At Buell Automatics, we offer computer numeric control (CNC) machining services for the design and manufacture of high-precision metal parts and components. Ideal for intricate and complex designs, our precision CNC machining services are continually expanding in order to better serve our diverse client pool.

Buell’s late model equipment is regularly updated and meticulously maintained to ensure optimized production, whether our clients require prototype, low-volume, high-volume, or blanket orders. Making use of automatic bar feeders, our team is currently running Citizen Swiss Turning machines and Miyano BNA-42MSY machines.

We can run material of almost any length up to 1.65 inches (42 mm) in diameter, with tolerances of .0001 inch. Common materials include:

  • Stainless steel
  • Aluminum
  • Brass
  • Bronze/Copper
  • Carbon Steels
  • Alloys
  • Plastics

Why Precision Machining

Manufacturers use precision CNC machining to create assembly components used in the design of more complex precision equipment and machinery. It creates complex, tight tolerance, and repeatable parts used for industrial, commercial, aerospace and medical fields to name a few. Because it relies on automated processes, based on preprogrammed computer-aided design (CAD) software, CNC machinery can achieve, and consistently hold, very tight tolerances because there are fewer opportunities for human error.

In the simplest terms, 5-axis machining involves programming a computer to move a part or cutting tool along multiple axis simultaneously or independently, enabling the creation of very complex parts.

CNC machining combines computer-controlled precision with human-engineered design. These processes work well for projects that require excellent repeatability no matter the production run’s size.

CNC Tools and Materials

Precision machining is a subtractive process that uses custom software, engineered tools, and process movements to create fine-featured products in many types of materials. It follows instructions provided by the program setup, using computer-aided manufacturing (CAM) programs, and the blueprints, to enhance its ability to build accurate components.

There are a number of materials that can be used in precision CNC machining. Some of the most common are:

  • Aluminum
  • Brass
  • Copper
  • Steel
  • Stainless steel
  • Alloys
  • Plastics
  • Aluminum alloys

Many of our machines are programmed to operate via CNC technology, including:

  • Milling machines
  • Lathes
  • Plasma cutters
  • Electric discharging machines (EDI)
  • Saws
  • Grinders

CNC Aluminum

Aluminum used for CNC machining come in many different grades, and each of which has unique characteristics and uses. A few of the most prevalently used aluminum alloys include:

Aluminum 2011

One of the most popular screw machine stock alloys available. T3 temper offers excellent machinability and surface finish. The Aluminum’s T3 tempers chip are well known for being small in size. Typically used in connectors and fittings, brake pistons, computer parts, knobs and meter shafts.

Aluminum 6061: Lead free

A medium-strength alloy that offers improved corrosion resistance, aluminum 6061 contains magnesium and silicon, which improve its formability and weldability. Common applications include uses in electronic hardware, aircraft fittings, and camera lens mounts.

Aluminum 7075

Lead free, higher strength than aluminum 6061 and has good fatigue strength. It can be machined to build gears, shafts, missile parts, regulating valve parts, keys, and bike frames.
