Our fabricators utilize the cold pilger process daily to make precision tubes from our titanium. Pilgered thin wall tubing provides improved mechanical properties and accurate dimensional tolerances. The pilgering machine is designed to make large reductions in the tube cross sectional area in a single pass.

Comparing the cold pilger mills in accordance with the present invention as explained above with the conventional cold pilger mill as shown in FIG. 2, it will be noted that the mill of the present invention requires the rotational angle detector 74, the driving pulse motors 76, 78, 80 and 82, the controller 72, and, in the second embodiment

For manufacturing of tooling for cold pilger rolling it is required a special equipment. Mandrels and support rails are manufactured mostly at standard cylindrical and surface grinding machines with CNC after pre-turning. To manufacture dies of variable cross-section is possible at specialized machines only.

The

The cold pilger process is a common method of finishing seamless stainless steel hollows. Many aspects of the pilgering process influence machine productivity and finished tube quality. This article discusses an analysis done on two different tool die designs and their effects on tube quality and machine productivity.

Cold pilgering has been around for many years since being patented in the US in 1896. Cold pilger mill machines perform work on preexisting tubes produced by means of cast, welding or extrusion. Pilgered tube metal alloys include aluminum, copper, gold, silver, stainless steels, titanium, zirconium and a host of many other special materials

Pilger Mill PM

Pilger Mill Cold pilger mills are used for the reduction of tubular products of all ferrous and non-ferrous metals. Beside the classic applications for bearing tubes, stainless steel tubes and copper tubes, tubes of nickel-based alloys, high-strength special metals, titanium and zirconium alloys are also produced.

Cold pilger mill machines perform work on preexisting tubes produced by means of cast, welding or extrusion. Pilgered tube metal alloys include aluminum, copper, gold, silver, stainless steels, titanium, zirconium and a host of many other special materials that are derived from various metal alloys.

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.
