rolling.13 2. Engineering Background of CWR Technique 2.1. CWR Machines CWR technique, as the method of producing shaft, has been studied retroactively in the 19th century. The patent for a CWR mill was rstly led by Lebek in 1879.
Among the cross rolling technologies, the one mostly applied in the forging industry is the cross-wedge rolling CWR, which is used to form components such as stepped axles and shafts, as well as .

The forming wedge is characterized by the angles 20176 and 9.5176. The side surfaces of the wedges have technological cuts, aiming to hinder the occurrence of uncontrollable slipping.
This study investigated the effect of grain size on the cross wedge rolling of micro copper rod. Annealing techniques and equal channel angular extrusion were employed to refine the grains of copper, after which the treated copper was machined to prepare the cylindrical billets with 1 mm diameter for conducting experiments.

The rolling process experiences many other profile problems caused for example by the work rolls wear off or damage and it is impertinent to follow up all possible causes changing the transverse strip profile shape continuously to ensure the optimal roll usage.
Cross wedge rolling machine is widely used in forging connecting rod, crankshaft, camshaft, auto parts, etc., replace air hammer with the advantage of high productivity, efficiency, high rate of finished products. Whats more, the tools can be used three times longer than air hammers.
Laminated shafts are often used as alternatives to elemental metal shafts, which are prone to corrosion and wear. However, manufacturing laminated shafts is difficult. In this paper, a laminated shaft production method involving cross-wedge rolling was proposed. The cross-wedge rolling of 42CrMoQ235 laminated shafts was numerically simulated using ANSYSLS-DYNA software.

FENN Rolling Mill machines are available in both 2Hi and 4Hi roll configurations, and mills may be either work roll driven, back-up roll driven, or a combination of both. On one end of the spectrum, 4Hi Rolling Mills with work rolls are offered as small as .500quot 12.7mm in diameter. Ball mill Wikipedia.
2017-1-24ensp0183ensp2.2. Cross wedge rolling technology The paper proposes the idea of the cross wedge rolling of the spiral shaft parts. As shown in Fig. 2, the principle is that the upper and bottom molds move oppositely, making the billet rotation. Under the hole of the molds, the billet is formed with different shaft partsHu et al, 2004.
2019-9-6ensp0183enspCross-wedge rolling CWR is a technology used mainly to form axisymmetrical products 1. Tools with a polygonal cycloid prole, however, provide the possibility to form products with non-axisymmetric e.g., square, triangular, oval cross-sections from circular cross-section billets 2.
in accordance with the above concept, a flat-wedge rolling mill was designed and constructed. The results demonstrate that the machine can be used to produce balls from heads of scrap railway rails. Keywords forgings of balls, rolling, cross-wedge rolling mill 1.
