Abstract

1462453 Sizing bores; drawing CHABAS & BESSON SA 24 July 1974 [11 Sept 1973] 32619/74 Addition to 1345802 Headings B3H and B3Q [Also in Division F2] In a method of calibrating the inner surface of a tube as described in Specification 1,345,802, the inner surface of the tube is wetted during the passage of the tool through the tube by at least one jet of lubricant ahead of the tool. The mandrel tool which is pulled through the tube to calibrate its inner surface is supplied with water soluble lubricating oil via a pipe (44c) (Fig. 16, not shown) and passages (85, 86) (Fig. 17, not shown) in the rod (51) on the end of which the tool is mounted. The tool (Fig. 19, not shown) is formed of heat treated steel or tungsten carbide and is provided with chamfers (91, 92) and an arcuate working surface (93) having a radius of 5-7 mm. or 10 mm. The die (55) for calibrating the outer surface of the tube is formed of heat treated steel, and is mounted in a pivotable die carrier (54). To ensure a uniform displacement of the tool through the tube or tube through the die, each of the two chambers of the jack (43) is provided with a valve (94) (Fig. 18, not shown) which allows unrestricted fluid flow into the respective chamber but limits the speed of discharge of fluid from the chamber.
