Conventional Milling and Turning
Machining forms the cornerstone of modern manufacturing, combining precision with versatile applications. In the context of conventional methods—milling anturning—the synergy between the operator’s expertise and the capabilities of traditional machines is paramount.
At MDP Precision, we specialize in conventional machining techniques—milling and turning—which, despite advancements in CNC technology, remain critical for prototyping, low-volume production, and components requiring a tailored approach.
Metal Machining – Conventional Milling
Conventional milling relies on the relative rotary motion of the tool (milling cutter) against a stationary or linearly moving workpiece. Unlike CNC machining, where tool paths are pre-programmed, in conventional methods, the operator manually controls cutting parameters such as spindle speed (up to 10,000 RPM for universal milling machines), depth of cut (adjustable from 0.1–5 mm depending on material), and feed rate (typically 0.05–0.3 mm/rev).
Complex geometries are achieved through coordinated movements in three axes (X, Y, Z) with manual adjustments to the milling table’s position. Typical operations include:
Face Milling: For machining flat surfaces using cylindrical face mills.
Profile Milling: For creating grooves, threads, or curved contours using ball or tapered mills.
Peripheral Milling: Applied in the machining of gears and components with complex lateral geometries.
Metal Machining – Conventional Turning
Conventional turning, performed on turret or center lathes, focuses on machining rotational solids through a combination of the workpiece’s rotary motion and the linear feed of the cutting tool.
Industrial applications include:
- External Turning: Reducing the diameter of shafts or sleeves.
- Internal Turning: Machining bores or internal threads.
- Copy Turning: Replicating shapes using templates.
