ToolBlox™ Caged Workholding Tombstones

Kurt® Workholding’s two-face add four face ToolBlox modular tombstones (or caged tombstones) provide a lighter weight building block to add high density and even greater versatility to horizontal CNC machining centers. Our caged tombstones are over 30% lighter than most comparably sized tombstones with aluminum sub-plates, and are uniquely designed to reduce setup time.
ToolBlox tombstones are a lower cost alternative to dedicated fixtures. The bolt holes and dowel pattern on each face enable the fast and easy installation/removal of sub-plates and other workholding components, such as manual or hydraulic vises and other part clamping devices.
Four ToolBlox caged tombstone models are available, all manufactured from Class 30 grey iron for durability, stability, and long working life. Two-face and four-face models are available with 400 mm or 500 mm bases. Standard and custom sub-plates are available for all models. (see below).
Solid workholding tombstones are also available. 

What is A Workholding Tombstone?

A workholding tombstone is a specialized fixture with two or more faces onto which parts, or other devices that are used to hold those parts, can be mounted for machining purposes. Modular tombstones are most frequently used in automated manufacturing systems, such as horizontal CNC machining centers, to improve productivity.
  1. Parts are mounted on the tombstone, with or without the use of additional workholding devices,
  2. Machining and/or other operations are performed on parts on one face,
  3. The tombstone is rotated so that operations can be performed on parts on an adjacent face,
  4. Steps 2 and 3 are repeated until parts on all faces are processed
Workholding tombstones are also known as tooling towers, tooling columns, pedestal fixtures, and fixture blocks.

ToolBlox Sub-Plates

Kurt Workholding offers a full line of standard sub-plates for ToolBlox modular tombstones to meet your CNC machining requirements. All sub-plates can be bolted or doweled directly to the tombstone to provide fast change-out for dedicated fixtures, with ±0.0002” repeatability. Kurt vises can be permanently mounted to sub-plates for quick and easy setup changes on CNC milling machines.
Specify 6061 T6 aluminum or A36 HRS. Optional hole patterns and/or keyways can be custom-specified to meet your requirements. Contact Kurt to order sub-plates for your ToolBlox modular tombstone.
