Parts with complex configurations and ones that must securely mate or precisely align with other components are two examples of products for which standard machining practices often prove insufficient. Alternatively, precision machining is a subtractive manufacturing process capable of creating supremely accurate parts with close tolerances. This machining method removes material from a workpiece with a high degree of precision, resulting in a component that falls within a very limited yet acceptable variation range compared to its desired dimensions. Learn more about this manufacturing method and the parts that benefit from it.

Understanding Precision Machined Components & Parts

Compared to parts manufactured with standard machining methods for which looser tolerances might be acceptable, precision machined parts may have tolerances of ±0.0001 inches. Factors like component size, material, complexity, and application will help determine the need for precision machining. For example, stainless steel, titanium, and similarly hard materials or small and intricate parts require precision machining, as do many components for mission-critical applications in industries like aerospace, military/defense, and medical components. Also referred to as close- or low-tolerance parts, tight-tolerance components enable proper functionality and fit with minimal clearance.

Hydraulic Valve Bodies

Precision machining provides a solution for applications requiring parts with intricate inner geometries that will maintain a valve body’s structural integrity. A variety of hydraulic valve bodies require close tolerances in their channel dimensions along with smooth interior surfaces to successfully manage the flow of fluid within a system. Precision machining is ideal for producing globe, ball, and gate valves to fulfill that need. Also, needle, check, and butterfly valves are exposed to pressure during operations, and tight-tolerance manufacturing allows them to seat effectively.

Connectors & Complex Fasteners

Fluid and electrical systems both require connectors machined with accuracy to form tight, dependable connections. Precision machining is the optimal manufacturing choice for creating panel, circular, and coaxial connectors with precision threading to deliver secure transmissions for electronic signals. In complex fasteners, precision machined knurled knobs, threaded barrels, and rivet nuts help assure proper fit.

Actuators & Precision Shafts

Using electrical or pneumatic energy to cause motion in a device, actuators rely on high-accuracy parts to ensure smooth, well-controlled motion without incurring damaging wear. Similarly, components like rotary and pulley shafts require precision machining to generate tight-tolerance parts that will integrate quickly and easily within mechanical systems.

Oil & Gas Fittings

The oil and gas industry requires connectors and hose adapters with precise threads to minimize leaks when these components experience high pressure. Also, as an industry that uses universal fittings that must auto-lock into place quickly and securely, precision machined parts can repeatably achieve the necessary geometries.

Fastening & Joining Components

Fasteners and related components rely on precision machining to enable a secure fit between joined parts, and the process is ideal for creating customized or otherwise non-standard fasteners. For example, bolts possessing uniquely shaped heads must be tight-tolerance parts to meet specialized torque specifications and part fit requirements. Parts that must enable movement, like clevis pins in movable joints, must fit well without actually hindering that motion. Others need accurate inner and outer diameters (ID and OD) to achieve part stability, such as bushings.

Fluid System Components

Tight tolerances are crucial in fluid system parts for safeguarding against leaks and pressure loss. Precision machined flange bolts, pipe couplings, and related fittings enable pipe systems to maintain airtight, reliable seals.

Intricate Small Components

Precision machining is ideal for rod and knurled shafts as it can generate the unique dimensions and patterning that they require to maintain a solid grip. Also, the process can create pin shafts and inserts with exact internal threads, ensuring an appropriate fit.
