Wood veneer for furniture

The uses of wood veneer in the furniture industry is very common. The price of wood is going to be more and more expensive. The price of wood species with beautiful grain such as: teak, cherry, mahogany, walnut, rosewood, etc are not only expensive but also become difficult to be outsourced. Many peoples are talking about keeping the wood and forest to save the earth. Moreover the global warming issues are very strong and popular and influence many aspect in human life. This condition has made strong pressure to the furniture industries. The woodworking industry have to do action to save the wood as its main raw material. Since that, more furniture factories prefer to use the wood veneer to make panels, board replacing the solid wood. 
The veneer technology actually actually is not a really new technology, it was already known and developed since the end of 19 century. And now the veneer technology is already very advanced to meet the requirement of furniture industries. Veneer is wood log that is sliced in to form very thin sheet layer, The common thickness is usually between 0.2 mm to 1 mm. The other thickness are also available but must be special ordered. Wood veneer is usually made of from premium wood that has beautiful grain, but most of commercial wood now are also available in the veneer form.  Veneer is used to make the wood panels with special grain and looked such as: crotch, burl, swirl, etc.  The veneer has some advantages compared with wood; his price is considered cheaper, the flexibility in arrangement and also the better stability.
Veneer is attached to the core panel to make board panel. The common core for veneer are : m.d.f., particle board, or laminated wood from the wood with cheap price. Sengon wood, or jabon wood are the "cheap" wood that can be used as veneer core. M.d.f. (medium density fiberboard) is processed wood material made from wood pieces cooked in a tank (digester), and then this pulp is passed through a roller to form a board with a certain thickness and sizes. The particle board are pieces of wood that was ground and then mixed with glue and pressed to produce board sheets with a certain thickness and sizes.
The veneers can be arranged to form a certain pattern and produce a more attractive appearance. With many different slicing techniques, veneer is be able to produce many patterns to varied wood looked. This veneer can be more flexible and can be arranged with more varies by optimizing the patterns of slicing and the type of veneer. With a good lamination, the veneer is also more stable than a solid wood board. Wood board has more pores than veneer on m.d.f.; so it has higher risk to the wood movement caused by the changes of temperature and moisture content. Veneer can also solve problems at the difficulties to get a long and wide wood. 
With his  advantages, the veneer is used more to make furniture, especially to make wide, long panels. The furniture industry has replaced the use of wood panels to veneer panels in the manufacture of boards, especially for indoor furniture. For outdoor furniture, the veneer usage is still limited because its not strong enough to withstand the outside weather. The veneered panel for exterior must be made with special glue and special core which could be more expensive than the solid wood.

How wood is sliced to make veneer?

The wood can be sliced in some different way and it will determined the veneer looked. There 5 ways of cutting veneer that commonly used. They are: rotary slicing, flat slicing, quarter slicing, half round slicing and rift cut slicing. 


rotay wood veneer



1. Rotary veneer
Timber is mounted in a certain position and then be rotated so that the blade is driven to cut wood from the outside.

flat slicing wood veneer



2. Flat slicing
Timber is mounted on a certain position, then be moved to so that the knife cut parallel to the mid line of wood.

quarte slicing





3. Quarter slicing
Timber is mounted on certain positions and then move the knife to cut at an certain angle.

half round veneer






4. Half round slicing

Variation of the rotary where timber is fitted with a certain distance from the center of the circle rotation

rif cut wood veneer




5. Rift cut slicing
More variation of the rotary slicing, timber is mounted on a certain position, then wood is cut into a quarter and moved around to the knife
