Veneer knives

Veneer cutting knives are used in the woodworking industry to obtain sliced veneer from wood, mainly valuable species, which serves as a facing material used in furniture production and construction. Veneer knives are designed for finishing cutting of sliced and peeled veneer 0.6 - 0.8 mm thick along and across the grain on special industrial shears for chopping veneer tape into sheets of a certain format and trimming veneer pieces. With their help, veneer is cut into sheets of the required size. Knives are made of two-layer steel "Compound" of our own production with a body made of ST3 steel, and an alloy layer of WD1 and DIN1.2510 steel with a hardness of 55 ... 60 HRC, or from German steels with a cutting layer hardness of 58 ... 60 HRC. The average service life of a knife before resharpening is: - when cutting veneer along the grain: 32 hours; - when cutting veneer across the grain: 7 hours The average service life of a knife when planing mahogany or beech veneer with a removed layer thickness of 0.6-0.8 mm and a feed rate of 16 to 22 strokes per minute is from 1 to 8 hours, depending on the hardness of the wood. Standard knives are manufactured with a length of L = 900-3100 mm, a width of B = 115 and 150 mm and a thickness of S = 9 and 15 mm according to TU 14-19-102-90, according to the dimensions given in the table. The knives given in the table can, at the customer's request, be manufactured with increased precision.
