Precise or dynamic machining of large components? Preferably: Both!

High precision, dynamics, and the best surface quality: The twin-spindle DZ 16 W has set new standards in the machining of complex workpieces in large quantities. This standard is leading CHIRON into a new dimension: With the new series 22 and spindle clearance of 600 mm, even large workpieces can be manufactured just as precisely and dynamically. For the first time, CHIRON will present the DZ 22 W five axis at the OPEN HOUSE ONLINE in May.

Housings for electric motors and transmissions, oil sumps, chassis components: Just like for large high-precision mechanical products, such as cooling elements or distributor housings, the following used to be true: High precision takes time. And high dynamics come at the expense of precision. The new CHIRON series 22 tackles this contradiction convincingly.

The basis for the innovative machine concept with small footprint of around 25 m2 is – like series 16 – a machine platform in a moving gantry design. The rigid machine bed and active component cooling enable the required degree of precision on the workpiece. High axis acceleration and fast rapid traverses ensure dynamic machining as never before seen with workpiece dimensions of this size.

In addition to precision and dynamics, series 22 also offers impressive flexibility. From very complex workpieces or product series with many different tools: The magazines offer space for up to 77 pieces and, thanks to the integrated workpiece changer, the workpieces are loaded and unloaded during machining operation and therefore extremely productively.

Two spindles – one fast, one strong

Depending on the processing task, two different main spindles are used in series 22: One fast spindle with a speed of up to 20,000 rpm and a torque of up to 110 Nm for workpieces made of aluminum or aluminum alloys. And a strong spindle with a speed of up to 12,500 rpm and a maximum torque of 200 Nm for hard materials and large tools.

Facts and figures

  • Travel distances X-Y-Z max. 620-650-600 mm
  • Spindle clearance 600 mm
  • Spindle speed 12,500 rpm / 20,000
  • Spindle torque up to 200 Nm / 110 Nm
  • Axis acceleration X-Y-Z max. 10-10-17 m/s²
  • Rapid traverse speeds X-Y-Z max. KGA 75-75-75 / LDA 120-120-90 m/min
  • Number of tools max. 2 x 77 pieces
  • Automatic tool replacement 3.5 s

Workpiece dimensions

  • Four-axis version (per working field) Dia. 680 mm x 1,330 mm, up to 600 kg
  • Five-axis version (per working field) 2 x Dia. 599 mm x 340 mm, up to 150 kg

Impressive on all counts

The working areas is easily accessible, and the process easy to see thanks to the large glazed doors. The control panel is located directly next to the working area, making set-up easier. The new machines are operated easily and according to context via the TouchLine operating system.

On the back, the tools are inserted in the chain magazine, and the tool data can be entered here directly via the operating console.

Tool replacement is carried out during machine operation; the new tool is clicked into the magazine with a single movement of the hand.

Modular design for application-oriented configuration

Series 22 is available with two drives: A ball screw drive or a linear direct drive. You can also choose from two plate variants: A suspension plate for four-axis machining or two face plates for five-axis simultaneous machining. All models can also be supplemented according to the application – e.g. with a cooling system, suction unit, chip conveyor, individual tool packages. To increase the degree of use, the specialists at CHIRON develop individual automation solutions together with the customer.

Even better with SmartLine

To tap the full potential of digitalized production, series 22 is prepared for the integration of various SmartLine modules – for a clear plus in terms of productivity, product quality and machine availability.

ConditionLine: Early detection of non-typical operating behavior and targeted planning of maintenance and repair

ProcessLine and ProtectLine: Reliable protection against machine crashes with a digital twin, both in preparation and during running operation

Presentation at the OPEN HOUSE ONLINE

The new series celebrates its premiere in May in a new way - at the OPEN HOUSE ONLINE. Here, CHIRON will inform you about the highlights of the DZ 22 W five axis and demonstrate the machining centre live under cutting.
