Name: H768 Laser Edge Bander with Maglev Tracking
Brand: CNSK
SKU: H768

Overview

Fourteen numbered cells: 21.5-inch industrial computer, separating agent, pre-milling, two-colour PUR no-cleaning pot, laser operating system, laser cooling system, pressing, rough and fine trimming, scraping, scraping, heavy-duty magnetic-levitation horizontal end trimming, magnetic-levitation tracking, polishing and polishing.
The order follows the data sheet as printed: rough and fine trimming and both scraping heads sit ahead of the end trim, and the tracking head comes after it.
Both carriages run on magnetic levitation, the end trim and the tracking head, which is the build difference against the H762.
The laser runs from its own operating system with a closed cooling circuit, and a two-colour PUR pot is fitted for the orders that still call for adhesive.
9,940 mm frame, 1,040 mm wide, 1,800 mm high, 52 kW, with the feed switchable in three steps, 32, 36 and 42 m/min.
Panels from 50 mm wide and 9 to 60 mm thick, band 0.4 to 3 mm thick and 12 to 65 mm wide.
Rough and fine trimming on one unit, two scraping heads and two polishing stations close the sequence.

Station sequence

Station 01 is the 21.5-inch industrial computer; fourteen numbered cells run from separating agent to the second polishing station. The order follows the data sheet as printed, with the end trim at station 11 and the tracking head at station 12.

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

PUR gluing

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

05

Laser operating system

The laser source, its power curve and the band feed are run from one controller, so a change of band is a recipe change rather than a re-setup.

06

Laser cooling system

A closed cooling circuit holds the laser at working temperature, so the bond stays even across a long shift.

07

Pressing

High-precision pressure wheels load the band evenly as it meets the panel, so the joint sits flat and holds.

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

Scraping

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

10

Scraping 2

The second scraping head repeats the pass on the lower edge, so both faces come off the band clean.

11

Heavy-duty magnetic-levitation end trimming

The end-trim carriage runs on a magnetic-levitation rail, so it follows the panel end without contact wear at high feed rates.

12

Magnetic-levitation tracking

The tracking head floats on a magnetic rail and follows the corner at speed, which is what a 42 m/min line needs at the ends.

13

Polishing

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

14

Second polishing

A second pair of cotton wheels follows the first, for a higher sheen on the joint than one pass gives.

What the machine is built to do

Maglev on both carriagesThe end trim and the tracking head are both floated, so neither is limited by a guide rail at 42 m/min.
Laser with a cooling circuitA closed loop holds the source at temperature, so the bond stays even across a shift.
PUR pot on the same frameA two-colour no-cleaning pot for the orders where an adhesive is specified rather than a laser bond.
Rough and fine on one unitBoth cuts sit on one trimming unit, so the band is not re-clamped between them.
Two scraping heads, two polishersThe film and the trim marks come off in sequence, and two polishing pairs finish the edge.
Lower frame than the H7621,800 mm high against 1,850 mm, on a machine that keeps the same station set and the same feed rates.
