Band saws for metal

A bimetal blade A real breakthrough in ribbon cutting technologies was the development and production of bimetal bandsaw blades, specific volume in band sawing, the ordinary and special materials is about 90%. Choosing the correct geometric parameters of the tool - a necessary and important stage in the development of band sawing. Fundamental aspects when choosing the size of the drink, the shape and steps of the teeth are: You need to use the saw only for the length and width of the canvas, specified in the technical passport of the band saw. Under other equal conditions and opportunities, use saw blades with a greater width of the fabric, which positively affects the quality of cut and stability of the process of sawing. When cutting soft materials, use saw blades with a large pitch and flute volume. Cutting of solid materials requires the use of saws with lots of teeth for a better distribution of load reduction on the tooth. In the General recommendations to adhere to the following requirements: Materials machinability the normal Minimum number of teeth on the RES - 3 Maximum number - 24 is the Optimal number - 6/12 Materials with increased hardness of the Minimum number of teeth on the RES - 6 the Maximum number is 36, the Optimal number -12/24 These recommendations are based on the features of band saw cutting mechanism. When there are too few teeth in cutting the load on each tooth can be excessive and lead to failure. When the number of teeth is greater than the allowable load on each tooth is small, but increases the total cutting force, which can lead to the rupture of perezarazhenie of blade. Vitality drink, which is contained in various tables of the cutting conditions in practice can be achieved only under a number of conditions: Full compliance of the norms of accuracy and rigidity of the band saw its passport characteristics. Properly selected cutting conditions for the corresponding material and shape of workpiece, cutting conditions, quality and size of the band saw; Properly selected coolant, its concentration, and flow conditions in the cutting zone.
