Abstract

A slicing apparatus includes: an annular plate-like rotary blade adapted to be rotated about an axle thereof and having an inner peripheral cutting edge; a table for carrying a work; a first work-feeding mechanism for moving the work on the table in a direction parallel to the axis of the rotary blade; and a second work-feeding mechanism for moving the table in a direction parallel to the opposite side of the blade so as to cause the work on the table to be sliced by the blade. The second work feeding mechanism includes: a hydraulic cylinder operatively connected to the table; a pressure oil-supplying mechanism for supplying the hydraulic cylinder with a pressure oil; a rotary valve for controlling the flow rate of the pressure oil to be supplied to the hydraulic cylinder, the rotary valve having a rotary input shaft of which rotational position determines the flow rate of the pressure oil passing through the rotary valve; a drive mechanism for rotating the input shaft of the rotary valve; a cutting speed sensor for substantially detecting the travel speed of the table which is moved by the hydraulic cylinder and for outputting a feedback signal; and a control unit for controlling the drive mechanism according to the feedback signal outputted by the speed sensor so that the actual travel speed of the table is equal to a predetermined travel speed for the table.
