Haas CL-1

The Haas CL-1 is a compact gang-tool lathe for small parts: a 5C collet nose, 1 in (25 mm) of bar capacity, a 4 in (102 mm) maximum chuck and a 6,000 rpm, 5 hp (3.7 kW) spindle. Travels are 12 in (305 mm) in X and 8 in (203 mm) in Z, and Haas lists a starting price of US$54,995.

The proportions follow from the tooling. Haas describes it as gang style, in any combination, so the tools stand in a row and the X axis carries each one to the spindle centreline in turn. That is why X travel is half as long again as Z. A tool change is simply an X move at up to 757 ipm (19.2 m/min), with nothing to index. The number of tools is whatever fits along the slide without the next tool hitting the part, which is easy with 1 in bar and gets harder as parts approach the 4.95 in (126 mm) maximum turning diameter.

The spindle is belt driven with a 1.25 in (31.8 mm) bore. Haas's table includes C-axis figures: 160 rpm, positioning to 0.01°, interpolated motion and a holding torque of 3 ft-lbf (4.1 N·m). With holding torque that low, anything done with the spindle held on C has to be light. Thrust is 1,149 lbf (5,111 N) on both axes, and the table lists no spindle torque.

What sets the CL-1 apart for many buyers is how little it asks of a building. It runs on 220 VAC single-phase at 16 A or three-phase at 12 A, uses 1 scfm of air at 70 psi (28 L/min at 4.8 bar) and holds 13 gal (49 L) of coolant. It ships on a 78 × 62 × 80 in (199 × 157 × 204 cm) pallet at a listed 1,940 lb (917 kg). For scale, the ST-30 turning center ships at 10,900 lb (4,944 kg).
