Benefits of Trunnion 5-Axis Mill
Easy transition from 3-axis machining. The 5-axis trunnion style machining centers are an ideal configuration for 5-sided machining, especially if you've always worked on a 3-axis machine because the trunnion style design uses the same principles as 3-axis (i.e., you still machine in a linear fashion, but you just machine more sides). This means less training, less setup time, and more flexibility.
More clearance in Z-axis. The integrated design of the trunnion table 5-axis milling machine gives you more clearance in Z, especially compared to 3-axis VMCs with a trunnion table added to simulate a 5-axis machining center.
Seamless integration. Seamless integration of pneumatic and/or hydraulic fixtures is another benefit. We purposely designed the U-Series 5-axis CNC mills so you can easily feed the cables for these types of fixtures through the casting.
Better undercut + larger work volume + more torque. Other reasons to choose the trunnion style configuration include better undercut capability because the trunnion rotates 110 degrees, it allows you to reach more complex geometry on the part, compared to machines that only tilt 90 degrees. Compared to a swivel head design, the trunnion style gives you a larger work volume because you don’t have to compensate for the space used by the swivel head with the tool attached.
