Dedicated milling fixtures
Op-10/op-20 fixtures with 3-2-1 location, positive part orientation and clamp access planned around the tool path.
CNC workholding fixtures
The part is only as accurate as the fixture holding it.
Dynamics Group designs and builds CNC workholding — dedicated fixtures, soft jaws, nests and multi-part pallets — with the datum logic, clamp access and repeatability the machining process actually needs.

Where we fit
Workholding designed by people who run the machines
A workholding fixture is judged at the spindle: does the part load one way, clamp without distortion, clear the tool path and repeat across the run? Dynamics Group builds fixtures for its own production floor and applies the same standard to yours.
Soft jaws and nests
Machined jaws and nests for castings, extrusions and irregular blanks that a standard vise cannot locate.
Multi-part and pallet fixtures
Higher-density setups that cut per-part load time on repeat work.
Distortion-aware clamping
Clamp placement and support chosen around thin walls and finish requirements, not just holding force.
Proof before promise
Capability behind the fixture
- Engineering
- Mechanical design, datum strategy and DFM review before steel is ordered
- Machining
- Six VMCs, a swivel-head 5-axis machining center and live-tooling turning for fixture details
- Proving
- Fixtures can be run off on in-house machines before delivery
- Verification
- Locator and net-pad positions checked on in-house CMM and probe metrology

Buyer questions
Straight answers before you send a print
Do you build fixtures for parts you don't machine?
Yes. Workholding design and build is offered as its own scope — send the part model, machine and process details, and the tooling concept can be developed for your equipment.
Can you design the fixture from just a part model?
Yes. The part model, target machine, operation sequence and datum scheme are enough to start; missing details are identified in the design review.
How is fixture accuracy verified?
Machined locator and net-pad positions are checked on in-house metrology against the fixture design before delivery.
Are weld fixtures the same thing?
No. Weld fixtures hold assemblies for joining and have their own page. This page covers workholding that locates and clamps parts for CNC machining.
Do you also design the clamping itself?
Yes. Quick-change clamping, powered clamping and distortion-aware clamp layouts for series production are covered on the CNC clamping devices page and are usually quoted alongside the fixture.
