Eight engineered subsystems that make this machine production-grade. Each component is sourced, built, and tested for industrial duty cycles.
1. Vertical Cutting Frame
Function
High-strength heavy-duty frame with vertical cutting wire for precise and smooth 3D shaping — the structural backbone holding all moving subassemblies (servo drive, wire tension, table).
Engineering Details
Welded steel column construction with aluminum extrusion (40x40 mm or 60x60 mm) cross-rails for vibration damping. Heat-treated and powder-coated finish. Travel: X 2000-4000 mm / Y 1500-2500 mm / Z 1000-2000 mm depending on model. TUV / Bureau Veritas certified. Mounting bolt M16 grade 10.9 for industrial floor.
2. Cutting Wire System (Multi-Diameter Ni-Cr)
Function
High tensile Ni-Cr cutting wire ensures stable cutting, smooth surface and high dimensional accuracy. Wire diameter selectable from 0.3-0.7 mm to match material density and detail complexity.
Engineering Details
Multi-diameter Ni-Cr alloy wire: 0.3mm for fine detail (1mm features), 0.4mm standard, 0.5-0.7mm for thick foam blocks. Dual-spring tension self-corrects wire stretch — eliminates mid-batch wire breakage. Hot-wire current PID-controlled per wire size (8 amp max per channel).
3. Drive System (Yaskawa / Mitsubishi Servo X/Y/Z/A)
Function
High-quality servo motor and transmission system ensures stable and continuous operation. 4-axis simultaneous motion (X+Y+Z+A rotation) enables true 3D shapes — cylinders, cones, helical signs, decorative sculpture.
Engineering Details
Yaskawa Sigma-7 or Mitsubishi MELSERVO J5 servo motors (400-800 W per axis) with 23-bit absolute encoders. Precision-ground ball screws (C5 grade) for backlash-free positioning. ±0.15mm repeatability across 5000+ cycles. Mechanical brake on Z-axis prevents drop on power loss (EN 1010-3 compliant).
4. Cutting Table (Large Flat Platform)
Function
Large and flat table with stable platform ensures smooth workpiece feeding and accurate cutting. Phenolic resin surface (red-brown) is wear-resistant and low-friction for foam block sliding.
Engineering Details
Phenolic resin tabletop (15-20 mm thick) mounted on welded steel frame. Optional 4-pneumatic-cylinder lift (illustrated) for variable workpiece height. T-slot perimeter for jig clamping. Surface flatness ≤0.3 mm across 4-6 m table length. Optional rotary 4th axis (A) for cylindrical pieces.
5. Control System (Independent Cabinet + PLC + CAD/CAM PC)

O Que Esta Máquina Resolve
Três problemas de produção eliminados por esta máquina — com soluções engenheiradas e mensuráveis.
O Problema 1
Standard hot-wire continuous cutters (SPQ, SPB) can only do straight cuts — they cannot produce the decorative Roman columns, cornices, or custom packaging contours that command 3-5× the price of straight-cut sheets.
Como Esta Máquina Resolve
CNC-EPS uses servo-driven X/Y/Z axes + a single 0.3mm hot wire that traces any 2D contour or limited 3D profile from a DXF or G-code file. Cuts complex architectural and packaging shapes a standard cutter cannot do.
O Problema 2
Stepper-motor hobbyist CNC foam cutters drift over long traverses, accumulate backlash, and cannot maintain repeatability for production runs — fine for one-offs but not for paying customers.
Como Esta Máquina Resolve
Industrial CNC controller drives servo motors + ball screws on every axis. ±0.05mm repeatability across the full 4,000mm × 2,000mm × 1,200mm envelope. Production-grade for repeating customer orders.
O Problema 3
Custom-shape EPS production usually means hand-cutting with template-and-router or sloppy CNC — both produce variable quality that fails QC and frustrates buyers of premium architectural products.
Como Esta Máquina Resolve
CAD/CAM workflow: design in standard software, export DXF or G-code, import to HMI, preview the toolpath, run the cut. Vacuum hold-down keeps lightweight EPS stable. Quality is consistent from piece 1 to piece 1000.
Princípio de Funcionamento
CNC-EPS is a 3-axis (or optional 4-axis) servo-driven gantry-style hot-wire cutter. Workflow: design in CAD → export DXF or G-code → import to HMI → place foam blank on vacuum table → preview toolpath → run. The hot wire traces the programmed contour while the foam stays still on the vacuum-held table.
