Buell Precision Machining Capabilities
At Buell Automatics, we don’t just make parts, we craft solutions. With decades of experience under our belts, we’ve honed our skills to deliver machining services that meet the toughest demands. From high-volume production runs to intricate, tight-tolerance components, we’ve got the tools, expertise, and dedication to get the job done right.
Here’s a closer look at what we do best.
Multi-Spindle Precision Machining
When speed, consistency, and precision matter, multi-spindle machining is the way to go. Our machines perform multiple operations simultaneously, slashing production time while maintaining exacting standards.
What We Offer:
- High-Volume Production: Capable of producing thousands of parts per day with minimal variation.
- Complex Geometries: Handling intricate designs that would slow down single-spindle setups.
- Wide Material Range: From aluminum and brass to stainless steel and specialty alloys.
Our multi-spindle setups excel at making parts like bushings, fittings, fasteners, and connectors (components where precision can’t be compromised).
Davenport Screw Machine Services
Since 1966, we’ve been running Davenport screw machines like nobody else. These aren’t just old machines, they’re legends that are meticulously maintained and upgraded to perform like new.
Why Davenport?
- Built for Speed: Capable of producing up to 30,000 parts per day with tight tolerances (±0.0005″).
- Versatile Attachments: Threading, knurling, cross-drilling, flat generating—you name it, we do it.
- Proprietary Monitoring: We’ve added modern sensors to track performance, ensuring every part meets spec.
Whether it’s hydraulic fittings, electrical connectors, or custom prototypes, our Davenport machines deliver.
Precision Turning and CNC/Swiss Machining
Since 2010, we’ve been pushing the limits of what Swiss turning can do. If you need small, complex parts with tight tolerances and smooth finishes, this is where we shine.
Swiss Turning Advantages:
- Unattended Operation: Machines run for hours without intervention, cutting labor costs.
- Oil-Based Coolant: Smoother finishes and better chip control than water-based systems.
- Sliding Headstock & Guide Bushing: Perfect for long, slender parts that need stability.
From medical components to aerospace fittings, Swiss turning lets us tackle jobs that conventional lathes can’t.
CNC Milling and Turning
While we don’t mill in-house, we’ve built strong partnerships with trusted specialists who do. When you need milling (whether it’s 3-axis, 4-axis, or complex contouring), we make sure it’s done right.
Turning, however, is all ours.
- CNC Lathes: Handle diameters up to 2″ with precision.
- Multi-Tasking Machines: Combine turning, drilling, and threading in one setup.
- Material Flexibility: Steel, stainless, brass, titanium. We work with it all.
Need a turned part with milled features? We’ll coordinate the entire process.
Knurling
We provide precision knurling services to create functional grip patterns or decorative finishes on machined components. Our capabilities include:
- Diamond, Straight & Diagonal Patterns: For improved grip or visual appeal
- Multiple Techniques: Scissor, bump and end-roll knurling methods
- Internal & External Applications: Textured surfaces on both OD and ID
- Material Versatility: Works with brass, aluminum, steel and stainless
Common knurled parts we produce include knobs, handles, fittings and adjustment collars where secure gripping surfaces are needed. Our processes maintain tight tolerances while achieving consistent pattern quality.
Threading
Threads might seem simple, but getting them right is an art.
We specialize in:
- Internal Threading (cut tapping for clean threads, form tapping for strength).
- External Threading (cut for appearance, rolled for durability).
- Thread Milling (ideal for large or hard-to-machine materials).
Whether it’s a fine-pitch medical screw or a heavy-duty hydraulic fitting, our threads hold up under pressure.
Coolant-Through Deep Hole Drilling
Drilling deep, straight holes isn’t easy, unless you’ve got the right setup. Our coolant-through (CT) drilling pushes high-pressure coolant directly to the cutting edge, keeping things cool and clearing chips efficiently.
Why CT Drilling?
- Single-Pass Operation: No need for multiple drills or reaming.
- Precision & Straightness: Achieves depth-to-diameter ratios of 6:1 or greater.
- Works in Tough Materials: Steel, stainless, brass, no problem.
Common applications include fuel injectors, hydraulic fittings, and compression limiters.
Secondary Services
Machining is just the beginning.
We also arrange:
- Heat Treating (for stronger, more durable parts).
- Plating (barrel plating for small parts, rack plating for delicate ones).
- Grinding & De-Burring (smoothing edges for a flawless finish).
- Passivation (boosting corrosion resistance in stainless steel).
By handling these through trusted partners, we save you the hassle of juggling multiple vendors.
Why Buell Automatics?
- 50+ Years in the Game: We’ve seen it all and know how to adapt.
- No-Nonsense Quality: ISO 9001:2015 certified, IATF 16949, and ITAR compliant.
- End-to-End Solutions: From prototype to full production, we’ve got you covered.
Whether you need 10 parts or 10,000, we’re here to make them right.
