Since 1969, Kernell’s Automatic Machining has delivered high-quality screw machining and CNC Swiss machining services. Screw machining relies on a rotating spindle to machine away material from a base stock. In this subtractive manufacturing process, the machine rotates the workpiece while the cutting tool removes excess material to achieve the intended dimensions in turned components. 

Kernell’s Davenport and Acme screw machines are used for making small- to medium-sized parts for a wide variety of markets, including: 

  • Aerospace
  • Agriculture
  • Automotive
  • Consumer
  • Entertainment
  • Fan Shaft Hubs
  • Food and Beverage
  • Hobby
  • Industrial
  • Lawn and Garden
  • Locks
  • Medical
  • Military
  • Wire Rope Fittings

Our Screw Machining Capabilities

At Kernell’s Automatic Machining, our production team designs and machines fixtures to decrease the total number of operations, speed up production cycles, and enhance accuracy. Our team adheres to our customers’ tightest tolerances and most complex geometry requirements.

Our screw machining capabilities allow us to deliver tolerances of ± 0.0005 inches for part diameters of 0.096 to 1.062 inches and lengths of up to 10 inches. Screw machines make fasteners, screws, and various threaded parts for medical and dental instruments, heavy machinery, electronics, appliances, and automobile assemblies. 

Screw Machining Materials

Screw machining is suitable for various plastic and metal materials. We work with the following material options:

  • Copper
  • Aluminum
  • Brass
  • Stainless Steel
  • Carbon Steel
  • Alloy Steel
  • Rigid Polymers
  • PEEK
  • Nylon

Compliance & Quality Standards

Kernell’s Automatic Machining relies on a quality management system certified by ISO 9001:2015. We offer a range of quality inspection services, including Failure Modes and Effects Analysis (FMEA) engineering to ensure your products meet our high standards.

Custom Add-Ons & Secondary Services

At Kernell’s Automatic Machining, we offer optional secondary and add-on services when clients order a primary machining service from our facility. Our secondary services include in-house assembly, and outsourced heat treatment, grinding, and plating. These services can improve the durability, appearance, and performance of machined components.

How We Manufacture Custom Components With Screw Machining

Kernell’s Automatic Machining builds our own tooling and specialty inspection devices in-house, which enables us to offer consistently high quality and competitive prices. Our vast collection of multi-spindle screw machines and Swiss CNC turning centers have specialized features and various work envelopes to accommodate workpieces of different sizes. They can produce small- to medium-sized high-quality components. 

Our array of machining technologies means we have a machine for nearly any project. Our multi-spindle screw machines are high-efficiency and can perform multiple operations simultaneously, and many of our machines are equipped with both milling and turning tool sets. 

Why Kernell’s Automatic Machining for Screw Machined Parts?

With over five decades of industry experience, Kernell’s Automatic Machining specializes in machining parts using Swiss CNC machines and screw machines. Unlike other similar manufacturers, we have much better reaction times to sudden problems. We pride ourselves on our problem-solving abilities, fair prices, and consistent high quality.

We can process order quantities of as few as 2,500 parts to mass-production orders. This is possible because we automate bar feeding and part handling to run our machines continuously, resulting in high-velocity output. Thus, screw machining is a cost-effective way to mass-produce components.
