How hard is the cutting material?

The carbide grade used in this pre-milling cutters delivers 7,000–9,000 HV / 1,500–2,000 HV hardness, which keeps the cutting edge sharp under continuous load.

Can you supply OEM or ODM parts, and how fast?

Yes. VPOINT TOOLS runs two factories in China (Chengdu and Dongguan) and accepts OEM and ODM orders. Standard samples and in-stock items ship within 24-48 hours; custom tooling is quoted per specification.

Pre-Milling Cutters

Pre-milling cutters, D 80-125 mm, Z=3+3 two-stage, bore 20/30 mm, width 35-65 mm. PCD edges for the pre-milling station of edge banders.

The VPOINT Pre-Milling Cutters are a CNC milling cutter. Ideal for pre-milling on edge banding machines, edge preparation before banding and removal of saw overhang and old glue lines.

Product Description

Design and Construction — a VPOINT end mill tool for CNC milling, sized for MDF and similar workpieces. The specification table below lists dimensions; the performance data table gives standard reference speeds and feeds to start with, and the FAQ covers selection, parameters and service. ISO 9001 production, batch-verified, custom sizes from drawings.

The VP-Y pre-milling cutter series pairs PCD cutting edges with steel cutterhead bodies for the pre-milling station of edge banding machines, in 80, 100, 120 and 125 mm diameters. Head width, bore and tooth count follow the specifications table and are produced to the station.

Design and Construction

The VP-Y pre-milling cutter series pairs PCD cutting edges with steel cutterhead bodies for the pre-milling station of edge banding machines. Diameters (ØD) run 80, 100, 120 and 125 mm with bores (Ød) of 20 and 30 mm, cutting widths (H) from 35 to 65 mm, and two-stage 3+3 tooth designs (Z=3+3) across the range.

How It Works

At the pre-milling station the cutter removes the saw overhang, chips and old glue line from the panel edge before banding, leaving a fresh, square edge the banding station can bond to. The 3+3 two-stage design roughs the edge with one tooth group and finishes it with the second, so a single pass delivers the finished edge. PCD edges hold their geometry in abrasive melamine-faced board across long shifts.

Applications

Pre-milling on edge banding machines
Edge preparation before banding
Removal of saw overhang and old glue lines
Panel furniture production lines

Suitable Materials

Melamine-faced particleboard
MDF and laminated boards
Veneered plywood
Solid wood edge panels

The PCD edges hold the milled edge square and clean in abrasive faced boards, keeping banding quality consistent.

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.

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.

Frequently Asked Questions

What is the Pre-Milling Cutters used for?

The VP-Y pre-milling cutter series pairs PCD cutting edges with steel cutterhead bodies for the pre-milling station of edge banding machines.

How do I choose the right size?

Refer to the specification table on this page: part numbers fix the cutting diameter, shank and cutting length. State the diameter, shank and cutting length you need when ordering.

Which materials does it suit?

Typical materials include Melamine-faced particleboard, MDF and laminated boards, Veneered plywood. Confirm the material grade and machining conditions for the specific tool before ordering.

What spindle speed and feed should I set for premilling MDF?

＋Start near 20,000–24,000 rpm spindle speed with the edge bander feed around 12–18 m/min, then fine-tune so the premill removes the saw overhang and old glue line in one clean pass.

Why PCD instead of brazed tungsten carbide for premilling?

＋On abrasive MDF and particleboard, PCD edges last 10–20 times longer (typical industry data cited in our comparison table above), so the bander runs far longer between tool changes.

How often should the premill knives be rotated or replaced?

＋Rotate the reversible inserts at the first sign of glue-line fuzzing; each edge has several usable sections, so a fresh edge takes seconds on the machine.
