The document provides an overview of the Citizen M32 Sliding Headstock CNC Automatic Lathe, highlighting its advanced features, configurations, tooling options, control systems, and specifications.
Machine Overview

The Citizen M32 is a market-leading, compact CNC automatic lathe designed for high productivity, flexibility, and tool capacity, with a focus on simultaneous multi-tool machining.
The next-generation model enhances capabilities with additional axes: a Y3 axis on the back tool post (up to 9 tools, including 6 driven) and a B axis on the gang tool post for 4-axis simultaneous control.
Multiple configurations are available, including types V, VII, and VIII, offering options for Y2, Y3, and B axes, with the VIII model providing full programmability of all axes and rotary tools.
The machine's turret design maintains compatibility with previous models, with improvements like an extended Z2 axis stroke for opposed turning and cross drilling, reducing cycle times.

Tooling and Accessories

The lathe supports diverse tooling options, including fixed sleeve holders, drilling spindles, cross drilling spindles, and multi-sleeve holders, enabling complex machining such as slant holes, cross drilling, and contouring.
Tooling can be mounted in various positions, with options for multiple sleeves, rotary tools, and programmable angles, facilitating endless machining possibilities.
Optional attachments include workpiece unloaders, chip conveyors, long workpiece devices, and signal towers, enhancing automation and efficiency.

Operational Features

The machine employs the latest high-speed CNC control system, “Cincom Control,” which reduces cycle times and power consumption through optimized axis motion, energy-saving functions, and quick program checks.
On-machine program editing, manual handle operation, and workpiece collection options improve usability.
Environmentally conscious design features include recyclable materials, elimination of hazardous substances, and energy-efficient control methods, contributing to eco-friendly operation.

Specifications and Performance

The M32 series features high spindle speeds (8,000 min-1), a chucking capacity of 32mm diameter, and a maximum machining diameter of 36mm.
It offers multiple tool stations, with spindle and back spindle drives rated at 6,000–8,000 min-1, and various motor options for different axes.
Power consumption and cycle times are optimized, with the new models demonstrating reductions in cycle time (up to 12.9%) and energy use compared to previous versions.
The machine’s layout supports flexible automation, including optional workpiece unloaders, chip conveyors, and long workpiece handling, streamlining production flow.

Control and NC Functions

The CNC system includes a 10.4-inch color LCD, with extensive program storage (up to 1200m), and supports advanced functions like variable lead threading, milling interpolation, high-speed rigid tapping, and 3D chamfering.
It provides a wide array of standard and optional features for precise, complex machining, including tool life management, geometric functions, and network I/O.
Additional capabilities include back spindle indexing, C-axis functions, and user macros, enabling sophisticated multi-axis machining and automation.

Overall, the Citizen M32 series combines high-speed, multi-axis machining with flexible tooling, advanced control systems, and eco-friendly features, making it suitable for complex, high-volume production environments.
