MANUFACTURE OF SHAFT FROM STAINLESS STEEL
Shafts are cylindrical parts used to transmit torque in equipment for production purposes, in transport and other mechanisms where there is rotation. Shafts vary in size, weight, material of manufacture and shape. Classification of shafts Depending on its geometric axis, the shafts are straight, flexible, and bent (eccentric). The form distinguishes between smooth, hollow and stepped shafts. The shafts come with a channel along the axis (hollow) and cast. They are made of the most durable steel grades, because these parts have to withstand heavy loads and work in an aggressive environment. To improve performance, the shafts are subjected to heat treatment. Spheres of application of shafts from stainless steel Shafts are important parts of machines and mechanisms, without them it is difficult to imagine the operation of any industrial equipment. Shafts are needed wherever there is rotation (in rotating mechanisms and in transport). At us you can order shafts from stainless steel grades for any technical tasks. Shaft production Stainless steel shafts can be manufactured both according to the state standard, and according to individual drawings and mock-ups. Stages of production of shafts: 1. Design and construction. 2. Turning and boring of blanks on a lathe with numerical control. 3. Milling grooves and grooves. 4. Finish grinding. 5. Dynamic balancing. 6. Application of a protective coating. The shafts, which are intended for use in an aggressive environment, are made of corrosion-resistant steel grades. The first stage of the production of shafts is the turning of blanks on CNC lathes and precision borstands, so that products of even larger diameters can be easily processed from the outside and from the inside. Further, depending on the type of shaft, welding of its individual elements can be carried out. After grooving the grooves, the shaft is ground, which ensures dimensional accuracy. Measurement of shaft sizes is carried out by modern methods using a laser. Balancing of shafts At this stage of production, the quality of the shafts is checked by dynamic balancing. After all, if the shaft is made even with a small defect, then during the transfer of energy there will be large losses, and equipment will malfunction. Application of protective coating and heat treatment of shafts If the shaft is to be used in an aggressive environment (for example, acids, alkalis and salts will act on it), the product is subjected to additional corrosion protection in the form of an electroplating coating. And to increase the strength and wear resistance, the shafts are subjected to heat treatment. In our center of precision processing, you can order stainless steel shafts of grades: 1. AISI 304. Steel is acid-fast and can withstand a sharp temperature rise of up to 700 degrees Celsius. 2. AISI 316. The steel is resistant to corrosion, aggressive environment and high temperature due to the presence of molybdenum (2.5%). 3. AISI 321. The steel contains a lot of nickel and almost 1% of titanium, is heat-resistant and heat-resistant (suitable for operating conditions 600-800 ° C). 4. 08X13. The steel is corrosion-resistant and heat-resistant, suitable for operation at temperatures up to +580 ° C. 5. 12X18H10. Steel chrome-nickel, corrosion-resistant construction. 6. 14X17H2. The steel is corrosion-resistant, heat-resistant. 7. 08H18N10T. The steel is resistant to corrosion and high temperature.
