From our Houston, Texas, facility, our team supports CNC machining, EDM, production work, materials guidance, and inspection with the experience needed to manufacture parts to specification. --- # Machining Support for Complex, High-Tolerance Parts ![Call-Image-Side-Text-Precision-Parts-675x675](https://www.owsimanufacturing.com/hs-fs/hubfs/Call-Image-Side-Text-Precision-Parts-675x675.jpg?width=675&height=675&name=Call-Image-Side-Text-Precision-Parts-675x675.jpg "Call-Image-Side-Text-Precision-Parts-675x675") Precision machining starts with understanding the part. OWSI works with customers to review specifications, machining requirements, and production needs before work begins, bringing engineering input into the process early so each part is matched with the right process and quality expectations from the start.   This type of work can involve:   - Tight-tolerance requirements - Complex part geometries - Drawing review and engineering input - Prototype, small-batch, or production machining - Material and application considerations - Quality-focused planning to help reduce scrap ## CNC Machining and EDM OWSI supports CNC machining for parts that require accuracy, consistency, and careful attention to the drawing. Our capabilities include CNC turning and milling, 5-axis machining, Swiss machining, horizontal and vertical machining, and automated production processes.   From prototypes and small batches to repeat production, our team works to match each part with the right equipment, programming approach, and manufacturing process. For ongoing production needs, we focus on establishing a dependable process that can maintain part quality and dimensional consistency across repeat runs.   ![OSWI-CNC-Turning](https://www.owsimanufacturing.com/hubfs/OSWI-CNC-Turning.jpg) #### CNC Turning **CNC Turning** CNC turning for round or cylindrical components that require consistent dimensions and accurate features.  ![OSWI-CNC-Milling](https://www.owsimanufacturing.com/hubfs/OSWI-CNC-Milling.jpg) #### CNC Milling **CNC Milling** CNC milling for parts with detailed features, precise surfaces, and dimensional requirements. ![OSWI-5-Axis-Machining](https://www.owsimanufacturing.com/hubfs/OSWI-5-Axis-Machining.jpg) #### 5-Axis Machining **5-Axis Machining** 5-axis machining for complex parts that require multiple angles, tight access, or fewer setups. ![owsi-Swiss-Screw-475x563](https://www.owsimanufacturing.com/hubfs/owsi-Swiss-Screw-475x563.jpg) #### Swiss Machining **Swiss Machining** Swiss machining for small, detailed components that require precision and repeatability.  ![OSWI-Vertical-Machining-DVF-6500-675x800](https://www.owsimanufacturing.com/hubfs/OSWI-Vertical-Machining-DVF-6500-675x800.jpg) #### Horizontal & Vertical Machining **Horizontal & Vertical Machining** Horizontal and vertical machining options for a range of part sizes, geometries, and production requirements.  ![OSWI-WIre-EDM-675x800](https://www.owsimanufacturing.com/hubfs/OSWI-WIre-EDM-675x800.jpg) #### Wire EDM **Wire EDM** Wire EDM support for precise cuts, detailed profiles, and features that require tight control.  ![owsi-Plundge-475x563](https://www.owsimanufacturing.com/hubfs/owsi-Plundge-475x563.jpg) #### Plunge EDM **Plunge EDM** Plunge EDM for shapes, cavities, or features that may be difficult to machine through conventional methods.  --- ## **CAD/CAM & Programming Support** Programming plays an important role in how machining work moves from drawing to production. OWSI uses CAD/CAM support to review part geometry, plan machining steps, and help create a process that fits the part before it reaches the machine.   This helps our team think through the work early, especially when a part involves complex features, tight tolerances, or specific production requirements. Our programming support includes tools such as GibbsCAM, Mastercam, FeatureCAM, SolidWorks, and AutoCAD. ![OSWI-CAD-CAM-&-Programming-750x500](https://www.owsimanufacturing.com/hubfs/OSWI-CAD-CAM-%26-Programming-750x500.jpg "OSWI-CAD-CAM-&-Programming-750x500") ![OSWI-Production-Machining-750x500](https://www.owsimanufacturing.com/hubfs/OSWI-Production-Machining-750x500.jpg "OSWI-Production-Machining-750x500") ## **Production Machining** OWSI supports production machining for prototypes, small batches, repeat parts, and ongoing manufacturing programs. Once a part is ready for production, our team can establish a repeatable process designed to support accuracy and dimensional consistency across production runs.   For qualified production work, robotic and lights-out machining can help support repeatability and efficiency. OWSI also maintains automatic screw machine capabilities for suitable repeat components. ## **Materials Expertise for Demanding Applications**   Materials can shape nearly every part of a machining job, from the tooling and programming approach to the inspection requirements and final application. OWSI works with customers to understand material considerations before production begins, especially when the part will be used in a demanding environment.   This is especially important for aerospace-related parts and other demanding applications where material behavior, machinability, and inspection requirements can shape the production approach. Our team can support conversations around machinability, part function, and production requirements so the material is considered as part of the manufacturing plan, not as an afterthought.   That practical knowledge helps us identify potential issues earlier and support a more consistent path through machining and inspection. ![OSWI-Materials-Expertise-750x500](https://www.owsimanufacturing.com/hubfs/OSWI-Materials-Expertise-750x500.jpg "OSWI-Materials-Expertise-750x500") ![OWSI-Quality-Control](https://www.owsimanufacturing.com/hubfs/OWSI-Quality-Control-750x500.jpg "OWSI-Quality-Control") ## **Quality Control & Inspection** Quality control is part of how OWSI approaches precision machining from the start. Our team reviews part requirements, follows defined processes, and uses inspection resources to confirm that finished parts meet the specifications provided. For aerospace-related work and other demanding applications, this level of documentation and inspection support can be an important part of the supplier review process. Our quality and inspection process supports:   - Specification review before production begins - In-process checks where needed - Final inspection of finished parts - Documentation tied to customer requirements - Consistent production and inspection practices - Compliance with ISO 9001:2015 quality standards   For customers, quality is not treated as a final step only. It is part of the work from planning through production, helping support parts that are made accurately and consistently. --- ![OWSI\_property](https://www.owsimanufacturing.com/hs-fs/hubfs/OWSI_property.jpg?width=2000&height=1125&name=OWSI_property.jpg "OWSI_property") **Explore OWSI’s Equipment & Facility**     At OWSI, our capabilities are supported by more than 30,000 square feet of climate-controlled manufacturing space in Houston, Texas.
