- Travel range: At least 1,250×1,000 mm for half-sheet processing. 2,500×1,250 mm for full sheets.
- Vacuum table: Essential for efficient sheet processing
- Good spindle: HF spindle preferred for clean acrylic edges
- Dust extraction: Required for all materials
BZT Recommendations
- PFU-S: Steel frame all-rounder with sufficient travel for most sign work
- PFG-S: Large format for full-sheet nesting
CNC Software for Sign Making
- VCarve Pro/Aspire: Industry standard for sign makers — excellent V-carving, nesting, import of customer artwork
- CorelDRAW: Design + DXF export for customer-facing work
- Adobe Illustrator: Design + SVG/DXF export
V-Carving for Signs
V-carving is the signature technique for CNC sign making:
- Variable-depth cuts create elegant, classic lettering
- Works with any font — serif fonts look particularly good
- Single V-groove cutter handles many text sizes
- Paint-filled V-carvings have stunning visual impact
Business Tips for Sign Makers
- Standardize materials: Stock 3–4 standard materials and thicknesses
- Template library: Build reusable templates for common sign types
- Pricing: Material cost + machine time + finishing + markup
- Samples: Display samples attract customers — keep a portfolio
FAQ — Frequently Asked Questions
