Opening is a part of the attention of the owner of mahogany furniture. The good wood should not only be classified according to its straightness and thickness, but also according to the needs of furniture production, considering the texture, length and thickness of the plate when the material is opened. This is the time to do the most reasonable use of materials. However, another factor that has a huge effect on material saving - sawing is often overlooked.
Because of the furniture, the thick and thick logs have to be broken into squares, and then the materials are broken into sheets, and the material loss in the sawing of the mahogany is inevitable. The thickness of the band saw or circular saw blade and the size of the sawing road directly affect the yield of the mahogany. For example, a square with a thickness of 200 mm should be opened into 20 plates. Ideally, according to the sawing 20 times, the sawing path is 2.5 mm and the thickness loss is 50 mm, that is, the final plate has an effective thickness of 150 mm and a yield of 75%. If the sawing path is accurate to 1.5 mm, the thickness loss is only 30 mm, that is, the final sheet has an effective thickness of 170 mm and a yield of 85%. Compared with the two, the sawing accuracy is increased by 1 mm and the yield is increased by 10%.
Increasing the yield of 10% means saving a considerable amount of money in the mahogany furniture industry, where materials are scarce and expensive. For the big fruit rosewood, one ton is temporarily calculated at 28,000 yuan, 10% is equal to 2800 yuan, 100 tons of wood can be saved, and it can save 280,000 yuan; then take about 200,000 tons of one ton of Sian rosewood, 10% It is equivalent to saving 20,000 yuan, 100 tons to open, you can save 2 million yuan. In this way, for the more high-end, more expensive old materials, good materials, the value of sawing accuracy increased by 1 mm, it is even more incredible. In fact, the meaning and value of this 1 mm is far more than that.
The improved precision of the sawing surface makes the surface of the sawn board smoother, smoother and more delicate. It can be directly used to make furniture by grinding with fine sandpaper, thus saving the wood loss of planing (usually planing). The thickness is 0.3-0.5 mm). This not only saves labor costs, but also further increases the yield by 1% to 2%. In short, mahogany furniture companies must not underestimate the precision of the sawing road by 1 mm. One year, it saves money for the bosses to buy wood money, you can buy a luxury villa!
Redwood raw material cutting: saving 2 million in precision 1 mm
Abstract In the mahogany furniture industry, the band saw used for cutting is usually 2.5 mm, while the current finer sawing path is only 1.5 mm. Although the accuracy is only increased by 1 mm, the material saved is not a small amount. However, the market value of this technological innovation has not yet been obtained by industry people...
In the mahogany furniture industry, the band saw used for cutting, the sawing road is usually 2.5 mm, and the current finer sawing path is only 1.5 mm. Although the accuracy is only increased by 1 mm, the material saved is not a small amount. However, the market value of this technological innovation has not received the general attention and attention of the industry. To this end, this magazine specifically calculates the account for the boss of the mahogany furniture company, and makes a quantitative analysis of the value of this 1 mm for reference.
