CHIRON Group recently demonstrated for the first time its new 715 Series machining center. Designed for complete machining of all six sides of complex parts, the machine fits between the vertical CHIRON FZ 08 S mill turn precision+ machining center and the STAMA MT 733 machining center. It includes part handling automation and storage.
Matthias Efinger, Chiron Systems Engineer R&D, says “the goal during development was to create a machining center designed for autonomous processing on all six sides, rounding off the CHIRON Group bar machining portfolio and fully bridging the gap between the FZ 08 S mill turn precision+ and MT 733.”
The 715 Series is designed for fully automated, complete machining tasks in the medical technology, aviation and aerospace, energy, and automotive industries. Part size range is bars up to Ø 65 mm or chuck parts up to Ø 200 mm, with maximum workpiece weight of 20 kg.
Continuous machining process
Two versions of the machining center are available: CHIRON MT 715 and CHIRON MP 715 – MT is Mill Turn and MP is Multi Profile. The machines include a direct-drive 20,000 rpm milling head, a horizontal main spindle and a matched, opposing counter spindle to permit continuous multifunctional machining on all six sides of a part in a single setup. This capability is used to machine hip stems, turbine blades, and extrusions for chassis or battery storage.
Both machines accommodate 128 tools and include integrated workpiece handling and workpiece storage. This supports fully automated, cost-reducing manufacturing of workpieces in small and medium batch sizes. Convenient loading and unloading of the tool magazine can occur during machining.
High levels of automation
The new machine platform is also set up to integrate digital systems from the CHIRON SmartLine Portfolio, including automatic condition monitoring, integrated machine and process diagnostics, machining simulation, preventive machine protection in every mode of operation, remote diagnostics and remote maintenance, and intuitive operation.
Within the CHIRON Group portfolio there are a range of options for machining workpieces with up to a 200 mm diameter and a length of up to 500 mm, for milling and turning off the bar, or milling off the bar or from profile.
CNC machining centers and "Made by CHIRON" turnkey solutions guarantee high-speed manufacturing and CNC machining with maximum productivity and maximum precision. Whether with one, two or four spindle, machining centers from CHIRON produce components of the highest quality at minimum unit costs. Economical turnkey solutions for CNC machining, high-speed cutting and high-speed manufacturing permit "seconds ahead" production.
Related Glossary Terms
Cone-shaped pins that support a workpiece by one or two ends during machining. The centers fit into holes drilled in the workpiece ends. Centers that turn with the workpiece are called “live” centers; those that do not are called “dead” centers.
Workholding device that affixes to a mill, lathe or drill-press spindle. It holds a tool or workpiece by one end, allowing it to be rotated. May also be fitted to the machine table to hold a workpiece. Two or more adjustable jaws actually hold the tool or part. May be actuated manually, pneumatically, hydraulically or electrically. See collet.
- computer numerical control ( CNC)
computer numerical control ( CNC)
Microprocessor-based controller dedicated to a machine tool that permits the creation or modification of parts. Programmed numerical control activates the machine’s servos and spindle drives and controls the various machining operations. See DNC, direct numerical control; NC, numerical control.
- gang cutting ( milling)
gang cutting ( milling)
Machining with several cutters mounted on a single arbor, generally for simultaneous cutting.
- machining center
CNC machine tool capable of drilling, reaming, tapping, milling and boring. Normally comes with an automatic toolchanger. See automatic toolchanger.
Machining operation in which metal or other material is removed by applying power to a rotating cutter. In vertical milling, the cutting tool is mounted vertically on the spindle. In horizontal milling, the cutting tool is mounted horizontally, either directly on the spindle or on an arbor. Horizontal milling is further broken down into conventional milling, where the cutter rotates opposite the direction of feed, or “up” into the workpiece; and climb milling, where the cutter rotates in the direction of feed, or “down” into the workpiece. Milling operations include plane or surface milling, endmilling, facemilling, angle milling, form milling and profiling.
- milling machine ( mill)
milling machine ( mill)
Runs endmills and arbor-mounted milling cutters. Features include a head with a spindle that drives the cutters; a column, knee and table that provide motion in the three Cartesian axes; and a base that supports the components and houses the cutting-fluid pump and reservoir. The work is mounted on the table and fed into the rotating cutter or endmill to accomplish the milling steps; vertical milling machines also feed endmills into the work by means of a spindle-mounted quill. Models range from small manual machines to big bed-type and duplex mills. All take one of three basic forms: vertical, horizontal or convertible horizontal/vertical. Vertical machines may be knee-type (the table is mounted on a knee that can be elevated) or bed-type (the table is securely supported and only moves horizontally). In general, horizontal machines are bigger and more powerful, while vertical machines are lighter but more versatile and easier to set up and operate.
Workpiece is held in a chuck, mounted on a face plate or secured between centers and rotated while a cutting tool, normally a single-point tool, is fed into it along its periphery or across its end or face. Takes the form of straight turning (cutting along the periphery of the workpiece); taper turning (creating a taper); step turning (turning different-size diameters on the same work); chamfering (beveling an edge or shoulder); facing (cutting on an end); turning threads (usually external but can be internal); roughing (high-volume metal removal); and finishing (final light cuts). Performed on lathes, turning centers, chucking machines, automatic screw machines and similar machines.
