Abstract
The present invention eases possible rubbing between an upper cutting edge and a work cutting surface of a work cutting apparatus during the elevation of the upper cutting edge to prevent the upper cutting edge from being worn in order to increase its lifetime. In a device for cutting a work by elevating and lowering a movable upper cutting edge 12 relative to a fixed lower cutting edge 13, an upper-cutting-edge, tight-contact avoidance device 10 is provided for widening the clearance between the upper cutting edge 12 and a work cutting surface. The device 10 is comprised of a clearance adjustment mechanism 22 for adjusting the clearance between the upper cutting edge 12 and the lower cutting edge 13, and control device 35 for regulating operation of the clearance adjustment mechanism 22.
