Production of final sized panels of prelaminated particle board,MDF,Plywood with HPL,etc without chipping of the laminate is an everyday requirement faced by all panel processing units.A premilling cutterhead also called a jointing cutterhead is a primary requirement to produce tear free edges for tightly sealed edgebanding.

Why premilling or jointing ?

If the sized panel is taken directly from the Panelsaw and edgebanded a tight closing of the edgebanding is not possible.Moreover,productivity on the Panelsaw is also affected since even slight chipping while cutting will necessitate stoppage of the machine to change the Sawblades.

Premilling machining process

When sizing the board on the Panelsaw there should be an oversize of upto 2mm.This extra material will be removed by the Premilling cutterhead.Jointing of the boards after sawing will clear any slight chipping as well as prepare the edge of the board for high quality edgebanding.
