Cube Cnc Tombstones

Cube Tombstones are ideal when a larger workholding surface is required, enabling efficient four-sided machining operations. These tombstones maximize part capacity and accessibility, making them well-suited for complex, multi-face setups. If a smooth, unfeatured surface is not preferred, our cube tombstones can be equipped with various grid patterns, including the industry-standard 2″ grid, T-slots, or fully customized configurations.

Key Features

Grid hole patterns, precision bushings, and inserts are available for both 1/2″ and 5/8″ systems to suit a range of clamping needs
Hardened threaded inserts provide secure fixturing at every hole location and are designed for fast, simple replacement when worn
High-precision, heat-treated bushings are precisely positioned for reliable, repeatable part alignment and excellent resistance to wear
Replacement bushings, inserts, and extraction tools are available upon request to support long-term maintenance and usability
