Ce que Cette Machine Résout
Trois problèmes de production éliminés par cette machine — avec des solutions ingénieriques et mesurables.
Le Problème
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.
Comment Cette Machine le Résout
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.
Le Problème
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.
Comment Cette Machine le Résout
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.
Le Problème
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.
Comment Cette Machine le Résout
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.
Inside the Machine — Core Components
Eight engineered subsystems that make this cutting line production-grade. Each component is sourced, built, and tested for industrial duty cycles.
1. Aluminum Gantry Frame & Workbench
Function
Provides the rigid X-Y-Z reference frame for servo-driven precision cutting. Aluminum extrusion is light enough for high-speed traverse but rigid enough to hold ±0.05mm repeatability.
Engineering Details
Industrial-grade 80×160mm aluminum extrusion with reinforced corners. X-axis travel 2,000-4,000mm, Y-axis 1,000-2,000mm, Z-axis 500-1,200mm. Adjustable feet for site-leveling; full frame footprint visible from any angle for visual inspection.
2. Industrial CNC Controller
Function
Brain of the machine. Reads G-code, drives the servo axes, manages the cutting wire temperature, and provides operator HMI for job setup and monitoring.
Engineering Details
FANUC-equivalent industrial controller (or SYNTEC depending on regional service support). 8" color HMI with toolpath preview. Network port for direct CAD/CAM file transfer. Recipe storage for common profiles (Roman columns, cornices, packaging insert library).
3. Hot Wire Cutting Head & Z-Axis
Function
The actual cutting element — a single 0.3-0.5mm nichrome wire stretched between two upper anchor points. The Z-axis lifts and lowers the head for multi-pass and 3D contour work.
Engineering Details
0.3mm wire for fine detail (5mm min radius); 0.5mm for higher-volume production. Temperature regulated to ~250°C via PID loop on cutting current. Active cooling fans at wire anchor points prevent terminal melting. Z-axis travel 500-1,200mm with ±0.1mm positioning.
4. Servo Motors & Ball-Screw Drives
Function
Position the cutting head with industrial precision. Servo drive on every axis eliminates the backlash and skipped-steps that plague stepper-driven hobbyist machines.
Engineering Details
Yaskawa or Mitsubishi servo motors (400-800W per axis) with absolute encoders. Precision-ground ball screws (C5 grade or better) for backlash-free positioning. Mechanical brake on Z-axis prevents drop on power loss.
5. Vacuum Hold-Down Table
Function
Secures lightweight EPS / EPP foam blanks to the worktable without clamps or jigs. Critical for fine-detail cutting where any workpiece movement = ruined part.
Engineering Details
Aluminum honeycomb table surface with thousands of vacuum suction holes. 7.5 kW vacuum pump pulls workpiece flat. Zone-control valves let operator activate only the table area in use. MDF spoilboard insert protects the table surface from accidental wire contact.
6. CAD/CAM Software & PC Workstation
Function
The design-to-machine pipeline. Operator imports CAD files (DXF, STL, IGES), generates the cutting toolpath, simulates the cut, and exports G-code to the CNC controller.
Engineering Details
Bundled industry-standard CAM software with EPS-cutting templates pre-loaded. Supports DXF, STL, IGES, G-code import. Visual toolpath simulator catches collisions before machining. Library of common architectural profiles (Roman columns, cornices, baseboards) ships with the machine.
7. Linear Rails & Guideway System
Function
Constrain the gantry and cutting head to precise X-Y-Z motion. Hardened linear rails handle the dynamic loads of high-speed traverse without flex or wear.
Engineering Details
THK or HIWIN linear guideways on all three axes — same hardware grade as CNC machining centers. Rated for 50,000+ km of travel before service. Sealed against EPS dust ingress. Lubrication ports for routine maintenance (NLGI-2 grease every 6 months).
8. Safety Enclosure & Light Curtain
Function
Encloses the working area with operator-visible barriers and emergency stop circuitry. Optional light curtain enables unattended-cell production (run a job overnight without an operator on duty).
Engineering Details
Aluminum-framed safety enclosure with clear acrylic panels for full visibility. E-stop on operator side. Door interlock cuts servo power within 100ms when opened during run. Optional Type 4 light curtain (IEC 61496-1) for unattended operation. CE certified per EN 60204-1.
Principe de Fonctionnement
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.
Avantages de Performance Ingénieriques
Chaque avantage soutenu par des spécifications mesurables — pas d'allégations marketing sans données.
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.

Product FAQ
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.
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.
