When automatic tool change is justified, you’ll find all Accu-Router designs incorporate key principles to stand up to long-term, reliable production.
Important — we consider a side-mounted tool rack/carousel design superior for a number of reasons versus a bridge-mounted carousel (designed to save $$$):
- Fixed position & rigid – highly repeatable
- Does not add extra weight to bridge – load can compromise tolerance over time
- Does not compromise dust control – spindle picks up tool vertically
- With high rapid rates, cycle time is not adversely affected
The tool change mechanism largely depends on the host Accu-Router’s holddown technology. When vacuum only is used, he most economical solution is a fixed position linear rack, mounted along either long edge of the machine table. Examples of single ply “vacuum only” applications include aerospace composites, plastics and aluminum.
Such designs commonly have 10-12 tools onboard with a rotary-actuated chip cover to keep out debris.
When Roller Assist holddown is used, both long table edges regularly pass underneath the rollers, so a column-mounted carousel (or rack to serve two spindles) is utilized beyond the roller envelope.
