Sliding Head LFV Technology

Cincom A20-VII CNC Sliding Head
Precision, Simplicity, and Versatility

The A20-VII is a compact, high-performance 5-axis CNC sliding head machine that delivers exceptional value through precision, flexibility, and ease of use. Designed for efficient small-part machining, the A20 is ideal for manufacturers looking to reduce costs without compromising performance.

A key feature is its ability to switch between guide bush and non-guide bush modes, making it highly adaptable for both long and short components. This flexibility helps reduce material waste and streamlines setup, especially when working with shorter bar lengths.

The A20 also features Citizen’s proprietary LFV technology, which improves chip control, enhances surface quality, and extends tool life. LFV significantly reduces swarf build-up, ensuring more stable, uninterrupted machining—even on challenging materials.

Increase productivity. The A20 includes live tooling on the back tool post, enabling efficient front and rear machining in a single setup. With support for bar diameters up to ø25mm, the A20 expands your capability across a wider range of applications.

What truly sets the A20 apart is its simple, intuitive operation. The machine is equipped with a modern, user-friendly control interface that combines advanced functionality with a clean, easy-to-navigate layout. Operators of all skill levels will appreciate its straightforward programming, fast access and clear visualisation of machining processes.

Whether you’re scaling up production or running high-precision batches, the Citizen A20 CNC Sliding Head offers reliable performance, smart control and flexible features, all in a machine that’s easy to operate and built to last.
