Claims

[Scope of utility model registration request]

A horizontal vise that presses a plurality of rod-shaped materials that are arranged close to each other parallel to each other on a cutting table from both sides as they approach the intended cutting position, an elevating clamp that presses these materials from above, and an elevating clamp that presses the materials from above. a device for detecting the amount of descent from a raised position to a lowered position where it contacts the material; a movable table supported on a base supporting the cutting table so as to be able to move forward and backward in a direction perpendicular to the material; A drive device that moves the table, a swinging arm that is pivoted on the moving table so that it can swing in a vertical plane, and a horizontal rotating shaft provided at the tip of this swinging arm that is sandwiched between mounting flanges. an attached rotating grindstone, a drive device for swinging the swinging arm so that the rotating grindstone cuts the material at the scheduled cutting position, and a device for detecting the amount of descent of the rotating grindstone from the raised position; The lower position of the mounting flange detected by the descending amount detection device approaches the height of the material detected by the lifting clamp descending amount detection device or the known height of the horizontal vise. A rotary grindstone-type cutting device comprising a control device that controls a drive device for the swing arm to stop the movement when the movable table is moved, and then starts the operation of the drive device for the movable table.
