Centerless lathes and straightening and calendering machines for a wide range of applications
Our company is a manufacturer of centreless lathes and straightening and calendering machines with advanced technology, which can meet the different requirements of different users in terms of processed materials and precision as well as the degree of ease of use, with the following advantages:
Meets environmental requirements. The traditional drawing and wire drawing process requires pickling, seriously polluting the environment, and has been subject to strict production restrictions by the environmental protection department, and the use of pickling has been explicitly banned in some areas of China. At the same time, a large number of annual and gradually increasing sewage charges, which greatly increases the difficulty and cost of production, while the centerless machine tool is to remove the metal oxide layer by turning, will not produce any environmental pollution, in full compliance with the requirements of green, environmental protection, recycling production.
It meets the requirements of no cracks and no internal damage. Traditional drawing and wire drawing cannot avoid surface and internal cracks due to their own processes, which can cause internal damage to the processed parts and make the workpiece elongated with defects within a certain range, which does not meet the requirements of modern metal processing for high strength, high density, no internal damage and high fatigue resistance. In western developed countries the drawing and drawing process has long been replaced by the more advanced centreless turning process. Especially for enterprises that need to export, due to the strict regulations of foreign countries for product defects, and the defects caused by the drawing process is very easy to trigger trade losses, the use of centreless turning process is imperative.
Centerless lathes have unique advantages in processing extra-long bars (including infinitely long discs). Ordinary lathes can only process shorter bars, and when processing long materials, it is necessary to clamp and align the long bars several times, and it is difficult to ensure the coaxiality and roundness of the processed bars, and there is always taper. On the other hand, no matter how long or how many bars are continuously processed by the centreless lathe, as only one tool setting is required to ensure the high precision processing of all the gang dishes, and as it is fundamentally different from the processing form of ordinary lathes, all the disadvantages of ordinary lathes are completely improved in the processing of long materials.
The iron scraps withdrawn from the centerless lathe can all be recycled, and the unit price can be bought at least half of the finished steel, which can substantially increase the factory profit, while the powder generation after the centerless grinder face and diamond fragments do not have much recycling value.
The straightening and calendering machine replaces the semi-finish grinding of the centreless grinder for precision straightening and calendering, which does not produce powder scrap but also improves production efficiency.
Compared to traditional straightening machines (straighteners/straighteners) the straightening and calendering machine not only has a high straightening speed (up to 10 metres per minute or more) and high precision, but also achieves a surface finish similar to that of electroplating.
Wide range of application. Various metal materials can be processed: stainless steel, bearing steel, spring steel, tool steel, structural steel, alloy steel, non-quenched steel, easy-to-cut steel, valve steel, gear steel and various non-ferrous metals (e.g. titanium alloy, magnesium alloy, steel and aluminium, etc.). It is widely used in bright shaft, machinery manufacturing, vehicle production, electrical instrumentation, bearing, spring manufacturing, hydraulic and pneumatic components, light industry machinery, steel pipes, cutting tools, petroleum, electric power, bridges, engineering machinery and other industries (e.g. goring columns, lola shafts, piston rods, shafts, pins, light and silk bars, mandrels, oil drilling rods, slender bolts, steel cables, springs, pipe billets, etc.).
