Your Hays-Area Machining Service
Along with our testing services, Trilobite operates a full-service machine shop at our Hays, KS, location. We can design, produce, modify, and repair metal parts and assemblies for oil field applications, agricultural operations and work in many other industry sectors.
Whether you need a quick shaft repair or a batch of parts fabricated from raw stock, we’ll be happy to discuss your project. We provide machining services to customers throughout Ellis County and beyond.

About Our Machining Capabilities
The Trilobite machine shop was created to handle specialty projects rather than large-scale production work. Because we specialize in manual machining, bringing your job to us means you won’t have to offset programmer costs or help subsidize a multimillion dollar machine investment.
Our Hays machine shop features two lathes, both capable of cutting standard, tapered, and metric threading:
Lehigh MB-33160 Oil Country Lathe
-
9" Spindle Bore
-
Swings of 33" over bed, 23" over cross slide, 40" in gap
Grizzly 20"x60" Big Bore
-
3.15" Spindle Bore
-
Swings of 20" over bed, 12" over cross slide, 29" in gap
We also have a Bridgeport 9"x42" J head mill with CNC capability for CNC profiling and thread milling and a Harig 6"x12" surface grinder for achieving precise dimensions.
Welding, Fabrication, and Specialty Services
We can perform metal spray shaft repair to return a workpiece to its original dimensions. This process delivers a consistent coating of metal to build a surface back up for precision machine work. For longer parts that need precise through-holes, we can perform gun drilling.
Our Hays location offers welding services as well, including:
-
SMAW
-
GMAW
-
FCAW
-
GTAW
Call us for fabrication and repair on:
-
Changeover and rotary saver subs

Any type of SWD pump, including hydro-cell
Whether you need us to weld together a broken part, restore a worn component, or fabricate something new, we’re ready to help.
