Workholding Repair & Sales

Get a grip on your manufacturing process again

Air leaks & loss of clamping force? Loss of concentricity? Broken Elements?


With over 45-years of workholding experience, NNG is a premier supplier & rebuilder of rotating hydraulic and pneumatic chucks, expanding mandrels, collet chucks, hydraulic self-centering steady rests, hydraulic cylinders, pneumatic cylinders, and a full line of driven tooling.

We resolve these issues by replacing them with our stock inventory as well as hard chroming and regrinding all surfaces.

Applying chrome assists in anti-corrosion/anti-pitting and prevents residual build-up, thus increasing the lifespan of the assembly.


Chuck Repair.

Additionally, the master jaws and wedge are repaired or replaced to resolve any backlash causing weak clamping force.

The repair process is effective on all types of workholding devices including chucks (power, manual, indexing, compensating, and self-contained), steady rests (hydraulic and pneumatic), as well as hydraulic actuating cylinders, hydraulic clamping, etc.

Our workholding facility offers sales, repairs, and exchange core programs for standard, special, and custom work-holding devices, precision sliding jaw power chucks, and collet chucks used in high volume, precision parts production.
