80x20xH50 Cutting Milling Tools Diamond PCD Pre Milling Cutter For Edgebander

Product Description

Dull pre-milling leaves a torn edge, and edge banding that lands on a torn edge lifts within weeks. This 80 x 20 x H50 mm pre milling cutter squares the panel edge before the banding goes on: 80 mm outer diameter, 20 mm inner diameter, 50 mm cutting height, diamond PCD edge on a tungsten carbide body, 2.2 kg per set. The 20 mm bore mounts on the machine arbor, so it runs on the edgebander already in the shop. Customization supported, price on request.

Three things go wrong on an edgebander with a worn pre-milling station: the panel edge reaches the glue pot torn instead of square, the banding bridges that tear and lifts a few weeks later, and the operator ends up sanding edges by hand to hide it. Pre-milling is the cut that decides which of the three you get.

This is a PCD pre milling cutter in 80 x 20 x H50 mm: 80 mm outer diameter, 20 mm inner diameter, 50 mm cutting height, 2.2 kg per set. The body is tungsten carbide — TCT — and the cutting edge is diamond PCD, polycrystalline diamond, the grade that keeps its edge on abrasive board and laminate.

Pre-milling means removing a thin slice from the panel edge before the banding is applied. The cutter squares that edge and clears the splinters and rough fibre, so the banding meets a clean face and bonds across its full width instead of bridging a torn surface.

The 20 mm bore takes the cutter onto the machine arbor or collet system, so it spins at spindle speed and leaves a smooth cut rather than a sanded one. Diamond tips hold their form, so one set stays in service longer between changes. Customization is supported for other diameters, bores and heights. Price on request from Shunhongyu.

Product Features

What separates a pre-milling cutter that holds an edge from one that polishes it away:

• Diamond PCD on the edge. Polycrystalline diamond is the hardest cutting material in this cutter, so abrasive board and laminate wear the 80 mm disc slower than a plain carbide edge.
• Tungsten carbide body. The body is TCT, tungsten carbide, which carries the 80 mm outer diameter without flexing at spindle speed.
• 80 mm outer, 20 mm inner. The 80 mm disc runs on a 20 mm inner diameter, the arbor size the cutter is built to.
• 50 mm of cutting height. 50 mm of edge in one pass means the depth is set once for the panel edge.
• 2.2 kg per set. One set weighs 2.2 kg, the figure to use when you check the load on the arbor.
• Pre-milling, not fine trimming. This cutter removes material before the banding goes on; fine trimming cuts the overhang afterwards.
• Splinters and rough fibre come off. The PCD edges shear torn fibre away, leaving a face the glue can key into.
• Customization supported. A different diameter, bore or height is produced to your drawing.
• Price on request. The quote follows the size string and the quantity you need.

Product Advantages

On a dull pre-milling station the usual choice is a cheaper carbide cutter or another hand-sanded edge. What a buyer gets here:

• The edge holds between changes. Diamond PCD does not round off on abrasive board the way a carbide edge does, so the set stays on the arbor longer.
• Banding bonds across its full width. A squared, clean edge gives the glue a surface to key into, which is what stops the banding lifting at the seam.
• The edge is set in one pass. 50 mm of cutting height on an 80 mm disc covers the panel edge, so depth is set once.
• Fits the arbor already on the machine. A 20 mm inner diameter and 2.2 kg per set go onto the edgebander's existing arbor.
• Fewer stops in a shift. Slower wear on the PCD edge means fewer swaps and less re-setting of depth.
• One cutter for abrasive board. Wood, laminate and edge banding materials all run on the same 80 mm disc.
• Non-standard sizes are a quote. Customization is supported, so a bore or height off the 80 x 20 x H50 mm list is priced on request.
• Reorder by one size string. 80 x 20 x H50 mm is the whole size, so one string reorders the set.

Frequently Asked Questions

What size is this pre milling cutter?

80 x 20 x H50 mm — 80 mm outer diameter, 20 mm inner diameter, 50 mm height. Those three numbers cover the disc, the arbor bore and the cutting height, so the fit can be checked before an order.

Will it fit the arbor on my edgebander?

Yes, if that arbor is 20 mm. The inner diameter is 20 mm, which is the bore the cutter is built to, so it mounts on the machine arbor or collet system without an adapter.

What does PCD mean, and why does it matter here?

PCD is polycrystalline diamond, a synthetic diamond grade used for the cutting edge. It is the hardest material in this cutter, so an 80 mm disc keeps its edge on abrasive board and laminate instead of rounding off like plain carbide.

Is this a pre-milling cutter or a fine trimming cutter?

Pre-milling. It removes a thin slice from the panel edge before the banding is applied; fine trimming is a different tool that cuts the overhang afterwards.

What materials does it cut?

Wood, laminate and edge banding materials. Pre-milling is abrasive work, which is why the edge on this cutter is diamond PCD on a tungsten carbide body.

How much does one set weigh?

2.2 kg per set. That is the figure to check against the load your arbor and spindle are set up for.

Can you make a different diameter, bore or height?

Yes. Customization is supported, so a size other than the listed 80 x 20 x H50 mm is quoted on request — send the drawing or the three numbers with the quantity.

How do I get the price?

Price is on request. Send the SKU PMC002 - 80*20*H50 with the quantity you need and a quote follows; the same string covers the size, so there is nothing else to specify.
