PCD Inserts Premill Cutter Heads
Premill cutter head with replaceable PCD inserts. Body stays in service — worn inserts are indexed or swapped in minutes.
The VPOINT PCD Inserts Premill Cutter Heads are a helical spiral cutter head with indexable knives. Ideal for pre-milling stations on edge banders, edge preparation before banding and high-volume panel lines.
The PCD inserts premill cutter head carries replaceable polycrystalline diamond inserts on a steel body at the pre-milling station of an edge banding line, for Biesse, Brandt, Cehisa, Holzher, Homag, SCM and Stefani machines. The head removes saw overhang and the old glue line before the band is applied, and worn inserts are indexed or replaced with the head still mounted. Bodies are produced to order for the station’s diameter, bore and width.
Design and Construction
The PCD inserts premill cutter head is a cutterhead body that carries replaceable PCD inserts for the pre-milling station of edge banding machines. The insert system keeps the head in service: worn inserts are indexed or swapped, and the body, its mounting and its balance stay in the machine. Heads are produced to order for the station’s diameter, bore and width.
How It Works
At the pre-milling station the head removes saw overhang and old glue line from the panel edge before banding. Replaceable PCD inserts bring fresh cutting edges in minutes; when an edge dulls in abrasive board, the insert is turned or replaced instead of sending the whole head for regrinding.
Applications
- Pre-milling stations on edge banders
- Edge preparation before banding
- High-volume panel lines
- Insert-system tooling programmes
Suitable Materials
- Melamine-faced particleboard
- MDF and laminated boards
- Veneered plywood
- Solid wood edge panels
Replaceable PCD inserts keep fresh edges on the station in abrasive boards, with the head staying mounted in the machine.
Material Comparison: PCD vs. Tungsten Carbide
The figures below are typical industry data for production woodworking. PCD does not replace carbide in every job — carbide remains the right choice for steel, cast iron and low-volume general work — but on abrasive sheet goods the difference in service life is decisive.
| Property | PCD Diamond (This Tool) | Tungsten Carbide |
|---|---|---|
| Hardness | 7,000–9,000 HV | 1,500–2,000 HV |
| Tool life on MDF / particleboard / melamine | 15–20× longer (500–1,200 h) | 30–60 h (baseline) |
| Tool life on solid hardwood | 10–13× longer (800–2,000 h) | 80–150 h (baseline) |
| Tool life on acrylic / plastics | 10–15× longer (1,000–3,000 h) | 100–200 h (baseline) |
| Resharpening cycles | 5–8 regrinds (thick tips up to 10); each pass removes only 0.2–0.3 mm of diamond | 4–6 regrinds, each removing more material |
| Surface finish | Ra ≤ 0.2 μm achievable, stable over the tool life | Ra ~0.8 μm typical, degrades as the edge wears |
| Thermal conductivity | 540–560 W/m·K — heat leaves the edge fast | ~80 W/m·K |
| Friction coefficient | ≈ 0.05 — lower cutting forces | ≈ 0.3 |
| Suited for | Abrasive engineered wood, laminates, composites, plastics, non-ferrous metals | General-purpose; the only choice for steel and cast iron |
Figures are typical published values; actual tool life depends on the workpiece material, feed rate, depth of cut, machine condition and maintenance schedule.
Delivery Scope
Cutter head made to order. Send the station diameter, bore and width, or the old head as a sample, and our engineering team will quote the exact specification. Replacement PCD inserts available separately.
Why Choose VPOINT
- One-year warranty on every cutter — defects in material or workmanship are covered for 12 months from delivery.
- Custom tooling — diameters, bores, cutting widths and tooth counts built to your drawing or sample.
- Non-standard fabrication — profiles and sizes outside the standard catalogue, including profile restoration.
- Resharpening service — cutters return to service after regrinding at a fraction of new-tool cost.
- Factory-direct since 2008 — ISO 9001 manufacturing in Sichuan and Dongguan, China; 40Cr chrome-molybdenum steel bodies; no trading intermediaries.
Send a drawing, a sample or a worn tool, and our engineering team will quote the exact specification you need.
Precision & Quality Control
Every cutter is inspected at micron level before shipment. Cutting diameter (ØD), bore (Ød), cutting width/height (B/H) and overall dimensions are measured against the values listed in the specifications table, and cutting edge runout and concentricity are verified on the assembled tool.
Tools measuring outside tolerance are reground or scrapped — they do not ship. Inspection is performed under our ISO 9001 quality system, with batch records retained for traceability.
Specifications
The head is built to order. State the edge bander model (Biesse, Brandt, Cehisa, Holzher, Homag, SCM, Stefani), the head diameter, the bore and the cutting width when ordering; insert grade and radius are matched to the panel edge and the banding speed.