Step 1
1. Design in CAD
Designer creates the 2D profile or 3D shape in any standard CAD software (AutoCAD, SolidWorks, Rhino, Fusion 360). Export as DXF (2D) or G-code (3D contour). Common profiles ship in the bundled library.
Step 2
2. Import + Preview on HMI
Operator loads the file via USB or network. The HMI renders the toolpath visually so the operator can verify the cutting sequence, depth of cut, and traverse moves before pressing start. Estimated cutting time displays automatically.
Step 3
3. Foam Blank Loading
EPS blank (or EPP / XPS / PU) is placed on the vacuum hold-down table. Vacuum pump activates; foam is locked to the table surface — no clamps needed, even on irregular blanks.
Step 4
4. CNC Hot-Wire Contour Cut
Single 0.3-0.5mm nichrome wire heats up to ~250°C. Servo-driven X/Y/Z axes guide the wire along the programmed toolpath. Real-time temperature compensation adjusts wire current as cutting speed changes through corners and curves.
Step 5
5. Finished Piece De-Mounting
Vacuum releases; operator lifts the finished piece off the table. Cycle time depends on contour complexity — typical 5-15 minutes per decorative column or 1-3 minutes per packaging insert.
Vantagens de Desempenho Engenheiradas
Cada vantagem respaldada por especificações mensuráveis — sem alegações de marketing sem dados.
4-Axis Hot-Wire (X/Y/Z/A)
X/Y/Z + A rotation
vs Generic CNC: 2-axis only
Full 4-axis simultaneous motion enables true 3D shapes — cylinders, cones, helical signs, decorative sculpture. Generic 2-axis competitors can only do extruded 2D profiles.
CAD/CAM File Compatibility
AutoCAD/SolidWorks/Mastercam/CAXA/UG/CDR
vs Proprietary-format competitors: 2h conversion
Direct import of DXF, G-code, STL, IGES from any major CAD/CAM software. Designer exports from AutoCAD/SolidWorks/Mastercam, USB-transfers, machine runs in 2 minutes.
Servo Position Repeatability
plus/minus 0.15 mm
vs Stepper-motor competitors: plus/minus 1 mm
Yaskawa Sigma-7 or Mitsubishi J5 servo motors (400-800W per axis) with 23-bit absolute encoders. C5-grade precision ball screws. Maintains plus/minus 0.15 mm repeatability across 5000+ cutting cycles.
Hot-Wire Diameter Range
0.3-0.7 mm Ni-Cr alloy
vs Single-wire competitors: 0.4 mm only
Multiple wire diameter support: 0.3mm for fine detail (1mm features), 0.4mm standard, 0.5-0.7mm for thick foam blocks. Hot wire current PID-controlled per wire size.
Mechanical Z-Brake Safety
Power-loss drop prevention
vs No-brake competitors: Z drop on power-loss
Mechanical brake on Z-axis engages instantly on power-loss — prevents heavy cutting frame dropping onto workpiece (damaging both machine and workpiece). EN 1010-3 cutting machine safety compliant. CE certified.
Position Accuracy
±0.1 mm
vs stepper hobbyist CNC: ±0.5-1.0 mm
Industrial CNC controller + servo motors + ball screws hold ±0.1mm positioning anywhere in the work envelope. Repeatability is even tighter at ±0.05mm.
Min Cutting Radius
5 mm
vs standard hot-wire frame: cannot do tight radii
A 0.3mm wire can trace down to 5mm inside radius — opens up applications like packaging inserts and decorative profiles that standard cutters cannot do.
Travel Speed Range
50-500 mm/min
vs manual contour cut: 20-100 mm/min
Servo drives ramp speed up on straight runs and slow down through tight corners automatically — productivity matches contour complexity.
Repeatability (Production)
±0.05 mm
vs manual template + router: ±0.5-1.0 mm
Critical when a customer orders 1,000 identical decorative columns or packaging inserts — every piece is dimensionally identical, no manual variation.
Supported Workpiece Size
4,000 × 2,000 × 1,200 mm
vs hobbyist CNC: 1,000 × 600 × 400 mm
Large work envelope handles full-size architectural columns and pattern blanks for industrial casting — not just small craft pieces.

The questions buyers ask most often before placing an order.
