5-axis-machining with Heckert continuous swivel head

New continuous horizontal/vertical milling head for machining centers Heckert; drilling, milling and tapping big work pieces under any solid angle, machining complex form elements with HEC 1000 to 1800 Athletic and BHC 3500 to 5500, optional NC-lathing.nnWith this milling head, Heckert (http://www.starrag.com/index.php/en/marken-heckert) has extended its broad variety of spindles for the machining centers HEC 1000 bis 1800 Athletic (http://www.starrag Saint Laurent clutch bags.com/index.php/marken-heckert/hec-1000-1250-1600-1800-athletic) as well as the BHC 3500 bis 5500 (http://www.starrag.com/index.php/en/marken-heckert/bhc-3500-4500-5500) . By means of the continuous H/V head, it is now possible to mill, drill and tap form elements such as surfaces and holes at any solid angle. In connection with an optional fast-rotating NC-rotary table as well as the spindle clamping and the tool receiver HSK-T 100, the machining centers are further able to perform the turning operation of a huge variety of contours.

The benefit of the continuous H/V-head is obvious: Even complex machining can be carried out in a single clamping set-up, which reduces production and processing times. Due to the fact that the H/V-head can be positioned wherever required within the +/- 180° swivel angle (0° = horizontal, 180° = vertical), even complex workpiece forms are cut with high-precision. In addition, the new machining head provides a time-saving and quality-increasing alternative to shift drilling because it allows, in the standard, machining with tools up to a length of 800 mm (optionally up to 50 kg tool weight and 80 Nm breakdown torque).

Further technical highlights: The H/V-head is equipped with a powerful 66 (84) kW/1860 Nm servomotor and a two-speed shift gearbox, so that the work spindle can rotate with up to 6000 rpm (optionally 8000) and manage a high stock removal rate. The swivel movement is realized by a direct drive, which needs only 0.9 seconds for a swivel movement of 180°. The absolute direct angle measurement system with travel resolution of 0.001° ensures a high degree of precision. With regard to the simultaneous 5-axis-machining, the torque is 1660 Nm. When milling and drilling at any angle, a hydraulic clamping ensures stability and security of the swivel and working position.

Regarding tool receivers, the operator can choose between HSK-A 100 and SK 50 form A and B, BT 50 and CAT 50 for milling and drilling YSL clutch handbags outlet. For turning, the interface HSK-T 100 is used. The coolant supply can be carried out via nozzles with 60 l/min or the spindle and tool center with a maximum pressure of 70 handbags outlet.
