We’re wrapping up a full turnkey machining solution for one of our Midwest customers—and this project goes far beyond a standard trunnion setup.
What started as a conversation about “adding a 4th axis” quickly turned into a complete process redesign: custom workholding, CAM programming for a complex casting, and on-machine installation and prove-out on a brand-new Mazak machining center.
This is exactly the kind of project our team loves—because it pulls together every part of what we do best.
The Challenge: A Complex Casting on a New Machine
Our customer had just invested in a new Mazak vertical machining center. Their goal was clear:
Move a complex casting into production quickly
Reduce the number of setups and manual handling
Improve consistency and part quality
Free up internal resources by outsourcing the engineering and implementation work
Like many shops, they didn’t just need a rotary table and a trunnion. They needed a complete, reliable process that would be ready to run on day one.
That’s where our turnkey approach came in.
Engineering a Complete Workholding System
The first step was to design the right foundation for 4th-axis production.
Our engineering team started with the part and the machine model, then built a workholding solution from the ground up:
Custom trunnion/workholding layout tailored to the casting’s geometry and datum structure
Fixture design focused on rigidity, repeatability, and clear tool access
Vektek hydraulic workholding integrated to provide fast, consistent clamping and unclamping
Rotary integration with a Koma Precision 4th-axis solution, matched to the Mazak and the customer’s torque and accuracy requirements
Everything was modeled in 3D so the customer could see exactly how the part would clamp, how tools would approach, and how the casting would be oriented for each operation. This eliminated guesswork and reduced the risk of surprises once we were on the floor.
CAM Programming for a Complex Part
With the workholding concept locked in, we moved into CAM.
The casting geometry demanded thoughtful toolpath strategies to balance cycle time, surface finish, and tool life. Our programmers:
Built complete 4th-axis programs for all operations on the Mazak VMC
Used dynamic/tool-engagement strategies where appropriate to keep the spindle cutting efficiently
Sequenced operations to minimize repositioning, air cutting, and unnecessary tool changes
Simulated toolpaths against the actual fixture and machine envelope to avoid collisions and clearance issues
By tying together CAM programming with the workholding design, we ensured that the process was realistic, repeatable, and ready for production—not just theoretical.
On-Machine Installation, Setup, and Prove-Out
This week, our team is installing the system and proving it out on the customer’s Mazak.
That on-site phase includes:
Rotary and trunnion installation on the VMC table
Indicating, leveling, and dialing in center height so the rotary and workholding system are properly aligned
Setting up the fixtures and hydraulic workholding from Vektek, including hose routing and connections
Loading and validating CAM programs at the control
Running first-article parts and making any fine adjustments needed for optimal cycle time and finish
Documenting setup procedures so the customer’s operators can reproduce the setup confidently
The hand-off doesn’t happen until parts are coming off the machine to print and the process is stable.
Why Turnkey 4th-Axis Solutions Matter
For many shops, adding a 4th axis is no longer just about buying hardware—it’s about buying capability.
A true turnkey solution like this delivers:
Faster time to production – You’re not piecing together fixtures, programs, and tooling over months. The process arrives ready to run.
Less burden on internal engineering – Your team can stay focused on other priorities while we handle the heavy lifting.
Reduced risk and guesswork – Workholding, programming, and machine integration are all designed together by one team.
Repeatable results – Documented setups, proven programs, and robust fixtures make it easier to scale and train new operators.
Instead of treating the rotary, trunnion, and fixtures as separate purchases, we treat them as one integrated system built around your parts and your machine.
Partners in Precision
Successful turnkey projects depend on strong partnerships. On this build, we’ve been proud to work with:
Vektek, LLC – Providing the hydraulic workholding components that keep parts clamped securely and consistently
Koma Precision Inc – Supplying the rotary solution that makes 4th-axis capability possible on the Mazak
Bringing the right partners together allows us to deliver a system that is not only accurate and robust, but also practical for day-to-day production.
