Efficient And Versatile Finger Joint Machine For Splicing Comb Tenons Of Short Woods

finger joint machine works as a wood working device that is used to design a joints around two some timber that interlock together like fingertips. This joint is regarded as a finger joint or just a package joint, and is particularly commonly used in a range of wood working initiatives, that include floor coverings, furnishings, and cabinetry.

The operation of producing a finger joint includes slicing a number of corresponding rectangle slots or “hands and fingers” in to the last part of each sheet of wooden. These hands and fingers are then interlocked in unison to generate a protected, interlocking joint this is much stronger and more firm than old school butt bones.

Finger joint System for Woodworking

Finger joints, also known as comb joints, are a popular woodworking technique where two pieces of wood are joined together by interlocking fingers, resembling the shape of interlocked fingers. These fingers are created by cutting complementary triangles or rectangles in the wood pieces, which are then glued together to form a solid joint. This method is recognized for its exceptional strength, surpassing that of the individual pieces of wood.

ZZCHRYSO offers a range of Finger Jointer systems suitable for various woodworking operations, whether it’s crafting customized furniture or working in large-scale sawmills and engineered product manufacturing. Our machines provide customizable levels of automation, allowing for manual, semi-automatic, or fully automatic operation, tailored to your specific needs.

What is A Finger Jointer?

Finger jointers, also referred to as finger joint machines or finger jointing systems, are specialized woodworking tools designed to create robust and precise interlocking joints between wooden pieces. These joints, commonly known as finger joints or box joints, feature closely spaced projections and notches that resemble interlocking fingers when assembled. Finger jointers find extensive use in woodworking industries, furniture production, cabinetry, and construction, enabling the creation of high-quality, stable, and durable connections between wooden components.

Primary Purpose of Finger Jointing

The primary purpose of finger jointing is to maximize the utilization of available timber by efficiently joining shorter sections, resulting in longer, continuous pieces of wood that maintain the structural integrity of solid lumber. The process involves shaping and cutting the ends of wooden boards into uniform fingers that seamlessly interlock with corresponding fingers on another board, creating a sturdy joint that evenly distributes weight, stress, and load across the jointed surface.

Advantages of Using Finger Joint Machine

  • Boosted firmness and force: Finger important joints put together a a great deal even more and more substantial balanced joint than vintage butt joints, which makes them appropriate for purposes exactly where robustness is really top priority.
  • Improved upon overall look: Finger joint capsules are usually contemplated a great deal more attractive than other sorts of joint capsules, as they start to provide a easy, interlocking design which will help the overall look with the complete service.
  • Lower trash: Finger joint products are capable of establishing outlets with very small waste matter, as a hands and fingers are correctly chop to fit jointly without the unwanted resource
  • Heightened efficiency: Finger joint machines can drastically increase the speed of the procedure of crafting important joints, granting woodworkers in order to complete undertakings a lot more efficiently and quickly.

Finger joined lumber

Finger joined products are manufactured by taking shorter pieces of kiln-dried lumber, machining a ‘finger’ profile in each end of the short-length pieces, adding an appropriate structural adhesive, and end-gluing the pieces together to make a longer length piece of lumber. The length of a finger joined lumber is not limited by the length of the log. In fact, the manufacturing process can result in the production of joists and rafters in lengths of 12 m (40 ft) or more. The process of finger joining is also used within the manufacturing process for several other engineered wood products, including glued-laminated timber and wood I-joists. The specific term “fingerjoined lumber” applies to dimension lumber that contains finger joints.

Finger joining derives greater value from the forest resource by using short length pieces of lower grade lumber as input for the manufacture of a value-added engineered wood product. The finger joining process utilizes short off cut pieces of lumber and results in more efficient use of the harvested wood fibre. Finger joined lumber can be manufactured from any commercial species or species group.

Advantages of finger joined lumber

Finger joined lumber is an engineered wood product that is desirable for several reasons:
2.Dimensional stability
3.Interchangeability with non-fingerjointed lumber
4.Highly efficient use of wood fibre
The design and performance advantages of this engineered wood product are its straightness and dimensional stability. The straightness and dimensional stability of finger joined lumber is a result of short length pieces of lumber, consisting of relatively straight grain and fewer natural defects, being combined with one another to form a longer length piece of lumber. The grain pattern along finger joined lumber becomes non-uniform and random by attaching many short
pieces together. This results in finger joined lumber being less prone to warping than solid sawn lumber. The finger joining process also results in the reduction or removal of strength reducing defects, producing a structural wood product with less variable engineering properties than solid sawn dimensional lumber.

The most common use of finger-joined lumber is as studs in shearwalls and vertical load bearing walls. The most important factor for studs is straightness. Finger joined studs will stay straighter than solid sawn dimensional lumber studs when subjected to changes in temperature and humidity. This feature results in significant benefits to the builder and homeowner including a superior building, the elimination of nail pops in drywall and other problems related to dimensional changes. This also makes finger joined lumber an ideal candidate for interior nonload bearing partitions.
