Panel Saw
A panel saw is any type of sawing machine that cuts sheets into sized parts. Panel saws can be vertical or horizontal. Typically, vertical saws take up less floor space. Horizontal machines are typically large table saws with a sliding feed table that pushes the material through the blade. Table saws without the sliding feed table can also cut sheet goods. Vertical saws have two cost types, low cost and higher cost. Both types have the saw traveling through the short side of the sheet called cross cutting. For cutting lengthwise ( rip) cut, the lower cost models, have the user slide the material through the saw while the higher cost models have the saw travel through the stationary material. A sliding panel saw was invented by Wilhelm Altendorf in 1906 in Germany. Its invention set a new standard in woodworking, with dramatic differences from traditional machines. Up to that time, a conventional table saw had no mechanism for edging, meaning that for the first and second lo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rip Cut
The rift sawn rip cuts are perpendicular to the center of the log In woodworking, a rip-cut is a type of cut that severs or divides a piece of wood parallel to the grain. The other typical type of cut is a ''cross-cut'', a cut perpendicular to the grain. Unlike cross-cutting, which shears the wood fibers, a rip saw works more like a series of chisels, lifting off small splinters of wood. The nature of the wood grain requires the shape of the saw teeth to be different thus the need for both rip saws and crosscut saws; however some circular saw blades are ''combination blades'' and can make both types of cuts. A rip cut is the fundamental type of cut made at a sawmill. Definitions ''Rip cut'' comes from ''rip'': to split or saw timber in the direction of the grain, and ''cut'': to divide with a sharp-edged instrument."Rip v. 2." def. 2.a., "cut v." def. 7.a., "rive v.1." def. 4 and "kerf" def 2.a.

Solid Wood
Solid wood is a term most commonly used to distinguish between ordinary lumber and engineered wood, but it also refers to structures that do not have hollow spaces. Engineered wood products are manufactured by binding together wood strands, fibers, or veneers with adhesives to form a composite material. Engineered wood includes plywood, oriented strand board (OSB) and fiberboard. The fact that a product is made from solid wood is often touted in advertisements. However, using solid wood has advantages and disadvantages. Comparison with engineered wood Perhaps the greatest advantage of solid wood is that the wood is the same all the way through, so repairs are relatively easy. Repairs to veneer are much more difficult and sometimes impossible. Solid wood furniture is strong enough to easily satisfy all furniture applications, and it can last for centuries. Society is still questioning whether furniture made of plywood (often made from pine) can do the same. Plywood and other engi ...

Plywood
Plywood is a material manufactured from thin layers or "plies" of wood veneer that are glued together with adjacent layers having their wood grain rotated up to 90 degrees to one another. It is an engineered wood from the family of manufactured boards which include medium-density fibreboard (MDF), oriented strand board (OSB) and particle board (chipboard). All plywoods bind resin and wood fibre sheets (cellulose cells are long, strong and thin) to form a composite material. This alternation of the grain is called ''cross-graining'' and has several important benefits: it reduces the tendency of wood to split when nailed at the edges; it reduces expansion and shrinkage, providing improved dimensional stability; and it makes the strength of the panel consistent across all directions. There is usually an odd number of plies, so that the sheet is balanced—this reduces warping. Because plywood is bonded with grains running against one another and with an odd number of composite part ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Medium-density Fibreboard
Medium-density fibreboard (MDF) is an engineered wood product made by breaking down hardwood or softwood residuals into wood fibres, often in a defibrator, combining it with wax and a resin binder, and forming it into panels by applying high temperature and pressure. MDF is generally denser than plywood. It is made up of separated fibres but can be used as a building material similar in application to plywood. It is stronger and denser than particle board. The name derives from the distinction in densities of fibreboard. Large-scale production of MDF began in the 1980s, in both North America and Europe. Physical properties Over time, the term "MDF" has become a generic name for any dry-process fibre board. MDF is typically made up of 82% wood fibre, 9% urea-formaldehyde resin glue, 8% water, and 1% paraffin wax. The density is typically between . The range of density and classification as light-, standard-, or high-density board is a misnomer and confusing. The density of the b ...

Laminate Panel
Laminate panel is a type of manufactured timber made from thin sheets of substrates or wood veneer. It is similar to the more widely used plywood, except that it has a plastic, protective layer on one or both sides. Laminate panels are used instead of plywood because of their resistance to impact, weather, moisture, shattering in cold (ductility), and chemicals. Laminate panel layers (called veneers) are glued together with adjacent plies having their grain at right angles to each other for greater strength. The plastic layer(s) added for protection vary in composition, thickness, color and texture according to the application. Types A number of varieties of laminate panel exist for different applications. *Plywood + ABS pipes ;Panels *Plywood + FRP laminate panels *Plywood + aluminum laminated panels *Lightweight composite panels Sizes The most commonly used thickness range from to and , in a variety of colours and textures. Applications Laminate panels are used in man ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Melamine Resin
Melamine resin or melamine formaldehyde (also shortened to melamine) is a resin with melamine rings terminated with multiple hydroxyl groups derived from formaldehyde. This thermosetting plastic material is made from melamine and formaldehyde. In its butylated form, it is dissolved in ''n''-butanol and xylene. It is then used to cross-link with alkyd, epoxy, acrylic, and polyester resins, used in surface coatings. There are many types, varying from very slow to very fast curing. Curing Melamine-formaldehyde can be cured by heating, which induces dehydration and crosslinking. The crosslinking can be carried out to a limited degree to give resins. Either the melamine-formaldehyde resins or melamine-formaldehyde "monomer" can be cured by treatment with any of several polyols. Applications Construction material The principal use of melamine resin is as the main constituent of high-pressure laminates, such as Formica and Arborite, and of laminate flooring.

Saws
A saw is a tool consisting of a tough blade, wire, or chain with a hard toothed edge. It is used to cut through material, very often wood, though sometimes metal or stone. The cut is made by placing the toothed edge against the material and moving it forcefully forth and less vigorously back or continuously forward. This force may be applied by hand, or powered by steam, water, electricity or other power source. An abrasive saw has a powered circular blade designed to cut through metal or ceramic. Terminology * Abrasive saw: A saw that cuts with an abrasive disc or band, rather than a toothed blade. * Back: the edge opposite the toothed edge. * Fleam: The angle of the faces of the teeth relative to a line perpendicular to the face of the saw. * Gullet: The valley between the points of the teeth. * Heel: The end closest to the handle. * Kerf: The narrow channel left behind by the saw and (relatedly) the measure of its width. The kerf depends on several factors: the width of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
