Mill-turn machining technology is particularly suitable for processing parts with complex structures, high precision requirements, and those that require multiple processes to be completed in a single setup. Its core advantage lies in improving machining accuracy and efficiency by reducing the number of setups.
Complex Rotary Parts
These parts typically have rotational features (such as disc-like structures) and include complex non-rotational surfaces or hole systems, such as turbine discs, impellers, and gas turbine blades in aero engines. Turning and milling composite machining can complete multiple processes in a single setup, including turning the outer diameter, milling the blade profile, and drilling holes, avoiding positioning errors caused by multiple setups. This is especially suitable for processing difficult-to-machine materials such as titanium alloys and high-temperature alloys.
Precision Shafts and Irregularly Shaped Structural Parts
- Precision Shaft Parts: Such as automotive drive shafts, motor shafts, and crankshafts, which require extremely high coaxiality and surface roughness. Turning and milling combined machining, through synchronous or alternating processing, can complete rough turning, finish turning, milling keyways, and drilling center holes in a single setup, significantly improving positional accuracy.
- Irregularly Shaped Structural Parts: Including irregularly shaped parts such as medical implants (e.g., artificial joints), precision molds, and missile casings. Its multi-axis linkage capability allows for flexible machining of complex features such as curved surfaces, holes, and grooves, without the need to change equipment or fixtures.
High Value-Added Small Parts and Industry Applications
High-value-added small parts: Such as watch parts, miniature sensor housings, and optical lens barrels, which are small in size but require micron-level precision. The high-rigidity spindle and precision guide rails of the turn-mill composite machine ensure processing stability, while reducing the scrap rate through single-setup machining.
Industry Application Expansion:
Aerospace: Machining engine fuel nozzles, aerospace structural components, etc., meeting the high-precision thin-walled part requirements.
Automotive Manufacturing: Used for mass production of parts such as turbocharger rotors and gearbox gear shafts, shortening production cycles.
Medical Devices: Machining biocompatible material parts such as artificial joints and dental implants, with surface roughness controllable to below Ra 0.8μm.
Energy and Mold Making: Suitable for large or complex cavity parts such as nuclear power valves and injection mold cores, enabling deep hole and multi-axis linkage machining.
