At Jerpbak-Bayless Company, precision is more than a standard — it’s how we’ve operated since 1945. For decades, we have supported industries that demand accuracy, reliability, and efficiency in every part they use. With a large facility and a dedicated team of machinists, engineers, and support staff, we have built a reputation as a trusted partner for custom part manufacturing.
Our services focus on precision machining, and over the years, we’ve expanded into advanced processes that help our customers solve difficult production challenges. From specialty machining and grinding to advanced CNC milling and threading, every project is approached with the same commitment to precision and reliability. Whether you need prototypes or high-volume runs, Jerpbak-Bayless has the people, equipment, and knowledge to make it happen.
CNC Turning
CNC turning is one of our core strengths. With 2- to 5-axis turning centers, we handle a wide range of projects, from small precision components to large-scale shafts with center distances up to 200 inches. The flexibility of our machines allows us to support both short runs and long production cycles without compromising on quality.
Many industries depend on our turning capabilities to produce parts that meet strict dimensional and performance requirements. Shafts, sleeves, bushings, and pump components are just a few examples. The accuracy achieved through our CNC turning equipment provides the foundation for more advanced machining processes such as grinding or spline cutting.
If your application calls for high precision, smooth finishes, and repeatable results, our CNC turning department is equipped to deliver. With large work envelopes and experienced operators, we can handle challenging jobs that other shops may struggle to complete.
CNC Milling
Our CNC milling capabilities allow us to tackle complex geometries with accuracy and efficiency. We operate both vertical and horizontal machining centers, many with 4- and 5-axis functionality, and with travel spans reaching up to 200 inches. This combination gives us the ability to produce intricate parts while reducing setup time and improving accuracy across all features.
A key part of our milling expertise is helical milling, which allows us to produce spiral grooves, channels, and other demanding features that are critical to fluid dynamics, aerospace components, and specialized equipment. By using multi-axis milling, we reduce the need for multiple operations, which translates to faster turnaround and consistent results for our customers.
From one-off prototypes to full production, our CNC milling department supports industries that need precision without delays. Whether you require complex housings, pump bodies, or detailed OEM parts, our team has the capability to machine them with confidence.
Custom Threading
Threading is another capability that sets Jerpbak-Bayless apart. We offer a full range of threading services, including thread grinding, thread milling, and honing. This allows us to create custom threads that meet specific pitch, depth, and tolerance requirements.
For power transmission and rotating equipment, we often combine threading with spline cutting to produce shafts that are both durable and precise. These components are used in industries such as energy, oil and gas, and heavy equipment, where failure is not an option.
We also specialize in machining twin pump screws, which are vital to many pumping systems. Accuracy in these parts is critical, as even the smallest deviation can affect efficiency and performance. Our machining processes deliver the consistency needed for these demanding components.
No matter the application, if your project requires threads that are exact and reliable, Jerpbak-Bayless has the equipment and experience to produce them.
Specialty Machining
At the core of our capabilities is specialty machining. This is where we handle the parts and processes that go beyond standard machining. Our specialty work includes spline milling, gun drilling, honing, and large-capacity OD grinding, with center distances up to 233 inches. We also operate a 150-ton shaft straightening press for projects that require additional forming and correction.
Specialty machining allows us to serve customers with unique part designs, challenging material requirements, or oversized workpieces. From heavy shafts to precision splines, our combination of equipment and technical knowledge allows us to support projects that demand an experienced partner.
We don’t just provide machining — we provide solutions that keep your operations running smoothly. Whether you need precision splines, deep-hole drilling, or large-diameter grinding, Jerpbak-Bayless has the capability to deliver.
Materials Expertise
The choice of material often determines how a part performs under stress, temperature, or environmental conditions. At Jerpbak-Bayless, we have extensive experience working with a wide range of materials, including:
- Stainless steels
- Nickel-based alloys
- Aluminum
- Bronze
- Cast iron
Each material comes with its own challenges, but our machinists know how to handle them efficiently while maintaining tolerances and surface finishes. Whether it’s the toughness of nickel alloys, the workability of aluminum, or the strength of stainless steel, we have the expertise to get it right.
This knowledge allows us to support demanding industries where materials must meet specific standards for strength, corrosion resistance, and reliability.
Large-scale and Specialty Equipment
Our facility is built to handle projects of varying sizes and requirements. With 42,000 square feet of space and a 5-ton crane capacity, we can accommodate oversized workpieces that many other shops cannot.
Some of our specialty equipment includes:
- Vertical machining centers with long travel spans
- Horizontal machining centers for efficient production
- OD grinders with up to 233-inch center distance
- Spline milling and hobbing machines
- A 150-ton shaft straightening press
This range of equipment gives us the flexibility to meet customer needs across different industries and applications, while keeping work in-house to maintain quality control.
Quality and Compliance Standards
Quality is part of everything we do. Jerpbak-Bayless is certified to ISO-9002 and MIL-I-45208, which means our processes are structured to meet strict requirements. We apply quality checks at every stage of production, including in-process inspections and final verification, to confirm that each part meets exact specifications.
By combining skilled machinists with rigorous inspection procedures, we provide the consistency and reliability our customers count on. Whether the order is for a single prototype or a long production run, our approach to quality never changes.
Industries Served
The range of industries we serve reflects the flexibility of our machining capabilities. Some of the sectors we work with include:
- Aerospace: Precision components for turbine systems, shafts, and threaded parts that must withstand extreme stress and temperature conditions. Our expertise in helical milling and spline cutting is especially valuable for aerospace drive and power systems.
- Oil and Gas: Critical pump and drilling components, including twin pump screws, housings, and custom threaded parts.
- Automotive: Shafts, splines, and precision machined parts for drivetrains and engine assemblies.
- Energy: Components for turbines, compressors, and power generation systems. Our ability to machine stainless steels and nickel-based alloys helps us deliver parts that can withstand high heat and stress in energy production environments.
- Heavy Equipment: Large shafts, bushings, and machined parts for construction, mining, and industrial machinery.
Each industry has its own requirements, and our ability to deliver specialty machining, helical milling, spline cutting, and twin pump screws means we can support projects where precision and durability are critical. From turbine components in aerospace to pump parts in oil and gas, Jerpbak-Bayless plays a role in keeping industries moving.
