The World's Fastest 32mm CNC Sliding Head!

The Citizen A32-VII offers 32mm large-diameter machining at an unbeatable low price. Although inexpensive the machine is strong, powerful and rigid giving it exceptional cutting performance making it ideally suited to heavy machining.

 

With features like a rapid feed rate of 45m/min, high speed processing with the latest NC unit, and Citizen's unique Cincom Control technology, it achieves 30% higher productivity than previous machines. To maintain consistent high-accuracy machining the design takes thermal displacement into account carefully considering factors such as the shape of the bed and the placement of the electrical cabinet.

 

As standard the machine is equipped with 7 axes, 6 turning tools, 4 rotary tools for cross-machining, 9 tools for back-end machining and 5 tools for front-end machining giving a total of 23 tools allowing great flexibility. Many different tooling configurations are available to tailor the machine to your requirements.

 

Maximum cutting length is 320mm in one chucking. However, with the optional long work piece unit, components up to 600mm can be machined.

 

The main spindle is driven by a 5.5 / 7.5 kW motor and the sub-spindle has a 2.2 / 3.7 kW drive. The rotary tool drive also has a 1 kW, AC spindle motor with a maximum speed of 5,000RPM. Rapid traverse rate is increased to 45m/min for a large reduction in idle time from previous models.

 

Comprehensive standard equipment, space-saving design, easy operation, low running costs and high productivity - all at an extremely attractive price makes the A32-VII an must-have purchase for both newcomers to sliding head and existing users looking to increase their capacity.

Work Area

Vertical Tool Holder

  • 4 rotary cross-drilling / milling spindles and 6 turning tools fitted as standard for turning, grooving, screw-cutting, parting-off etc.

  • Of the 4 rotary spindles:

    • 2 are ER16 (1kW, 5000rpm)

    • 1 is ER20 (half-speed, double torque, max 2500rpm)

    • 1 is Quill-type ER16 (for fast changeover to live end working options).

End Working Holder 1

  • Standard: 4 fixed stations for front machining and 4 fixed stations for back machining

  • Option 1: Additional 2 front / 2 back (giving 6 front / 6 back in total)

  • Option 2: Additional 6 driven tools for front and back machining (5,000rpm / 1kW)

End Working Holder 2

  • Standard: 5 end working positions. 4 out of the 5 can be utilised for either live or fixed end working. ER20 Max 5,000rpm, 1KW

CNC System

The Mitsubishi M70 series control provides super-fast NC processing to greatly increase productivity.

 

The complete control system is integrated into the swiveling operation panel which incorporates a clear 10.4" LCD colour display.

 

The CNC hand wheel enables safe and easy program prove out. Potential collision points can be recognised and avoided, and all movements can be optimised. Through the clear user interface and the extensive range of functions, programming is simplified to enable a fast-track learning curve even for first time users.

 

This latest-generation control has improved startup and shutdown times and a more responsive feel than the previous generation.

 

The storage and input of program data is simplified by the CompactFlash memory card slot.

 

Citizen's renowned ease of use helps operators achieve fast changeovers.

 

Automatic program convert function automatically converts programs written for the A20-VII and L32-VII to the A32-VII.
