A sheet product, commonly made use of on affordable cabinets, and all set to construct cabinets and furnishings items. Melamine is a thermosetting plastic material put on a substrate, normally particle board. The product is warmed to heal or harden the resin. It contains formaldehyde, which is a well-known cancer causing compound. Melamine is offered in different sizes and thicknesses, along with a multitude of colors and patterns. The sheets are hefty and hard to collaborate with, as the material is prone to breaking when being reduced with conventional table saws. Industrial shops generally use huge and pricey CNC machines, controlled by CAD programs, which commonly have multiple cutter heads using router bits developed for these machines. The cutter heads are instantly transformed for the procedure being done.
The precision and speed in which these equipments removed parts is remarkable. A solitary machine can place the sheet, reduced all the components, drill whatever holes are needed, cut rabits and dados, with repeatability that is ideal from one sheet to the following.
Smaller industrial stores usually make use of saws outfitted with a 2nd blade, known as a scoring blade. This blade is smaller sized in diameter, and is placed simply in front of the major blade. This scoring blade turns the opposite instructions as the main blade and scores the bottom edge of the sheet which protects against the major blade from chipping the bottom side of the cut as the blade exits the cut. This blade could be ranged from the exact same electric motor using a belt drive, or a separate smaller motor that is often a direct drive.
The scoring blade attachment is readily available for lots of typical cupboard saws as an aftermarket accessory.
An additional approach utilized is to reduce the components 1/4 over sized and cut all 4 sides by 1/8 making use of either a jointer or router table. While this does include substantially to the labor it works in causing chip free cuts.
An additional choice is to make use of a saw blade developed for Melamine and other veneered products. These blades are described as ATB, or alternating top bevel. They are really reliable when sharp, when making use of an absolutely no clearance insert. Forrest Blade Company makes a blade called a Duraline Hey there AT blade which is very effective, in cutting both melamine and veneered plywoods. There are a number of blades makers that also have blades for this purpose.
Frequently when purchased from dealers, the sides are not cut, and the hard material makes handling the product quite unsafe. Gloves are a must, as the resin is extremely slim and fragile, making it like a serrated knife side. Sheets purchased from retail electrical outlets are cut and do not have these jagged edges, however gloves need to still be utilized, as the edges are still razor sharp.
Edges must be sealed to prevent formaldehyde from getting away into the air. Exposed sides and side banded or have solid Textured Melamine borders applied, much like plywood. TiteBond makes an adhesive specifically for melamine, as the standard white and yellow PVA clues will certainly not hang on the slick surface area.
