Precision Machining for One-of-a-Kind Parts, Urgent Repairs & Short Runs

Horizontal & Vertical Precision Milling

Our Grizzly G0827 combines horizontal and vertical spindles in one machine, letting us handle a wide range of operations without changing setups. With a 3-axis DRO and 0.0002" resolution, you get repeatability you can count on.

• Flat faces ("flats") on shafts — like the 107" Main Shaft that needs flat surfaces for set screws.
• Keyways and slots on shafts, pulleys and gears.
• Spur and helical gears (with horizontal head and proper tooling).
• T-slots and dovetails for machine tables and guides.
• Base plates and flanges with mounting holes and machined surfaces.
• Slotting and internal grooving with the vertical head.
• Pocketing and cavity milling in blocks and housings.
• Chamfering and beveling of edges for welding.
• Long material cutting with the horizontal spindle (up to 29" longitudinal travel).

Materials: Carbon steel (1045, 1144, 4140), stainless steel (304, 316), aluminum, bronze, brass, and cast iron.

Precision Turning & Shaft Machining

Our Grizzly G0509G 16" x 40" lathe is built for high-precision work. With a 2.0625" spindle bore we can handle long shafts without vibration, and its "spider mount" system stabilizes long parts for critical operations.

• Drive shafts and rudder stocks — turning, facing and diameter fitting.
• Bushings and sleeves — made from scratch or reconditioned.
• Cylinder liners — ID grinding and fitting.
• Precision threading — metric, Whitworth, UNF, NPT and special threads.
• Bearing and seal housing boring.
• Flange and faceplate facing — flat surfaces perpendicular to the axis.
• Drilling and reaming on the lathe with proper tool holders.
• Internal and external grooving for retaining rings and seals.
• Tapers and chamfers with the compound rest.
• Polishing and surface finishing for fine tolerances and sealing.

Lathe capacity: 16" swing over bed · 10" swing over carriage · 40" between centers · 2.0625" spindle bore.

Custom Part Manufacturing (One-Off)

Need a part that is no longer made? Have a damaged sample but no drawing? We work with reverse engineering: we measure the original part, interpret its specs, and machine it again with the same — or better — dimensions.

• Bolts, studs and special screws.
• Pins, keys and wedges.
• Stepped shafts and drive shafts.
• Pulleys, gears and pinions.
• Flanges, plates and brackets.
• Special tools and tool holders.
• Naval and industrial machinery components.
• Obsolete or discontinued spare parts.

Key advantage: No minimum quantity. We machine from 1 piece up to short runs of 10 to 50 units.

Repair & Reconstruction of Components

Many times you don't need to replace a costly part. We can repair, rebuild, or recondition it to extend its service life — at a fraction of the cost of new.

• Worn shafts — grinding and fitting to original or oversize dimensions.
• Bearing housings — boring and fitting.
• Damaged threads — repair or re-threading.
• Sealing surfaces — facing and polishing.
• Deformed keyways — milling and fitting.
• Bushings and sleeves — rebuilding or replacement manufacturing.
• Gears with damaged teeth — replacement or repair.
• Cracked or fractured parts — evaluation and possible reconstruction.

Signature service: "You bring the part, we machine it." Bring us the damaged component or raw material, and we return it ready to install.

Special Tools & Fixtures

We manufacture cutting tools, work-holding fixtures, and special accessories for shops, production lines, and industrial maintenance teams.

• Cutting tools and lathe/mill bits.
• Punches and simple dies for cutting and bending.
• Custom supports and fixtures.
• Special wrenches and tools for machinery.
• Guides and stops for production.
• Tool holders adapted to specific machines.

Flat Surface Milling on Large Parts

Thanks to our horizontal head and 29" longitudinal travel, we can mill flat faces on long shafts and parts that don't fit — or aren't cost-effective — in other shops.

• Flat face milling on drive shafts (like the Main Shaft case).
• Flattening of base plates and tables.
• Milling of key seats on long shafts.
• Surface preparation for component assembly.

Short-Run Production (5–50 Pieces)

We're not a mass-production shop — and that's a good thing for you. We handle short runs of 5 to 50 pieces with consistent quality, thanks to our DRO and machine repeatability.

• Functional prototypes.
• Small batches of spare parts.
• Limited production of components.
• Replacement parts for obsolete machinery.

Note: For larger productions, we evaluate each case and can recommend alternatives or subcontract specific processes.
