FM820JCDH — Skeleton-Line Grille Edge Bander

Overview

Eighteen processing cells after the screen and the conveyor: pre-milling, bevel sawing, PUR bevel gluing, grooving, synchronous pressing, trimming, four-head tracking, scraping, nail-rake grooving, cleaning, polishing, bevel-and-straight grooving, grille grooving and slitting.
The high-pressure beam runs on a track and holds the recessed face of a skeleton-line door flat, so the panel goes on without a pad or a levelling block.
Three skeleton forms come off the same line — straight skeleton line, 35° bevel skeleton line and grille slat strips, sized to your profile.
Nail-rake grooves and strip slitting are cut to 0.1 mm, so skeleton lines are fixed with a pneumatic nail gun instead of glue and a cold press.
Straight panels 9–60 mm, bevel panels 15–40 mm; width ≥ 60 mm straight, ≥ 80 mm bevel; 60 kW, 380 V, 0.7 MPa; frame 13,020 × 900 × 1,690 mm.

Station sequence

Twenty positions on the bed: the screen and the conveyor first, then the eighteen processing cells, from notch-line pre-milling to strip slitting.

High-definition wide screen

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

Track conveyor

A crawler conveyor supports the panel and drives it through every cell at constant speed.

Separating agent

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

Notch-line pre-milling

A double-blade unit at the inlet re-cuts the board edge after grille grooving and jointing, so the ripple marks and the vertical deviation those steps leave are gone before the band goes on.

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.

35° bevel saw

A profiling saw cuts the square edge to the 35° skeleton-line angle and mills the face in the same set-up, so bevel and straight banding run on one line.

PUR bevel gluing

An independent bevel gluing unit applies PUR evenly, so the bevel band bonds without a visible glue line.

Band grooving

Grooves are cut on the inner face of the band so it bends and presses cleanly around the corner.

Bevel and straight pressing

Pressure wheels load the bevel and the straight face together, so both bonds are made in one pass.

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.

Head-and-tail trimming, bevel and straight

Both formats share one end-trimming head, so the changeover does not wait for a second cut.

Straight and bevel fine trimming

One trimming head takes the overhang off the straight face and the bevel face, bringing both flush with the panel.

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.

Scraping

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

Nail-rake grooving

Grooves are cut in the panel underside, so skeleton lines can be fixed with a pneumatic nail gun instead of glue and a cold press.

Cleaning

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

Polishing

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

Bevel and straight edge grooving

One unit cuts both the bevel groove and the vertical straight-edge groove in a single pass, without changing the grooving head.

Grille grooving

A grooving unit cuts the grille pattern into panels and workpieces on the line.

Strip slitting

A dual-motor slitting assembly cuts bevel-edge and straight-edge strips from offcuts and damaged panels, so waste becomes skeleton-line stock.

What the machine is built to do

Track-fed high-pressure beamThe beam runs on a track and holds the recessed face of a skeleton-line door flat, so the panel needs no pad or levelling before banding.
Skeleton lines, three formsStraight skeleton lines, 35° bevel skeleton lines and grille slat strips come off the same line, sized to your profile.
Nail-gun assemblyRake grooves cut to 0.1 mm let skeleton lines be fixed with a pneumatic nail gun instead of glue and a cold press, which takes the cure time out of the schedule.
Offcuts turned into stripsThe slitting assembly turns offcuts and damaged panels into skeleton-line strips instead of waste.
35° bevel and straight on one bedA profiling saw sets the skeleton-line bevel angle, and the straight edge runs on the same bed; the format is chosen from the screen.
