Aluminum CNC Turning Center

Product Specifications

Technical details and manufacturing context for Aluminum CNC Turning Center

Definition

A computer numerical control (CNC) turning machine specifically engineered for aluminum machining operations. This industrial device performs rotational cutting operations on aluminum billets, bars, or castings to create cylindrical parts with high dimensional accuracy. It features specialized tooling and coolant systems optimized for aluminum's material properties, including high thermal conductivity and softness. The machine is commonly used in automotive, aerospace, and electronics manufacturing for producing aluminum shafts, connectors, and housings. The base is typically cast iron, with steel guideways, aluminum covers, and polycarbonate windows for visibility. Key parameters include a maximum turning diameter of 200–400 mm, maximum turning length of 300–1000 mm, spindle speed range of 50–6000 rpm, and 8–12 tool stations. Positioning accuracy is ±0.005–±0.01 mm, and repeatability is ±0.003–±0.005 mm, both per ISO 230-2. Spindle motor power ranges from 5.5–15 kW, rapid traverse rate is 20–30 m/min, and maximum workpiece weight is 100–500 kg. The machine weight is 3000–8000 kg, with an operating temperature range of 5–40 °C per ISO 230-3. Coolant system capacity is 100–200 L. CNC control systems may be Siemens 828D or Fanuc 0i-TF, and power supply is 380 V ±10%, 50 Hz per IEC 60038. These values are reference ranges; verify model-specific specifications with the legal manufacturer or supplier.

Working Principle

The machine rotates the aluminum workpiece at a controlled speed while stationary cutting tools remove material to achieve the desired cylindrical geometry. The spindle holds the workpiece via a chuck, and the turret indexes tools into position. Coolant is applied to manage heat and chip evacuation. The CNC control coordinates axis movements and spindle speed based on programmed instructions, ensuring precise dimensions and surface finish.
