Twin-Spindle CNC Mill-Turn Machine for Precision Part Machining

Product Overview

The 16-Station Electric Spindles CNC Mill-Turn stands as a high-performance solution engineered for precision manufacturing, leveraging advanced technology to handle complex machining tasks with unparalleled accuracy. Equipped with the FANUC Oi-TF CNC Control System—a cornerstone of reliability in industrial automation—this machine excels in producing intricate components across aerospace, medical, and automotive sectors. Its robust design supports a maximum swing diameter of Ø 600 mm and a main spindle machining capacity of Ø 320 mm, making it versatile for both large workpieces and detailed parts. With dual spindles (main and sub) operating at 4500 RPM, paired with a 16-station turret, it eliminates the need for multiple setups, streamlining production and reducing cycle times. Whether tackling long turning lengths (up to 510 mm + 40 mm with back tooling) or precise milling operations (up to 550 mm), this machine delivers consistent performance for high-volume and high-precision applications.

Design

The 16-Station Electric Spindles CNC Mill-Turn integrates durability and precision into its core design, starting with THK ball screws and guides—renowned for low friction and high rigidity—paired with Japanese imported bearings to ensure transmission accuracy. This combination reduces wear and tear, extending the machine’s service life while maintaining consistent performance. The dual-spindle layout (main and sub) enables parallel machining, doubling throughput by processing two workpieces simultaneously. Its 16-station turret is engineered for high rigidity, supporting heavy-duty milling of complex parts without compromising precision. The compact footprint (2900×1900 mm) is optimized for factory floors, while the robust 5500 kg structure dampens vibrations—critical for achieving tight tolerances in high-speed operations. Every design element, from the coolant system (260 L capacity) to the tooling setup, is tailored to minimize downtime and maximize efficiency, making it a cornerstone of modern precision manufacturing.

1. Component processing for semiconductor manufacturing equipment

Semiconductor production equipment (such as lithography machines, etching machines, thin film deposition equipment, etc.) requires a large number of high-precision, high-cleanliness components, and CNC machine tools are crucial in the manufacture of such components.

Reaction chambers and vacuum components: Processing high-temperature-resistant, corrosion-resistant metals (such as aluminium alloys, stainless steel) or ceramic chambers to ensure sealing and surface finish.

Precision fixtures and carriers: Fixtures used for wafer transfer and positioning require micron-level precision to prevent contamination or displacement.

Gas/liquid piping systems: Processing complex flow channels and interfaces to ensure leak-free operation and precise fluid control.

2. Moulds and components for packaging and testing processes

Lead frame moulds: Processing stamping moulds for lead frames used in chip packaging, where precision directly impacts pin alignment and electrical performance.
