From CAD to Part: The Process

Stone CNC Production Workflow: From CAD to Finished Part

At Shenzhen Honyo Prototype, our stone CNC machining process integrates advanced digital tools with deep material science expertise to transform client CAD models into precise, high-quality stone components. This structured workflow ensures efficiency, minimizes risk, and guarantees exceptional results for challenging stone materials like granite, marble, and engineered quartz. The process rigorously follows three critical phases: AI-Powered Quoting, Expert Design for Manufacturability (DFM) Review, and Precision Production.

The workflow initiates with our proprietary AI Quote Engine. Upon receiving a client’s 3D CAD model (STEP, IGES, or native formats preferred), the system performs rapid geometric analysis. It automatically calculates material volume, identifies complex features requiring specialized toolpaths, and estimates machine runtime based on historical data for specific stone types. Crucially, the AI factors in stone-specific variables such as material density, inherent brittleness, and typical tool wear rates. This generates a highly accurate preliminary quote and lead time within hours, providing immediate transparency on cost drivers like material waste potential and secondary operations.

Following client approval, the project enters the mandatory DFM review phase led by our senior stone machining engineers. This is not an automated step; it requires deep material-specific insight. Engineers meticulously analyze the CAD model for stone’s unique constraints: grain direction sensitivity, minimum wall thickness limitations to prevent breakage, optimal part orientation to minimize internal stresses during cutting, and feasibility of intricate details without chipping. We proactively identify potential issues like undercuts requiring specialized tooling or features prone to edge chipping and collaborate directly with the client to suggest robust, manufacturable design refinements. Physical sample verification of the specific stone batch is often recommended at this stage due to natural material variation.

Only after DFM sign-off does production commence on our specialized stone CNC platforms. We utilize high-torque, low-vibration machines equipped exclusively with diamond-coated tooling (sintered or brazed) capable of machining abrasive stone. Parameters are meticulously dialed in based on the confirmed stone type and DFM insights. Critical machining parameters are strictly controlled as shown below:

| Parameter | Typical Range for Stone | Critical Consideration |

| :—————– | :———————- | :—————————————– |

| Spindle Speed | 500 – 2,000 RPM | Low speed prevents heat buildup & chipping |

| Feed Rate | 100 – 500 mm/min | Slow, consistent feed minimizes fracture |

| Depth of Cut | 0.5 – 2.0 mm | Shallow cuts reduce tool load & vibration |

| Coolant/Lubrication| Non-corrosive Mist | Controls dust, cools tool, prevents staining |

Machining occurs in multiple controlled stages: roughing to remove bulk material, semi-finishing for accuracy, and fine finishing for critical surfaces. Post-machining, parts undergo thorough cleaning, meticulous deburring using stone-specific techniques, dimensional verification against the original CAD, and optional surface treatments like sealing as specified. This integrated, stone-centric workflow ensures Honyo delivers dimensionally accurate, structurally sound prototypes and low-volume production parts with minimal rework, leveraging technology where it adds value while relying on irreplaceable human expertise for material mastery.
