Selecting Chiron Machining Centers for Production

CHIRON Group SE in Tuttlingen, Germany, is a global benchmark in vertical CNC machining centers. Selecting the right machine requires analyzing part geometry, hardness, dynamics, and annual volume.

The portfolio spans from compact 5-axis Micro5 centers to heavy-duty platforms for aerospace and automotive parts.

For small-to-medium batches, single-spindle FZ centers with fixed tables deliver high versatility and rapid changeover. For high-volume series manufacturing, twin-spindle DZ complexes with rotary pallet changers allow operators to load raw parts during active cutting cycles, eliminating idle time.

Single-Spindle Versus Twin-Spindle Machining: FZ or DZ

Chiron machine architecture is divided into FZ single-spindle centers and DZ twin-spindle centers. Single-spindle FZ models provide maximum kinematic flexibility, streamlined CAM programming, and fast adaptation to varying part batches.

Twin-spindle DZ machines incorporate two synchronized motor spindles cutting two workpieces simultaneously within identical fixtures. This doubles manufacturing output and cuts per-part production costs by 30 to 40 percent without expanding shop floor space.

Patented Chiron Basket Tool Changer Architecture

A hallmark feature of Chiron vertical machining centers is the patented basket tool changer system. The basket changer is positioned directly around the traveling spindle head, executing rapid radial tool exchanges in fractions of a second.

Chip-to-chip exchange times reach 1.2 to 1.5 seconds, with tool-to-tool exchange taking merely 0.9 seconds. This rapid cycling cuts idle time in drilling, tapping, and milling, maximizing series output.

High-Performance Motor Spindles and Ceramic Bearings

Chiron motor spindles are precision units with integrated synchronous liquid-cooled drives. Spindle speeds range from high-frequency micro-milling units running up to 60,000 rpm to high-torque spindles delivering up to 350 Nm of cutting force for heavy steel removal.

All Chiron motor spindles incorporate hybrid ceramic angular contact bearings with oil-air lubrication. Dynamic balancing to DIN ISO G0.4 minimizes runout. Inquiries should include the serial number from the machine rating plate.

Linear Roller Guideways and Ballscrew Feed Drives

Chiron machines operate with feed accelerations up to 2g and rapid traverse up to 90 m/min. Coordinate axes glide on preloaded linear roller guideways sized from 25 to 45 mm.

Axis movement is driven by hardened precision ballscrews with internal cooling to counter thermal growth. Direct Heidenhain optical scales ensure micron-level positioning.

Workpiece Pallet Changers and Pendulum Machining Mode

Chiron W-series models feature integrated 0°/180° workpiece changer tables with hydraulic Hirth coupling clamping. While the spindle operates on one station, the external fixture station is safely loaded without interrupting metal removal.

Table indexing takes 2.0 to 2.8 seconds, enabling continuous cutting. Five-axis FX models utilize dual-axis A and C rotary tilting tables powered by direct-drive torque motors for zero-backlash contouring.

Siemens Sinumerik and Heidenhain CNC Automation Systems

Chiron machining centers feature Siemens Sinumerik (840D sl, Sinumerik One) and Heidenhain (TNC 640, TNC7) controls. The TouchLine interface delivers real-time process monitoring.

Integration is supported via Profinet, Ethernet, and OPC UA. We supply CNC modules, Simodrive and Sinamics power units, I/O modules, encoders, and handheld panels.

High-Pressure Through-Spindle Coolant and Filtration

Thermal stability and effective swarf extraction are essential for sustained dimensional repeatability and long cutting tool life. Chiron platforms are outfitted with multi-stage high-pressure coolant pumping units supplying filtered emulsion through the spindle up to 70 bar.

Chip management features washdown perimeter flushing nozzles, heavy-duty scraper swarf conveyors, and fine-particle filtration systems. We provide genuine pump overhaul kits, Deublin rotary coolant couplings, filter media rolls, and protective telescopic guideway way-covers.

Machine availability, configuration options, production lead times, and shipping terms are determined upon technical review. Spindle, guideway, and tooling compatibility are confirmed against the factory serial number.
