to a polycrystalline mill product some of the single crystal aniso-tropic mechanical behaviour. If the mill product is a finished structural component, this mechanical anisotropy has to be taken into account in design, since it can either seriously limit or increase the allowable design stre-ses.

Cold pilgering is a longitudinal cold-rolling process that reduces the diameter and wall thickness of metal tubes in one process step. Depending on the material, the cold pilger process achieves cross-sectional reductions of more than 90 percent in a single working cycle. Figure 1 shows the principle of the cold pilger process.
The No. 5R bearing supports the high-pressure turbine rotor (HPTR) at its forward shaft. The D and E sump houses the No. 6R and No. 7R bearings. The No. 6R bearing supports the forward end of the low-pressure turbine rotor (LPTR) shaft. The No. 7R bearing supports the aft end of LPTR shaft and the balance piston system.

Abstract. The paper presents the results of an experiment and numerical simulation in a new pilger tube cold-rolling process, in which the rolling stand is stationary and the rolled tube is placed on a slide and between the rollers. The experiment was conducted in a laboratory pilger mill operating according to a new concept of rolling.
The Slitter, commonly referred to as Slitter Rewinder, is a primary machine used in the conversion of steel, alluminium material. Designed to convert a wide roll of material into several thinner rolls, the slitter starts by unwinding a master or mill roll, continues by slitting the unwound material into various widths, and finally completes the process by rewinding the slit material …

The conversion of the rolling mill to a pilger mill consisted of removing the mechanical linkages that connected the gear motors to the roll dies. The pilger mill system was designed to use index-able servo motors that are connected to the large drive rolls directly. This design allows for more flexibility in the degree and speed of die rotation.

A three-roll type HPTR rolling mill was used to manufacture ODS steel claddings. Cold rolling passes and intermediate annealing were repeated until reaching the final geometry: 10.73mm external diameter and 500µm thick.
The HPTR cold-rolling process was used by both JNC and CEA, but the applied fabrication routes included different cross-section reduction ratios, number of passes and intermediate heat treatments. The manufactured claddings exhibited an isotropic grain structure and equivalent tensile strength in the longitudinal and transverse directions.
Today the tubes made by HPTR mills are used in a variety of end use products. EZTM, a Russian company and manufacturer of HPTR mills, mentions "space and aircraft engineering, shipbuilding, petrochemical and chemical industries, and other sectors of machinery building" as fields that commonly use tubes from its mills.
