Claims

[Scope of Claim for Utility Model Registration] 1. A grinding device for deflector rolls installed at the entrance and exit sides of a rolling mill, which comprises a motor-driven movable base that moves in the lengthwise direction of the roll to be ground; A roll comprising: a motor-driven elevating table; a motor-driven rotary grindstone installed on the elevating table at an angle with respect to the roll axis; and a mechanism for grinding the roll to be ground with the rotary grindstone. Grinding equipment. 2 The rotation ratio of the rotating grindstone and deflector roll is 2
The roll grinding device according to claim 1, characterized in that the rotary grindstone is driven so as to achieve the above.
