— It's pretty easy with a mill. No jig is needed. Posted: 11/19/2019 11:52:19 PM EDT [#10] Quote History. Quoted: I have done a few as a manufacture and you really don't need a jig to do one correctly, once you do one, they are really easy to do. A drawing with the correct specifications and a manual mill with DRO's it is a piece of cake to do one.

Abstract: THE COLD rolling of steel strip on tandem mills requires the measurement and control of tension in the strip, and to meet this requirement the tensiometer herein described has been developed. The tensiometer produces a continuous indication of the tension in the strip during the rolling operation, and functions in connection with auxiliary control …
The empirical research took place at a hot strip mill. As a result, the 3D ground non-circular geometry of the backup rolls considerably reduced the rolling force variation. Key words: non-circular grinding, rolling mill, backup roll, rolling force variation. 1. INTRODUCTION Contemporary steel mills are operating on a global market and the ...
found in multi-cluster cold rolling mills. Very often, mill maintenance teams are "refurbishing" the bearings themselves by regrinding the outer diameter. However, there is more hidden behind the thick outer rings, and remanufacturing is much more than grinding of outer diameters. Figure 10. Example Cassette with Backing Bearings.
Jigs position and fix products in place, allowing for machining along guides, inspection of machining accuracy, saving of labor and power to reduce costs, improve productivity, …
