Document Type and Number:
Japanese Patent JPH0460768
Kind Code:
B2
Abstract:
Hardmetal lamina (15) are cut, by a process known as electrical discharge machining, from a block of hardmetal (10) using a wire electrode (12). The laminae so formed may then be attached by adhesive or epoxy resin to a suitable base (16) in order to form a hard metal surfaced tool. Provision is made for preventing this hardmetal from shearing from its mounting, and also to remove any heat generated within the hardmetal. Reference is made especially to using the above construction for a 'slipper' within a tile producing machine. The word 'hardmetal' is used to denote powdered carbides of the transition metals, cemented into solid masses by a matrix of a metal of a lower melting point.