How is CNC-EPS different from the SPQ-B and SPB-Q cutting lines?
Three categories of difference. (1) Geometry: CNC-EPS cuts any 2D contour and limited 3D profiles; SPQ/SPB only cut straight lines (horizontal, vertical, cross-cut). (2) Volume: CNC-EPS does 30-200 pieces/day of custom shapes; SPQ/SPB do 12-25 tons/day of standard sheets. (3) Pricing: CNC products command 3-5× the price per piece of standard sheets. Use SPQ/SPB for commodity insulation; use CNC-EPS for architectural decoration, packaging inserts, and signage.
Is a CNC hot wire foam cutting machine the same as a hot wire block cutter?
Same heating principle, different machine. A hot wire block cutter (our CM / SPQ / SPB lines) pulls the block through a fixed array of tensioned wires and cuts straight lines only — that is how you make flat insulation board and packaging sheet. A CNC hot wire foam cutting machine drives a single wire on servo X/Y/Z axes along a programmed toolpath, so it follows curves, tapers and contours a fixed array cannot produce. Choose by output, not by price: flat sheet at volume goes to the block cutter; cornices, letterforms, packaging inserts and casting patterns need the CNC.
Can the CNC-EPS do true 3D shapes, or only 2.5D contours?
It does 2.5D (a contour that extrudes through the foam, like a Roman column profile that's the same all the way through) very well, and limited 3D (where the wire angle changes mid-cut) on the 4-axis configuration. For true 3D sculpting (e.g., complex statues with overhangs), you need a 5-axis machine plus router head, which is not in our product line. Most of our customers run 2.5D — that's where the EPS architectural and packaging market is.
What software is bundled, and do I need to license CAD separately?
Bundled: FoamCut (or equivalent) CAM software for toolpath generation — license included with the machine. You provide your own CAD software for design (AutoCAD, SolidWorks, Rhino, Fusion 360 — any standard package). The CAM software imports DXF, STL, IGES, and standard G-code, so it works with whatever you already use.
How long does a typical architectural column take to cut?
A 2.5m-tall Roman column with 4 flutes and capital details typically takes 8-15 minutes of cutting time, plus 2-3 minutes for setup. So you can do 30-50 columns per day on a single shift. Simpler cornices and baseboards run 1-3 minutes per piece — 200-400/day.
What's the minimum cutting radius I can achieve?
With the 0.3mm wire: 5mm inside radius. With the 0.5mm wire (more durable, faster cutting): 10mm inside radius. Below 5mm you start running into wire-tension issues. For tighter detail you would need a CNC router head — that's a different machine class.
Can I cut EPP, XPS, or PU foam in addition to EPS?
Yes — all three. EPP cuts cleaner than EPS (higher density, less crumble). XPS cuts well but slower. PU foam cuts OK but produces strong fumes — make sure ventilation is rated for PU off-gassing if you'll do high volumes. Density range 12-45 kg/m³ across all materials.
Does the CNC-EPS support 220V/60Hz markets (US, parts of Latin America)?
Yes — factory build option. We swap the servo drives, controller voltage taps, and vacuum pump motor to 220V/60Hz equivalents. No price difference; 2-week lead time adjustment.
How long does the cutting wire last, and what's the replacement procedure?
Wire life: 200-400 hours depending on cut complexity. Fine-detail jobs with lots of tight corners shorten life; long straight runs extend it. Replacement is a 5-minute job: open the enclosure, release wire tension, swap the wire spool, re-tension with the supplied torque gauge. Spare wire stock ships with every machine — 500m for the first year.
Is operator training included? In what language?
Two options: (1) factory training in Qingdao for 3 days during pre-shipment testing (you cover travel); (2) on-site training at your facility for 5 days (you cover travel + accommodation). Training covers G-code basics, CAD/CAM workflow, common-profile library, and maintenance. Materials and HMI available in EN / ZH / ES / PT / FR / RU / AR.
How is the CNC-EPS shipped, and what's the floor-space requirement?
Ships in 1× 40HQ container (gantry disassembled into 4 sections, electrical cabinet separate). Floor space for the typical 3000×1500mm work envelope: 5m × 3m machine footprint + 2m service clearance on each side = ~7m × 5m installation area. Power: single 32A 380V (or 50A 220V) circuit. Air: 6 bar compressed air supply.
