Abstract: A technical modification was performed by the Changzhou Baosteel Steel Tube Co., Ltd. to the pointing machine of its Φ102 mm CPE mill, and all the pre-set technological norms had been met during the start-up. However some units of the said pointing machine like the positioning damper were not designed so properly, causing some troubles. After the modification of the said damper focusing on enhancement of rigidity and simplification of structure thereof, the availability of the machine is increased and maintenance cost reduced.
