OPERATIONAL BLUEPRINT

Complete Production Workflow

01

YOUR DESIGN

Submit your digital blueprints. We ingest CAD, DXF, or STL files, executing automated geometric validation against raw stone specifications.

02

CNC PROGRAM

Our engineers compile clean G-code. Toolpath spacing, step-overs, and specialized spindle speeds are calculated to maximize precision and longevity.

03

ACTIVE CARVING

Industrial multi-axis machining executes the carving. Heavy spindle pressure meets continuous water cooling to cut clean profiles into dense stone.

04

DELIVERY

Every product undergoes micro-measurement scans. Finished stone elements are carefully crated in shock-isolated crates for safe site logistics.

ENGINEERING TIMELINE

The 9-Step Precision Carving Process

How we transform raw stone into mathematically flawless architecture through robust tool-path planning, physical calibration, and advanced multi-axis robotics.

Share Your Design

Submit your CAD file format (.dxf, .dwg, or .3dm). Our technical engineering team runs automated geometry checks to guarantee perfect model structural viability before machining.

Stone Selection

We evaluate the stone type (marble veining, density, and physical properties). This ensures that structural properties match your design tolerances and the chosen physical slab.

Tool-Path Planning

Our CAM specialists chart multi-axis paths. We calculate step-overs, tool diameters, feed-rates, and fluid flow direction to guarantee continuous structural safety and machining accuracy.

Workholding Calibration

The massive stone slab is physically locked onto the machine bed. We calibrate coordinate workholding and zero-reference standard points using a digital touch probe system.

Primary Roughing Cycles

Roughing begins. Heavy-duty diamond blades and core drills execute bulk material extraction, removing excess stone volume while continuous coolants prevent thermal cracking.

Semi-Finishing Pass

Using precise medium ball-nose cutters, we step down the carving depths. This cycle smooths aggressive tool stepping and establishes the structural foundation.

Micro-Detail Machining

Sub-millimeter carving using fine diamond burrs. The spindle tracks complex curves and sharp crevices, extracting beautiful details specified by your CAD geometry.

3D Laser Scan Quality Check

We scan the carved piece using digital metrology probes, aligning points back to the CAD design file. Any deviation larger than ±0.05mm is localized and corrected.

Artisanal Hand Polish

Our craftsmen carefully hand-finish complex zones, removing tiny geometric scan marks while respecting mechanical details. Protective technical sealants are applied.

ENGINEERING EXCELLENCE

Why Architects Choose CNC Precision

Absolute Precision

Achieve tight sub-millimeter tolerances. Perfect stone-to-stone alignment and razor-sharp detailing on intricate marble profiles.

100% Repeatability

Flawlessly replicate any complex pattern across hundreds of panels. Delivers consistent quality from the first cut to the final piece.

Complex Geometry

Carve deep 3D reliefs, undercuts, and delicate lattice screens (jali) that are physically impossible to execute using hand tools.

CNC SYSTEM SUPPORT & SPECIFICATIONS

Frequently Asked Questions

What CAD/CAM file formats are compatible with the CNC system?

Our systems integrate seamlessly with industry-standard CAD/CAM software. We provide native support for DXF, DWG, STP, IGES, and standard G-code (NGC/NC) formats, allowing direct toolpath generation from AutoCAD, Rhino, and Fusion 360 without translation loss.

What is the maximum carving depth and stone hardness limit?

The heavy-duty 3-axis spindle achieves a maximum vertical travel (Z-axis) of 350mm. Designed for high-density materials, it processes natural stones up to Mohs hardness scale 7, including granite, quartzites, and engineered composites with precise tool stabilization.

How frequently does the high-precision spindle require calibration?

We recommend executing an automated spindle laser alignment every 40 runtime hours. A comprehensive mechanical calibration check and axis-backlash test should be scheduled quarterly to maintain our guaranteed precision standard of ±0.05mm.

Is an active coolant filtration and recycling system required?

Yes, continuous stone carving demands active cooling. Our units include an integrated closed-loop liquid-coolant system that processes slurry and filters particulate down to 5 microns, recovering and recycling over 92% of the water volume automatically.
