In some cases, you’ll need to hold down a 3-D surface that doesn’t lend itself to flat vacuum or rollers. Thankfully Accu-Router has the experience and partnerships for almost any requirement.
Custom workholding fixtures are most common in aerospace, automotive, reinforced plastics, and some 3D wooden parts. Custom fixtures are commonly machined from aluminum and made to conform to the bottom side contour of the part including any desired locating points involved. Vacuum, mechanical clamps and other methods are specified for minimal setup to hold the part securely during machining. Some customers automate the load/unload of such CNC’s with robotic arms and custom end effectors.
