Hendrick HHD-R Series

The Hendrick HHD-R Series is the heavy-duty line among Hendrick 3-axis CNC routers, and the one that can be built with two spindles. Standard tables are 8 ft x 4 ft (2,500 x 1,230 mm), 10 ft x 5 ft (3,100 x 1,560 mm) and 12 ft x 6.5 ft (4,020 x 2,050 mm), and Hendrick offers it either as a moving gantry or as a moving table machine. Custom table sizes and configurations are available.

Z travel is 13 in (330 mm). That is the tallest standard Z figure of the three 3-axis series, which matters for thick blocks, deep fixtures and the boring and saw units that hang below the head. Rapid traverse is 2,400 in/min (60 m/min) with cutting speeds up to 800 in/min (20 m/min), on precision ground helical rack and pinion in X and Y and a precision ball screw in Z.

One HSD HSK63-F high frequency spindle with an automatic rotary tool changer is the standard head. The option list is where this series separates from its siblings: a two spindle configuration with two 8 station automatic tool changers, independent head spacing by program, and two multi boring units. The larger boring unit carries 14 vertical and 6 horizontal spindles on 32 mm centers and two saw heads. Hendrick describes the line as carrying up to 16 tools.

Automatic tool length measurement, a multi-zone vacuum table with a Becker vacuum pump and pop-up location pins are standard, and the control is an OSAI Open CNC with a manual pulse generator. Spindle power is not printed for the series. With two heads cutting mirrored or identical parts at once, two parts come off each cycle without a second machine, but head spacing has to suit the part pitch, so check it against the nest.
