Finger joints (also known as comb joints) are a wood joint technique that gets its name from the cross-section looking like interlocking fingers. The fingers are made by cutting complementing triangles or rectangles in two pieces of wood that are glued together to form a complete piece. It is one of the strongest woodworking joint techniques which creates greater strength in the joint than the stud itself.
Stirling Machinery has the right Finger Jointer system for your operation, with applications ranging from bespoke furniture making to high scale sawmills and engineered products. Our machines have customisable levels of automation for either manual, semi-automatic or fully automatic operation.
Finger jointers, often referred to as finger joint machines or finger jointing systems, are specialized woodworking tools designed to create strong and precise interlocking joints between wooden pieces. These joints, also known as finger joints or box joints, are characterized by their closely spaced, alternating projections and notches that resemble interlocking fingers when fitted together. Finger jointers are widely used in woodworking industries, furniture manufacturing, cabinetry, and construction to produce high-quality, stable, and durable connections between wooden components.
The primary purpose of finger jointing is to extend the length 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 mesh seamlessly with corresponding fingers on another board, creating a robust joint that distributes weight, stress, and load evenly across the jointed surface.
Finger jointers offer several advantages that make them essential tools in woodworking operations. Their precision and uniformity lead to joints that are not only visually appealing but also capable of withstanding significant stress without weakening over time. This makes them ideal for applications where stability and durability are crucial, such as in load-bearing structures or heavy-duty furniture pieces. Finger jointers are capable of creating joints in a variety of wood species, from hardwoods to softwoods, providing flexibility in material selection without compromising joint integrity. Finger jointing increases the yield of usable wood from raw timber, reducing waste and contributing to sustainable forestry practices. With advancements in technology, modern finger jointers incorporate automation and computerized controls, allowing for faster production and higher levels of precision.
Finger jointers play a pivotal role in woodworking industries, offering an efficient, cost-effective, and environmentally friendly solution for creating robust and visually pleasing interlocking joints that enhance the strength and longevity of wooden structures and products.
