Precision Parts Crafted by Screw Machines
At Specialty Engine Components, our advanced screw machines are the backbone of our ability to produce high-precision, high-volume parts for the automotive industry and beyond. As an IATF 16949-certified machine shop, we leverage this technology to deliver components that meet the tightest tolerances and most demanding specifications. Screw machines excel at creating small to medium-sized parts with exceptional consistency, making them a cornerstone of our manufacturing capabilities. Here’s an overview of the types of parts we craft using this versatile equipment.
Commonly Manufactured Screw Machine Parts
Screw machines are designed to produce intricate parts from metal or plastic rods (bar stock). These machines rotate the material while cutting tools shape it, often completing multiple operations (turning, drilling, threading) in a single setup. The result? Efficient production of complex, cylindrical components with minimal waste and maximum precision. This Manufacturing Process allows us to efficiently churn out a wide range of components, each tailored to your exact needs. Common examples include:
- Transmission Spool Valves: Spool valves in transmissions are typically smaller components with multiple diameters, grooves, and precisely machined surfaces. They slide within a valve body bore to direct fluid/air through ports, requiring exceptional dimensional accuracy and surface finish to ensure smooth operation and minimal blow-by. Screw machines excel at producing these parts efficiently, especially in high volumes for automotive and industrial applications.
- Bushings and sleeves: These cylindrical components guide and support moving/stationary parts within the valve. Screw machines produce them with tight tolerances for inner and outer diameters, often from durable materials of bar stock such as stainless steel.
- Connectors: Designed for valves requiring precise fluid/air delivery, such as in spray or metering applications, screw machines manufacture nozzles and threaded connectors with accurate orifices and fittings.
- Precision Pins and plugs: Small components like retaining pins or sealing plugs, which may be threaded or press-fit, are churned out quickly on screw machines due to their simple yet precise shapes.
- Adapters and Couplings: Threaded fittings, such as adapters or couplings that connect piping systems, are frequently produced on screw machines, leveraging their ability to cut reliable threads in various metals.
- Bushings and Spacers: These small but critical parts maintain alignment or spacing in engines and machinery. Our screw machines craft them with precise inner and outer diameters.
- Shafts: From precision cylindrical shafts to custom threaded shafts, these components are essential for various industrial and automotive applications and are ideal for the screw machining process
- Fittings and Connectors: Hydraulic fittings, and hose connectors that require leak-proof precision, ideal for fluid or gas systems.
- Custom Components: Have a unique design? We specialize in unique one-off parts dedicated to large production volumes, like threaded inserts or specialty engine
components, built to your drawings.
Materials and Finishes
We work with a variety of materials to suit your application, including steel, stainless steel, aluminum, brass, and high-performance plastics. We also can provide components complete with various secondary operations, including various micro finishes to your desired specifications.
Why Screw Machines?
Screw machines shine in high-volume production, delivering repeatability and speed without sacrificing quality. Their multi-spindle capabilities allow us to tackle complex geometries, while automated bar feeders keep production humming. This efficiency translates to cost savings for you, especially over long production runs. Plus, our adherence to IATF 16949 standards means every part undergoes rigorous quality checks, from raw material to final inspection.
