Starrag UK has released a 150-mm-diameter quill that extends up to 750 mm from the Heckert HEC 1800 machining center’s z axis spindle. It enables conventional rigid tooling to be used for deep internal machining tasks while maintaining the accuracy and quality of workpiece finishes, according to the company. It’s designed to consistently perform ultra-rigid, heavy-duty machining, such as milling, boring and turning, on large complex workpieces, such as valves and housings. The quill option is available on machines that have a table size of 800 mm or greater.
The extendable quill is designed to alleviate the need for extra long tooling. With the extendable spindle, the HEC 1800 is optimized for consistent milling, boring and turning on internal features in heavy-duty machining environments.
Features for the multi-axis HEC 1800 include a 1.8 m × 1.25 m table capable of accommodating workpieces 2,700 mm tall and up to 13 tons. It has X, Y and Z axes travels of 3,400 mm by 2,800 mm by 2,335 mm and the 84 kW spindle produces up to 12,500 revs/min and 1,500 Nm torque. Customization options include a range of horizontal and vertical four- and five-axis heads, chain or tower tool storage for up to 450 tools and a 400 revs/min NC rotary table for in-process turning.
