The new C 400 basic machining center
Hermle AG is presenting its new C 400 basic machining center at the AMB in Stuttgart. The new 5-axis machining center will be showcased at Stand D 52 in Hall 7.0, and is sure to find a place on the market thanks to its strength and precision. Hermle has drawn upon its proven core competence in 5-axis technology to develop the C 400 basic, which builds upon the tried-and-trusted modified gantry design using mineral casting and has 3 tool axes and 2 workpiece axes (NC swiveling rotary table). Since an increasing number of manufacturers are taking up this axis concept and extolling its suitability for 5-axis machining, we can assume that the concept has now established itself in the world of 5-axis technology. Thanks to the strength and precision of the machining center, a high machining volume can be achieved while retaining top precision and optimum surface properties. The mineral cast machine bed ensures the required static stability, this being reinforced by the center's four legs. Hermle's structure with the X, Y, and Z axes in the tool and the A and C axes in the workpiece has been tried and tested thousandfold on the market, creating a perfect 5-axis machining center thanks to the perfect interaction of all 5 axes. Workpieces of up to 2000 kg can be worked using 3 axes and workpieces of up to 600 kg can be machined with 5 axes, with traverse distances of X=850mm, Y=700mm, and Z=500mm. In particular, the large swivel diameter of 1000 mm between the side plates of the NC swiveling rotary table, which has a table top with a diameter of 650 mm (leveled on 2 sides to 540 mm), is a great benefit. It allows workpieces with a length or diameter of up to 1000 mm to be machined. The working area is unsurpassed in relation to the size of the machine and supporting surface. However, to enable machining that is both precise and strong, powerful main spindles are also required. Like always, Hermle has not compromised on the design of the C 400 basic. With speeds of 15000/18000 rpm (SK 40/HSK A 63), powerful milling spindles that ensure high machining volumes and the precise machining of quality surfaces are available. Naturally, both spindles are equipped with Hermle's patented collision protection system, which is extremely well regarded by customers. In the case of a collision in the Z-direction, the collision energy is absorbed by six displacement sleeves, which in many cases prevents the spindle from being damaged.
