Name: CN300 LASER CN300 Small Cannon Laser Edge Banding Machine
Brand: CNSK
SKU: CN300 LASER

Overview

Eighteen cells in the order printed on the sheet: 21.5-inch industrial computer, high-pressure beam on a heavy steel rail, separating agent, pre-milling, heat lamp, two-colour PUR no-cleaning pot, laser operating system, laser cooling system, swing-type pressing, double-stack disc trimming, scraping 1, scraping 2, hinged flat scraping, 35° end and tail trimming, four-head tracking, cleaning, polishing 1 and polishing 2.
The laser unit sits at station 07 with its cooling head directly behind it, ahead of the pressing, so both glued and laser band run through the same trim and finish.
Two extra cells over the standard CN300: the laser operating system and the cooling system.
Panels from 40 mm wide and 8 to 60 mm thick, band 0.4 to 3 mm thick and 12 to 65 mm wide.
16 to 23 m/min on a 9,400 mm frame, 950 mm wide and 1,800 mm high, with 22 kW installed.
The data sheet names this build Chengnuo Laser CN300 Small Cannon; the model cell still reads CN300, so the page carries CN300 LASER to keep the two apart.
Disc trimming, the two scraping heads, the hinged flat scraper and the 35° ends are unchanged from the standard build.

Station sequence

Station 01 is the 21.5-inch computer and station 02 the high-pressure beam on its rail; the laser unit is station 07 and its cooling system station 08, in the order printed on the sheet.

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

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

Separating agent

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

04

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.

05

Heat lamp

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

06

Two-colour PUR no-cleaning pot

The pot holds two PUR colours and switches between them without a solvent flush, and it sits outside the machine so the melt is kept apart from the EVA furnace.

07

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.

08

Laser cooling system

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

09

Swing-type pressing

The pressure roller swings on an arc and cushions the load at the joint instead of hitting the band flat.

10

Double-stack disc trimming

Two stacked disc heads trim the band top and bottom in one pass, so the overhang comes off square to the panel face.

11

Scraping 1

The first scraping head takes the trim-knife marks and surplus glue off the upper edge of the band.

12

Scraping 2

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

13

Hinged flat scraping

A hinged scraper follows the panel face and lifts surplus hot-melt off flat, with the angle set on the hinge.

14

35° end and tail trimming

The end heads cut at 35° and back off on their own when a thicker board or band comes through, so corners are not chipped.

15

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.

16

Cleaning

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

17

Polishing 1

Cotton wheels clean the finished edge on the first pass, taking the dust and the last of the glue off.

18

Polishing 2

The second pass finishes the edge after the first, for a higher sheen on the joint.

Values from the Chengnuo Laser CN300 technical data sheet in the 2026 configuration list. That sheet prints the model as CN300 and names the build Chengnuo Laser CN300 Small Cannon; the page carries CN300 LASER as the model designation and Small Cannon Laser Edge Banding Machine as the equipment name.

What the machine is built to do

Laser between glue and pressThe laser head and its cooler sit at stations 07 and 08, so a glued edge and a laser edge leave on the same settings.
Heat lamp and PUR potThe lamp pre-heats the board and the glue, and the two-colour pot switches adhesive without a solvent flush.
High-pressure beam on a railThe beam is a custom heavy section on a steel rail, sized for a 60 mm door blank.
Double-stack disc trimmingTwo discs trim top and bottom in one pass, so the laser joint is cut square rather than scraped down.
35° end trimmingThe end heads cut at 35° and back off on a thicker board, which keeps the corner of a lacquered door intact.
Two polishing headsPolishing 1 and 2 close the line, so a glue-free joint gets the same finish as a glued one.
