What Steel Saw Blades
Today, it is probably difficult to find a person who at least once in his life has not encountered sawing wood and its derivatives. Agree that in the construction or repair, the manufacture of windows or doors, furniture or stairs, in the country and the household, the most popular tool is circular saws.Manufacturers of circular saws are quite widely represented on the Ukrainian market, from world brands to domestic manufacturers. This article will discuss the advanced technical solutions of the Italian company POZZA S.P.A, which allowed the brand circular saws freud® to take a leading position in the world both in the number of saws produced and sold, and in the ratio “price. Quality”.
Features and technological advantages
Freud® uses only the finest grades of tool steel from Germany with a hardness of over 42 HRC to manufacture the enclosures of its circular saws. This gives the saw body excellent rigidity and contributes to reliability during the sawing process. At the same time, steel is subject to mandatory rigid entry control.Cutting of sheet steel is performed on automatic fishing lines by laser cutting. This completely eliminates the residual stress at the edge. Laser-cut compensation slots not only effectively dissipate stresses from heating and centrifugal expansion of the metal of the saw body, but also significantly affect noise reduction. In addition, the use of this method allows you to freely and flexibly design the design of the body of the circular saw. And the use of the above-mentioned special “silent” slots in the design of the saw body allows you to reduce noise and vibration by 40%. During the manufacturing process, the saw bodies are subjected to additional tension using a rolling of the saw body. This gives increased stability during the cut. In addition, all the saws freud® undergo dynamic balancing and control of beats, both in radial and axial directions. Particular attention is paid to the mounting holes of circular saws. Special machining and dimensional control ensure absolute precision in tool rotation.Own production of hard alloy allows freud® to control 100% quality of HM solders already at the stage of their production. Few companies in the world have similar high-tech facilities. This mainly allowed the manufacturer to select the properties of the alloy depending on the purpose of the tool. For teeth of circular saws freud® uses a hard alloy only with a particularly fine-grained structure and the addition of titanium. This combination gives maximum hardness, while maintaining the necessary elasticity. The teeth are soldered to the body only using a silver-copper-silver sandwich. Silver contributes to the deep penetration of solder into the joined surfaces, and copper creates a damping layer that protects the saw teeth from destruction due to impacts during operation. Sharpening angles freud® picks up specially depending on the processed material. A special form of soldering allows you to increase the number of regrinds.It should also be noted that the entire manufacturing process of circular saws is subject to rigorous quality control. A streamlined production process system, as well as a control system for personnel management processes and a sales network, allowed the company FREUD POZZA S.P.A to receive the certificate of compliance with the international standard ISO 9002 one of the very first in the industry. That is why the company has taken a tough stance in the fight against various kinds of fakes of its products. The entire instrument, besides an individual code by which it can be traced, is laser-marked, and every half a year the company introduces new packaging elements.All these steps could not fail to bring the Italian company FREUD POZZA S.P.A to a leading position in the world in the production and sale of their products. Today, the company specializes in producing a wide range of carbide tipped saw blades. Last year, this amounted to approximately 16 thousand saws per day. By gamma or type of application, circular saws can be conditionally divided into several groups.
Universal saws: circular saws designed for longitudinal and transverse cutting of soft and hard wood (LU2A, LU1H).Miter Saws: circular saws designed for cutting across the fibers of hard and soft rocks (LU2B, LU2D, LU2C).Saws for multi-saws: circular saws designed for longitudinal sawing of soft and hard wood; come with scoring knives (LM01-LM07) and without them (LU1C, LU1D); with standard or reduced cut thickness (LM08).Saws for cutting chipboard, laminate and plywood: circular saws designed for cutting chipboard, MDF, laminates on machines with scoring unit (LU3D) or without it (LU3E), but with a negative rake angle.Scoring Saws: circular saws intended for use in addition to the main saws when cutting panels lined on both sides to avoid chips on the lower surface of the processed material; used on machines with the ability to adjust the cutting unit in height (LI25M) and without it (LI16M).
Saws for saw centers: circular saws designed for cutting laminated chipboard and MDF both on one sheet and in a package; the tooth shape can be alternately chamfered (LSA) or alternating straight and trapezoidal (LSB).Saws for cutting non-ferrous metals and plastic: circular saws designed for cutting profiles of aluminum and other non-ferrous metals (LU5A, LU5B), with a negative sharpening angle (LU5D), steel profiles (LU6A) and plastic (LU4A, LU4B).Pro series saws: circular saws for hand tools, designed for both longitudinal and transverse sawing wood on hand tools.
