that seems to ensure that is helical-wedge rolling (HWR), a process that is a development of the helical rolling technique (HR). Helical rolling is widely used to produce balls for grinding media. The technique was invented in 1928 by an American named Hodge and con-sists in using a machine with skew-positioned rolls and guides [2].
Pater et al. (2018) proposed a new cross wedge rolling method for producing balls from heads of scrap railway rails. This method requires the use of a specially designed reversing mill which uses idle running to perform the first operation, i.e., rolling a bar from a rail head. Balls are formed from the bar in the second operation.
*) A Sendzimir mill is a mill with small diameter work rolls, each backed up by two rolls of larger diameter which are in turn jointly backed up by a cluster of three rolls. This mill configu-ration is often used for height-strength- and stainless steel. Factbox 1 ABB and rolling mills Footnote 1) A pass is one deformation step consisting of the
Introduction of skew rolling machine: Steel Ball Skew Rolling Machine is specially designed for the grinding steel balls of different materials such as medium carbon steel, alloy steel etc, which is widely used in the field of mines, gold, copper, bauxite, iron ore, aluminum ore, nonferrous non-ferrous metal ore, metallurgical and mining, cement, thermal power, flue gas desulfurization ...
Helical-wedge rolling is used on a large scale in the production of steel balls used on grinding media in ball mills [4]. Skew rolling technology produces balls 15-125 mm. The efficiency of such a process is very high, because it is possible to obtain part during one rotation of the rolls.

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. What's more, the tools can be used three times longer than air hammers. Learn More.
Cross wedge rolling (CWR) is also used to produce balls, yet only the full ones. The process consists of axial forming symmetric parts with wedge-shaped tools. The tools are mounted either on the rolls or on flat or concave plates of the roll-ing mill [2]. Also, there are numerous innovative manners for producing balls by helical rolling, developed

that balls can be produced by multi-wedge helical rolling. Key words: helical rolling, multi-wedge tool, ball, finite element method (FEM) INTRODUCTION Due to a huge demand for balls used in rolling bear-ings and ball mills for raw material grinding, extensive research has been undertaken to develop new efficient production methods.
Two cross-wedge rolling processes are modelled numerically using Simufact Forming. Numerical results are then verified by experiments performed on a flat wedge rolling mill. Results obtained with the two rolling methods are compared in terms of material fracture, force parameters, effective strain and thermal conditions during rolling.
This paper presents two rolling technologies: cross-wedge rolling (CWR) and helical-wedge rolling (HWR). The two rolling processes were compared using the example of rolling a ball stud forging. The technologies were modeled in the finite element model (FEM) environment. Calculations were performed …
The rolling process for forming ball studs was performed under laboratory conditions using the flat-wedge rolling mill as shown in Fig. 6. The tools were fixed in the work space of the machine as shown in Fig. 7. The machine's slide with the fixed upper tool moved with a velocity of 0.3 m/s. Force parameters in the rolling process were measured ...
Cross-wedge rolling is a process conducted mainly in hot forming conditions. Warm forming is a compromise between hot and cold forming. This paper presents the results of a comparative analysis of warm and hot rolling of ball-shaped pins. Rolling process was controlled in terms of energy consumption, load and abrasive wear of tools.
The paper presents a complete numerical model of a helical-wedge rolling process for producing balls. The model was designed in Finite Element Method (FEM)-based Forge NxT v.1.1 that enables the simulation of both forming and separating balls. A comparison of numerical results with experimental findings revealed a very high agreement in both …
