Reversible workbed support members for laser cutting machine

摘要

A workbed comprises a plurality of parallel support members with each support member having a first edge with a contact surface of a specific configuration. A second, opposed edge with a second contact surface on the support member is also provided with the same specific configuration. As a result, instead of replacing the support member each time the first edge's support surface is worn or degraded, it can be flipped, or reversed so that the second, edge's support surface of the support member is used to form the workbed.
