Name: FMK850B High Pressure Beam Track Type Edge Bander
Brand: CNSK
SKU: FMK850B

Overview

Twenty-one cells in the order printed on the sheet: synchronous caterpillar conveyor, heavy-duty pressure beam, wide screen, separating agent, pre-milling, heat lamp, electric glue pot, heated pressing group 1, fast-melt tank, glue applicator, heated pressing group 2, servo fine trimming, unpowered trimming, servo scraping, head-and-tail trimming, flexible flat scraping, four-head tracking, cleaning, polishing, horizontal and vertical grooving and the track synchronous motor.
Same station set as the FMK850A, on a 7,700 mm frame instead of 7,960 mm, which is the difference a tight bay decides.
26.3 kW installed against 28.95 kW on the FMK850A, on the same 380 V supply and the same 0.7 MPa air.
Panels from 60 mm wide and 9 to 60 mm thick, band 0.4 to 3 mm thick and 12 to 65 mm wide.
16 to 23 m/min, body weight 3,400 kg, transmission by synchronous track.
Two glue applications with a heated pressing group after each, so the second pass is made on a warm band.
Grooving at station 20 and four-head tracking before cleaning and polishing.

Station sequence

Station 01 is the synchronous caterpillar conveyor and station 02 the pressure beam; the twenty-one cells follow the order printed on the sheet, the same order as the FMK850A.

01

Synchronous caterpillar conveyor

A caterpillar belt drives the panel through the line with continuous power, so the feed stays constant under a heavy pressure beam.

02

Heavy-duty pressure beam

A custom heavy-section beam holds the panel flat while the band is pressed, which is what a door blank needs at 60 mm.

03

High-definition wide screen

A wide touch screen with fingertip control; a mouse and keyboard can be added if the operator prefers them.

04

Separating agent

A fine spray separates surplus glue from the panel face, so hot-melt does not mark the board after pressing.

05

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.

06

Heat lamp

The board and the glue are pre-heated before pressing, which keeps the bond even in cold weather.

07

Electric glue pot

An electrically heated pot holds the EVA melt, with the pot temperature and glue output set from the screen.

08

Heated pressing

The pressing wheels are heated, which raises the band and the glue at the joint and holds the bond on a cold shop floor.

09

Fast-melt glue

The fast-melt unit brings the adhesive to working temperature in less time, so a cold start does not hold up the line.

10

Glue applicator

The applicator melts the hot-melt and spreads it on the panel face and the band as the panel passes.

11

Heated pressing

The pressing wheels are heated, which raises the band and the glue at the joint and holds the bond on a cold shop floor.

12

Servo fine trimming

Four axes — up-down and front-back — run on servo with micron-level error; the trimming angle is set numerically on the screen, so a changeover needs no test board.

13

Unpowered trimming

The trimming head runs without its own drive motor: fewer wearing parts and less to clean between bands.

14

Servo scraping

A servo motor on a precision guide rail tracks the panel face; scraping depth and pressure are closed-loop, so the edge is neither over- nor under-scraped.

15

Head-and-tail trimming

The band is cut flush at the leading and trailing ends — quickly, and without ragged corners.

16

Flexible flat scraping

A sprung scraper follows the panel face instead of a fixed depth, so surplus hot-melt comes off without cutting into the board.

17

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.

18

Cleaning

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

19

Polishing

Cotton polishing wheels clean the finished edge, leaving it smooth and even with the panel face.

20

Horizontal and vertical grooving

One grooving unit cuts across the panel or along the edge, so the machine also produces the grooves a groove-profile door needs.

21

Track synchronous motor

A synchronous motor drives the track, so the panel position and the station timing stay locked together.

Values from the FMK850B technical data sheet in the 2026 configuration list. The model cell of that sheet still reads FMK850A, a copy-over from the FMK850A file; the page follows the file name and the sheet's own power and size, which are 26.3 kW and 7,700 × 950 × 1900 mm.

What the machine is built to do

Two hundred millimetres shorter7,700 mm against 7,960 mm: the shorter frame is the one to quote when the bay is fixed and the panel length does not need the longer bed.
Lower installed load26.3 kW instead of 28.95 kW on the same station set, which matters where the supply is already committed.
Heated pressing, twiceBoth pressing groups are heated, so the band is warm at the joint both times it is pressed.
Servo trimming and scrapingServo positioning on the trimming and scraping heads keeps the cut even across the run.
High-pressure beam on a trackThe beam runs on a track and holds the panel flat before the glue stations.
Grooving includedA horizontal and vertical grooving unit closes the line, so groove profiles come off the same machine.
