  2. Custom Fixture Design and Build: Use the "Request Quote" button, and we’ll contact you directly. We’ll likely need prints and models of your parts at some point and will be happy to sign an NDA if needed.

  1. Standard Products: You’ll receive the quote within 1-2 business days.
  2. Custom Design and Build Workholding: These quotes can vary, depending upon design inputs and engineering requirements/workload. Our team will follow up and give you an estimate on how long your quote will take.

We can do both! More than 95% of tombstones are cast iron, but we do cast aluminum, epoxy mineral, and aluminum and steel weldment, depending on the application and its requirements.

  1. Tombstones: We keep stock of commonly ordered castings in specific sizes. We take these castings from stock and machine to your specification within 2-3 weeks. Our team generally does not stock finished tombstones.
  2. Design and Build Fixtures (manual, pneumatic or hydraulic): Projects for design and build can take 6-8 weeks or longer depending on the specification and the duration of the design and approval process.

Each tombstone and/or design and build fixture is inspected on our CMM’s to verify compliance to specification. Design and build fixtures have an additional approval and validation phase with the customer.

We use SOLIDWORKS 2018 for our designs, SOLIDWORKS CAM for cutting and programming, and Vericut for cutting path verification.

We can use a variety of brands depending on the specific application or customer preference. In addition to integrating our own products, our team utilizes fixturing options from our Build on the Rock (BOTR) partners: 5th Axis, Martin Trunnion, Mitee-Bite, Schunk, Triag, and Vektek.

Yes! We have developed many hydraulic and pneumatic fixtures.

There are many different variables that are considered when choosing a tombstone material. Review our whitepaper on Tombstone Testing for Dynamic Performance compiled by Tony Schmitz, PhD. to learn more about how to choose the best material for your application, including analysis on vibration, damping, and more.
