CNC OD/ID Grinding Machinist

\n

Grinding is different.

\n

Anyone can load parts into a machine. Great grinding machinists understand how to read the part, control the process, and consistently produce tight-tolerance components that customers depend on.

\n

That's what we're looking for at KMM Group.

\n

Our team manufactures precision components used in medical devices, aerospace, defense, and space exploration. The work is challenging, the tolerances are tight, and quality matters on every part.

\n

If you enjoy precision work and want to continue developing your grinding skills on modern equipment alongside experienced craftspeople, we'd like to talk with you.
