HAAS MULTIGRIND LLC identified manufacturers' desire for more effective "complete machining" of large workpieces — large diameter, long parts, with complex and precise features — with a single clamping. Examples offered include hob cutters, broaches, geared shafts, cutting rotors, landing gear components, turbine engine components, winch drives, racks and guideways.
"Combining multiple operations into a single clamping and into a single machine cycle has multiple benefits," the CNC grinding machine specialist explained; "higher overall precision, lower labor and handling costs, fewer … machines, reduced floor space requirements and faster overall throughput, to name a few."
The new Haas Multigrind® CB XL was based on the Multigrind® CB, with much of the same structural design but with a “stretched” X-axis and machine table.
The mineral cast bed as well as the high-precision linear drive in the machine table ensure stable processes and repeatable grinding results. There is room on the machine table for up to four work supports. Four telescoping doors simplify loading and unloading, as well as machine set-up.
The new Multigrind® CB XL is available in four incremental lengths for workpieces from 1400 to 3200 mm. The modular design also includes options for table extensions which can be configured for the specific requirements of individual customers and applications.
Other components and systems affecting performance and precision are available as options. Grinding wheel shapes are produced and maintained with on-board dressing spindles and automatic wear compensation, ensuring consistent precision.
For most applications the standard tool magazine with up to 15 wheels is enough. Beyond that, Haas Multigrind offers a shelf tool magazine with space for 65 grinding wheels up to 300 mm in diameter and up to 20 coolant nozzle sets.
Automatic part loading solutions are available, which are fully engineered, deployed and supported by in-house resources.
