How do logs become planks? A large piece of log plank, how is it made

Log plank: Formed directly from logs, the width and length are limited by the size of the logs, and the specifications are not uniform, generally used for wooden floors, packing boxes, rough (original) style furniture, or as raw materials for further processing. In ancient times, when modern high-pressure bonding technology was not available, there were only two ways to obtain large wood panels

One is to find as large diameter as possible logs to cut, the cost is high, the quantity is small; The second is to use mortise and tenon.

Splicing small wooden boards, complex processing, easy to open and seam. Logs need to be properly dried and stress relieved to avoid warping and cracking in the future. The advantages are beautiful pattern, high strength, natural environmental protection and no formaldehyde release.

Finger jointed plates. A solid wood board made from multiple wooden planks spliced together.

The thickness of each board is the same as the thickness of the finished plank, and the upper and lower boards are no longer glued to the plywood. The amount of glue used in the finger joint board is very small, which is more environmentally friendly, and the wood grain is beautiful, the wood utilization rate and the cost are better than that of man-made boards.

High. It is mainly used for furniture and decoration projects.

Woodworking board: also known as large core board.

Wood core board is a man-made board made of outer veneer and intermediate glued spliced wood strips. The upper and lower veneers are obtained by rotary cutting or planing of logs, with a thickness of about 1mm, which is used to completely cover the board, provide transverse strength, and present an aesthetically pleasing wood grain. The spliced wooden strips in the middle are made of wood lines of equal length, width and thickness after drying, and the main function is to provide a certain thickness and strength for the board.

Woodworking board does not have high requirements for log materials, and can use logs of various materials and sizes, with a high utilization rate of wood and less formaldehyde release with less glue.

less, and to a certain extent has the characteristics of solid wood. <>

Plywood is a three-layer or multi-layer plate-like material made of wood segments that are rotary cut into veneer or cut into thin wood by wood planer, and then glued together with adhesive, usually with odd layers of veneer, and the fiber direction of adjacent layers of veneer is glued perpendicular to each other. The veneer on the surface can be made of high-quality wood with a beautiful wood grain, giving it a finish similar to that of a log plank. Plywood has a high utilization rate of wood, light weight, clear grain, high strength and not easy to deform, but the amount of glue used is large, and the formaldehyde release is large.

MDF, also known as fiberboard, is a man-made board made of wood fiber or other plant fibers using adhesive at high temperature and high pressure. The advantage is that the utilization rate of wood is very high, waste wood and other plant fibers can be used, the processing performance is good, the decoration is good, and it is mainly used in furniture manufacturing. The disadvantages are that the amount of glue used is large, the amount of formaldehyde release is large, the moisture resistance is poor, and the nail holding force is poor.

There are thick and thin logs, and if you want to make wide boards, you need to splic, or make thin parts, such as wooden frames, table legs, stool legs, mop rods, etc., of course, you also need to consider the cost depending on the wood. Using the stump to make a tea table is not only practical, but also ornamental, inseparable from the art of root carving, according to the size of the diameter of the root pile, it is best to use a cross-section, without affecting the appearance of the modeling, it should be cut in the place with the largest diameter, according to the needs of the shape to decide the support part of the stay, particleboard is also known as the crushed board, due to the different raw materials used, there are some other names, such as bagasse board, Ousong board. It is a man-made board made of wood or other lignocellulosic materials, which is glued under heat and pressure after the application of adhesive.

It is mainly used for furniture manufacturing and decoration materials, with better strength, more difficult processing, less glue and less formaldehyde release. <>

Fragments of wood, machined and combined.

Untie it with a band saw, then plane.

Logs are sawn into planks with a special saw Small planks used to be riveted with tenons or tenons in ancient times, but now they are mostly glued together.

Electric belt saw. It is a toothed saw made of steel belt, welded into a ring joint, like a circle formed by two U sets. The height of the two U-shapes is more than one person, and even the thickest logs can be processed, and they can be driven by a motor for high-speed operation.

The log is fixed to the chute for horizontal movement, and a piece of ...... is sawn off by a band sawIn this way, the logs are sawn into planks of the desired thickness.

In the Workbench page, you can use the shift key on the keyboard + the left button on the mouse to make no more than 1 set of logs (all items) into planks at once.

There are also some useful keys:

Hover at the hotbar item and shift+left click to place the hotbar item into the inventory.

Hover at an item in the hotbar (inventory) and right-click to split the item into two parts (odd numbers cannot be divided equally).

Computer? Put the logs in the crafting, don't point them one by one, press shift and click on them, and they all become planks.

Put the logs in the crafting, don't point them one by one, press shift and click on them, and they all turn into planks for good luck.

Hold down shiftRight-click. You can't replace all the logs with planks.

Use a saw, do you use other tools to cut wood?

I also want to know, ah, I've seen it, I've played it; But I don't know what it's called. I want to buy it and start a wood processing factory.

First, it is broken down into small planks of the same size and thickness, and then finger seams are made at both ends of the board, and the finger joints are spliced together under high pressure with glue to form large boards, and then cut and workmanship according to different products.

You also asked about the very hard situation, the density of the wood determines its softness and hardness, generally choose to make furniture wood will choose to do hard, such as ash, rubberwood, hard oak and other common, mahogany furniture hardness is greater.

Timber bending method:

1. In general, bend the plank (wood), yesAfter the wood is softened, it is bent into the desired curved shape under the action of the bending moment and allowed to dry and set。Wood cannot be softened by heating by fire, but it can be softened by steam. The bending properties of wood vary greatly from tree species to species, even in different parts of the same tree species.

2. Solid wood bending forming is a chipless solid wood forming processing process, which can be divided into three stages:Plasticizing (softening), bending, and shaping (drying and cooling in the model frame).。The timber is first planed into square timber and then precisely cut to curved lengths.

In order to achieve bendability, the wood (i.e. the workpiece) must be softened by light, which is manifested by the effects of temperature and humidity.

At present, the traditional softening method is the cooking method, which uses moisture and heat as softeners for wood。Generally, the prepared wood is softened for a period of time in steam under certain conditions (pressure, temperature, humidity), and the length of time is related to the moisture content of the wood, the tree species and the thickness of the wood. The most suitable moisture content for wood bending is the moisture content of the saturation point of wood fiber, that is, 20 -30, when the strength of wood is the smallest, and the deformation that can be produced is the largest.

4. The plasticity of wood is very small under normal conditions, and the convex surface is directly bent to form a convex surface that is compressed by tensile concave surface, and when the tensile strain reaches about 1%, the tensile surface fiber is broken and destroyed, and the compression surface produces wrinkles, so it is difficult to obtain the required bending curvature radius.

Large quantities of wood are bent and bending is required mechanically. It can adopt mechanical, pneumatic, hydraulic transmission, etc.

How do you bend a plank? Just put it in the punch and you're good to go!
