Name: FM752JC Servo-Forming Edge Bander with PUR
Brand: CNSK
SKU: FM752JC

Overview

Twenty numbered cells: 21.5-inch industrial computer, separating agent, pre-milling, servo forming cutter 1/2, servo forming cutter 3/4, bottom chamfer, panel preheating, PUR gluing, servo tape feed with notch and PUR gluing, transmission pressing, baking lamps 1 to 4, heat gun, seventeen-group servo forming and pressing, rough trimming, four-speed dual-track head-and-tail trimming, fine trimming, scraping and groove trimming, servo flat scraping, cleaning and servo polishing.
Two servo cutter pairs: the first mills one face of the profile and the second the other, so a wrap is cut on both sides of the band in one pass instead of being folded onto a single groove.
PUR gluing rather than EVA: the no-cleaning pot is for joints that have to hold in a wet room, a bathroom or a hot climate, and it carries two adhesive colours.
8 m/min, 52 kW, 9,800 mm frame, 1,200 mm wide, 1,850 mm high, 4,600 kg.
Panels from 120 mm wide and 18 to 25 mm thick, band 0.5 to 0.7 mm thick and 30 to 65 mm wide.
Bottom chamfer, preheating, four baking lamps and a heat gun: the band enters the seventeen pressing groups warm, and it is held there until the shape sets.
Fine trimming, scraping with groove trimming, servo flat scraping and servo polishing finish a wrap that was cut, not just pressed.

Station sequence

Station 01 is the 21.5-inch industrial computer; twenty numbered cells run from separating agent to servo polishing.

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

Servo forming cutter 1/2

Two 7 kW spindles mill the profile grooves — J, C, W, arc, half-pass, ox-horn and drop shapes among more than twenty-five — with the shape called from the screen.

05

Servo forming cutter 3/4

A second pair of servo spindles mills the opposite face of the profile, so a wrap is cut on both sides of the band in one pass.

06

Bottom chamfer

The lower edge is chamfered to the notch contour, so the band folds under the panel instead of lifting at the corner.

07

Panel preheating

The panel and the band are brought up to temperature before the glue station, so the bond holds on a cold floor and in winter.

08

PUR gluing

A no-cleaning PUR pot switches between two adhesive colours and dispenses evenly, for joints that have to hold and stay invisible.

09

Servo tape feed and notch gluing

Tape feed is servo-matched to the panel speed; glue is applied in the notch and on the band at separate points.

10

Transmission pressing

A driven pressing section carries the panel through the forming zone at constant speed, so the band is loaded for its full contact length.

11

Baking lamps 1–4

Four lamps heat the band along the forming section, so it stays soft across a long profile and a cold shop floor.

12

Heat gun

Hot air softens the band before it enters the forming press, so a tight radius folds without a white stress line.

13

Seventeen-group forming press

Seventeen pressure components load the band along every curve and corner of the profile, so the wrap closes without a second pass.

14

Rough trimming

The first trim brings the band's upper and lower edges down to the panel faces and leaves the allowance for the finishing head.

15

Four-speed automatic dual-track head-and-tail trimming

Two tracks run the ends and the speed is switched in four steps, so a pair of panels is trimmed without dropping the feed rate.

16

Fine trimming

The finishing cut takes the overhang back to the panel face; this is the pass that decides how clean the joint reads.

17

Scraping and groove trimming

Trim marks and surplus glue are scraped off, and the groove edge is trimmed at the same station.

18

Precise flat scraping

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

19

Cleaning

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

20

Servo polishing

The polishing head is servo-driven and follows the profiled contour, so the cotton wheel stays on the band instead of the panel face.

Values from the FM752JC technical data sheet in the 2026 configuration list. The sheet prints the machine size as 9800 × 11200 × 1850 mm; a 11,200 mm width does not match a 1,200 mm bed, so the width is read as 1,200 mm here. The sheet also gives the edge type as special-shaped and the machine weight as 4,600 kg.

What the machine is built to do

Two servo cutter pairsA profile cut on both faces of the band closes a wrap that a single groove leaves open at the profile edge.
PUR gluingA no-cleaning pot with two adhesive colours, for the joints where EVA will not hold: bathrooms, wet areas and humid export markets.
Seventeen pressing groupsThe band is loaded along the whole profile, so the wrap does not need a second pass or a hand touch-up.
Four lamps and a heat gunThe band stays soft from the cutter to the press, which is what a tight radius needs on a cold floor.
Servo flat scrapingA servo scraper follows the profiled face at a set depth, so the film comes off without marking the board.
8 m/minFaster than the 5 m/min forming build, with two cutter pairs doing the work that one pair does there.
