Ordering Guide

Please specify these 5 items when ordering:

1. Part Number (unless you need a special configuration)

2. After each part number specify

  • "C" (casting only)
  • "BO" (base machined only with mounting holes and locating description and overall height finish with lift holes)
  • "BS" (plain machining complete)
  • "D" (dedicated machining)

3. Material: Cast Iron, Aluminum, or Steel

4. Quality: Standard or Precision

5. Machining Specification

All tombstones are made to fit your machining center either by edge locating or with hardened and ground wear pads, center locating, or just plain mounting holes to your specifications.

We can provide plain faces, hole grid patterns with precision bushings and threaded inserts, precision T-slots, or any machining to your specifications. All configurations are available in standard or precision. All tombstones and plates are stress relieved. We also specialize in hydraulic/pneumatic or manual dedicated fixturing. We at Advanced Machine & Engineering have a complete team of engineers to design and build whatever type of fixture you might need.

Approval drawings are provided before manufacturing. CMM report is available upon request.
