With the presentation of the machining center of high-performance 5-axis CNC C 42 or dynamic of completely new, applicable construction of a universal, the company Maschinenfabrik Berthold Hermle AG, specialist in precision machining centres and represented by Deltecocontinues its success story with its universal machining centers C series and 5-axis. With its proven design of gantry changed, the new C 42 U machining center dynamic is optimally integrated into the series C 20 C, 30 C types, C 40 and C 50.

Equipped with optimal routes of X-Y-Z 800/800/550 mm adapted to the maximum size of the piece and consequently designed for 5-axis applications, C 42 or dynamic represents the machining system ideal for applications requiring maximum accuracyminimum tolerances and surface qualities best, as in the sectors of manufacturing of tools and moulds, biomedical technology, aviation and space, navigation construction of machines and equipment, engines and racing technology, as well as supply industry.

(C) 42 U dynamic, new machining center for 5-axis of Hermle with modified gantry construction

building type, 5-axis gantry and adjustable table CN

Three axis in the tool and two axes in the piece; the construction of type portico modified - highly stable version made in cast iron ore-with excellent buffer characteristics and optimal support of principal axes; support to the two sides, as well as the drive tandem of the adjustable circular table CN; the Quad Roller guidance system and the main drive prepared centrally for axis and; and finally the angle of orientation of the axis with 130 ° or 260 ° ± in total - with this, the C 42 U - A dynamic presents a basic dynamic useful in a new dimension and is set as a reference to the functionality of the adjustable circular table CN.

The ring storage of tools integrated into the base body with space-saving, works according to the principle 'pick-up', change the tools in a fast manner (chip to chip time 4.5 seconds) and offers, in the standard version, space for 42 tools with accommodation SK40 or HSK A 63. There are optionally available additional stores with 43, 87 or 160 spaces for power machining completely highly complex parts or product family complete, or a variety of pieces loose without major process equipment.

The customer can choose between three drives of the main spindle with powers of up to 29 kW, pairs of rotation of up to 200 Nm and regimes of revolutions in 10,000, 18,000 and 25,000 rpm. Also in the case of tables, you can choose between four variants in accordance with the requirements:

Table sets of subject area of subject 1,050 x 805 mm and load maximum of 2,000 kilos table.
Table circular adjustable CN Ø 800 mm for loads of up to 1400 kg table
Table circular adjustable CN Ø 420 mm for loads of up to 600 kilos table (optionally more plate of secondary subject area of subject 930 x 490 mm)
Table circular adjustable CN 440 Ø mm for loads of up to 450 kg table (optionally more plate of secondary subject area of subject 920 x 490 mm)

Table tilting circular CN Ø 440 mm with integrated torque engine.

The drive tandem mentioned on the axis (rotating axis of the table) and the drive of pair in the axis adjustable circular tables CN Ø 800 C (rotating axis) and Ø 440 mm (adjustable circular tables CN ø 420 mm spindle drive) not only are responsible for the highly dynamic positioning, but also minimal unproductive time and a secure fixing in the desired position of machining.

(C) 42 U dynamic also highlights a work space more in comparison with the surface of placement, as well as the concept of management, on the basis of the relations of size of competitors. On the one hand, excellent accessibility to the area of work and thereby to fastening systems or parts, ensures smooth handling and a free work. For an ideal fall of chips, the workspace is designed without corners or edges' and for the transport of chips there are optionally a tape of hold-down extractor or extractor of scrapers. The control units are used two systems CNC Heidenhain iTNC 530 or Siemens 840 D sl. The novelty is the extremely convenient panel with screen 19 "adjustable up to 30 °. In combination with the control panel adjustable in height by ± 100 mm and the practical insertable tray, the management system can adapt at all times to the needs of each user, without that they required costly HVACR. Control units have the technique of safety integrated according to category 3 of EN 954-1. E-Messenger reports to the user immediately, thereby increasing the availability of the machine and reduces the production interruptions. If these cases, the teleservice, which offers a help as quickly as possible in the event of problems of programming and management is available.

The image shows the optimum accessibility of the service units to the back of the machine.

Automation devices

For the machining of high-performance CNC 5-axis C 42 U Center dynamic, available 'full range' of devices of automation as systems of exchange of pallets, storage of pallets, complete flexible manufacturing cell including flow parts, warehouse and material or solutions with robots or complete handling systems, in which case, the Hermle AG company can provide all the elements of first-hand through its subsidiary, Hermle-Leibinger Systemtechnik GmbH, and may carry out turnkey solutions in hand (Turn-Key).

In this case it is advantageous to the 42 U C dynamic is structured as a "hook machine", with support from three points included, that does not require any Foundation and carries completely. Individual units are free and accessible after opening the doors and in cases of repair or a failure of the spindle, are uncoupled just connectors and then you can develop the replacement quickly. In this respect also worth mention that protection against collision - with message collision warning - as also the shell continues to be both implement of emphasized, so that in the event of a collision of the spindle, need to replace only the shell of the spindle (valid for the 10,000 spindles and 18,000)which significantly reduces the cost of repair.
