CNC (Computer Numerical Control): The cornerstone of modern machining. It refers to the automated control of machine tools via a computer executing preprogrammed sequences of commands, ensuring unparalleled repeatability and accuracy.

Tolerances: A critical specification defining the permissible limit of variation in a part's dimension (e.g., ±0.005"). Tighter tolerances demand advanced machining capabilities and meticulous quality control, which we expertly provide for missioncritical components.

3Axis vs. 5Axis Machining: 3axis machines move the cutting tool or part along three linear axes (X, Y, Z). 5Axis Machining adds two rotational axes, allowing complex geometries to be completed in a single setup, reducing lead time and improving accuracy for intricate parts.

CAD (ComputerAided Design) & CAM (ComputerAided Manufacturing): CAD is used to create the 3D model of the part. CAM software then translates this model into the CNC machine code (Gcode). Our integrated CAD/CAM process ensures a seamless transition from your design to a finished component.

Rapid Prototyping & LowVolume Production: The use of CNC machining to quickly produce functional prototypes or small batches directly from digital designs. This is a core strength of our agile service, enabling faster timetomarket for your innovations.

Material Selection: Expertise in machining a wide range of materials—from aluminum and stainless steel to engineering plastics like PEEK—is vital. We guide clients in selecting the optimal material for strength, weight, corrosion resistance, and cost.



Surface Finish: The texture of a machined part, measured in microinches or Ra value. Options include asmachined, bead blasting, anodizing, or powder coating. We offer finishing services inhouse, guaranteeing quality and consistency.

DFM (Design for Manufacturability): Our most valuable service. It involves analyzing your design to suggest modifications that improve manufacturability, reduce cost, and enhance functionality without compromising intent. This collaborative approach builds lasting partnerships.

Mastering this terminology empowers you to specify requirements precisely. At our company, we combine this technical mastery with a fullspectrum service—from expert DFM and precision machining to finishing and global logistics—delivering not just parts, but reliable partnerships and growth for your business. Partner with us for clarity, quality, and a seamless journey from concept to delivery.
