ABSTRACT:
An automatic insulation block milling machine is disclosed. The machine combines a series of operations into a single, automatic, production-line machine. Blocks of rigid insulation material, such as cellular glass blocks, are fed into the automated machine. The blocks are first placed on an automatic programmed moving conveyor belt and are first cut on a pre-determined angle developed from the horizontal and vertical centerline of the block. This cut is made by an angled, vertical band saw mounted with its blade in the center of the moving conveyor, thus producing one angled side on each of the two cut blocks. The remaining three primary sides of the cut blocks are machined to create curved sectional blocks that are used to cover the outer surface of large bore pipe systems or other cylindrical items such as tanks.
