When you’re looking to do production work, or just looking to machine multiple parts at the same time, a CNC tombstone provides a way to fit several parts for many different operations into the same setup. When combined with an automatic tool changer (ATC), a tombstone can provide an easy solution to milling multiple parts that you can set and forget while your parts are machined. Tombstones, also sometimes known as pedestal fixturing, tooling tower, or fixture block, have two or more sides, typically four, that you can affix parts directly or attach various fixture plates.
The Tormach Tombstone is designed to fit on our 6” or 8” rotary tables and the fixture surfaces are left as-cast, allowing users to fully customize their workholding by machining the tombstone to fit specific applications. There are two ways to really utilize tombstone manufacturing.
Number two is the method we used to create whistles for last year’s Tormach Open House. Handing out aluminum whistles was a great idea, but machining one at a time would have taken ages. So, we designed some fixturing and attached it to a tombstone.
