Trunnion System and Rotary Indexer shown in VMC

ONLY ONE 4th Axis is required to get the benefits of a Horizontal Machining Center on your VMC equipped with an Automatic Pallet Changer. Increase 4th Axis productivity by adding our MIDACO TRUNNION SYSTEM and Vertical Rotary Faceplate to a New Automatic Pallet Changer. Turn your Vertical into a Horizontal with NO cable management needed!



Yrunnion System shown with 2 trunnons and rotary indexer

The MIDACO TRUNNION SYSTEM includes one 4th Axis actuator assembly and two trunnions (individual trunnion is also available separately), and works with any 4th axis rotary-indexer (not included). A trunnion is mounted on each pallet of the Pallet Changer outside the VMC. Once transferred into the machining area, the trunnion clamps onto the MIDACO receiver and automatically engages with the 4th Axis. The Trunnion System is a cost effective solution to increase your Vertical’s capability by machining 360 degrees without the need for cable management. 

2 Vertical Rotary faceplates shown tslot and spindle holes


Increase your machining versatility by adding a Vertical Rotary Faceplate, available with t-slots or spindle holes, for multiple workholding options.
