CNC Machining is subtractive manufacturing performed on computer-numerically controlled machine tools. Toolpaths generated from CAM drive multi-axis milling, turning, and mill-turn equipment to remove material accurately and repeatably. The approach enables tight tolerances, stable process capability, and scalable automation for prototypes through production across metals and engineering plastics.

Stainless Steel is a group of iron-based alloys containing a minimum of approximately 11% chromium, a composition that prevents the iron from rusting and also provides heat-resistant properties. Different types of stainless steel include the elements carbon (from 0.03% to greater than 1.00%), nitrogen, aluminum, silicon, sulfur, titanium, nickel, copper, selenium, niobium, and molybdenum. Specific additions of nickel and molybdenum enhance corrosion resistance in acidic and chlorine-bearing environments, making it an ideal material for various applications across industries.

CNC Turning uses computer-controlled lathes to rotate bar, billet, or cast blanks while single-point cutting tools remove material. The process excels at producing concentric OD/ID features, tapers, threads, grooves, and complex contours with tight positional accuracy. Modern CNC lathes support live tooling, Y-axis interpolation, sub-spindle part transfer, and bar-feed automation—enabling complete, high-volume production of precision cylindrical components in metals or plastics.

CNC Turning

Large-Diameter CNC Turning focuses on parts whose swing exceeds standard lathe capacity—typically 330 mm (13 in) or more. Specialized heavy-duty spindles and wide-gap beds allow accurate rough- and finish-turning of large flanges, rings, and housings while maintaining concentricity and surface finish comparable to standard CNC turning.

Large-Diameter CNC Turning

Hard Turning in CNC Turning refers to the process of cutting materials that are hard, typically above 45 HRC, using a single point cutting tool. It is an efficient and cost-effective alternative to grinding for achieving precision dimensions and surface finishes on hard materials.

Hard Turning

Precision turning of slender shafts whose length-to-diameter ratio typically exceeds 15:1. Uses between-centres support (live/dead centres, programmable steady rests) and vibration-damped tooling to maintain ≤0.05 mm TIR over metre-scale workpieces. Typical applications include power-generation rotors, down-hole drilling mandrels, aerospace actuators, and automotive drive shafts.

Long-Shaft CNC Turning

Swiss Machining is a high-precision CNC machining process designed for producing small, complex parts with tight tolerances. It is typically performed on Swiss-type lathes, which utilize a sliding headstock and a guide bushing to minimize deflection and enhance precision during various machining operations, including turning, milling, and drilling. Key features include high precision and accuracy, capability for multiple operations, and minimal tool deflection. Common applications include medical devices, aerospace components, precision instruments, and electronics parts.

Screw Machining is a high-speed, precision machining process designed for the mass production of small, intricate components such as screws, bolts, and other threaded parts. Performed on automatic screw machines, it allows for multiple operations—including turning, threading, drilling, and knurling—in quick succession. This ensures efficient and accurate production of high-volume parts. Typical applications include automotive components, medical devices, electronics hardware, and various fasteners or fittings.

Prototyping is the creation of preliminary parts or models that simulate the form, fit, and function of a product prior to mass production. It is used to validate design intent, test material performance, assess manufacturability, and gather stakeholder feedback. Prototyping methods include subtractive (e.g., CNC machining), additive (e.g., 3D printing), and formative (e.g., soft tooling or urethane casting) approaches depending on the functional and aesthetic requirements of the part.
