Hot Mill Rotary Piercer Roll Shaft. CNC Lathe Machining.

Seamless pipes are manufactured by a number of cold as well as hot rolling processes. The hot rolling process used to manufacture pipes at about 1250-1300 deg. Celsius is known as Hot Piercing process. The piercing is carried in a plant known as the piercing mill, which consists of a number of dies, of which, two primary contoured work rolls rotate in the same direction with their axes at 3 to 6 degree with respect to the horizontal stock plane. The process is also known as rotary piercing or seamless tubing.
