Why U need the U Series 5 Axis?
The new U Series 5 Axis Machining Center gives your workshop the versatility to machine smaller, less expensive components without the expense or large floor plans of a swivel head machine.
Perfect for Small Batch Production
​
If you need to machine less expensive components economically, the trunnion type 5-axis machine is the perfect choice as it delivers greater machining volume compared to more expensive swivel head machines.
Higher Cutting Speed, Longer Tool Life
​
With the 5-axis design, you use shorter tools that can be oriented toward the cutting surface. This means that you cause less stress to the cutting tools at high speeds and can prolong cutting tool life, saving your money.
Extended Undercut Capability
​
The U series machine delivers 120 trunnion swivels, which allows you to complete components in a single setup without the repositioning that could be required on other machines.
Greater Working Volume within a Smaller Space
​
As the movement is handled by the worktable rotation, there is no need for a large working area to accommodate a swivel head. You can save on space as well as costs with our 5-axis vertical machining center.
Unique I.D.D. Spindle
Design
​
Ceramic ball bearing in the spindle to carry out high dynamic accuracy, high rigidity, and also provides a longer service life. Direct-driven spindle motor ensures better torque transmission, decreased noise and backlash, and reduced vibration. An inline, direct-driven spindle that is coupled directly to the motor provides smooth operations for excellent surface finishes and is equipped with a spindle oil cooler, which reduces operating heat for greater thermal stability.
Complex Shape Machining: One Set Up
​
For prototyping, you can machine extremely complex shapes directly from a solid block, so you have no need to first go through a casting process and then machining. This drastically reduces your production time and saves you significant money on the casting part of the process.
