Description

PLANO MILLER}

The present invention relates to a plenum mirror, and more particularly, to a plenum mirror capable of working in a narrow space.

In general, rolling mills in the steel industry conduct thickness control through AGC (Automatic Gauge Control).

At this time, the AGC operates by the hydraulic pressure and the pressure is high, so that there is a problem of crack when the mounting surface of the AGC cylinder supporting it is uneven.

In order to prevent this, the seating surface of the AGC cylinder is uniformly machined. This is located inside the housing of the rolling mill. Due to the interference with many structures and the narrow space inside, To process the seating surface of the AGC cylinder.

On the other hand, the plano miller is a machine that combines a planer and a milling machine with a rotary milling cutter instead of the bite of the planer.

These plenomillers are suitable for cutting large structures or heavy objects and are not used as field machines.
