Brass Screw Machine Parts
Brass Screw Machine parts are precision components produced on high-speed automatic or CNC screw machines, ideal for tight-tolerance, repeatable geometries. Owing to Brass’s excellent machinability, corrosion resistance, and electrical conductivity, these parts are widely used in electrical, plumbing, automotive, electronics, and industrial assemblies. Typical products include inserts, terminals, bushings, pins, studs, and fasteners, manufactured efficiently for both medium and high-volume requirements.

Screw Machining of Brass
Screw machining of Brass is a highly efficient subtractive manufacturing process where bar stock is fed into automatic or CNC screw machines to produce complex parts at high speed. Brass alloys allow faster spindle speeds, cleaner chip formation, and superior surface finish compared to many other metals. This makes screw machining of Brass particularly suitable for mass-produced precision components with consistent dimensional accuracy and minimal tool wear.

Free Cutting Brass Machined Parts
Free cutting Brass machined parts are typically made from alloys such as C36000 or CW614N, which contain lead or lead-free additives to enhance machinability. These alloys reduce cutting forces, improve surface finish, and enable very tight tolerances at high production rates. Free cutting Brass parts are commonly used in electrical connectors, plumbing fittings, instrumentation components, and threaded inserts where precision and productivity are critical.

CNC Turning Brass Components
CNC turning Brass components involves the use of computer-controlled lathes to produce highly accurate, repeatable parts with complex profiles. Brass’s stability during machining allows excellent concentricity, fine threads, and smooth finishes without secondary operations. CNC-turned Brass parts are widely used in aerospace sub-assemblies, electronics, fluid control systems, and precision engineering applications requiring consistent quality.

Brass CNC Machined Screw Machine Parts
Brass CNC machined screw machine parts combine the productivity of screw machining with the flexibility of CNC control. This approach allows rapid changeovers, tight tolerances, and complex geometries while maintaining high output. Such parts are ideal for OEMs requiring precision Brass components in large volumes with strict dimensional and performance requirements.

Swiss Machined Parts of Brass
Swiss machined parts of Brass are produced on Swiss-type lathes that support the workpiece close to the cutting zone, enabling extreme precision for small-diameter, long, or intricate components. Brass’s machinability makes it particularly well-suited for Swiss machining, resulting in excellent surface finish and dimensional control. These parts are commonly used in medical devices, electronics, sensors, and high-precision mechanical assemblies.

C36000 Brass Parts
C36000 Brass parts, also known as free-cutting Brass, are among the most widely used machined Brass components globally. This alloy offers unmatched machinability, good strength, and reliable corrosion resistance, making it ideal for high-speed screw machining and CNC turning. C36000 Brass parts are extensively used in electrical connectors, fasteners, plumbing fittings, and precision industrial components.

Material Grades & International Standards

We machine a comprehensive range of Brass alloys, each selected for specific property advantages. Our engineers ensure compliance with relevant global standards.

Manufacturing Processes & Machinery

Our production of precision Brass components utilizes a strategic blend of automated processes. CNC Turning Brass components is performed on modern, multi-axis CNC lathes equipped with live tooling and bar feeders, allowing for complete machining of complex geometries—including off-center drilling, milling, and tapping—in a single setup. This is crucial for maintaining concentricity and reducing lead times. For parts with very high length-to-diameter ratios or extreme tolerances, we employ Swiss machining of Brass on CNC Swiss-type automatic lathes. This process provides exceptional stability and precision by guiding the bar stock through a bushing close to the cutting tools. For the highest volume orders of simpler geometries, our multi-spindle screw machines offer unparalleled speed and economy in producing free-cutting Brass machined parts. All our machinery is regularly calibrated and maintained, and our programming team uses advanced CAM software to optimize tool paths, minimize cycle times, and ensure material efficiency for every custom Brass Screw Machine job.

Typical Parts Produced & Industries Served

The versatility of Brass screw machining makes it indispensable across a wide spectrum of industries. Typical Brass CNC machined Screw Machine parts we produce include:

• Electrical & Electronics: Precision terminals, connector pins, socket contacts, and relay components leverage Brass’s superior electrical conductivity.

• Plumbing & Fluid Handling: Compression fittings, valve stems, pump impellers, and regulator parts utilize Brass’s corrosion resistance and machinability.

• Automotive: Fuel system components, sensor housings, bushings, and decorative emblems.

• Medical Devices: Orthodontic brackets, surgical instrument components, and pneumatic fittings (in specified, medical-safe alloys).

• Consumer Hardware: Precision screws, nuts, knobs, fasteners, and locking mechanisms.

Technical Specifications: Tolerances, Finishes & Performance

We adhere to stringent quality protocols to ensure part-to-part consistency. Standard machining tolerances for our Brass turned parts are ±0.005″ (0.127mm) for diameters and ±0.010″ (0.254mm) for lengths, with significantly tighter tolerances achievable upon request for critical dimensions. Swiss machined parts of Brass can routinely hold tolerances as tight as ±0.0005″ (0.0127mm). A variety of plating and finishing options are available to enhance performance or aesthetics, including:

• Electroplating: Nickel, Tin, Silver, or Chrome plating for wear resistance, solderability, or corrosion protection.

• Passivation: Chemical processes to enhance the natural corrosion resistance of the Brass surface.

• Polishing/Buffing: For a bright, decorative finish on visible components.

Performance Metrics: C36000 Brass parts typically exhibit a tensile strength of 58-65 ksi (400-450 MPa) and a machinability rating that sets the standard for free-cutting materials. This results in faster production speeds, lower power consumption, and the ability to achieve superior surface finishes directly off the machine.
