FM669GD
Narrow-Board Edge Bander with Diamond Trimming
Diamond cutters and servo scraping are what a shop buys when the edge has to look finished under a lacquer: the FM669GD puts both on a narrow-board line, with a two-colour PUR pot between them.
Overview
- Sixteen numbered cells: separating agent, pre-milling, heat lamp, two-colour PUR pot, pressing, head-and-tail trimming, rough and fine trimming, diamond fine trimming, four-head profile tracking, servo double scraping, diamond profile tracking, servo diamond scraping, flexible flat scraping, cleaning and double polishing.
- Diamond fine trimming takes a shear cut instead of a crush cut, which is the difference between an edge that photographs clean and one that shows a faint line.
- Two tracking units and two scraping units: a profile tracker and a servo double scraper, then a diamond profile tracker and a servo diamond scraper, each following its own cutter.
- Servo on the scraping heads rather than a pneumatic stop: the scraper follows the band contour, so a 0.4 mm band and a 3 mm band are both taken clean.
- 8,990 mm frame, 16 to 23 m/min, 19.5 kW, panels from 40 mm wide and 9 to 60 mm thick.
- Two-colour PUR no-cleaning pot as the only glue system, which is a deliberate choice: a line this far into finishing is usually run on PUR work.
- Flexible flat scraping, cleaning and double polishing after the diamond cutters.

Station sequence
Station 01 is the 21.5-inch screen; the diamond and servo finishing cells sit from ninth position onward.
01
21.5-inch control screen
Industrial-grade 21.5-inch screen with a large graphical interface; parameters set by touch or input box, changes shown live.
02
Separating agent
A fine spray separates surplus glue from the panel face, so hot-melt does not mark the board after pressing.
03
Pre-milling
Two milling cutters re-finish the saw marks, burrs and out-of-square edges left by the panel saw, so the band seats on a clean face.
04
Heat lamp
The board and the glue are pre-heated before pressing, which keeps the bond even in cold weather.
05
PUR gluing
A no-cleaning PUR pot switches between two adhesive colours and dispenses evenly, for joints that have to hold and stay invisible.
06
Pressing
High-precision pressure wheels load the band evenly as it meets the panel, so the joint sits flat and holds.
07
Head-and-tail trimming
The band is cut flush at the leading and trailing ends — quickly, and without ragged corners.
08
Rough and fine trimming
Rough trimming takes the bulk of the overhang and the fine head finishes to the panel face; the two cuts sit on one unit, so the band is not re-clamped between them.
09
Diamond fine trimming
Diamond cutters shear rather than crush the band, so the joint does not pale or mark when it is lacquered.
10
Four-head corner tracking
Four driven heads round the corners at the leading and trailing ends, so the band follows the panel radius instead of cutting it square.
11
Servo double-edge scraping
Two scraping heads on servo drive, one for the band and one for the glue film, each positioned rather than sprung.
12
Diamond profile tracking
A diamond cutter on a tracking head follows the corner radius after the first cut, taking the band flush on both faces.
13
Servo diamond scraping
A diamond scraper under servo control takes the last film off the edge at a set depth, so a thin band is cleaned without being gouged.
14
Precise flat scraping
A flexible scraper takes surplus hot-melt off the panel face and the band, leaving the edge flat before polishing.
15
Cleaning
Residual hot-melt is diluted and isolated before polishing, so it lifts off instead of being smeared along the edge.
16
Double polishing
Two sets of cotton wheels finish the edge, for a higher sheen on the joint than a single head gives.

What the machine is built to do
- Diamond fine trimmingDiamond cutters shear the band instead of crushing it, so the joint keeps its colour and does not show a pale line after lacquering.
- Two cutters, two trackersA four-head profile tracker follows the first cut and a diamond profile tracker follows the second, each with its own scraper behind it.
- Servo scrapingThe scraping heads are driven rather than sprung, so they follow the contour of the band on both thin and thick stock.
- PUR only, on purposeA two-colour no-cleaning pot, for shops whose work has to hold in heat or moisture; there is no EVA furnace on this specification.
- Narrow-board bed8,990 mm frame with an annealed body and a finish-milled table, sized for strips from 40 mm wide.
- 21.5-inch screenSixteen station parameters on one industrial screen, recalled as a recipe.
