Name: FM669JZ Narrow-Board Edge Bander, Single Scraper
Brand: CNSK
SKU: FM669JZ

Overview

Thirteen numbered cells: separating agent, pre-milling, heat lamp, gluing, pressing, head-and-tail trimming, rough and fine trimming, four-head tracking, scraping, precise flat scraping, cleaning and double polishing.
One scraping head, and a frame 600 mm shorter than the double-scraper build: 8,390 mm against 8,990 mm, with the same 850 mm bed width.
16 to 23 m/min, 15 kW, panels from 50 mm wide and 9 to 60 mm thick.
Four tracking heads before the scraper, so both ends close on the corner radius before the band is taken.
Precise flat scraping, cleaning and two polishing units: the finishing cells are present even though the second scraper is not.
One heat lamp and one pressing group on an EVA glue station.
21.5-inch industrial computer as station 01.
The double-scraper version is the same sequence with a second scraping head on an 8,990 mm bed; the two are quoted separately.

Station sequence

Station 01 is the 21.5-inch screen; thirteen numbered cells follow, with a single scraping head in tenth position.

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

Gluing

Hot-melt adhesive is melted and applied to the panel edge before the band is pressed on.

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

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.

10

Scraping

Upper and lower edges are scraped to remove trim knife marks, and surplus glue between band and panel comes off.

11

Precise flat scraping

A flexible scraper takes surplus hot-melt off the panel face and the band, leaving the edge flat before polishing.

12

Cleaning

Residual hot-melt is diluted and isolated before polishing, so it lifts off instead of being smeared along the edge.

13

Double polishing

Two sets of cotton wheels finish the edge, for a higher sheen on the joint than a single head gives.

Values from the FM669JZ single-scraper technical data sheet and the 2026 configuration list. The sheet carries no full-machine photograph; the image on this page shows the same FM669JZ frame in its double-scraper build, and the single-scraper bed is 600 mm shorter. The sheet describes 40 mm boards in its text while quoting 50 mm in the table; the table is used.

What the machine is built to do

Single scraper, shorter bed8,390 mm frame and one scraping head: the entry build of the FM669JZ pair, 600 mm shorter than the double-scraper machine.
Four-head tracking keptThe tracking heads are on both builds, so the corner is cut round the radius before the scraper takes the band.
Full finishing trainFlat scraping, cleaning and two polishing units remain, which is what separates this from a plain entry-level line.
50 mm narrow boardsGuide rails set for strips from 50 mm wide, with a 9 to 60 mm thickness range.
EVA glue stationHeat lamp, gluing and pressing in one group; no second adhesive system.
21.5-inch screenJob settings from one screen, with the thirteen station parameters recalled as a recipe.
