from 2D drawings with sections added.
- Machinability review: internal corner radii, minimum tool radius and fixturing checked for feasibility.
- Path simulation: tool paths generated and simulated to rule out interference and overcutting.
- CNC machining: formed in one set-up on five axes with coolant throughout.
- Dimensional check: key dimensions verified to model, numbered and shipped with an assembly drawing.
Applications
- Shaped elements driven by a three-dimensional model
- Workpieces finished on several faces in one setup
- Prefabricated elements demanding tight tolerances
- Standard shaped parts that must be repeated
Sustainability & Certification
One-pass forming removes re-fixturing and rework, cutting material and power use; coolant and cooling water join the 95% plant recycling loop, with slurry collected for reuse.
CNC machining raises yield and offcuts return to mosaic and aggregate at over 85% utilisation; standby sleep and variable-frequency drives lower unit energy consumption.
Deep Selection Guide
Whether a complex element is buildable depends on whether the fabrication method was considered at design stage: internal corners too tight, curve radii too small or insufficient clamping area all make a drawing unbuildable. Bring the fabricator in at concept stage with a 3D model or complete sections, and approve a physical sample before volume production to confirm line and joint. Where elements assemble on site, insist on factory dry-assembly numbering and an assembly drawing — installing by number saves a great deal of grinding time.
- Selection criteria：When choosing stone for Shaped elements driven by a three-dimensional model, ask first whether Micron-level accuracy holds, then look at colour and veining - reverse the order and the work usually has to be redone.
- Specification & thickness：Set size by Machining accuracy (≤0.1mm) and thickness according to Workpieces finished on several faces in one setup; junction and cut-out positions must be clear on the drawing so no second machining is needed on site.
- Acceptance & records：Automated from model to part: programs are generated straight from the 3D model with path simulation, cutting manual setting-out and trial work, and shortening drawing-to-part time. is a mandatory pre-dispatch check, with results and images archived; accept on site by number, and batch records can be retrieved if a dispute arises.
- Sustainability：One-pass forming removes re-fixturing and rework, cutting material and power use; coolant and cooling water join the 95% plant recycling loop, with slurry collected for reuse. Fold this into the acceptance documents and check it against the green material rules that apply locally.
Hengsheng approaches Five-Axis CNC Machining Centre by putting quarry, fabrication, testing and delivery on one traceable chain, so the client receives evidence on programme, quality and compliance, not merely a consignment of stone.
FAQ
- Why do complex elements go wrong so often?
- They are affected at three ends at once: the design's internal corners and curves may not be machinable, dimensional error in fabrication is magnified at assembly, and installation lacks a positioning datum. Programming from a 3D model, simulating tool paths and dry-assembling with numbering in the factory control those three errors separately.
- How does five-axis CNC improve complex-work accuracy?
- It comes from comparison before and after introducing the five-axis CNC flow. Previously, with manual setting-out and repeated re-fixturing, a high proportion of elements needed grinding and adjustment on site; after moving to model-driven machining with pre-assembly numbering, that proportion fell sharply.
