What Are Precision Machined Metal Parts?

Precision machined parts often require intricate features and require precise specifications. These parts may include threads, holes, grooves, or tapers that must provide an exact fit with other components.

Precision machining is typically used to produce metal parts that require precision for the product to function properly. For example, the components that make up an automobile engine require precise specifications for optimal performance.

There is less room for error, requiring machinists to use specialized equipment for a closer tolerance. By using computer numerically controlled machines (CNC machines), lathes, and presses, our team manufactures a wide range of intricate metal parts that require keen attention to detail.

The Precision Machining Process

The precision machining process often starts with an initial sketch, which is rendered using computer-aided design (CAD) software. Engineers use CAD software such as AutoCAD to create a 3D diagram of a hand-drawn sketch.

Machinists may then enter the design into computer-aided manufacturing (CAM) programs or CNC machines. Computers automate the removal of material to produce precise parts.

Precision machining processes allow for greater accuracy. Each cut is completed by a machine that receives instructions from the computer software.

The machines can carry out precise cuts with limited margins of error. This results in increased repeatability. You can continue to produce thousands of the same parts with identical specifications and tolerances down to 0.01-0.05mm.

Uses for Precision CNC Machined Parts

Precision machining is a vital part of the production of components that you likely use every day. The auto, electrical, electronics, medical, and aerospace industries all rely heavily on precisely machined parts to produce products that meet quality and safety standards.

Precision machining can be used to design tools, parts, custom fasteners, and other essential hardware. These parts require a tighter tolerance to ensure a proper fit with other components.

Precision machining is also useful as a means of maintaining consistency when mass-producing components. This is especially common when producing things like fittings. Precision machined parts manufacturers ensure repeatable, consistent results.

Precision machining can also be used for finishing metal products. For example, you may use precision machining to finish parts produced through die casting or other less accurate fabrication methods.

Restoration work is another use for precision machining. Over time, worn parts may need welding, grooving, or calibration. Computer-aided equipment can help restore the parts to their original condition.

Why Choose Precision CNC Machined Parts for Your Project?

At The Federal Group USA, our precision machining services are available for a wide range of applications, including secondary and finishing work.

Some of the benefits of precision machining include:

  • Greater accuracy
  • Increased repeatability
  • Increased efficiency
  • Reduced material waste
  • Time savings

Manually cutting or using a die-casting process often results in greater variance in the final dimensions or surface of fabricated parts. Components may not fit together perfectly, limiting the function of the product.

Precision machining provides greater efficiency and less variance compared to other metal fabrication methods that involve more manual input. Computer-aided machines operate faster than human-operated machines while producing fewer errors, saving time, and reducing material waste.

Commonly Used Precision Machining Processes

Precision machining is what is known as a subtractive process. We use specialized software and equipment to remove material to create parts that match your specifications.

The equipment and tools used to machine precision parts are often used in conjunction with CAD and CAM programs. Engineers use these programs to create “digital blueprints” that can then be read by the precision machining tools. This allows for various milling machines, lathes, and grinders to intricately remove the material with a greater level of accuracy compared to human-operated machines.

Common processes and machines for precision machined components include:

At TFG USA, we use three-axis, four-axis, and five-axis CNC milling machines. These machines allow us to produce complex shapes and perform milling from any angle.

With a lathe, the workpiece is rotated against a cutting tool. As with the milling machines,  lathes receive instructions from a computer program, producing parts with diameters from 0.062 inches to 22 inches.

Swiss screw machines are also used for precision machining processes. The original Swiss machines were designed to produce the intricate components needed for Swiss watches. The workpiece secures to a sliding headstock and rotates around a spindle while a cutting tool trims the part to the desired specifications.
