Document Type and Number:
Japanese Patent JP3037857
Kind Code:
B2
Abstract:
PURPOSE: To grind surface flaws smoothly by making pressing force by a contact roll variable depending on the directions, and concurrently alter a grinding mode at a flaw section from that at its vicinity.
CONSTITUTION: The horizontal movement of a contact roll 5 is controlled by an operation control means 17 via a position control means 19 based on the positional information of a moving position detecting sensor 16. The pressing force (going up and down) of the contact roll 5 is so designed as to be switched over to the two kinds of a finish grinding mode and a rough grinding mode. The switching condition is set up in advance in response to the outbreak condition of flaws, the aforesaid condition is controlled by a pressure control means 20 controlled by the operation control means 17, and a cylinder mechanism controlled by an electromagnetic valve 21 based on the horizontal moved quantity signal of the contact roll 5 by the moving position detecting sensor 16 and the vertical moved quantity signal of a ascent and descent position sensor 30.
