The M32 CNC Sliding Head is Citizen’s flagship sliding head model, built for high-end, complex machining performance.
It features redesigned covers for better access and a new NC unit with a responsive touch-panel HMI. The upgraded control panel improves usability, helping operators work more efficiently and intuitively.
Structural analysis optimized the machine’s rigidity, balancing strength and weight for stable, high-precision cutting. The turret system uses a new single-drive design with higher-power rotary tools for greater machining capability.
The M32-VIII includes a programmable B-axis for full five-axis contouring on the main or sub spindle. Adjustable-angle back spindle toolholder to support advanced machining with the Y-axis. This allows greater flexibility in process planning and improves simultaneous front and back machining.
A high-output 5.5/7.5 kW spindle motor powers both front and back spindles.
The M32-V/VIII supports guide-bush and non-guide-bush modes for different production needs. A 38mm oversize option expands the application range for larger-diameter components.
LFV technology comes standard, improving chip control, reducing swarf, and extending tool life in demanding materials.
