CNC (Computer Numerical Control): The cornerstone of modern machining. It refers to the automated control of machine tools via a computer executing preprogrammed sequences, ensuring unmatched repeatability and precision in every part we produce.

Tolerance: A critical specification defining the permissible limit of variation in a part's dimension. Tighter tolerances demand advanced machining capabilities, an area where our shop excels to meet exacting international standards.

Axis: Describes the direction of movement of a cutting tool or workpiece. Basic machines operate on 3 axes (X, Y, Z), while our multiaxis setups enable complex geometries in a single, efficient setup, reducing lead times and cost.

CAD/CAM: ComputerAided Design (CAD) is for creating digital 2D or 3D models. ComputerAided Manufacturing (CAM) software then translates these models into machinereadable code (Gcode). Our integrated CAD/CAM workflow streamlines prototyping and production.

Milling: A subtractive process where rotary cutters remove material from a stationary workpiece. Ideal for creating slots, holes, and intricate contours.

Turning: Performed on a lathe, this process rotates the workpiece while a stationary cutting tool shapes it, perfect for producing cylindrical components like shafts and bushings.



Surface Finish: The texture of a machined surface, measured in microns (µm) or microinches (µin). Options like asmachined, beadblasted, or anodized affect both function and aesthetics, and we provide comprehensive finishing services.

Rapid Prototyping: The fast fabrication of a physical part directly from CAD data. Our CNC machines enable rapid, highprecision prototypes, allowing for swift design validation before fullscale production.

Workholding: The method of securing the workpiece (using vises, chucks, or custom fixtures). Proper workholding is vital for accuracy and safety, and we employ optimal solutions for every project.

Gcode: The programming language that instructs CNC machines on tool movement, speed, and path. Our expert programmers optimize Gcode for maximum efficiency and tool life.
