Abstract:

Generally rough sphere-shaped work pieces made of fragile material are ground into more uniform spheres. The rough spheres are fed into a holding plate having a channel cut into the bottom side of the plate with a width slightly larger than the largest diameter of the rough spheres. A movable abrasive surface is positioned adjacent to the bottom side of the holding plate. As the rough spheres move through the holding plate which can be vibrated, they move in contact with each other and with the abrasive surface. The finally formed spheres leave the plate where they are collected. It is a further embodiment green spheres which are treated in a sintering process with hydrogen gas have tungsten oxide particles applied to the surface of the spheres prior to and during sintering so that the particles remain separated and apart.

Abstract:

Die assemblies for forming a firearm projectile and methods of utilizing the die assemblies are disclosed herein. The die assemblies include a forming die, a first punch, and a second punch. The forming die defines a first side, a second side that is opposed to the first side, and a die cavity that extends between the first side and the second side. The first punch is configured to seal against the forming die from the first side. The second punch is configured to be received within the die cavity from the second side. When the first punch seals against the forming die and the second punch is received within the die cavity, the first punch, the second punch, and the forming die collectively define a forming surface shaped to define an external contour of the firearm projectile.
