Universal milling slotting boring tooling comprises radially tooled toolholder front powered via gearing and pulley or variably tooled for fullface boring with spoil removal without degradation.

摘要

A tooholder (2) mounted on an inner or outer ring (3) in the housing (5) is radially tooled (1) on its front face. The rear face of the toolholder (2) carries a large toothed ring, sprocket, belt pulley etc rotated by motor (8) with smaller gear or pulley at slower speed to load freed material or spoil out to the rear, possibly via container. A line of splitting or cleaving tools used includes doubly-roofed conical slotting tools. A fullface boring tool is ringed by a cone of tools, the fullface boring tool replacing the radially arranged slotting tools and fixed by an adapter. Operational uses include tree stump removal and underground containing machines as well as excavator plant.
