Name: FM730JC Servo-Forming Special-Shaped Edge Bander
Brand: CNSK
SKU: FM730JC

Overview

Twenty numbered cells: 21.5-inch industrial computer, separating agent, pre-milling, servo forming cutter 1/2, bottom chamfer, panel preheating, gluing on the board surface, servo tape feed with notch and band gluing, fast-melt glue, 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, trimming, scraping, notch trimming, cleaning and servo polishing.
The forming cutter is a servo pair on 7.5 kW spindles with more than twenty profile shapes held in the controller, so a wrap is milled rather than folded.
Bottom chamfer follows the cutter: the lower edge is chamfered to the notch contour, which is what lets the band fold under the panel instead of lifting at the corner.
Panel preheating, gluing on the board surface, servo tape feed and fast-melt glue, then transmission pressing: the band is fed, glued and pressed as a continuous web rather than as a cut length.
Four baking lamps and a heat gun keep the band soft through the seventeen pressing groups, which is the section that decides whether a tight radius holds.
Rough trimming, a four-speed dual-track end trim, trimming, scraping, notch trimming and servo polishing close the line.
5 m/min, 35 kW, 8,800 mm frame, 1,200 mm wide, 1,850 mm high, 4,000 kg: a slow, heavy line built for the profile rather than for throughput.

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

Bottom chamfer

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

06

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.

07

Gluing on the board surface

Adhesive is applied directly to the panel face, which is what a soft-formed or recessed profile needs before the band is laid into it.

08

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.

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

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

Trimming

The trim head takes the band overhang back to the panel face, on the line rather than at a second bench.

17

Scraping

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

18

Notch trimming

The notch edges are fine-trimmed after pressing, so the profile reads clean and the panel face stays flat.

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.

What the machine is built to do

Servo forming cutterTwo spindles mill the profile groove with the shape called from the screen, so a change of profile does not wait for a tooling set.
Seventeen pressing groupsSeventeen servo pressure components load the band along every curve, so a wrap closes without a second pass or a hand touch-up.
Four baking lamps and a heat gunThe band is kept soft across the whole forming section, so a tight radius folds without a white stress line.
Bottom chamferThe lower edge is chamfered to the notch contour, which is the detail that stops a wrap lifting at the corner.
Transmission pressingA driven section carries the panel through the forming zone at constant speed, so the band is loaded for its full contact length.
5 m/minA forming line runs slowly on purpose: the band needs time under the lamps and under the press to take a shape and keep it.
