DN Solutions LYNX 2100 LYB

The DN Solutions LYNX 2100 LYB puts a Y axis on the 8 in LYNX 2100 spindle: 105 mm (4 in) of Y travel alongside 205 mm (8 in) of X and 560 mm (22 in) of Z. The main spindle is rated 15 kW (20 hp), 169 N·m (125 ft-lb) and 4,500 rpm, and the live tools are listed at 6,000 rpm. It turns up to 300 mm (12 in) in diameter and 510 mm (20 in) in length.

The 8 in spindle matters on a Y-axis machine because of the blanks it holds. Stock large enough to need an 8 in chuck usually has real material to remove before any milling starts, and the 169 N·m (125 ft-lb) at the spindle is there for that roughing. The figure is about 33% above the 127 N·m (94 ft-lb) of the 6 in LYNX 2100 A and LYNX 2100 LA, in exchange for top speed: 4,500 rpm here against their 6,000 rpm.

Once the turning is done, the Y stroke lets driven tools work away from the centreline. On a part of this size that typically means bolt-circle holes drilled square to a milled flat, wrench flats cut to width in straight passes, or a keyway whose walls stay parallel. The stroke is 105 mm (4 in) in total, well short of the 300 mm (12 in) turning diameter, so check on the drawing that every off-centre feature of a large part falls inside it. DN Solutions' table does not say how the stroke is split either side of centre.

Against the turning-only LYNX 2100 B, which has the same chuck, speed, power and torque, this model has 560 mm (22 in) of Z travel instead of 340 mm (13 in) and weighs 3,900 kg (8,598 lb) instead of 3,100 kg (6,834 lb). The LYNX 2100 B turns a larger diameter, 350 mm (14 in), but a shorter length, 330 mm (13 in). The step up is the LYNX 2600 Y, with a 10 in chuck, 403 N·m (297 ft-lb) and the same 105 mm (4 in) of Y travel, at 5,750 kg (12,677 lb).

Plan the installation around 2,880 mm (113 in) of length, 1,711 mm (67 in) of width and 1,921 mm (76 in) of height. The live-tool drive is described by its speed alone, so heavy milling cuts should be discussed with DN before a job is quoted.
