This article provides a detailed overview of the machine’s capabilities, features, specifications, and advantages, highlighting its role in modern manufacturing environments.

Key Features of the Citizen Cincom A220-VII PL

1. Multi-Axis Turning

The A220-VII PL utilizes advanced multi-axis capabilities to perform intricate turning operations with superior precision. The machine integrates a combination of up to 7 axes (main spindle, sub-spindle, and tool turret) for full-contouring functionality, enabling the production of complex parts in a single set-up. This reduces cycle time and ensures high repeatability.
• Main Spindle: Features high-speed, high-torque capabilities for efficient material removal.
• Sub-Spindle: Allows backworking operations, enabling complete machining of parts without re-chucking.
• Tool Turret: Equipped with multiple tools, enabling simultaneous machining operations to increase productivity.

2. High-Speed and High-Precision

Equipped with cutting-edge technology, the Cincom A220-VII PL is engineered for fast cycle times and high-precision work. The machine’s powerful spindle motor and advanced control systems ensure stability during high-speed machining, while maintaining tight tolerances, even with difficult-to-machine materials.
• Spindle Speed: Up to 10,000 RPM for efficient turning and high-quality surface finishes.
• Repeatability: Exceptional accuracy with a positioning accuracy of ±0.002 mm and a repeatability rate of ±0.001 mm.

3. Flexibility for Complex Parts

The A220-VII PL is versatile in terms of the variety of parts it can handle. With the ability to perform multiple operations such as turning, drilling, milling, and tapping, the machine is suitable for producing a wide range of complex components, including precision parts with fine threads, intricate contours, and tight radii.

4. Integrated Sub-Spindle and Backworking

A key feature of the A220-VII PL is its integrated sub-spindle system, which allows operators to perform backworking on the part while it is being held by the main spindle. This configuration enables the machine to complete a part in fewer operations and with higher accuracy. The use of sub-spindles also facilitates the machining of parts with deep grooves or multiple machining steps, increasing overall production efficiency.
