What Are 5th Axis Tombstones?

What Are 5th Axis Tombstones?

Tombstones are precision-machined structures that allow multiple parts or vises to be mounted vertically, increasing machine spindle access and maximizing part density. Designed for horizontal and vertical machining centers, they are a core part of high-volume and high-precision production setups.

Features

• Optimized for 5-Axis Access: Designed to reduce setup changes by enabling multiple workpiece orientations in one cycle.
• Multiple Mounting Surfaces: Typically, 2, 4, or 6 sides depending on the tombstone design.
• Rock-Solid Construction: Aluminum or steel bases with hardened steel locating features for repeatability.
• Modular Compatibility: Compatible with 5th Axis dovetail fixtures, vises, and RockLock quick-change systems.
• Custom Heights & Sizes: Available in a variety of configurations to suit machine envelope and part size.

Benefits in Production

• Reduce Downtime: Load/unload outside the machine with quick-change capability.
• Increase Throughput: Machine more parts per cycle, less manual intervention.
• Improve Accuracy: Single setup for multi-face machining reduces cumulative error.
• Scalable: Stackable or swappable fixtures for job flexibility.
